1:54
were
2:00
perhaps really boring in the last
2:03
bunch of episodes that's going to drop next week. But
2:07
thus far, I've found it very enjoyable.
2:09
Yeah, yeah, I'm enjoying watching it.
2:11
But it's like, there's not really a couple
2:13
to root for this season. I
2:17
don't know about that. Okay, fair enough. Maybe
2:20
you're not as cynical as I am. I
2:22
mean, I like Izzy and Stacey. I think
2:25
they're cute. I
2:28
definitely think they're going
2:30
to have some issues to work out
2:33
related to them coming from different
2:35
class backgrounds. But we'll
2:38
see, we'll see. Yeah. Anyways,
2:41
let's move on to what people actually care about.
2:43
Fat Bear Week. Yes. As
2:45
you're listening to this, we
2:48
are in the midst of Fat Bear
2:50
Week. Let's
2:52
see, yeah. This will be dropping on Wednesday,
2:54
I believe. Voting
2:57
for Fat Bear Week is theoretically
3:00
supposed to start tomorrow
3:02
as we're recording this, October 3rd. And
3:07
a champion will be crowned on
3:09
October 10th. But currently,
3:12
I think some stuff is still up
3:14
in the air. Do you want to talk about that?
3:17
Well, whenever I was looking at the website
3:19
earlier, it did say that they were going
3:21
to have the bios
3:24
and announce the bears in the running
3:26
tonight.
3:26
Okay. So Monday,
3:29
October 2nd at 7 p.m.
3:31
Eastern time is what I saw.
3:33
So that has not occurred as
3:36
per this recording yet, but
3:38
it will have occurred. So we'll
3:40
see. We'll see if there are some of our faves
3:42
from the last years back up or
3:45
if we have some fresh meat in there.
3:48
I did look at the junior
3:51
cub that recently was crowned. Yes.
3:55
And he is stupendous, the good
3:57
bear. Yes. Spring Cub 806.
4:00
very good, he got very
4:02
fat and we're so happy for
4:04
him.
4:06
Just as some background, if this is
4:08
your first year listening to the Stronger by
4:10
Science podcast, this has become a bit of
4:12
a yearly tradition around these parts. The
4:15
Katmai National Park in
4:18
Alaska has
4:21
a competition every year
4:24
called Fat Bear Week that, you
4:26
know, I'm honestly not sure what purpose it serves,
4:29
maybe just to bring attention to
4:31
the park, maybe
4:33
sell some merch, whatever, but
4:36
it also brings awareness to a very
4:38
important issue in
4:41
the earth sign community, which
4:44
is that bears have to get very fat because they hibernate
4:46
and they need plenty of fuel
4:50
in their body to get them through the winter. And
4:52
so every year they run this
4:54
little competition, it's a bracket, anyone
4:57
can vote where you basically
5:00
just vote on which bear you think
5:02
got the fattest or just who,
5:05
which bear's bulking
5:08
journey you enjoy the most
5:12
and they crown a winner. So
5:15
yeah, that's going to go
5:17
on. It almost got either
5:19
canceled or postponed due to
5:22
the government shutdown that I think
5:25
is going to be averted. I believe so. But
5:28
yeah, like it's a national park, so it's federally
5:30
funded. All of the
5:32
employees' salaries, including
5:35
the people who would be doing all of the Fat Bear stuff
5:37
on the website, comes from
5:39
federal money. So if the government
5:41
would have been shut down, those people would
5:43
have been furloughed and
5:46
yeah, the competition would have been postponed
5:49
or canceled this year. But
5:51
yeah, that isn't going to happen, but
5:54
I do think they're a little bit behind as a result because
5:56
all of that was up in the air for a while. So
6:00
yeah, Lyn's just from just
6:03
from like history or memory. Do
6:05
you have any any bears that you're pulling
6:07
for this year, even though they haven't announced
6:09
all of the contestants? Well 747
6:10
won last year, right?
6:14
And I was looking back at his before
6:17
and after from last year, and honestly,
6:21
incredible work by him. Yeah.
6:24
So I'm looking forward to seeing
6:26
an update. But you know, I would love to see
6:28
some new bears
6:28
in the mix. Yeah, I'm
6:30
a big fan of Grazer, as
6:33
we've talked about in previous
6:35
iterations of Fat Bear Week content. But
6:38
I also think if you're a betting person,
6:41
it's hard to pick against 480
6:44
Otis. Yeah,
6:46
another reigning champ. Yeah, he's
6:48
won four times. And
6:51
you know, I won't pretend like
6:54
I'm a year round Fat Bear
6:56
fan. Like there are cameras
6:58
in the park that you can just like watch
7:00
a live stream of. That's not
7:02
me. Like I'm not that dedicated to the cause. Now
7:04
I did find a YouTube channel that curates
7:07
the best from those live
7:08
cams. Because I wanted to check out 806
7:11
spring hub
7:13
and see a bit more of his journey. And
7:16
yeah, there's people out here doing
7:17
the Lord's work of watching the bear
7:20
cam and clipping and
7:22
giving you like four minute videos on YouTube,
7:25
if you are interested in that. Honestly
7:27
send that to me. I will. Also,
7:29
can you post that in the show notes? I will. Yeah.
7:32
Hell yeah. But yeah, what I
7:35
was gonna say is like, I feel like 480 Otis
7:37
for a casual Fat Bear fan like me.
7:40
Yeah. It's kind of like being an NBA
7:42
fan in the 90s, where it's just like, yeah,
7:45
you don't follow the off season. You don't know what moves
7:47
were made, but like going into the year,
7:49
it's like, I assume the Bulls will be
7:51
good again. That's, that's how I feel
7:53
about Otis. Yeah. But
7:56
yeah, yeah, we'll see. We'll see. It
7:58
should be another. exciting
8:00
week and another great fadbear season.
8:03
Yes, very exciting. Okay,
8:06
so we are about to
8:08
get into the plugs and start the episode,
8:11
but before we get rolling I just want to make
8:13
one quick note, and that
8:15
is that next episode we
8:18
were aiming for it to be a crowd
8:20
pleaser. So
8:23
this is the third part of our micronutrient
8:25
series, and we realized
8:27
that that is not the topic
8:30
that everyone is the most
8:32
interested in. I
8:35
think it's cool. I think it's been some good content.
8:37
I've learned a lot, yeah. But yeah,
8:39
like the listener numbers are down, like
8:41
I can take that on the chin. Honestly, I kind of
8:43
expected it. So
8:46
next episode we want it to be stuff
8:49
that you are very interested in
8:51
and very invested in, so we are going
8:53
with an all Q&A episode. So the
8:56
episode will
8:58
be as interesting to you as your
9:01
desire to submit a question that you want
9:03
an answer to. So ask
9:05
good questions and it'll be a good episode. If
9:08
you have a question that you'd like us to
9:10
address on the podcast, it could be about anything.
9:14
Record a voice
9:16
memo 30 to 60 seconds
9:18
and email it to podcast at strongerbyscience.com,
9:23
and if we like your question
9:25
we'll answer it all in the next episode. So
9:29
yeah, I think that's it for
9:31
housekeeping notes. Let's
9:33
get into our plugs.
9:34
Yeah, so if you're enjoying the show,

go through all of the studies published
11:52
for anyone who's
11:54
interested in getting stronger, getting
11:56
more jacked, getting leaner, whatever. If
11:59
you wanna keep up. day with the research mass
12:02
I think is the best way to do
12:04
it. And if
12:06
you would like to get a little

r slash Stronger by Science. That
12:27
is the best place to go. Either
12:30
of those places is the best place to go if
12:32
you'd like to stay abreast of all of
12:35
the things going on, especially related
12:37
to the podcast. So we
12:39
are, for instance, going to be answering
12:42
your micronutrient related questions
12:44
at the end of this episode. And
12:46
the way that you would have known that we were going
12:49
to do that and to submit questions on
12:51
that particular topic would have
12:53
been to join the Facebook group and subreddit. That's
12:55
where we put out the call. So, yeah, those
12:57
are those are good places. You should check them
13:00
out. And then finally, just kind
13:02
of I already mentioned this, but just standard
13:05
plug here at the end. If you have
13:07
questions for the podcast, record
13:10
a 30 to 60 second voice memo.
13:13
Don't exceed 60 seconds. We will not listen
13:15
to it. 30 to 60 seconds,
13:17
though, that's that's a sweet spot. Under 30
13:19
seconds would also be fine. Yeah,
13:21
but like no one actually does that. No
13:25
one's concise. Yeah, I'm a Stronger
13:27
by Science fan. I can't
13:30
judge anyone for that. I know. But
13:32
yeah, yeah. Record a voice clip and email
13:34
them to podcast at Stronger by Science
13:37
dot com. All right. Let's let's
13:39
get into it.
13:40
Yeah. Like you mentioned today, we are
13:42
wrapping up the three episode
13:44
micronutrient series.
13:46
So the first episode we published covered
13:49
micronutrients themselves, what they
13:51
are in their history. The second episode
13:54
discussed nutrient targets, where
13:56
those targets come from and what they mean.
13:59
And this episode. we want to get a little bit
14:01
more practical and discuss which
14:03
micro-dutrients are most worth monitoring
14:06
if you want to do that and
14:08
why you shouldn't allow a focus on micro-dutrients
14:11
specifically to detract from the pursuit
14:13
of a generally healthy diet. Absolutely,
14:16
and just so you know, all of the
14:18
things I'm about to mention will be linked in the
14:20
show notes, but there is a five-part
14:24
article series on micro-nutrients on
14:26
the macro-factor website, the
14:29
kind of landing page for all of those articles
14:31
will be linked in the show notes, and this
14:33
article or this episode in particular
14:37
mostly covers content from the
14:39
last two articles in that series,
14:41
which will also be linked in the show notes. And
14:44
lastly, if you would like
14:46
to read more about each
14:49
particular micro nutrient, we
14:52
have just a page
14:54
of content on
14:57
each of those micro nutrients
14:59
in the macro-factor knowledge base and kind
15:02
of the the landing page for that will be linked in
15:04
the show notes as well. So if you want
15:06
to know kind of how easy
15:09
or difficult it is to track a particular nutrient,
15:12
the general likelihood that
15:14
you might be consuming too much or too little
15:16
of that nutrient, good dietary
15:18
sources of nutrients, etc. Those
15:22
are the sorts of things on each of those micro
15:24
nutrient pages and yeah,
15:26
kind of the the homepage
15:28
for all of those will
15:30
also be linked in the show notes. Yeah, that's such an excellent
15:32
resource that you put together. Thank you. And it's
15:34
not just for macro-factor users, obviously
15:37
the Strong by Science audience could
15:39
get a lot out of that as well.
15:41
I hope so. So yeah,
15:44
today we're gonna talk about micro
15:46
nutrients that are most worth monitoring.
15:49
So I think to set us up for answering
15:51
that question,
15:52
Greg, will you tell us what
15:55
the difference is between an insufficient
15:57
intake and a deficient intake?
15:59
I feel like this is something that probably
16:02
is going to seem obvious once people learn
16:05
it, but it's not always
16:07
in the conversation when you hear
16:09
about micro-dutrients. Yes. I
16:12
think I touched on this in the last
16:14
episode, but just to make
16:16
this more explicit at the start
16:18
of this episode and to kind of frame
16:21
everything we're about to talk about next, I
16:24
think that it is... I
16:27
think terminology matters in this discussion
16:30
and very frequently when
16:33
people talk about consuming a
16:35
little bit less of a particular nutrient
16:37
than the RDA or the EAR or the AI or
16:42
whatever, there's
16:44
a tendency for folks to use the term
16:47
deficiency, like you're not consuming
16:49
quite enough, therefore you're deficient in this nutrient.
16:52
But that is not the best term
16:55
to use most of the time. Generally
16:59
insufficient or inadequate intake
17:01
is how you would see that
17:03
described in the research and by public health
17:05
bodies. And the reason for that is there
17:08
is a big difference between
17:11
insufficient intake and deficient intake
17:13
or having a nutrient deficiency.
17:19
Just in general, if you have a
17:21
micronutrient deficiency, there
17:24
will generally be something
17:27
extremely wrong that's very
17:29
noticeable. The example I gave
17:32
in the last episode is with calcium.
17:34
If you have a calcium deficiency,
17:39
oftentimes one of the first things that'll happen is there
17:42
will be errors and kind of
17:44
the rhythmicity or signaling in
17:46
your heart and they can cause heart failure.
17:51
If you have insufficient calcium
17:53
intake, it's still not ideal, but
17:55
the normal consequence of that is you
17:58
might have a slightly higher risk of osteoarthritis. over
18:01
your lifespan. So
18:03
two very, very different things. And
18:06
at least in most developed
18:08
countries, micronutrient
18:11
deficiencies are very rare,
18:14
but insufficiencies are considerably
18:17
more common. And so in this
18:19
episode, we're going to talk about the
18:25
nutrients that people over-consume,
18:27
but then also under-consume.
18:29
And when we're talking about risks or rates
18:32
of under-consumption of those nutrients, we
18:34
are talking about insufficient
18:37
intake, not deficient intake.
18:40
An analogy that I think is
18:42
helpful here is if you think about it in
18:44
terms of a car, consuming adequate
18:47
amounts of a nutrient is
18:49
like taking extremely good care
18:51
of a car. You're getting top-of-the-line oil,
18:54
the best tires, the best
18:57
brakes you can get, always putting in
19:00
high-octane fuel, getting really consistent
19:02
tune-ups, etc. And so, you
19:05
know, like
19:08
going, like doing really, really good.
19:13
Insufficient intake, it's kind of like taking
19:17
what I would often consider to be like
19:19
normal care of a car, but... It depends
19:21
on someone's definition, probably. I
19:24
like how a teenager would take
19:26
care of their car. Or
19:28
just like people of maybe lower
19:30
socioeconomic status. That's kind of
19:32
my context. So,
19:36
you know, you're still taking it in for an oil
19:38
change every 5,000 miles, but maybe
19:40
sometimes you push that to 6,000 or 7,000, you're
19:44
getting the tires changed, but maybe they're getting
19:46
worn down a little bit too much occasionally.
19:50
And so, like, the consequence there
19:52
is the car probably won't run quite
19:54
as well as it would if you took really,
19:56
really good care of it, and it might break down...
19:59
Little bit like it might need to be serviced
20:02
a little more often it might end up breaking
20:04
down a little bit sooner but like Generally,
20:06
it's still going to have a pretty good life Like
20:09
things are going to work pretty well most of the time
20:11
and then like Deficiency
20:13
is kind of like just never changing the oil which
20:16
like the car will putter along for a while But eventually
20:19
like something is going to break very badly
20:22
and it's gonna be fucking obvious So
20:25
yeah, like that's I think
20:27
not a terrible analogy. I like that.
20:29
I mean, thank you. That's a perfect So
20:32
yeah, like I'm like we're talking about Insufficient
20:35
intake here. We're not talking about deficiencies
20:40
so for everything we're
20:43
about to talk about we're just
20:45
kind of gonna kind of go down a list of Things
20:48
that people might consume a bit too much of
20:51
maybe not quite enough of But
20:53
everything we're about to cover here I made
20:56
a handy table for that will
20:58
be linked in the show notes if you want to refer back
21:02
And you know, like I don't know how long this episode
21:04
is going to be hopefully it's last it's shorter
21:06
than the last two but It's
21:09
probably we don't have a great track record. That's
21:11
true Like it's probably still gonna be at least like 90
21:13
to 120 minutes of content And
21:17
so yeah If you'd like a resource
21:19
that you can glance back at for 30 seconds
21:22
instead of needing to relist into like an hour of content
21:25
a Table that will
21:27
like summarize all of this
21:29
will be linked in the show notes So,
21:33
yeah, let's uh
21:35
Let's get into it. Yeah so
21:37
we're gonna talk about three groups of micronutrients
21:40
to pay close attention to Nutrients
21:43
that are often over consumed nutrients
21:45
that are often under consumed and nutrients
21:48
that vegans in particular
21:49
May want to pay close attention to so
21:52
Greg. Let's
21:52
start with those that
21:54
are over consumed. Yeah,
21:56
so Just like one
21:58
like very small group correction
22:00
there. Some of these
22:02
that are often over-consumed are
22:04
just like kind of general nutrients,
22:07
like not specifically micronutrients, which
22:10
like very, very small correction. But
22:13
I don't want anyone writing in and being like, Greg
22:15
said saturated fat was a micronutrient.
22:19
Anyway, we understand the distinction. But
22:22
yeah, so in kind of the standard
22:25
Western diet, there are a handful
22:27
of nutrients that are often over-consumed.
22:30
And there are a couple that I think
22:33
a lot of people believe are frequently
22:35
over-consumed, but maybe
22:37
aren't so much. And I'm
22:39
going to touch on those as well. But
22:42
the first on this list is added sugar.
22:46
The recommended intake differs
22:48
depending on what source you look at, but
22:50
the USDA here in the US
22:53
recommends added sugar to comprise less
22:55
than 10% of total energy intake.
22:58
The American Heart Association recommends less
23:00
than 5% of total energy intake.
23:04
Actually, I don't think that was their exact
23:07
recommendation. I think they recommended a
23:09
number of grams per day to stay
23:12
below, but it was consistent with a 2,000 calorie
23:15
diet for women, 2,500 calorie diet for men, and
23:18
it would be less than 5% of energy in those
23:20
two diets. So just kind of like
23:22
abstracting at less than 5% of total
23:24
energy. And the British NHS
23:27
recommends to keep it below 30 grams per
23:29
day. So don't
23:32
consume a ton of added sugar. That's the
23:34
basic takeaway. An
23:36
average intake in most of the developed
23:39
world, it differs country to country, but it's
23:41
somewhere around 8% to 15%. So
23:45
some countries in Europe are down closer
23:48
to 8%, 9%, which would kind of come
23:50
in under that recommendation from
23:52
the USDA, but would still exceed the
23:55
American Heart Association and the NHS's
23:57
recommendation, 15%. is,
24:00
that's like quite a lot, like 15% doesn't
24:02
sound like a big number, but that's basically
24:05
like a sixth of your total energy intake
24:07
from added sugar. Also,
24:10
I think that there is
24:13
the general perception
24:15
that added sugar intake is increasing
24:18
over time and that that's like
24:21
driving a lot of disease
24:23
burden and whatnot. And like added sugar
24:25
intake is generally still too high, but it
24:27
is, it's actually trending down. It
24:30
peaked in the early to mid 2000s and
24:33
as there has been more awareness about,
24:35
hey, maybe don't consume
24:38
that much sugar, it is like gradually
24:40
trending down, but on average,
24:42
a lot of people are still consuming too
24:45
much of it. Moving on, saturated
24:47
fat. The
24:49
recommended intake from most health bodies is
24:51
to keep saturated fat intake as low as possible,
24:55
but to definitely try to keep it below 10% of
24:57
total energy intake. The
25:01
average intake in both the US and EU
25:04
is higher than that. And in
25:06
America specifically, only about a third
25:08
of Americans meet that recommendation
25:11
to keep it below 10%.
25:14
And
25:15
I'll note about this, like this
25:18
recommendation is more
25:21
controversial than I think it should be like
25:24
there is in kind
25:27
of like the online fitness and
25:29
nutrition space, a relatively large
25:33
group of folks who are who tried
25:35
to push the idea that all of
25:38
that is bullshit and saturated
25:40
fat is totally fine. Doesn't
25:42
increase your risk of cardiovascular disease
25:46
might increase your LDL cholesterol, but like
25:48
that's irrelevant. And
25:53
like, this isn't like, I'm
25:55
probably not the person to do
25:57
like an in depth episode on
25:59
this. And like this definitely isn't the podcast
26:02
episode to get super in-depth on this topic,
26:04
but like that's just fucking wrong.
26:07
Yeah like So
26:10
kind of starting with epidemiological research
26:12
and like the stuff I'm about to reference
26:14
will be linked in the show notes Higher
26:17
intakes of saturated fat are associated
26:19
with greater risks of cardiovascular
26:22
disease greater
26:24
intakes of saturated fat Like
26:27
directly increase LDL cholesterol
26:30
and there's also like pretty strong meta
26:32
analytic evidence that lowering LDL cholesterol
26:36
reduces rates of cardiovascular
26:39
disease in a predictable
26:42
Way with like a strong dose response
26:44
relationship, which like Very
26:48
very very strongly suggests
26:50
that we're dealing with a causal relationship
26:52
here So yeah,
26:55
like limiting saturated fat intake
26:57
is a good thing and
27:00
Yeah, more more people should probably pay
27:02
a bit of mind to that because
27:04
most people do seem to overconsume it moving
27:08
on another one that might be like somewhat
27:11
controversial and I Understand
27:14
the controversy around this one a bit
27:16
more and that is sodium. Mm-hmm So
27:19
like different public health bodies have different recommendations
27:22
for sodium but most of them
27:24
suggest That sodium intake
27:26
should be somewhere around like two
27:29
two and two and a half grams per day So
27:32
like 2,000 to 2,500 milligrams per day. Like
27:34
it's it's usually expressed in milligrams An
27:38
average intake in most developed countries
27:40
is like way way higher than that. Yeah
27:43
for understandable reasons like Well
27:45
seasoned food is delicious. Yeah Better.
27:49
Yeah, so one
27:51
perspective on this is that
27:53
that recommendation is Too
27:58
low or at least should be the
28:01
kind of like circumscribed
28:03
a bit more and like given like
28:05
more
28:07
kind of like context around it. So
28:10
some folks will make the case that
28:12
the only reason that you should
28:15
worry about sodium intake is
28:17
if you have high blood pressure and
28:19
like sodium sensitive hypertension in
28:21
particular. And a lot
28:24
of people have hypertension, but not every
28:27
hypertensive person has
28:29
like sodium sensitive hypertension. And
28:32
so they would suggest
28:34
that like most people are fine
28:37
to consume a lot of sodium, but
28:39
like consuming a lot of sodium has like
28:42
excess deleterious effects
28:44
specifically for, like
28:47
specifically for sodium sensitive hypertensives.
28:50
Yeah. So that's
28:53
one way to look at it. And that is,
28:55
I don't know, until about
28:57
a year ago, I think kind of the camp
28:59
that I was in. And I'm
29:01
still sympathetic to
29:04
that way of viewing things. But you left
29:06
the camp. Are you trekking to a new
29:08
camp? I don't know. Like I'm, I
29:10
don't think I have a strong take on it anymore.
29:13
Okay. So there was a meta
29:15
analysis that came out like, last
29:18
year, two years ago, like relatively recently
29:22
that suggests that
29:24
high sodium intake
29:27
is related to like stroke
29:29
risk. And there's
29:31
also like quite a bit
29:33
of animal research that's being done, finding
29:38
that high salt intake is
29:40
like mechanistically linked
29:42
to like disease mechanisms
29:45
related to the kidneys, brain, vascular
29:47
and immune systems. And
29:50
so like that stuff will be linked in the show notes
29:52
as well. And so like, you
29:54
don't wanna draw like too straight of a line
29:56
between animal research and human
29:58
health outcomes. And the
30:01
stuff with stroke risk,
30:03
it could be similar to the sodium
30:05
sensitive hypertension thing where hypertension
30:09
is a risk factor for having strokes. So
30:11
it could just be that people who consume a lot of sodium,
30:14
most of them are fine. They're not actually elevating
30:16
their individual stroke risk, but kind of on a
30:18
population level, you're
30:21
consuming more salt. Some of those people
30:23
will be more sodium sensitive and
30:25
they have an individual
30:27
large elevation and stroke risk and so you
30:30
get kind of those epidemiological trends.
30:32
Like that is certainly a possibility or
30:35
some more of like the animal mechanistic
30:37
stuff could be at play here and there is
30:40
like a driving causal
30:42
factor beyond simply potential
30:45
effects on blood pressure.
30:47
So yeah, like I'm
30:49
sort of in the middle of those
30:51
two perspectives right now. Like it's
30:53
something that to have a strong
30:55
take, I feel like I would need to dig much
30:58
deeper into the research than I have
31:00
to this point had time to dig. Have
31:03
you changed your sodium intake or your
31:06
personal habits? No.
31:10
Yeah, I'm not concerned enough
31:13
to modify my own salt intake. But
31:17
that may be one of the reasons, like just being completely
31:19
transparent. That may be one of the reasons I haven't
31:21
dug into this more because I
31:24
like salty food and I don't
31:26
want to be worried every
31:28
time I eat salty food. So yeah,
31:30
whatever. I don't know. Yeah. But
31:33
yeah, just in general, like given
31:35
the public health guidelines related to sodium,
31:38
like most people do over consume it. So
31:41
those are the three that
31:45
are where overconsumption is like
31:47
very common. There
31:49
are two nutrients
31:51
here that I suspect a lot
31:53
of listeners would have expected me to
31:56
include on this list that I did not. And
31:58
the first potential. The potentially controversial exclusion
32:01
is omega-6s. And
32:05
the reason I say that's potentially controversial
32:08
is there's currently
32:10
a lot of panic about seed oils. And
32:15
omega-6 fats, like linoleic acid
32:17
in particular, is the dominant
32:19
fat in seed oils. And
32:23
this is also not the episode to
32:25
get super, super into
32:27
seed oils. But
32:29
yeah, so the reasons that people are concerned
32:33
about it is I think that there's
32:36
the general perception that
32:40
high intake of omega-6 fats directly
32:43
causes an increase in inflammation, which
32:46
is not necessarily the case. It's
32:49
considerably more complex than that. And
32:53
I think the way, so a
32:56
lot of research, like back in the
32:58
day, maybe like 10, 15 years ago, was
33:01
looking at omega-3 to omega-6
33:03
intake ratios and finding a higher
33:06
ratio of omega-6 to omega-3
33:08
intake was associated with
33:10
higher levels of inflammation. And
33:13
I think the way that that research is kind
33:16
of leaning now is that when
33:19
you're dealing with ratios, you have both a numerator
33:21
and a denominator. Like you're
33:24
dealing with two numbers. So
33:26
you could have a high omega-6 to omega-3
33:28
ratio if you're consuming a lot of omega-6s or
33:31
if you're just not consuming that many omega-3s. And
33:34
I think the way that things tend to be leaning
33:36
now is that under-consuming
33:39
omega-3s was
33:42
the primary driver of those research
33:44
findings. Like if you consume a lot of
33:46
omega-6s but also a lot of omega-3s,
33:49
that's fine. And
33:51
if you don't consume that many omega-6s but you
33:53
also don't consume many omega-3s, that's
33:56
also not great.
33:59
So yeah.
33:59
That's the first thing. The
34:03
reasons that people are concerned related
34:05
to inflammation, I think, was largely
34:07
based on the omega-6 to omega-3
34:10
ratio stuff. It's
34:13
just an area where the bulk
34:15
of the research kind of looks
34:18
at it with a more updated, nuanced
34:20
lens, where it seems to be more about
34:23
total omega-3 intake instead of that ratio.
34:26
And then the other
34:29
thing is there are some kind of, there
34:33
are some animal studies that look very scary
34:37
and there are some small cohort studies
34:40
that some people get concerned
34:42
about. But when you zoom out and
34:45
look at just the totality
34:47
of the human research, there
34:50
are a lot of people consuming a lot of omega-6s
34:52
out there and when we look to
34:54
see what their actual chronic disease
34:57
burden looks like or what their mortality outcomes
34:59
look like, generally
35:02
consuming a lot of omega-6s are
35:05
associated with pretty neutral effects on
35:08
health and mortality outcomes. Or in
35:12
the case of some outcomes, like maybe small
35:14
positive effects, there was a
35:16
Cochran review on that in 2018 which
35:19
will be linked in the show notes. And like I said,
35:22
this really isn't the episode to get super,
35:24
super in depth on this. But
35:27
if you would like
35:29
a very in-depth treatment on
35:32
the kind of like con case
35:35
for, if like
35:37
the pro cases, omega-6s are
35:40
dangerous and people over consume seed oils
35:42
and that's killing everyone. The
35:44
like, the anti-case for
35:47
that, there's a
35:49
really good article on thenutrivor.com
35:52
about this and
35:55
I follow that guy on Twitter, Nick Hebert,
35:58
and he has been. One just like,
36:02
so a lot of the anti-seed oil
36:05
folks are just like, hmm, it's
36:07
crazy. No one will debate us
36:09
on this topic from kind of the
36:11
establishment, the people that hold the view that
36:14
seed oils are fine. He
36:16
responds to all of them. I
36:19
discovered him because I
36:22
followed some of those quacks that are super
36:24
anti-seed oil. He just
36:27
kept popping up in the responses. I was like,
36:29
oh, this guy seems like really annoying
36:31
to people that I find very
36:33
annoying. So like, let me just follow him,
36:36
like see what he's about. And
36:38
yeah, so he, everyone who's like, oh, why will
36:41
no one debate me? He's like, I'll fucking debate you and
36:44
all of them turn him down. Anyway,
36:47
it's just kind of fun. And he has a really good article
36:49
on his website about seed oils that
36:52
will be linked in the show notes. The
36:55
other potentially controversial
36:57
exclusion for nutrients
37:00
that are over-consumed is trans fats. Not
37:04
because just consuming
37:06
a bunch of industrially
37:09
produced trans fats is good, but
37:11
because most people don't actually consume like
37:13
many, if any industrially
37:16
produced trans fats anymore. This
37:19
was a fun thing I learned when I
37:21
was just like doing reading
37:24
for the micronutrient
37:26
pages in the macro factor knowledge base.
37:31
Most industrialized countries have
37:33
completely phased out trans fats
37:36
in foods. So
37:39
like food manufacturers
37:42
used to like trans fats because they were cheap to
37:44
produce and they increased the shelf stability
37:46
of foods. And they also like just
37:49
had, they improved like texture and
37:51
mouth feel and whatnot. There's
37:53
some research showing that like, yeah, they're not good. They
37:55
increase inflammation, they increase heart disease
37:57
risk, blah, blah, blah, whatever. And
38:00
for once, the United States actually
38:03
led the charge on a consumer
38:05
protection issue and
38:08
passed legislation, I think in like 2017, 2018, saying
38:10
they need to be phased out. And
38:13
they did, I think, grant an
38:15
extension. I think they were supposed to be phased
38:18
out in 2020, but they ended up being phased
38:20
out in 2021. They
38:22
were like, we need the CRISCO during COVID. I
38:24
guess so. No, I think it
38:26
was just like, yeah, supply chains are fucked up,
38:28
whatever. We'll give you a bit more leniency.
38:32
But yeah, the EU followed suit soon
38:34
thereafter, Canada,
38:36
and I think Australia did
38:39
as well and
38:42
wrapped up their phase out like earlier
38:44
this year.
38:46
So yeah, like trans fats just like aren't really
38:49
much of a thing anymore in most products.
38:53
Now there is a new like
38:56
industrial process that has replaced
38:58
the process of partial hydrogenation which
39:00
was what made the trans fats before, which
39:04
is I think biochemically quite interesting.
39:06
It's called inter esterification. So
39:09
basically,
39:11
instead of making solid
39:13
fats with a relatively lower saturated
39:16
fat, like that
39:18
was another benefit of trans fats. So
39:21
trans fats are technically unsaturated
39:24
fats, like they're structurally
39:26
and functionally similar to saturated fats. But
39:30
they are like, they
39:32
must be unsaturated. Like
39:37
that's like definitionally what it means. Like you
39:39
have a
39:42
trans configuration of a double bond instead of
39:44
a cis configuration of a double bond. They're
39:47
unsaturated fats like consumers had been taught
39:49
to be fearful of saturated fats. So
39:52
they gave food manufacturers like a way
39:55
to put fats in foods that
39:58
had the same like functional out there. comes
40:00
as saturated fats like improved shelf stability
40:02
blah blah blah whatever but consumers
40:05
wouldn't see saturated fat on the food label
40:07
because they weren't saturated
40:10
so inter esterification is like
40:12
a new process that food manufacturers are
40:14
using to accomplish the same thing where
40:18
essentially like so triglycerides
40:20
which is how most fats are kind of
40:22
like stored functionally is
40:25
a glycerol backbone with three fatty
40:28
acids attached to it and
40:30
if you have I think one
40:33
saturated fat in the middle
40:35
of that glycerol backbone and then two
40:37
unsaturated fats like one on either side
40:40
so like within
40:42
the triglyceride you do have a saturated
40:45
fat molecule in it it'll
40:47
still wind up being solid at room temperature
40:50
and like behaving as if it was a saturated
40:52
fat even though like two thirds
40:55
of the actual fatty acids are unsaturated
40:58
so that's that's the process they're using now
41:01
to kind of create the trans
41:03
fat like effect without
41:05
trans fats
41:07
and like
41:08
I don't know like it biochemically
41:10
I can't think of a reason that it would
41:12
be scary and bad
41:14
like trans fats were but who
41:16
knows like in 10 years we might find out yeah
41:18
that's bad too yeah but yeah so
41:21
that that's how they were able to phase
41:23
out trans fats while still
41:25
having like another relatively cheap like
41:28
functional way of accomplishing the same thing
41:30
so foods that previously had
41:32
trans fats if you're like I think I think
41:34
these fuckers are lying like like Crisco
41:37
still seems like Crisco yeah it
41:39
must still have trans fats in it like no
41:41
like now it's just using interest erified
41:43
fat yeah I thought
41:46
that was cool
41:47
you still see like I still see trans
41:49
fats on some food labels
41:51
a very small amount like 0.5
41:56
grams or something why is that is
41:58
it yogurt I'm
42:01
trying to think of things you eat. Yeah, yeah, yeah.
42:03
Dairy stuff. So there
42:06
are naturally occurring trans fats
42:10
that are mostly... Hmm,
42:13
I don't want to overstate it. I think
42:15
they entirely come from ruminants, but
42:17
it might just be mostly from ruminants. But
42:21
yeah, so in
42:23
the fermentation process, like
42:25
in the kind guts of ruminants
42:28
like cattle, sheep, goats, whatever, some
42:30
of those bacteria create some
42:33
trans fats that
42:36
the research currently suggests they're
42:38
fine, they're not... The primary
42:41
trans fat... Oh man, I'm
42:43
doing this from memory. I might be about to fuck it up.
42:46
But the primary trans fat that was industrially
42:48
produced and used in a lot of stuff was
42:50
called, I think, oleic acid,
42:53
which was basically the trans version
42:56
of the cis fat oleic
42:58
acid, which is the primary monounsaturated
43:00
fat in olive oil. And
43:03
so when you look at the epidemiological research
43:07
related to intake of
43:09
ruminant trans fats versus oleic
43:11
acid in the industrially produced trans
43:13
fats, you don't see the
43:15
same associations with heart disease
43:18
from high intake of dairy products
43:20
or beef products or whatever. The foods
43:22
that do have a little bit of those naturally occurring
43:25
trans fats in them. But
43:28
yeah, so dairy hasn't been outlawed.
43:31
The industrially produced trans
43:33
fats are what has been done
43:36
away with. But
43:38
yeah, dairy products do have some trans
43:40
fats in them, but they're biochemically
43:43
different. And
43:46
so far, the research doesn't suggest that they
43:48
have the same deleterious health effects.
43:51
That's helpful to know. So that if you see
43:53
that on a label, you're not like, oh
43:55
no. Yes. This
43:57
company is breaking the law.
43:58
Yeah. Yeah. just a dairy
44:00
product. Yeah.
44:03
Okay so those
44:05
are the nutrients that are overconsumed
44:08
and the nutrients that aren't probably
44:10
overconsumed but a lot of people think they still
44:13
are. So now let's get into
44:15
the nutrients that are often
44:18
underconsumed and just as
44:20
kind of a note to frame
44:22
this, these
44:25
are based on based on research looking
44:28
at intakes relative to typically
44:31
like EARs. So like how many
44:35
people are consuming less of a nutrient than
44:38
the average need for the nutrient in that
44:40
population. And
44:43
these are all nutrients that at least 20%
44:45
of people seem to have
44:47
insufficient intake of. Again insufficient
44:50
not deficient big difference but
44:53
also don't be
44:56
like that spooked by it because
44:59
if you refer back to the last episode due
45:01
to the way that like EARs work it
45:04
is entirely possible for 20% of
45:07
people to consume less of a nutrient
45:09
than the EAR but all individuals
45:11
to actually still be consuming as much
45:13
as they need because kind of definitionally
45:16
about half of people can
45:18
consume less than the EAR and that is sufficient
45:20
for them. So
45:23
yeah like I just wanted to make that
45:25
point like I don't
45:27
want to overmake that point because it is also
45:29
like extremely likely that
45:31
a lot of people do actually
45:34
have like insufficient intake of these
45:37
but yeah
45:39
all of which is to say these
45:41
are the nutrients that people probably could
45:43
stand to consume a bit more of but
45:46
when you hear like oh there are like
45:50
how long is this like 12-13 nutrients
45:52
that like at least 20% of people
45:54
under consume a that
45:57
doesn't mean 20% of people are deficient in
46:00
them. And B, that doesn't even mean
46:02
that 20% of people aren't consuming as
46:04
much as they need. And
46:07
it certainly doesn't mean that you are deficient
46:10
or even insufficient in all of these things,
46:12
just kind of standard caveats on the
46:14
front end. But these are the ones that
46:17
if you wanted to track your micronutrient
46:21
intake in an app, like for example,
46:23
maybe Macro Factor, who knows, they
46:26
would be good ones to keep an eye on. The
46:29
basic problem we're trying to solve here is
46:32
there are, in
46:34
apps with full robust micronutrient
46:36
reporting, there are close to 60 nutrients
46:39
that you could keep an eye on, which is a long
46:46
list. Yeah. There's no way
46:48
you can focus on all of those.
46:51
It would be a very poor use of time to closely
46:53
monitor your intake for all of these every
46:56
day. Yeah. And
46:58
so we're trying to kind of help cut it down to
47:00
a slightly shorter list of if you want
47:03
to track your micronutrients and
47:05
focus on them, these might be the ones
47:08
worth paying like a little bit closer attention
47:10
to, just to kind of help narrow
47:12
that focus. Yeah. So how
47:15
I'm going to go through these is just
47:17
to give the nutrients and
47:19
then to just give some good
47:20
sources of that nutrient.
47:23
And again, the
47:25
resource that Greg put together for the Macro
47:28
Factor Knowledge Base has all of this information
47:30
for each nutrient. So
47:33
that's a good thing to reference back
47:35
to if you don't want to be like furiously
47:38
taking notes about foods
47:40
for each of these nutrients. Let's
47:42
start with fiber. I feel like that's
47:45
one of the ones that we hear about
47:47
the most. A lot of people want to track fiber
47:49
alongside the
47:51
main macronutrients. So
47:53
actually, can I just make one more tiny note?
47:56
Of course. Okay. So
47:58
these lists of like good food. sources
48:00
for each of these nutrients. Where that came
48:02
from is in
48:05
Macro Factor, the main source
48:08
we have for foods with
48:10
full robust micronutrient reporting
48:13
is the NCCDB,
48:16
which is a research-grade
48:19
food database maintained by
48:21
the University of Minnesota,
48:23
I believe. I think that's right. Yeah, it's kind
48:27
of like the gold standard database for
48:30
foods with full micronutrient reporting. And
48:33
so where this came from is we have the
48:35
CSV file for that. And
48:39
A, don't ask me to share it with you, I will
48:41
not. We are contractually
48:44
not allowed to. But
48:46
B, what I did is essentially
48:48
just normalize
48:51
everything per hundred calories and
48:53
then just sorted the
48:56
CSV by these.
48:58
Yeah, that would be by descending. So
49:01
it's just kind of like, it's
49:03
not every food in existence, but it's most
49:06
whole foods that exist. And it's just
49:08
kind of like the foods that have
49:10
the highest density of these nutrients
49:13
per hundred calories of total intake.
49:15
So if for instance you're trying to increase
49:18
your intake of one of these, but you don't want
49:21
to just consume like a
49:23
ton of calories in the process, like for
49:26
instance, fatty beef has some
49:28
zinc in it and you can get
49:31
plenty of zinc intake from beef. But
49:33
yeah, you might have to consume like 700 calories
49:36
of beef or whatever, whereas there are foods
49:38
that are considerably
49:40
more energy
49:43
sparse that have higher densities
49:46
of this. And that's important
49:48
context to give mostly
49:50
because as you're listening to this, you
49:52
will notice that
49:54
things like nuts and seeds, which
49:57
are really good sources of a lot of of
50:00
micronutrients won't show up on
50:02
these lists. And that's just because
50:04
they're also relatively energy dense.
50:08
So yeah,
50:10
just to note the methodology,
50:13
because if there are some foods that are excluded
50:16
that you would expect, like, oh, hey, I know such
50:18
and such is a good source of vitamin E. Why was it not
50:20
on the list? It's typically
50:22
because it's just relatively energy dense.
50:25
And so this is both micronutrient
50:28
density, but also energy sparsity.
50:30
Those are the two things that are accounted
50:33
for with the methodology I used.
50:35
Yeah, that's important to note.
50:37
OK, so for fiber, per 100
50:39
calories, some
50:41
of the best sources of dietary
50:43
fiber are artichoke,
50:46
which has 20.9 grams per 100 calories, which
50:49
is a lot. That's a ton. Rhubarb
50:52
has 20 grams. Turnip
50:54
greens, 17 and 1.5. And
50:57
then just a couple more that
51:00
are below that, but above 10 grams
51:02
per 100 calories. Sauerkraut, yikama,
51:05
banana peppers, raspberries
51:08
and blackberries, lettuce,
51:09
and collard greens. Hell yeah.
51:12
So good stuff for some vegetables.
51:15
Omega 3s is the next one, in
51:17
particular, EPA and DHA. So
51:20
you mentioned
51:21
omega 3s just a minute ago when we were talking
51:23
about omega 6s.
51:24
But some good sources of omega 3s are
51:28
caviar and other fish eggs and seal
51:30
fat. Those are at the top of the list with
51:32
more than two grams of combined EPA and
51:34
DHA per 100 calories. But
51:37
that's not exactly super
51:39
actionable for a lot of people. I don't know anyone
51:42
who's like, oh yeah, I'll just consume more seal
51:44
fat, easy. So a fun thing
51:46
to note as I was putting together
51:49
the micronutrient content for the Knowledge
51:51
Base, I edited most of these out,
51:55
but for a lot of nutrients, the
51:58
best sources were... either
52:00
the meat or fat from bearded
52:03
seals or like
52:06
whale meat or whale blubber, which
52:09
like those
52:11
aren't like accessible nutrients for most people.
52:14
Like especially for like when
52:16
I was going through the individual amino acids,
52:19
dude like bearded
52:22
seal and like whale meat are
52:24
like super good sources
52:27
of most essential amino acids but I also
52:29
think they're illegal to hunt. So like I'm
52:31
not sure why they were in the database in the first
52:33
place, but yeah,
52:35
they seem to be nutrient powerhouses,
52:38
which was interesting. Yeah. Yeah.
52:41
Cod
52:41
liver oil is a classic
52:44
EPA and DHA powerhouse. But
52:46
in terms of more readily accessible
52:47
foods, it's
52:50
just a lot of seafood. So salmon, mackerel,
52:52
sardines, anchovies,
52:54
Pacific oysters, fatty
52:57
tuna are all particularly
52:59
high in EPA and DHA with 0.8 to 1.3
53:02
grams of combined EPA
53:04
and
53:06
DHA per 100 calories. Yeah.
53:09
Just most like cold water fatty fish. Yeah.
53:12
Yeah.
53:13
Okay. We're going to go through some vitamins
53:15
next. So vitamin
53:17
A, liver has by far the highest vitamin
53:20
A concentrations as we talked
53:22
a little bit about last episode Greg
53:25
went on his rant about bears, but
53:27
fatty fish, eel, yogurt and dairy
53:29
products are also great sources of vitamin
53:32
A. Vegan sources of vitamin
53:34
A are generally rich in carotenoids.
53:37
That's how you say that, right? Yeah. Awesome.
53:40
Rather than retinol. So that's like lettuces,
53:42
peppers, sweet potatoes,
53:45
spinach and other leafy greens, pumpkin
53:47
and
53:48
carrots.
53:50
Vitamin B6. Peppers,
53:53
liver, cabbage, watercress.
53:55
Watercress is one that
53:56
showed up a lot in your research. Like
53:58
that is like.
53:59
I don't like the term superfood,
54:00
but if we wanna
54:03
be calling out superfoods, it's watercress.
54:05
Yeah, I also
54:07
removed it from some of the lists for some
54:10
of the nutrients. Yeah, because
54:11
you're just like, God damn it, it's for all of them. Well,
54:13
yeah, I was
54:13
like, if people are looking through this, I don't
54:15
want them to think that I'm telling
54:17
them they need to eat this little microgreen,
54:20
like I'm some little fancy boy. You're sponsored
54:22
by Big Watercress. Yeah, but Watercress
54:24
is astoundingly nutrient
54:27
dense. But again, this
54:29
is per 100 calories and it's also very energy
54:32
sparse. Right. So that's relevant.
54:34
Yeah, because it's just a green. Yeah.
54:37
So other basics,
54:37
zucchini,
54:39
other leafy greens, okra, garlic,
54:42
tuna, cauliflower, mushrooms, turkey
54:45
and salmon.
54:47
Next up is folate. So
54:50
great sources of folate include green
54:52
leafies. Once again, get your green
54:54
leafies, spinach,
54:55
lettuce, turnip greens, arugula,
54:57
collards, mustard greens, asparagus,
55:02
yeast products,
55:04
Chinese cabbage, specifically Chinese
55:06
cabbage, kelp and
55:08
seaweed, nori.
55:10
So nori is another one that showed up a
55:12
lot for you, right? Yes. That's another
55:14
quote, superfood. Yeah, yeah,
55:17
it showed up all the time. Yeah,
55:20
I mean, it's the bottom, I
55:22
mean, seaweeds
55:25
and algaes are kind of like the
55:27
base of the marine ecosystem. We
55:31
talked about bioaccumulation in the last
55:33
episode as well and when
55:36
people say like, ah, seafood is good for
55:39
you generally, folks who aren't super informed
55:42
about nutrition, oftentimes do
55:44
generally have the idea that seafood
55:46
is good. Right. And
55:49
a lot of that just has to do with the fact that the
55:52
base of the marine ecosystem, like
55:54
it's mostly seaweeds and algaes, whereas
55:57
the base of the terrestrial ecosystem
56:00
to be like leaves and grasses. Yeah. And
56:04
when you compare the two, like seaweeds
56:06
and algaes are just like generally
56:08
more nutrient dense than like leaves and grasses
56:10
are. Yeah. But yeah, it's good stuff. Should
56:13
start
56:13
feeding all of the land mammals
56:16
or like the land animals
56:17
that we eat watercress. See what
56:19
happens. Maybe. I don't
56:22
think that would be very like economically
56:25
efficient. I know.
56:28
Maybe an experiment someone can run if they just
56:30
have like
56:31
a couple farm
56:32
animals they keep. That would be fun.
56:34
Yeah. A
56:36
couple more for folate I'll give here. Liver,
56:39
once again, okra, peppers, beets and
56:41
cauliflower. Vitamin
56:45
C. I
56:45
don't know
56:48
what type of cherries are these,
56:50
I would pronounce that
56:52
acerola or acerola.
56:54
How
56:54
do you know how that's different than
56:57
regular cherries? Is that what
56:59
regular cherries are? Let's
57:02
see. No, no, they aren't. They aren't. They
57:07
are, I think not actually even
57:09
cherries. Oh, wow. I'm glad
57:11
I asked. I could be wrong. Yes,
57:13
yes. It's a fruit similar to a cherry
57:16
that
57:16
is not botanically
57:18
speaking actually a cherry, but
57:21
they're sometimes referred to as Barbados
57:23
cherries or West Indian cherries.
57:27
Yeah, I think they're just like little fruits that
57:29
grow in what
57:35
ocean is that? The Caribbean. Like
57:38
islands in the Caribbean. But
57:40
yeah, they were the most
57:42
vitamin C dense food
57:45
in the database.
57:47
All right. So those
57:50
peppers, watercress, again,
57:53
guava, most berries high
57:56
in vitamin C, citrus
57:58
fruits, kiwis,
57:59
and cruciferous vegetables, all
58:02
great sources of vitamin C.
58:04
Vitamin D is next.
58:06
Again, this is especially important for people
58:09
with darker skin and higher latitudes,
58:11
which is something we've discussed on the
58:13
prior episodes.
58:15
Good sources of vitamin D include mushrooms,
58:17
fatty fish, dairy products,
58:20
many of which
58:20
are also fortified with vitamin D. Yeah,
58:22
like, the dairy itself isn't
58:25
particularly rich in vitamin D, but just in terms
58:27
of like, yeah, foods you would buy in the store,
58:29
most dairy products are vitamin D-enriched,
58:32
so they become good sources
58:34
of vitamin D. Nice.
58:36
Eggs, plant-based dairy
58:39
replacements that have also been
58:41
fortified with vitamin D. Same reason,
58:43
yeah. Yeah, yeah. And pork products.
58:46
Most food sources of vitamin D are
58:48
animal products, so many
58:50
vegans, especially vegans who
58:52
don't consume a lot of mushrooms,
58:53
benefit from vitamin D supplementation.
58:56
Yeah, mushrooms also come
58:58
in clutch. Like, you've been calling some stuff
59:01
out as we go along.
59:04
But yeah, like, mushrooms are
59:07
full of a lot of just like, weird nutrients that
59:09
people often don't think about. And
59:12
particularly if you don't consume animal products,
59:16
mushrooms tend to have
59:18
a lot of the stuff that might be more
59:21
challenging to consume in a
59:23
vegan diet.
59:25
Mushrooms are great.
59:26
If you're vegan and you're not eating mushrooms, that's
59:28
sad. Or if you're an omnivore
59:30
and you're not eating mushrooms. Also sad. They're delicious. Yeah.
59:32
And so versatile.
59:34
And another
59:35
thing I'll add, if you're not a good cook,
59:38
mushrooms are a great thing to cook
59:40
to kind of get your feet wet, because
59:43
it's so hard to fuck up mushrooms. Because
59:45
like, with
59:48
animal products, for instance, like meat, if
59:50
you overcook it, it just like, gets really dry
59:53
and it's disgusting. Vegetables,
59:55
you overcook them, they get like, really mushy.
59:58
Also kind of disgusting. Mushrooms
1:00:01
since like like due
1:00:03
to the way that like their protein structure
1:00:05
is If
1:00:07
you cooked them for like days eventually
1:00:10
it would break down and they'd go mushy But
1:00:14
it's very hard to overcook them and
1:00:16
dry them out like meat and it's it's
1:00:18
also like tremendously difficult
1:00:20
to overcook them and make them go mushy like
1:00:23
they They just have like a very robust
1:00:25
protein structure that is extremely
1:00:28
resilient to undercooking
1:00:30
overcooking whatever So yeah,
1:00:32
like they're they're a good food to like just
1:00:35
practice cooking Because
1:00:37
you have you have so much leeway like
1:00:39
it's so hard to fuck up mushrooms Yeah,
1:00:42
I feel like they're really good at absorbing flavor too,
1:00:44
which is another reason they would be good to practice
1:00:46
cooking Yeah, like they're little sponges. Yeah,
1:00:48
see how flavor combinations were. Yeah
1:00:51
Okay, next one
1:00:53
is vitamin E though.
1:00:56
Greg says he's not totally sold on that one So we're
1:00:58
gonna kick it over to him in just a second But some
1:01:00
good sources of vitamin E are
1:01:02
nuts seeds peppers green
1:01:05
leaf green leafy vegetables tomatoes
1:01:07
and wheat germ
1:01:09
Many oils are also fortified with
1:01:11
vitamin E to prevent degradation
1:01:13
during cooking. Yes. So
1:01:16
like you mentioned I am skeptical
1:01:18
about vitamin E Thank
1:01:21
you. Actually to one of the
1:01:23
macro factor developers Corey for bringing
1:01:26
this to my attention because
1:01:28
when Like when when
1:01:30
he was working on the micronutrient features
1:01:32
and macro factor and he started
1:01:35
monitoring his intake more closely He
1:01:37
realized that he was like
1:01:40
most people Under consuming
1:01:42
vitamin E like given the the
1:01:45
intake targets that public health bodies proposed
1:01:48
for vitamin E and he also
1:01:50
looked around he's like It seemed
1:01:52
like none of the foods I or most
1:01:55
people eat are that rich
1:01:57
in vitamin E Like the things you
1:01:59
listed here like none nuts, seeds, peppers, green leafies,
1:02:01
whatever, they do have some vitamin E
1:02:03
in them, but the fact that
1:02:05
nuts and seeds are at the top, in
1:02:08
spite of being quite energy dense, should
1:02:10
suggest that it's pretty difficult to consume
1:02:13
a lot of vitamin E in your diet without
1:02:15
just eating 1,400 calories of nuts a
1:02:17
day, which most people aren't doing. So
1:02:21
it's like, hey, what gives? And
1:02:24
so, yeah, he asked me
1:02:26
about that. I'm like, oh, that's an interesting
1:02:28
question. I'll look into it more. And
1:02:31
I came across a publication from
1:02:33
the EFSA, which is
1:02:35
like the European body that
1:02:38
sets their micronutrient targets, the European
1:02:40
Food and Safety Authority. And
1:02:44
here is a quote
1:02:47
from their publication where
1:02:49
they set
1:02:52
their AIs for vitamin E. So
1:02:56
here's the quote. The classification of
1:02:58
vitamin E as an essential nutrient is
1:03:00
based on animal studies and primary and secondary
1:03:03
alpha tocopherol deficiency in humans.
1:03:05
The need for alpha tocopherol, which is like the
1:03:08
primary source, like this is not
1:03:10
from the quote anymore. Alpha tocopherol
1:03:12
is kind of like the scientific name for,
1:03:16
there are like multiple chemical
1:03:18
compounds that fall under the umbrella of vitamin
1:03:21
E, but like alpha tocopherol is like the
1:03:23
main one. Okay. Just so people
1:03:25
listening will know what they're talking about. The
1:03:27
need for alpha tocopherol in order to
1:03:29
prevent fetal reabsorption in pregnant
1:03:32
rats fed large containing diets
1:03:34
is the origin of the discovery of the vitamin.
1:03:37
The chemical name tocopherol derives
1:03:40
from its essentiality for
1:03:43
normal reproduction in animals, even
1:03:46
though the essentiality for this function has
1:03:48
never been demonstrated in humans. Symptomatic
1:03:51
alpha tocopherol deficiency
1:03:53
in individuals without any disease and who
1:03:55
consume diets low in alpha tocopherol
1:03:58
has never been reported.
1:03:59
So here's my
1:04:02
very hot, here's maybe my hottest
1:04:04
micronutrient cake. Oh wow. I kind
1:04:06
of think that vitamin E should be considered a
1:04:08
conditionally essential nutrient. Yeah. So
1:04:11
yeah, like basically to break that
1:04:14
down and just provide a little more context, like
1:04:17
it is definitely like something
1:04:19
you need. So like people
1:04:21
who have like genetic
1:04:23
conditions that create
1:04:26
like errors in vitamin E metabolism or
1:04:28
people who have like intestinal disorders
1:04:32
or like conditions that inhibit
1:04:34
or completely prevent the absorption of vitamin
1:04:36
E do suffer health consequences
1:04:39
as a result of like
1:04:42
not having enough vitamin E in their
1:04:44
body. But for people who are
1:04:46
generally healthy, don't have those genetic conditions
1:04:49
that interfere with vitamin E metabolism, don't
1:04:51
have any like a gastrointestinal issues
1:04:54
that prevent the absorption of vitamin E. Even
1:04:58
when people like consume extremely
1:05:01
low amounts of vitamin E in their diet,
1:05:03
like they seem fine.
1:05:07
So yeah, it seems like most people don't need to
1:05:09
worry about vitamin E intake. In
1:05:12
spite of the fact that like as alluded
1:05:14
to at the start of the story, the like
1:05:17
AI, like
1:05:19
the adequate intake value for vitamin
1:05:21
E is quite high.
1:05:24
So like I'm not totally sure where that disconnect
1:05:27
comes from,
1:05:28
but
1:05:29
basically like vitamin E is on the
1:05:31
list of nutrients that according
1:05:34
to the intake targets that public health bodies propose,
1:05:36
it seems like the vast majority of people under
1:05:38
consume. But I'm actually not so
1:05:41
sure that most or like hardly
1:05:43
anyone actually under consumes it. Cause like,
1:05:46
It sounds
1:05:46
like it might not even be essential. No,
1:05:49
like
1:05:49
it is essential. Like if you fed
1:05:51
someone a completely vitamin E
1:05:54
deficient diet, like no vitamin
1:05:56
E whatsoever, like bad things would happen. But
1:05:58
like there's a little bit of vitamin E. and like a lot
1:06:01
of stuff. It seems like if you consume a
1:06:03
little bit of vitamin E, like you're fine.
1:06:06
Anyway, so yeah, like it
1:06:09
is on this list because I applied the same methodology
1:06:11
to everything. Like there's research
1:06:14
on like rates of insufficient
1:06:16
consumption of various essential nutrients
1:06:18
and like vitamin E shows up on those lists, but
1:06:21
I just wanted to voice my skepticism
1:06:23
about whether it should be on that
1:06:25
list and whether it should even be considered like
1:06:27
an essential nutrient for everyone in the first place.
1:06:30
Most people don't need to worry about that. That's
1:06:32
what I was saying when I said not essential.
1:06:34
Yeah, yeah, yeah. Okay,
1:06:37
let's move on to the next vitamin, which is vitamin
1:06:41
K, sometimes referred to as K1 and K2. Those
1:06:45
are the two types. They have similar
1:06:47
biological functions. Green leafy
1:06:49
vegetables are by far the
1:06:52
best source of vitamin
1:06:54
K1 and some
1:06:56
fermented foods, most notably natto,
1:06:59
which is a Japanese fermented soybean
1:07:01
product. Those
1:07:04
fermented
1:07:04
foods are the best sources of vitamin K2.
1:07:07
Next up is choline. So
1:07:10
egg yolks, fish, liver,
1:07:13
and shellfish are all particularly
1:07:15
good sources of choline. Legumes
1:07:18
in general and soybeans in particular
1:07:20
are good vegan sources of choline.
1:07:24
So those are our vitamins.
1:07:26
And now we are on to minerals. First
1:07:29
up is magnesium. Good sources of magnesium
1:07:31
include green leafy vegetables like chard
1:07:33
and spinach, rhubarb, okra,
1:07:36
soy products, whole grain products, and
1:07:39
many nuts and
1:07:39
seeds.
1:07:41
Potassium is next. So
1:07:44
once again, green leafy vegetables, eat
1:07:46
your green leafies. Mushrooms, root
1:07:48
vegetables like potatoes and peeps. Tomatoes,
1:07:52
various squashes, including pumpkin,
1:07:54
summer squash, acorn squash, and zucchini.
1:07:57
Asparagus, peppers, okra,
1:07:59
cruciferous vegetables, beans,
1:08:02
and most fruits
1:08:03
are great sources of potassium. That's a lot of
1:08:05
things for potassium. Yeah, like it's basically
1:08:08
most plants. Yeah, just like most plant products.
1:08:11
Yeah.
1:08:11
With the exception
1:08:13
of nuts, seeds, and grains, most plant
1:08:15
products are pretty good sources of potassium.
1:08:19
And last up is zinc.
1:08:22
So shellfish, mushrooms, liver,
1:08:25
dried seaweed once again, nori, beef, green
1:08:30
leafy vegetables, whole grain products,
1:08:33
particularly the bran, and some
1:08:36
seeds, all good sources of zinc.
1:08:38
Absolutely.
1:08:39
And so that was our second category
1:08:42
of things that are often under-consumed.
1:08:46
Now we're moving on to our third. The
1:08:48
last category is vegans,
1:08:51
the nutrients that vegans in particular
1:08:53
may want to pay close attention to. Yes.
1:08:56
So just at the start of this, I
1:08:58
will acknowledge that we
1:09:00
on this podcast are both omnivores. And
1:09:03
I know a lot of vegans
1:09:06
are sensitive to omnivores
1:09:10
who are trying
1:09:12
to be well-meaning, lecturing
1:09:14
them about, like, don't go
1:09:16
vegan, like, it's so hard to consume
1:09:18
a nutritionally complete diet. Where's
1:09:21
the protein coming from? Blah, blah, blah, whatever.
1:09:25
We're not on that tip. Like,
1:09:28
we have absolutely no
1:09:30
issue with people being vegan, and
1:09:32
certainly not trying to harangue anyone
1:09:35
about that. But
1:09:37
it is also true that
1:09:39
certain nutrients do predominantly
1:09:43
come from animal products. And
1:09:45
so, like, yeah, it's absolutely
1:09:48
possible to consume
1:09:50
a very healthy and nutritionally complete
1:09:53
vegan diet. But, like, certain nutrients, it
1:09:55
might take a little bit more planning. And
1:09:58
when you look at the research... on
1:10:02
rates of insufficient intake for particular
1:10:04
nutrients. There are some where rates of insufficient
1:10:06
intake are quite a bit higher for
1:10:08
vegans than for omnivores. So
1:10:11
yeah, that's what we're gonna talk about. So
1:10:14
the first is EPA
1:10:17
and DHA, like the two kind of most
1:10:19
important omega-3s. Because
1:10:22
again, like most of the best sources of
1:10:24
EPA and DHA are like
1:10:27
cold water, fatty fish. But
1:10:30
if you're not going to consume them and
1:10:33
you also don't want to consume
1:10:35
fish oil because you're very strict
1:10:37
about your veganism, totally understandable,
1:10:40
it's probably not a bad idea to
1:10:42
look into an algae oil supplement.
1:10:45
Again, going back to the idea of bioaccumulation,
1:10:48
most of the omega-3s that would show up in a
1:10:50
salmon in the first place did start
1:10:52
in an algae. So
1:10:54
yeah, it's I think a little bit less
1:10:57
efficient to produce algae
1:10:59
oil, and therefore it's a little bit more expensive
1:11:02
than fish oil would be. It contains
1:11:04
the same EPA and DHA, probably
1:11:07
a decent thing to look into. The
1:11:12
next one, which I'm sure
1:11:14
some eyes will be rolling when I mention this, I'm
1:11:16
not going to harp on it, is
1:11:19
maybe some individual essential
1:11:21
amino acids. Although I will note,
1:11:25
the vast majority of the time, this
1:11:27
is not something most vegans
1:11:29
need to worry about. If you
1:11:31
consume a varied diet or if you
1:11:34
consume plant-based
1:11:36
products that do have
1:11:39
a full essential amino
1:11:41
acid profile, so
1:11:43
if you consume soy, if you consume
1:11:46
plenty of mushrooms,
1:11:48
although I know they're not a plant, fungi,
1:11:51
different kingdom of life, but yeah,
1:11:53
fungi and soy, they have the full
1:11:55
complement of essential amino acids. You
1:11:57
consume some of those, like you're definitely good. Or
1:12:00
if you don't but you consume a generally varied
1:12:02
diet, you will also be good. But
1:12:05
like if you're kind of lazy
1:12:08
about your intake
1:12:10
and like don't have that varied of a diet,
1:12:14
you might be under
1:12:16
consuming some essential amino acids. So like
1:12:19
for instance, if you have an
1:12:21
extremely grain-based diet,
1:12:24
you might wanna keep an eye out for lysine
1:12:26
and maybe like make a point of
1:12:29
consuming some vegan protein sources
1:12:31
that have some lysine in them. Or
1:12:34
if you just have like a
1:12:36
very legume rich diet
1:12:39
and not much else, you
1:12:41
might be like you might have difficulty
1:12:44
consuming enough methionine. But
1:12:46
like that's why the combination of rice
1:12:48
and beans is like the classic poverty
1:12:50
food because rice, like it's
1:12:52
a cereal grain, beans,
1:12:55
legumes obviously, legumes,
1:12:58
not much methionine, plenty of lysine, vice
1:13:00
versa for rice. So
1:13:02
yeah, like if you consume some soy products
1:13:05
or mushrooms or just like don't
1:13:07
only eat like one food, like you probably
1:13:09
don't need to worry about it, but like that is technically
1:13:12
a higher risk with a vegan diet than an
1:13:14
omnivorous diet. Moving
1:13:17
on to vitamins, really the
1:13:20
biggest one to pay mine to is vitamin
1:13:22
B12. Like we
1:13:24
mentioned in the last episode, virtually
1:13:28
all of the B12 that's out there comes from
1:13:30
ruminants. Like
1:13:33
the bacteria in the hindgut of
1:13:35
ruminants are really the only
1:13:37
things that at scale produce
1:13:41
vitamin B12. Essentially
1:13:45
vitamin B12 is just kind of like a normal vitamin
1:13:47
structure with like some cobalt
1:13:49
in the mix. And there just aren't that many
1:13:52
like enzymes on this earth
1:13:54
that can fix cobalt in that vitamin
1:13:56
structure to make vitamin B12. to
1:14:00
the stuff that does do it, like lives
1:14:02
in the guts of cows or like sheep
1:14:04
or goats or whatever. So
1:14:06
yeah, like may not be a terrible idea
1:14:08
to look at a vegan B12 supplement. And
1:14:12
then there are a handful of minerals
1:14:15
that it might be worth paying a bit of attention
1:14:18
to. Those would be calcium,
1:14:21
iron, zinc, and selenium.
1:14:24
And calcium, iron, and zinc are kind of grouped together
1:14:27
with calcium. It's
1:14:32
mostly a matter of the fact that like, there
1:14:34
aren't that many plant-based products
1:14:37
that are rich in calcium and most of
1:14:39
the ones that are. Like
1:14:42
most calcium in the human diet comes from
1:14:44
dairy products. And
1:14:46
most of the plant-based foods that are rich
1:14:48
in calcium are also relatively rich
1:14:51
in oxalates and phytates, which inhibit
1:14:54
the absorption of calcium. Similar
1:14:58
with iron as well. So
1:15:00
most iron-rich plant-based
1:15:02
foods are also rich in oxalates and phytates.
1:15:05
Same thing, like chelates the iron, like
1:15:08
inhibits the absorption. And
1:15:11
just like plant,
1:15:14
like heme-bound iron tends to
1:15:16
be more like orally bioavailable.
1:15:20
And similar with zinc as
1:15:22
well. The
1:15:24
other mineral that's kind of like
1:15:27
affected by the same set
1:15:30
of circumstances where foods
1:15:32
that are rich in it also tend to be rich in phytates
1:15:34
and oxalates is magnesium. But
1:15:37
like vegans don't need to worry about magnesium
1:15:40
and take more than anyone else does.
1:15:42
And the main reason for that is like, basically
1:15:44
every magnesium-rich food is like a plant
1:15:47
food in the first place. Right. But
1:15:50
yeah, so calcium,
1:15:53
iron, zinc might be worth paying attention
1:15:55
to, like a lot of the richest
1:15:58
sources of those minerals. are
1:16:00
animal products and a lot of the plant
1:16:02
products like the nutrients themselves
1:16:05
might be slightly less bioavailable.
1:16:08
And then the last one, for
1:16:10
reasons that I'm totally not, I'm not
1:16:12
totally sure of is selenium. Like most
1:16:15
good sources of selenium are also plant
1:16:17
products but research
1:16:20
on just kind of like blood biomarkers
1:16:24
of micronutrient status tends to find
1:16:26
that vegans have like lower selenium levels than
1:16:29
omnivores do. So
1:16:31
yeah, those are the ones to look out for.
1:16:35
But with most of them, like
1:16:38
mushrooms and soy products
1:16:40
help
1:16:44
a lot and for selenium specifically,
1:16:47
just like eat a couple of Brazil nuts from time
1:16:49
to time, most nuts are very poor
1:16:51
in selenium. Brazil nuts are
1:16:54
like extremely rich in selenium, not
1:16:56
totally sure why, but do you know
1:16:58
what Brazil nuts are, Linz? The big ones.
1:17:01
Yes, I love Brazil nuts.
1:17:03
They're pretty good. I always used to pick those
1:17:05
out of like the nut mixes that my parents would
1:17:07
get. They're good. Yeah,
1:17:10
did they have a shell on or shell off?
1:17:13
Off. Okay, so we
1:17:15
got the shell on nut mix around
1:17:17
like Christmas time every year. Oh my gosh, that's
1:17:20
so much work. Well, so
1:17:24
like we started getting them and I was like a
1:17:26
little guy, like little, little. And
1:17:28
so like I remember, so
1:17:31
I've always been kind of like weirdly
1:17:34
obsessed with like testing how strong
1:17:36
I was. Like it's not a mistake
1:17:38
that I found powerlifting. And so
1:17:40
like we have these little nut crackers and
1:17:43
every year I was like interested to see
1:17:46
like, ooh, can I crack more nuts now than
1:17:48
I could last year? Oh my gosh. Cause like
1:17:50
the easiest ones were like walnuts. Like they're big,
1:17:53
but like they have relatively thin shells. There's
1:17:55
a lot of air in them. So like the crack
1:17:57
walnuts pretty easy, but then like almonds
1:17:59
hurt. more difficult and like Brazil nuts
1:18:02
were kind of my white whale. No. Because
1:18:05
they had the thickest shells that were the hardest to crack. That
1:18:07
makes sense. And I remember, and
1:18:10
I also kind of had it in my mind as a little guy
1:18:12
that like the bigger nuts
1:18:15
were just like more annoying. I think just because
1:18:17
like walnuts, like
1:18:20
they were the biggest other than the Brazil nuts.
1:18:22
Like they were comparable in size. But
1:18:24
like instead of just having like a single
1:18:27
thing in there that you could like grab and like
1:18:30
most of the stuff inside was edible. Like
1:18:34
almonds for instance, like smaller but like you crack
1:18:36
it and the interior is just the almond.
1:18:39
Like the walnut
1:18:41
was kind of like, you know, there
1:18:43
was like really bitter kind of like pith
1:18:46
like holding it together and like the nut
1:18:48
was in like multiple parts. I was like, it's kind
1:18:50
of annoying. Like I assumed the Brazil
1:18:53
nut would be as well. But then when I cracked
1:18:55
it and it was just like a big fucking
1:18:57
guy that was like fully
1:19:01
like filling out the shells. I
1:19:03
was so happy. Yeah. And
1:19:05
it was delicious. And so like they are to this day
1:19:07
my favorite nut. How
1:19:09
old were you when you could crack open
1:19:12
the Brazil nut? I don't remember. I
1:19:14
don't remember. Like so pretty small probably.
1:19:17
Yeah. Yeah. Yeah.
1:19:20
I mean, it wasn't like 14. I was probably five
1:19:22
or six. But
1:19:25
yeah, yeah, it was fun.
1:19:26
A lot of snack for less effort
1:19:28
once you can do it. And a
1:19:30
very good source of selenium. Of
1:19:32
course, that was really important too as a five year old.
1:19:34
Yes. No, I had no idea. It
1:19:39
will shock you to work. Okay, let's
1:19:41
move on. So just
1:19:44
kind of zooming out, we provided
1:19:47
this list. But yeah,
1:19:49
if you're going to track your micronutrient intake,
1:19:51
just kind of use this list as a starting point
1:19:55
because what you
1:19:58
as an individual need to pay attention to. attention to will
1:20:00
depend like pretty heavily on your own dietary
1:20:03
patterns. So like those are the
1:20:05
nutrients that like on average
1:20:07
tend to be under consumed in like
1:20:10
more developed nations. But you
1:20:12
know, your your diet may not closely
1:20:15
resemble the average diet of wherever you live.
1:20:19
And so like, for example, if you don't eat a particularly
1:20:22
varied diet, like if you're listening to this, and
1:20:24
you're like an old school bodybuilder, and your
1:20:26
diet is 90% just like chicken breast
1:20:28
rice and broccoli, there
1:20:31
might be a lot of micronutrients that you're consuming.
1:20:34
Yeah. Like, yeah,
1:20:36
they're leaving out a lot of food. Yeah, like
1:20:38
the macros of your diet are good. But like, there
1:20:40
might be some pretty big gaps there. Or
1:20:43
just like if you consume a lot of like quote
1:20:45
unquote, empty calories, like a lot
1:20:47
of soda, a lot of like fried food,
1:20:50
whatever, the list might
1:20:52
be considerably longer for you or
1:20:54
just if you have food choices that
1:20:56
are like way different than the average person,
1:20:58
your list might be the same length but different.
1:21:02
Or like if you tend to consume
1:21:04
a lot of like minimally
1:21:07
processed whole foods ingredients, like
1:21:09
plenty of mushrooms, plenty of fruits, plenty of
1:21:11
vegetables, you might be consuming like
1:21:14
there's a very good chance you're consuming sufficient
1:21:16
amounts of like basically every micronutrient
1:21:18
and there might be like one or two that you
1:21:20
might want to keep an eye on. All
1:21:23
of which is to say just kind of use this list
1:21:25
as a starting point. But what we wanted to do
1:21:27
with it is
1:21:30
of like the 50 or 60 individual
1:21:32
nutrients you could track in an app like Macro
1:21:34
Factor, you don't
1:21:37
want to pay attention to all of them. So like this kind
1:21:39
of is the initial process of
1:21:42
helping you narrow that list down a little bit.
1:21:45
Yeah,
1:21:46
I think that's it for
1:21:48
this part of the episode.
1:21:51
So let's shift gears.
1:21:56

1:23:18
So this whole series
1:23:22
has been about micronutrients,
1:23:24
and to put a bow on it, I want
1:23:26
to take a step back and recommend not
1:23:29
getting too fixated on micronutrients
1:23:31
and to not fall for the trap of
1:23:34
what I like to term micronutrient reductionism.
1:23:38
So like humans have a tendency
1:23:41
to like numerical targets, or
1:23:43
maybe that's not humans, maybe it's just me
1:23:45
and people that listen to this podcast, but
1:23:48
yeah like I like numerical targets
1:23:50
and it can be easy to treat something
1:23:53
that you can quantify numerically as
1:23:56
a as like the
1:23:58
outcome that matters. to you instead of
1:24:01
a proxy for the actual outcome that
1:24:03
matters to you. In this case,
1:24:05
I think that there's a tendency
1:24:07
for people to want to consume a healthy diet.
1:24:10
They're like, okay, well, how can I quantify
1:24:13
the healthiness of my diet? It's
1:24:16
hard to put a number on that, but it is easy
1:24:18
to put numbers on how much of each
1:24:20
micronutrient am I consuming. You
1:24:24
operationally define healthy diet
1:24:26
as a diet that contains the recommended
1:24:29
amount of all essential nutrients. In
1:24:32
a vacuum, that's fine,
1:24:34
but
1:24:37
if you wanted to
1:24:39
approach it from the perspective of, I
1:24:41
want to eat enough micronutrients and I'm going to do
1:24:44
it
1:24:46
by attempting to conform to what's
1:24:49
generally recommended as healthy dietary
1:24:52
practices, eating a diverse
1:24:55
array of minimally processed foods to
1:24:57
help you meet those nutrient targets, I
1:24:59
think you would have a very hard time not
1:25:02
consuming a relatively healthy diet, but
1:25:06
it can become problematic when the targets
1:25:09
themselves become like
1:25:12
you start treating them as your actual
1:25:14
goal and metric for success instead of
1:25:16
just a proxy for what you're actually pursuing.
1:25:19
In other words, you might run into problems when
1:25:21
a proxy for your goal replaces
1:25:24
the actual goal itself. In other words, the proxy
1:25:26
is meeting your micronutrient targets and
1:25:29
the actual goal is eating a diet
1:25:31
that generally promotes good health. Yeah,
1:25:33
that makes a lot of sense. We
1:25:37
see this in so many other domains.
1:25:40
Whenever you and I were talking about this before
1:25:42
the episode, it reminds
1:25:46
us of people learning
1:25:48
that training volume is important for
1:25:50
hypertrophy and then fixating
1:25:53
on getting as much volume and
1:25:56
that being the outcome rather than
1:25:58
focusing on the outcome
1:26:00
of the training volume itself. Or
1:26:03
like in a business, getting fixated
1:26:06
on a proxy measure of success like your
1:26:09
Instagram following, your TikTok following,
1:26:11
and that leading you to do things
1:26:14
like buying followers or like putting
1:26:17
out content you're not proud of to optimize
1:26:19
for follower count rather
1:26:21
than actual business growth. Like
1:26:23
just kind of
1:26:26
forgetting the forest and
1:26:28
focusing on the trees, forgetting
1:26:31
what
1:26:31
outcome actually mattered to you at the beginning
1:26:33
and kind of fixating on a proxy. 100%. So
1:26:38
yeah, like when you go
1:26:41
down this road and you start and
1:26:43
your focus shifts excessively towards
1:26:45
numerical targets, you might
1:26:47
start making choices that are optimized
1:26:50
for the pursuit of those targets instead of
1:26:52
the pursuit of the actual goal. So
1:26:54
like for instance, you
1:26:57
might learn and like this is true,
1:27:00
that your body can like absorb
1:27:02
and utilize pre-formed vitamin A
1:27:04
like retinol more efficiently
1:27:07
than it can carotenoids, which are
1:27:09
like pro vitamin A like you
1:27:12
absorb them and your body kind of does
1:27:14
some metabolic stuff and converts them to vitamin A
1:27:16
but like that's slightly less efficient.
1:27:20
And so you might like quote unquote realize
1:27:22
that hey, like vitamin A that's
1:27:24
a fat soluble vitamin, you don't need to consume
1:27:27
it every day. There's a shitload
1:27:29
of pre-formed vitamin A in liver, just
1:27:31
eat one serving of liver per week.
1:27:34
And now you don't need to worry about vitamin A intake.
1:27:38
You don't need to worry about consuming anything with
1:27:40
carotenoids like you're good, your vitamin
1:27:42
A is taken care of. And so
1:27:44
you're like, okay, like I don't need to eat like carotenoid
1:27:47
rich fruits or vegetables anymore, which
1:27:50
in terms of like vitamin A intake
1:27:53
in a vacuum, you're 100% right. But
1:27:56
there are like plenty
1:27:58
of health benefits and just like other beneficial
1:28:00
bioactive chemicals in carotenoid
1:28:03
rich fruits and vegetables that aren't
1:28:05
present in liver. And so, you know,
1:28:07
you're ultimately reaching your target,
1:28:09
but you're moving further away from theoretically
1:28:12
what your goal is, which is trying to eat a healthy
1:28:14
diet.
1:28:15
Or like
1:28:17
for a more extreme
1:28:19
example of the same concept. And
1:28:22
this is related to a question that we were asked
1:28:24
a bunch in the groups as we were like putting
1:28:27
out the series, and we're
1:28:29
going to address it in the
1:28:31
context of like a Q&A question at the end of this
1:28:33
episode. But multivitamins,
1:28:36
like you might start
1:28:39
by thinking, hey, I'm going to
1:28:41
try to eat a healthy diet that has all
1:28:43
of my micronutrients, but then you start getting more
1:28:46
like hyper fixated on the micronutrients
1:28:48
instead of the healthy diet. And then you realize like,
1:28:51
wait a second, I could just have a
1:28:53
diet of like french fries and chicken tendies
1:28:56
and just like take a multivitamin every
1:28:58
day. I'm good. Like
1:29:00
the exact example I was going to give. Yeah,
1:29:02
like it starts getting warped in that direction.
1:29:05
Like once you start interpreting
1:29:07
healthy diet as just micronutrient complete
1:29:09
diet, you can eat fucking anything and just take
1:29:11
a multivitamin and like you're
1:29:14
meeting that goal.
1:29:16
But
1:29:17
like, and
1:29:19
we'll talk about this more later, the
1:29:22
research on multivitamins
1:29:24
isn't like all that promising. And
1:29:28
also kind of going back to the carotenoid
1:29:30
liver example, there's
1:29:33
a ton of healthy stuff and like fruits and vegetables
1:29:35
that you're not going to get from tendies and fries, that
1:29:38
you would just be missing out on if you went that
1:29:41
route. And so like just to give two
1:29:43
examples, because like it's easy
1:29:45
to say like, yeah, there's a lot of healthy stuff in
1:29:47
fruits and vegetables other than the micronutrients. But
1:29:51
like, I think people tend to like concrete
1:29:53
examples. So I'll provide a couple concrete
1:29:55
examples. So starting
1:29:58
with, yeah.
1:29:59
Yeah,
1:30:00
more so fruits, but there's some of these
1:30:02
in vegetables as well. Polyphenols.
1:30:06
Polyphenols fucking rock. I'll
1:30:08
link a research review in the show
1:30:10
notes for anyone who wants to check it out. It's
1:30:14
free full text, easy to read.
1:30:18
Polyphenols have positive effects
1:30:21
on reducing your risk of neurodegenerative
1:30:23
disease, reducing inflammation
1:30:25
levels, reducing cancer risk,
1:30:29
helping improve cardiovascular health, type
1:30:32
two diabetes risk and management. They
1:30:38
might also reduce obesity risk,
1:30:41
both from helping your body
1:30:43
partition nutrients better and also affecting
1:30:46
hunger in a positive way. They
1:30:49
do a lot of good shit through a very
1:30:52
surprisingly wide array of mechanisms.
1:30:57
They're not micronutrients. They're
1:30:59
good for you. Going back to the first episode
1:31:01
in this series, what
1:31:05
micronutrients are, essential nutrients are
1:31:07
things that if you
1:31:09
don't consume them, you will die
1:31:12
or suffer very deleterious health consequences.
1:31:16
Polyphenols aren't essential nutrients. If you never
1:31:18
ate a blueberry in your life, you'd be fucking fine.
1:31:21
Most people throughout human history never ate a blueberry,
1:31:23
believe it or not. It's
1:31:27
still good for you. You know what I mean?
1:31:30
I like that you're mentioning this as
1:31:32
well because whenever we are going
1:31:35
through the list of micronutrients
1:31:39
that people might want to pay attention to, a lot
1:31:41
of those were just vegetables. There
1:31:43
weren't as many fruits and berries and stuff
1:31:45
in there. Whenever
1:31:48
you and I were first talking about this, that
1:31:50
was surprising to me because I always thought,
1:31:53
oh, blackberries and raspberries and stuff,
1:31:55
that's super good for you.
1:31:59
They do
1:32:00
have micronutrients in them, but it's also like,
1:32:02
it's for this reason that they are
1:32:05
really, really beneficial. Yeah. And
1:32:07
if you were just focusing on, oh, what's
1:32:09
the most bang for my buck I can get with
1:32:12
micronutrient related foods, like
1:32:14
you might skip out on some of these benefits. Yeah,
1:32:17
for sure. Like
1:32:19
just fruits in general, but like berries
1:32:22
and like cherries in particular,
1:32:26
do have like a ton of beneficial
1:32:28
bioactive compounds that aren't like
1:32:30
classified as micronutrients. And
1:32:33
so yeah, if you were approaching
1:32:35
your diet from the very narrow focus
1:32:37
of like only just trying to maximize
1:32:40
micronutrient intake, even if you're not going
1:32:42
the multivitamin route, like even if you are
1:32:45
trying to go like the whole
1:32:47
minimally processed food route, like
1:32:51
there wouldn't be a great reason to
1:32:53
consume berries because like they
1:32:56
tend to be like decent sources of
1:32:58
like vitamin K and manganese.
1:33:02
And they tend to be like decent sources of vitamin C,
1:33:04
but like
1:33:05
not
1:33:06
so much compared to other foods. Like
1:33:09
there are like way, there are foods that are way
1:33:11
richer than like vitamin K, manganese and vitamin
1:33:13
C. So yeah, like
1:33:15
you'd look at them and be like, yeah, that's
1:33:18
not a micronutrient powerhouse. Like why
1:33:20
bother? But like it's the
1:33:22
other stuff in them that like aren't
1:33:25
micronutrients. They tend to make them like particularly
1:33:27
beneficial. Now
1:33:30
moving over to vegetables, like
1:33:34
oftentimes like some of the
1:33:36
more like
1:33:39
the vegetables that people tend to make like the most health
1:33:41
claims about like that people
1:33:44
tend to term like super foods, which yeah,
1:33:46
I don't know. That's all everyone ever
1:33:49
talks about. Yeah, like I don't really
1:33:51
like that term, but like I see where people are
1:33:53
coming from. And like cruciferous
1:33:55
vegetables are the ones that people tend to
1:33:57
bring up the most. So you know, Brock.
1:34:00
broccoli, cauliflower, kale, cabbage,
1:34:02
Brussels sprouts, etc. Lots
1:34:05
of brassicas. Yeah. Oh,
1:34:08
man. Is that a...
1:34:10
Is that a...
1:34:11
That's a circle square
1:34:13
situation, but I forget which one. It's
1:34:16
either all brassicas are cruciferous vegetables,
1:34:18
but not all cruciferous vegetables are brassicas
1:34:21
or the other way around. It's
1:34:23
the first one. It's the circle square, rectangle
1:34:25
square. Rectangle square, rectangle square. My
1:34:27
bad. Yes. Yes. So
1:34:30
all brassicas are cruciferous vegetables, but
1:34:32
not all cruciferous vegetables That's
1:34:34
right. Yeah. Both. Yes.
1:34:37
I only know that because of gardening. Yes. But
1:34:40
yeah, so they're like they're good for you
1:34:42
and they're like a little more micronutrient
1:34:45
rich than like berries and cherries
1:34:47
are. They're decent sources of vitamins
1:34:49
C and K. And
1:34:52
in particular, like the the
1:34:54
like green leafy brassicas like
1:34:57
kale, for instance, are
1:35:00
like very micronutrient rich and
1:35:03
energy sparse. But, you
1:35:05
know, stuff like as we were
1:35:07
going through the list of like good sources
1:35:10
for like a lot of those nutrients, I don't
1:35:12
think like broccoli showed up once, for instance,
1:35:14
or if it did, like maybe it only showed up once.
1:35:17
Right. Or Brussels sprouts. Or
1:35:19
Brussels sprouts. Yeah. Or
1:35:21
regular cabbage, only Chinese cabbage. Right.
1:35:24
And yeah, like they do
1:35:26
have like some micronutrients, but
1:35:29
they're like particularly beneficial
1:35:31
due to a class of compounds called isothiocyanates,
1:35:37
which are in like I'll
1:35:39
link some some research related to this as
1:35:41
well. But like they have like antioxidant,
1:35:43
anti-inflammatory, anti-cancer
1:35:46
and antibacterial properties.
1:35:48
All the antes you want. Yeah. And
1:35:52
you know, like their their benefits are born out both
1:35:55
from like epidemiological
1:35:58
research, but also like mechanistic style. Like
1:36:01
it doesn't seem to be like fully just a correlation
1:36:03
causation issue But
1:36:06
yeah, like if if you were being
1:36:08
like really really intentional about Micronutrient
1:36:11
intake Yeah, you might still
1:36:14
end up eating some cruciferous vegetables But
1:36:16
like not the full range of them because
1:36:18
like only a handful of them would show up on
1:36:20
kind of a list of micronutrient Powerhouses,
1:36:23
but they all have like plenty of isothiocyanates
1:36:26
and like they're all good for you for reasons
1:36:29
beyond just their micronutrient content
1:36:34
So, yeah like
1:36:35
The the basic takeaway
1:36:37
here is that you can't reduce the overall like quote-unquote
1:36:40
healthiness of a diet to its micronutrient
1:36:43
content If you could again
1:36:45
like a multivitamin would be a wonder drug,
1:36:47
but it's not like
1:36:50
I think it's I think it's helpful to look at
1:36:52
it through kind of the
1:36:55
Yeah
1:36:57
the lens of like necessary versus
1:36:59
sufficient Like eating
1:37:01
plenty of micronutrients is necessary
1:37:03
for a healthy diet But it's not sufficient
1:37:06
for your diet to be as healthy as it could be and
1:37:09
I think that it's easy to Miss
1:37:12
that if you become like to target
1:37:14
focused.
1:37:15
I think it's easier to
1:37:17
like
1:37:19
To just focus on eating
1:37:21
a wide variety of foods
1:37:24
and not necessarily
1:37:24
like
1:37:26
Fixating on a specific micronutrient
1:37:28
target. Yeah, you know like it That's
1:37:32
also
1:37:32
a reason to do it. It's like it's just like
1:37:34
gonna be better for your mental health as
1:37:36
well as your physical health Yeah
1:37:40
Um,
1:37:41
yeah, so that's just kind of like the note that
1:37:43
I wanted to end this series on like it has
1:37:45
been about micronutrients There's a
1:37:47
lot of good stuff related to micronutrients There
1:37:49
are a lot of people who maybe like should
1:37:52
pay a little bit more attention to their micronutrient
1:37:54
intake is like if you Don't eat
1:37:57
a diverse minimally
1:37:59
processed
1:37:59
processed
1:38:01
diet, whatever. Like there's a non-trivial
1:38:04
chance that you probably could consume
1:38:06
a bit more of some micronutrients and that could
1:38:09
have some benefits for you. But like if
1:38:11
you go that route, basically what I'm saying
1:38:13
is don't miss the forest for the trees. Don't
1:38:15
reduce the idea
1:38:18
of like eating a healthy diet to just
1:38:20
a micronutrient complete diet. Like it
1:38:23
absolutely goes beyond that. So
1:38:26
yeah, like just kind of, I
1:38:29
think you can distill a lot of it
1:38:31
down to some general
1:38:33
rules or guidelines
1:38:36
that most people are probably aware of
1:38:38
already. Like eat your protein, eat
1:38:40
your fiber, don't go overboard
1:38:43
on added oils and sugars, make
1:38:45
sure you're consuming a variety of fruits and
1:38:47
vegetables, and I would also add seaweeds
1:38:50
and mushrooms in there if you would like. And
1:38:53
yeah, like a healthy diet will generally be a micronutrient
1:38:56
rich diet, but don't just assume
1:38:59
that a micronutrient complete diet will
1:39:01
be the healthiest diet possible. Like don't
1:39:03
just fully conflate those two things.
1:39:06
Right. Yeah,
1:39:07
good stuff.
1:39:08
Should we get into some
1:39:10
of these questions from the audience?
1:39:12
Yeah, yeah, let's do it. Let's do it. So
1:39:15
we have I think four or five questions
1:39:17
to round out this episode. Again,
1:39:20
these were questions solicited via
1:39:22
the Facebook group and subreddit.
1:39:25
So if you want to make sure you're
1:39:27
aware of like the next time
1:39:29
we ask for questions on a particular topic
1:39:32
and therefore increase the probability that your
1:39:34
question will be answered on the show, make
1:39:37
sure to join the Facebook group and subreddit. And
1:39:39
as always, if you have questions you want to
1:39:41
ask, record a voice memo,
1:39:44
less than 60 seconds and email it to podcast
1:39:47
at stronger by science dot com.
1:39:49
So, yeah, let's let's get into these questions.
1:39:52
All right. Here's our first question from
1:39:54
Ali Shah.
1:39:56
Hey, so my question was.
1:40:00
multivitamins super overrated
1:40:02
or is there actually any use of them? Because
1:40:04
I see a lot of people that you know to kind of even
1:40:07
if they do consume an habit could
1:40:09
take different vegetables or if they don't they
1:40:12
say hey you should take a multivitamin anyway just
1:40:14
to you know cover your bases. Now I was
1:40:16
wondering if there's any actual issues to that or
1:40:18
is that completely overrated not necessary
1:40:21
you do not even need a multivitamin at all and
1:40:23
if you do do you have any recommendations?
1:40:26
Alright thank you for that question and
1:40:29
I say thanks both on behalf of myself and
1:40:31
everyone in the audience because like I
1:40:33
mentioned that was far and away the most
1:40:35
common question we got throughout this series.
1:40:38
So yeah essentially
1:40:40
like are my are multivitamins overrated?
1:40:44
So yeah I
1:40:48
kind of think so but there's
1:40:51
I think I think a fair bit of
1:40:53
nuance in answering this so
1:40:56
a lot of
1:40:57
the so most of the history
1:40:59
of multivitamins was marked by
1:41:02
very little skepticism towards them because
1:41:04
like intuitively it makes a lot of sense right
1:41:07
like you might not eat
1:41:09
a nutritionally complete diet and if
1:41:11
you can just take one little pill a day that
1:41:14
kind of serves as an insurance policy
1:41:16
it feels like a no-brainer and
1:41:19
since you
1:41:21
know a lot of people do under consume a lot of
1:41:23
micronutrients and since
1:41:25
under consumption of micronutrients is implicated
1:41:28
in a wide array of disease
1:41:30
states like it seems like a no-brainer
1:41:32
that taking a multivitamin should have at
1:41:34
worst the neutral effect on like health
1:41:37
and mortality outcomes and more
1:41:39
more likely than not a positive effect but
1:41:42
I think that that started changing
1:41:44
in 2013 when
1:41:48
a meta-analysis was published that
1:41:52
first started like throwing light on this and I
1:41:54
mean the fact that there was a meta suggests that like well
1:41:57
tells you that there were like individual
1:41:59
studies published before this but I
1:42:01
think I think people previous to
1:42:03
this meta just kind of looked at it like individual
1:42:06
studies can it might be underpowered
1:42:08
so you're gonna get some null results that
1:42:10
like aren't real yeah this 2013 meta
1:42:13
was is highly
1:42:16
cited and I think was very influential
1:42:18
for kind of cluing people into
1:42:20
the idea that maybe
1:42:23
multivitamins aren't actually
1:42:25
all that good like not bad for
1:42:27
you but like probably aren't going to do anything
1:42:31
all that great for you so the
1:42:33
title of this meta was multivitamin
1:42:35
multimineral supplementation and mortality
1:42:37
a meta analysis of randomized controlled
1:42:39
trials by McPherson
1:42:42
and colleagues published in the
1:42:44
prestigious American Journal of Clinical
1:42:46
Nutrition and yeah
1:42:49
so it it collated
1:42:52
all of the studies looking at the impact
1:42:55
of multivitamin supplementation
1:42:58
on mortality outcomes it basically
1:43:00
found like nothing so there was no
1:43:02
effect on all-calls mortality there
1:43:06
was not quite a
1:43:09
significant effect in
1:43:13
primary prevention trials like it it
1:43:15
was kind of like scratching statistical significance
1:43:17
but like yeah the the risk ratio is like
1:43:20
0.94 so like even if there was an effect there we're talking
1:43:22
like 6% like not not big
1:43:26
no effect on mortality due to vascular
1:43:28
causes no effect on mortality from cancer
1:43:33
and no statistical evidence of heterogeneity
1:43:36
or publication bias so like that's
1:43:38
brutal yeah like
1:43:40
it threw a lot of cold water on the idea
1:43:42
and
1:43:43
in
1:43:44
sense
1:43:45
then I mean that was 2013 and 10 years
1:43:47
later now and there's
1:43:49
now more like individual
1:43:52
research studies there there are more meta
1:43:54
analyses on the topic there
1:43:56
was a really good narrative review
1:43:59
from the BM
1:43:59
J in 2020 that I'll link
1:44:02
in the show notes. Overall, leading up
1:44:04
to 2013 and now since 2013, there's just not all that much promising
1:44:06
research
1:44:13
on multivitamin use. It doesn't
1:44:16
seem to
1:44:18
reduce risk of most
1:44:20
diseases, doesn't really seem to affect mortality
1:44:23
outcomes, or if it does, the effect
1:44:25
is pretty small and heterogeneous. It
1:44:28
just doesn't seem all that exciting.
1:44:32
So kind of the anti-case
1:44:35
here is that
1:44:39
for a lot of multivitamins, there might be some
1:44:42
issues with the types of vitamins or
1:44:44
minerals included. So
1:44:47
for instance, we talked about this on the
1:44:49
last episode, the
1:44:52
difference between using magnesium oxide
1:44:54
or magnesium citrate could
1:44:56
be the difference between 40% oral body and bioavailability
1:44:59
and 2%, and a lot
1:45:01
of them use oxide. Vitamin
1:45:04
D and a lot of multivitamins, they use D2
1:45:06
instead of D3, and D3 is
1:45:09
quite a bit more bioactive. So
1:45:12
it could be that maybe
1:45:14
multivitamins could be good, but
1:45:16
a lot of times they like manufacturers
1:45:18
kind of cut some corners, use cheaper ingredients,
1:45:21
whatever. So it could
1:45:23
be that.
1:45:26
Another kind of anti-multivitamin
1:45:29
argument that I've seen
1:45:31
that I'm also
1:45:33
quite sympathetic to is kind of along the lines
1:45:35
of what I was talking about at the end of the episode.
1:45:38
It might promote a bit of laziness in your diet.
1:45:40
Like, hey, I'm taking a multivitamin. I don't
1:45:43
need to worry that much about eating my fruits
1:45:45
and veggies. And so
1:45:47
you might miss out on other benefits of
1:45:50
micronutrient-rich foods. And
1:45:53
then the biggest thing is, like
1:45:55
I mentioned, the data just isn't all that promising.
1:45:58
Like if multivitamins are good, then you're not going to get a lot of money. were
1:46:00
going to do good shit for you, like now we
1:46:02
have dozens of studies on collectively
1:46:05
like hundreds of thousands if not millions of
1:46:07
subjects, if it was gonna
1:46:09
reduce risk of like cancer or cardiovascular
1:46:12
disease or all-cause mortality
1:46:14
or whatever like it should
1:46:16
show up in the data by now but like it doesn't
1:46:19
really and
1:46:21
like sometimes when you do see
1:46:23
an effect like you know it's not like
1:46:26
everything is just completely nulls
1:46:28
across the board but
1:46:31
even like some of the effects that have been observed
1:46:33
are like very small so like yeah
1:46:39
so one of the metas that will be linked in the show notes 2022
1:46:41
meta published in JAMA
1:46:44
and yeah like there
1:46:47
it found like a lower incidence
1:46:49
of cancer in people that use multivitamins
1:46:52
but that was just based on four RCTs
1:46:55
so like it's a meta but like metas can also
1:46:57
not have like like
1:47:00
an extreme amount of precision if it's based on like
1:47:02
relatively little data so yeah
1:47:05
like it was based on less data than a lot
1:47:07
of the other outcomes and the odds ratio
1:47:09
is like 0.93 so again like if
1:47:12
if it is like causally reducing risk it's
1:47:14
not reducing it very much so
1:47:16
yeah like you're seeing mostly nulls
1:47:18
and like the positive effects you do see tend
1:47:20
to be quite small and so yeah
1:47:23
the basis of the anti-multivitamin case
1:47:25
is basically just a look at the data
1:47:27
like if you're an empiricist regardless
1:47:31
of how good you think multivitamins should be
1:47:33
they don't seem to be doing what you think they
1:47:35
should and then
1:47:38
the last thing is like any intervention
1:47:41
carries risk that is often
1:47:43
I think under accounted for
1:47:45
so like
1:47:47
the the classic example of this is like
1:47:50
you would think that like
1:47:52
for preventative medicine
1:47:54
just doing like all of the screening possible
1:47:56
for everyone all the time would be
1:47:59
good and lead to better or health outcomes, but it
1:48:01
often doesn't because you might get false positives
1:48:04
and then over-treat people for things that
1:48:06
don't actually need treatment. And so,
1:48:08
just risks coming from excess screening, excess
1:48:13
treatment, whatever. And that's kind
1:48:16
of a generalizable concern
1:48:18
with any type of intervention. So
1:48:20
it very well could be that some
1:48:23
small percentage of people do benefit
1:48:26
on an individual level from multivitamin
1:48:29
use, but there might be negative
1:48:31
effects for other folks where
1:48:34
maybe, if you are consuming
1:48:36
enough of most nutrients, but you're just
1:48:38
taking a broad spectrum multivitamin,
1:48:41
maybe it's leading to excess consumption
1:48:44
of certain nutrients for some people. And
1:48:46
so, in aggregate, maybe
1:48:48
it is actually doing some good stuff for some
1:48:50
people and some bad stuff for other people, and so
1:48:52
it just kind of comes out in the wash. But
1:48:55
if you yourself aren't
1:48:57
well-informed
1:48:58
enough
1:48:59
to understand
1:49:02
which one of those two groups you'd be
1:49:04
falling into, you
1:49:06
might be doing more harm than good to yourself
1:49:08
by using something you don't necessarily need
1:49:11
to use. So that's kind of the anti-case,
1:49:14
the pro-case, which I do think
1:49:16
is still a justifiable
1:49:18
case to make. The
1:49:22
first part is what Ali alluded to.
1:49:25
It just seems like a cheap insurance policy. Multivitamins
1:49:28
are cheap. You might not consume enough
1:49:30
of every micronutrient, so kind
1:49:32
of why not? Which
1:49:35
that is countered by that
1:49:38
fourth concern in
1:49:40
the anti-case. But you might
1:49:42
wind up with excess consumption. So it's not
1:49:44
just strictly an insurance policy. You
1:49:48
can't treat it as if it has zero risk because
1:49:50
it does have some risk. The second
1:49:53
thing that the pro-case
1:49:55
might rest on is
1:49:59
someone could say, it might promote laziness
1:50:01
in your diet, like you're just taking the multivitamins,
1:50:03
you don't worry as much about consuming fruits and vegetables,
1:50:06
they could look at the data that exists that
1:50:09
shows that like people like consuming
1:50:11
multivitamins doesn't seem to increase all cause
1:50:14
mortality and they could flip that around. They could
1:50:16
be like, hey, if this is making people
1:50:18
lazier about their diets, but
1:50:21
we're not seeing an increase in disease
1:50:24
burden or an increase in mortality, and
1:50:26
these people are like being lazy with their
1:50:28
diets and still having the same health outcomes, that
1:50:31
suggests that it is actually working as that insurance
1:50:33
policy. That's true, yeah. That is a case
1:50:35
that someone could make. Another
1:50:39
thing someone could bring up when looking at the data
1:50:41
is just kind of like a methodological
1:50:44
point, which is that a
1:50:46
lot of the research,
1:50:47
like not all of it, but like most of the research
1:50:50
looking at multivitamins and like health
1:50:52
outcomes is focused on
1:50:54
kind of like
1:50:56
broad stuff. So like
1:50:58
total incidence of cardiovascular
1:51:00
disease or cardiovascular disease mortality,
1:51:03
total incidence of cancer or cancer mortality
1:51:06
and just all cause mortality. And
1:51:09
like we are getting more research on
1:51:12
like individual diseases
1:51:15
or like individual, like kind of more
1:51:17
narrow health outcomes, but like that
1:51:19
research is lagging behind the stuff on
1:51:21
stage just like all cause mortality. And
1:51:24
so there very well could be benefits that
1:51:26
the research hasn't picked up on yet because it wasn't
1:51:29
designed to look at some of those other outcomes.
1:51:32
So like for instance, like this isn't necessarily multivitamins,
1:51:35
but like calcium and vitamin
1:51:37
D are two things you'll find in basically
1:51:39
every multivitamin. And like there is research
1:51:42
showing that calcium and vitamin D supplementation
1:51:44
does seem to help decrease risk
1:51:47
of fractures in people with osteoporosis.
1:51:50
So like, you know, you could do
1:51:52
targeted supplementation when
1:51:55
someone's like diagnosed with a disease like osteoporosis,
1:51:58
they're like, oh, hey, you've been diagnosed with osteoporosis. this
1:52:00
thing, start taking calcium and vitamin
1:52:02
D, but if you're looking at it through the lens
1:52:04
of insurance policy, you could
1:52:06
say, hey, a lot of people are going to get osteoporosis
1:52:09
and just if all of them were taking multivitamins,
1:52:12
they wouldn't need to worry
1:52:14
about like this targeted supplementation
1:52:17
when they get that diagnosis. Like
1:52:20
their bases would already be covered, like it would be
1:52:22
serving its role as an insurance policy
1:52:25
and yeah, so like there's just
1:52:27
not much research on
1:52:31
kind of
1:52:32
more specific disease outcomes, like most of
1:52:34
it is on like general stuff, so like there might just be
1:52:36
benefits that the research isn't currently picking
1:52:38
up on. Another thing
1:52:40
that someone could point out as just another
1:52:43
methodological thing is
1:52:45
that most of the RCTs on
1:52:47
multivitamins are in older adults and
1:52:49
are like relatively short-term,
1:52:52
we're not talking short-term like six weeks, like a like
1:52:54
a hypertrophy study might
1:52:57
be, but like for instance
1:52:59
that 2013 review that I think kind
1:53:01
of clued people into the idea that maybe multivitamins
1:53:04
aren't all they're cracked up to be, in
1:53:06
that review the average age of the subjects was 62
1:53:09
and the average length of supplementation was 43 months
1:53:13
and it was looking at stuff like cardiovascular
1:53:15
disease and cancer, which like diseases
1:53:19
like that and I mean like most chronic
1:53:22
diseases that ultimately result in mortality,
1:53:24
like all cause mortality,
1:53:26
are at least in
1:53:28
part a result of like the sum total
1:53:30
of actions in your life, yeah and like I don't
1:53:32
want to say like that's exclusively what it is,
1:53:34
like their genetic predisposition, there's stuff
1:53:36
outside your control, but like in
1:53:38
terms of the things that are in your control, like
1:53:41
it's a cumulative progressive thing. Right,
1:53:43
a snapshot in your 60s might
1:53:45
not necessarily be very informative.
1:53:48
Correct, and so like if you were
1:53:50
trying to make the pro multivitamin case, you
1:53:53
could say like hey maybe they they
1:53:55
could do some good stuff, but like if people started
1:53:57
taking one a day in their
1:53:59
20s, and carry that throughout their
1:54:01
life, it would have positive effects.
1:54:04
But by the time someone's starting
1:54:06
to take them in their 60s, maybe like, quote
1:54:09
unquote, the damage is already done. And like, even
1:54:11
if they were theoretically having
1:54:14
some positive effects, it's like, hey, they're
1:54:16
not going to like decalcify your arteries. Like
1:54:18
you're, you're, you're mostly to the
1:54:20
way to that heart attack anyway. Like maybe
1:54:23
it pushes it off by like a month. Whereas if you've been
1:54:25
taking them for 50 years, maybe it would
1:54:27
push it back five years. You know what I mean? Right.
1:54:31
Um, like I'm not saying that's the case, but like that is like a
1:54:33
methodological consideration someone could bring
1:54:35
up.
1:54:36
Um,
1:54:37
and like, I'll also note like
1:54:40
for something that I'm far more sympathetic
1:54:42
to exercise, like I think
1:54:45
exercise is good for you. And if you exercise consistently
1:54:47
throughout your life, you'll live longer. But
1:54:50
like if you wanted
1:54:52
to apply the same sort of
1:54:54
methodological considerations to
1:54:56
exercise outcomes, the
1:54:58
epidemiological stuff looks really good. Like
1:55:01
folks who exercise, uh, have
1:55:04
like lower rates of all cause mortality and like lower
1:55:06
rates of most disease outcomes than people that don't.
1:55:10
But uh, RCTs
1:55:12
where you take people who are already in their sixties
1:55:14
and seventies and get them to start exercising,
1:55:16
there's not a ton
1:55:19
of good evidence showing that it makes
1:55:21
people live like dramatically longer. Um,
1:55:24
for I think like similar reasons.
1:55:27
Like I do think it like causally
1:55:29
makes you healthier and causally helps you live
1:55:31
longer. Right. But if you already
1:55:33
have like 60 years of
1:55:35
progression towards the disease that's ultimately
1:55:38
going to result in your demise, you
1:55:40
know, I'm like not to be too fucking morbid
1:55:43
about it, but like starting to exercise, then
1:55:45
I think we'll probably have a positive effect,
1:55:47
but like the research doesn't suggest
1:55:49
that it's like that large of an effect. Yes.
1:55:52
And so it could be a similar thing going on with multivitamins.
1:55:55
Um, and then the last thing
1:55:57
is, uh, and this is from the 2020. BMJ
1:56:01
narrative review. This
1:56:03
is a quote, people using supplements
1:56:06
tend to be older, female, and have higher
1:56:08
education income and healthier lifestyles
1:56:10
than people who do not use them. So
1:56:13
that kind of pushes back against the idea that
1:56:15
it just makes people lazy with their diet. It
1:56:18
seems to be more like folks who are
1:56:20
interested in their health are doing this
1:56:22
other thing that they think will improve their health. But
1:56:26
also that might set
1:56:29
you up with a situation where you're not
1:56:31
necessarily dealing with the ideal population
1:56:34
to detect an effect. Because
1:56:36
they're already doing a lot of other healthy things. Yeah, they're
1:56:39
doing a lot of other good shit. And
1:56:41
they might already be more
1:56:44
likely to be consuming a micronutrient
1:56:47
sufficient diet. And so the ones that take
1:56:49
a multivitamin might not actually wind
1:56:51
up with fewer micronutrient gaps in their
1:56:53
diet than the people who aren't. Like just due to
1:56:55
the population you're dealing with. So
1:56:59
yeah, like on balance, I
1:57:01
don't think multivitamins are as much
1:57:03
of a no-brainer as they would seem
1:57:05
to be if you hadn't looked into this topic
1:57:08
much. But
1:57:11
I've also seen some people who are like
1:57:13
stridently anti-multivitamin,
1:57:17
approaching it from the perspective of there
1:57:19
is no justifiable
1:57:22
cognizable reason for anyone to
1:57:24
ever use a multivitamin. It's
1:57:27
definitely a waste of money and we have
1:57:30
enough research and the right type of research to
1:57:32
be very, very confident
1:57:35
that that is the case. And
1:57:38
I'm not quite there yet. I think those folks
1:57:40
might be overplaying their hand a little bit. And
1:57:44
maybe failing to recognize some of the drawbacks
1:57:46
that are present in the current base of evidence
1:57:49
that we have on multivitamins. So
1:57:52
yeah, like I don't know. I
1:57:54
don't know if that's the
1:57:56
answer that Ali was looking for.
1:58:00
Yeah, like I would say in aggregate,
1:58:03
I mean, I don't
1:58:05
know. I think the saying like actions
1:58:07
speak louder than words kind of like me still consuming
1:58:10
plenty of sodium. Yeah, I don't think a multivitamin.
1:58:13
Yes. And you also like I have
1:58:15
talked about taking a multivitamin before and
1:58:17
you have advised me to not
1:58:20
worry about it. And I think that that speaks even
1:58:22
louder than what you do yourself. Yeah,
1:58:25
I like you more than I like myself. Yeah,
1:58:28
like I am, I think more
1:58:31
in the anti multivitamin camp,
1:58:33
like I'm, I personally
1:58:35
don't think they do much of anything. But
1:58:38
yeah, I'm not
1:58:40
like, incredibly confident about
1:58:42
that. Like I do think that there are still some gaps
1:58:44
in the research that I would like to see addressed.
1:58:48
Okay, next question from
1:58:50
Stephanie Grace Foltz.
1:58:53
Hey, Greg and Lindsay, my name
1:58:55
is Stephanie Grace Foltz. My
1:58:57
question is about vitamin D. So,
1:59:00
barbell medicine stated somewhere
1:59:02
that low vitamin
1:59:05
D is normally the result of another
1:59:07
health problem. So normally,
1:59:10
like low vitamin D by itself
1:59:12
isn't a problem, it's the result
1:59:14
of another problem.
1:59:15
So one, am I understanding that right?
1:59:18
And two, why would
1:59:20
a healthy person have low vitamin
1:59:22
D? I'm asking this because my
1:59:25
blood work came back that I have low vitamin D
1:59:27
and it's been tested multiple times and I refuse
1:59:29
to supplement because I just don't feel like dealing
1:59:31
with it. But I sleep well, I
1:59:33
eat well, I lift weights, I do cardio,
1:59:35
I don't have any underlying health problems
1:59:38
that I know of. So I'm just
1:59:40
curious, why the heck I have low vitamin D? Thanks
1:59:42
so much. And I love the show. Lindsay,
1:59:44
you're killing it girl.
1:59:46
All right, thank you for that question. And
1:59:50
so let me first say
1:59:52
that I hope nothing
1:59:55
I'm about to say will contradict
1:59:57
what the good doctors Jordan and Austin have had
1:59:59
to say. to say on the topic, and I
2:00:01
will link their podcast episode
2:00:04
in the show notes for anyone who wants to
2:00:06
listen to it, their podcast episode
2:00:08
about vitamin D. But
2:00:11
yeah, so I'll answer the second
2:00:13
question first, and then
2:00:16
just generally talk a little bit about
2:00:18
vitamin D and kind of like flesh
2:00:20
out the first question that
2:00:23
Stephanie had, but probably not fully answer it.
2:00:27
So why do you have low
2:00:29
vitamin D? Easy answer, I
2:00:31
don't fucking know. Like
2:00:34
it could be that you don't have
2:00:37
that many like rich sources of vitamin D
2:00:39
in your diet. It could
2:00:41
be that you lead like a generally healthy
2:00:43
lifestyle, but I don't
2:00:45
know, you're from Massachusetts
2:00:48
and you get direct enough
2:00:50
sunlight for vitamin D synthesis like four
2:00:53
months out of the year, and you're not outside
2:00:55
all that often. Like those, it could
2:00:57
be lifestyle, could be diet, could
2:00:59
just be random. Why
2:01:02
you as an individual have low vitamin D, I
2:01:04
have no earthly idea. And
2:01:06
if that's something you wanna get to the bottom of, that
2:01:09
is something to work on with your doctors. So
2:01:13
yeah, then just to kind of talk
2:01:15
a little bit more about
2:01:18
the first part of that question, the
2:01:21
idea that low
2:01:23
blood vitamin D is often
2:01:26
indicative of poor health rather
2:01:29
than the cause of poor health, that
2:01:31
is true. And I think it's something
2:01:34
that not all that many people are like
2:01:36
super aware of. There is,
2:01:39
like I think there's
2:01:41
a movement around what's termed the
2:01:43
vitamin D hypothesis, which like
2:01:46
most hypotheses in, like
2:01:49
most like sweeping hypotheses
2:01:51
and like health related stuff is like,
2:01:54
if it's
2:01:55
right to some extent, it's like oversimplified
2:01:58
to the point of being wrong. Yeah. And
2:02:00
it's predicated on the idea that like when
2:02:02
you look at epidemiological research,
2:02:06
like looking at the association between
2:02:09
blood levels of vitamin D or
2:02:11
like the main biomarker you look at,
2:02:14
which is serum 25-hydroxy
2:02:16
vitamin D, which is often written as 25-OHD
2:02:18
or 25-OHD 3, like
2:02:23
blood levels of like that particular
2:02:26
biomarker of vitamin D are like strongly
2:02:29
associated with a ton of positive health outcomes.
2:02:32
Like if you have higher blood levels of 25-OHD, like
2:02:36
generally you have lower risk
2:02:38
of cancer, like lower risk of heart
2:02:41
disease, lower risk of
2:02:43
like dementia, lower risk of like
2:02:46
all-cause mortality, like pretty
2:02:48
much any positive health outcome you would
2:02:50
want, that is associated with higher
2:02:52
blood levels of vitamin D. But,
2:02:55
you know, classic principle, correlation does
2:02:58
not necessarily imply causation or
2:03:00
if you want to get even a little fancier,
2:03:03
correlation that does imply causation doesn't
2:03:06
necessarily imply the direction of the causation.
2:03:09
And in this case, I kind
2:03:12
of think it's a bidirectional, like sometimes
2:03:15
if your like blood levels of vitamin
2:03:17
D are too low, like
2:03:20
that could be a causal factor
2:03:22
in disease progression or like the
2:03:24
risk of like developing a disease in the first place.
2:03:27
But also like Stephanie
2:03:30
alluded to, oftentimes
2:03:33
low blood levels of vitamin
2:03:36
D aren't the cause of a disease but are
2:03:38
like indicative of disease
2:03:40
states or like poor health. So
2:03:43
yeah, like the most
2:03:45
basic epidemiological research finds
2:03:48
like positive associations between
2:03:50
high blood levels of vitamin D and all sorts of positive
2:03:52
outcomes. But when you go like
2:03:55
one step deeper, there's not
2:03:57
a super strong association between dietary
2:04:01
vitamin D intake and serum
2:04:03
vitamin D status. There's
2:04:06
also not a super strong association
2:04:09
between sun exposure, even
2:04:11
when corrected for like latitude and like skin
2:04:13
melanation and all of that, and serum
2:04:15
vitamin D status. Like the
2:04:18
associations there, but
2:04:20
like it's not as strong as one would anticipate
2:04:22
just kind of like going down like the causal
2:04:25
chain that one would think. RCTs
2:04:29
testing the effects of increased sun
2:04:31
exposure and increased vitamin D
2:04:33
intake on vitamin D status generally
2:04:37
do find increases in serum
2:04:40
vitamin D, but the increase
2:04:42
usually isn't particularly
2:04:44
large and it tends to be highly variable.
2:04:47
And in general, it
2:04:49
mostly seems to be effective for people who have
2:04:51
like really low serum levels in the first
2:04:53
place. So like, as
2:04:57
always, I forget what the units are for
2:04:59
this, but like the like
2:05:01
number for like blood levels
2:05:04
of 25-OHD, it's like
2:05:06
anything under 20 is considered deficient
2:05:10
and like different health bodies have like different
2:05:12
numbers they put on this, but like in general, under
2:05:15
like 15-20 is considered deficient, under
2:05:18
like 30-40 is considered insufficient,
2:05:20
and then a lot of people say like, oh, try to keep it above 50,
2:05:23
and some people even say try to keep it above 75. And
2:05:28
in general, what you see is like in
2:05:31
studies where they look at the effects of increased
2:05:33
sun exposure or just like UV exposure or
2:05:35
increased vitamin D intake on
2:05:38
serum vitamin D status, for
2:05:40
people who have like serum
2:05:43
levels at baseline in the 10, 15, 20 range,
2:05:47
you do tend to see increases. But
2:05:50
if someone's like in the 25, 30, 35 range, oftentimes
2:05:55
it doesn't do anything, or like if it has an
2:05:57
effect, like it's a pretty small effect, like it does.
2:06:00
It doesn't seem like people can reliably
2:06:02
sun exposure or vitamin D intake
2:06:04
their way to serum levels
2:06:07
in the 50 to 75 range. So
2:06:11
yeah, usually the effect
2:06:13
isn't large, tends to be highly variable, and
2:06:15
tends to be mostly observed for people who have below
2:06:17
a status at baseline. And
2:06:21
another complicating factor is serum
2:06:23
vitamin D status isn't always indicative
2:06:25
of molecular vitamin D status, which
2:06:28
this one's a bit of a mind
2:06:30
fuck, and I'm not gonna get into it, but there
2:06:33
have been observed cases of people
2:06:35
who have mild
2:06:38
vitamin D toxicity within
2:06:41
particular cell types that bioaccumulate
2:06:43
it, but still low levels of 25-OHD in
2:06:46
the blood. So
2:06:48
the screening test itself might be
2:06:51
kinda sketchy. For some people, there
2:06:53
are factors that can influence cellular
2:06:56
accumulation versus circulating levels
2:06:58
in the blood. And
2:07:02
also, it's likely that causation
2:07:04
goes in both directions. So low vitamin
2:07:07
D may be causally linked to some disease, because
2:07:13
vitamin D is a steroid hormone,
2:07:16
it has direct effects in almost
2:07:18
all cell types, and
2:07:21
it's linked to, it has impacts
2:07:23
on immunity and things
2:07:26
that modulate
2:07:29
inflammatory status, and
2:07:33
things that are either associated with
2:07:35
or causally affect
2:07:37
disease progression for some diseases. And
2:07:40
so I do think it is quite possible
2:07:42
that if your
2:07:44
vitamin D levels are low enough, that could
2:07:47
causally increase your risk of some diseases, but
2:07:49
it is also the case. And I think,
2:07:53
as Stephanie alluded to, and
2:07:55
as Jordan and Alston cover
2:07:57
in their episode,
2:07:59
it is probably...
2:07:59
probably more often the case that
2:08:03
when you get sick, getting sick
2:08:06
is what reduces your serum vitamin D
2:08:08
levels due
2:08:11
to changes in vitamin D metabolism,
2:08:14
due to changes in tissue usage of
2:08:16
vitamin D, or potentially due to
2:08:18
secondary behavioral effects. Oftentimes
2:08:21
if you're sick and not feeling good, you're not spending
2:08:23
a ton of time in the sun. Right. It
2:08:27
sometimes could be as simple as that. Oftentimes
2:08:31
low vitamin D is reflective of
2:08:33
poor health rather than the cause of poor health.
2:08:36
And if that's the case, consuming more vitamin
2:08:38
D may not have much of an impact on
2:08:41
your serum levels of vitamin D. But
2:08:44
if you have low vitamin D
2:08:47
status because you consume very little
2:08:49
vitamin D or you just get no sun exposure,
2:08:52
then consuming more vitamin D and getting
2:08:54
more sun exposure will probably help.
2:08:57
So yeah, basically like TLDR
2:08:59
it's complicated and don't
2:09:02
construe any of this as medical advice. But
2:09:05
yeah, the relationship between like vitamin
2:09:08
D intake and vitamin D status
2:09:11
is far from a direct one-to-one relationship.
2:09:15
And even though like
2:09:19
blood levels of vitamin D are associated with
2:09:21
your risk of a bunch of diseases, that doesn't necessarily
2:09:23
mean that like being in the sun more
2:09:25
and consuming more vitamin D will like causally
2:09:28
reduce your risk of those diseases because you
2:09:30
could have low vitamin D status because you
2:09:33
are already like developing those diseases. And
2:09:36
yeah, beyond that, if you
2:09:39
want to know what's going on
2:09:41
for you as an individual, talk
2:09:43
to your doctor because there
2:09:46
are so many like individual discrete
2:09:48
things that could be going on. I
2:09:51
could not possibly know why you have low
2:09:53
vitamin D status and whether that's
2:09:55
indicative of low intake or the fact
2:09:57
that you're already sick or like...
2:09:59
Something else, just weird stuff about
2:10:02
vitamin D metabolism. Maybe you have a bunch in
2:10:04
your cells and not much in your blood. I
2:10:06
don't know what's going on for
2:10:09
any person who wants to know.
2:10:12
Yeah.
2:10:14
Thanks for the shout out, Stephanie.
2:10:17
Okay, next question from
2:10:20
Joel Phillips. Stephanie
2:10:23
not thinks for the shout out. If
2:10:27
Lindsay gets too big of a head, she will realize
2:10:29
that she's much better than me and leave
2:10:32
me alone and desolate. That
2:10:34
is my greatest fear. Okay,
2:10:36
next question from Joel Phillips.
2:10:39
Hi guys. With micronutrient
2:10:41
counting often being laborious, time
2:10:44
consuming and sometimes infeasible, given
2:10:47
a lack of available data for many different foods,
2:10:50
are there any good proxy measurements that could
2:10:52
help you tell whether you are reaching the recommended
2:10:54
targets on average without actually
2:10:56
having to meticulously track each food
2:10:58
and micronutrient you eat?
2:11:00
For example, could you count
2:11:02
the grams of vegetables, fruits and
2:11:04
whole grains you eat per day?
2:11:06
Or could you eat specific amounts of a
2:11:08
few specific vegetables that when
2:11:11
combined seem to end up hitting most
2:11:13
micronutrient targets for most people? Thanks
2:11:15
guys. Yeah, so thank
2:11:18
you for the question. And to answer
2:11:20
it, I think not
2:11:22
really, at least not
2:11:25
a proxy measure I would feel good about. But
2:11:29
I'm like, I'm a stickler for if I'm
2:11:31
going to propose something as a proxy measure, it has
2:11:33
to be valid and reliable and like blah, blah, blah.
2:11:36
Yeah, there's nothing
2:11:38
that would clear my bar as a good
2:11:40
proxy measure for this. But
2:11:43
like, in general, to kind
2:11:45
of answer the question conceptually, I think
2:11:49
that you're in pretty good shape if you consume
2:11:51
a diet comprised of whole
2:11:53
foods with plenty of fruits, veggies, whole grains,
2:11:56
nuts, seeds, mushrooms,
2:11:58
etc.
2:11:59
Like
2:12:01
you're probably in good shape. And if you're
2:12:03
consuming like a little bit
2:12:05
less of a particular micronutrient than may
2:12:07
theoretically be optimal, like you'll probably
2:12:09
be close enough that like you won't even notice
2:12:12
and like it'll be fine. As
2:12:14
to the question about specific foods
2:12:17
to maybe pay mind
2:12:19
to, we actually
2:12:21
mentioned some of them earlier
2:12:24
in the episode. So like green
2:12:26
leafy vegetables rock and the
2:12:28
ones that show up like most often is
2:12:30
like individual green leafy vegetables
2:12:34
that are like very micronutrient dense.
2:12:37
Spinach, kale, chard and mustard
2:12:39
greens were the ones that showed up a lot. Peppers
2:12:43
pop up kind of a lot and
2:12:45
mushrooms as well. And mushrooms
2:12:48
like mostly for the weird ones.
2:12:51
And shellfish also
2:12:54
pops up kind of a lot, particularly
2:12:57
for certain minerals and
2:12:59
liver as well. Like
2:13:03
in terms of like micronutrient
2:13:05
dense animal products, like the liver
2:13:08
is about as good as you can do. And
2:13:11
then also like we mentioned before, nori
2:13:14
shows up a lot and
2:13:17
just kind of like seaweeds and
2:13:20
algaes in general tend to
2:13:22
be quite good. If
2:13:24
you're looking for just like specific things to
2:13:27
check out. And as mentioned previously,
2:13:30
don't get like too hyper fixated on that
2:13:32
because like fruits in general and like berries
2:13:35
and cherries in particular are really great.
2:13:38
But also like aren't that micronutrient dense?
2:13:40
Like don't get too focused on just micronutrients
2:13:43
even from like whole food sources and
2:13:46
miss out on some great foods that don't have the highest
2:13:48
micronutrient density in existence. Okay,
2:13:54
second to last question from
2:13:56
Nick.
2:13:59
Hello, my name is Nick. My
2:14:02
question would be in regard to folic acid
2:14:04
supplementation, especially in family planning situations.
2:14:07
In Europe you have a lot of FUD
2:14:10
in regards to folic acid supplementation
2:14:13
when it comes to prenatal and postnatal
2:14:15
phases and the
2:14:18
impression is given that women are
2:14:20
not even able to conceive when not
2:14:23
supplementing with folic acid. My
2:14:25
understanding would be that folic acid is mainly
2:14:28
needed for establishing the umbilical
2:14:30
cord and laying the foundations of the spinal
2:14:32
cord but not much more. It would
2:14:34
be great if you could give a rundown
2:14:36
on actual supplementation needs, especially
2:14:39
in context with a well-balanced or good
2:14:42
diet in Western civilizations.
2:14:45
Thank you very much and keep up the good work.
2:14:48
All right.
2:14:50
So thank you for the question and
2:14:53
I'm going to attempt to answer it without
2:14:55
getting myself in too much trouble because
2:14:58
I'm not an OBGYN
2:15:01
and I feel like it
2:15:04
will be very challenging to answer
2:15:06
this question without it sounding like I'm
2:15:08
giving medical advice which is
2:15:10
not my intention. But
2:15:13
yes, I'll try to talk about this question
2:15:15
and this topic in kind of general terms
2:15:19
and hope I don't get too far out over my skis.
2:15:22
So just in general, before
2:15:25
I start talking about this, I
2:15:28
will note some resources that I'll link
2:15:30
in the show notes here. One is
2:15:32
a good review from 2011 that
2:15:35
I think is still like quite up to date. Like I
2:15:37
don't think there's been a ton
2:15:39
of development in this area since then. But
2:15:43
for a more recent source,
2:15:46
I'm also going to link like a little back and forth
2:15:48
from the Lancet in 2022. There
2:15:51
essentially was a review, like
2:15:54
a narrative review, like a cheerleading the idea
2:15:57
that folic acid food fortification
2:15:59
should... be like mandatory and universal.
2:16:02
And there was a letter to the editor disagreeing
2:16:05
with that perspective. And it
2:16:07
mostly follows the stuff in the 2011 review.
2:16:10
But if, if you're concerned that, ah,
2:16:12
there's an expiration date on science, like
2:16:15
you're fine with the 2011 review, but if you
2:16:17
want something more up to date, there is some stuff
2:16:19
from 2022 as well. Um,
2:16:21
so yeah, just in general,
2:16:24
the main purpose
2:16:27
of, uh, like recommending folic
2:16:29
acid supplementation to women
2:16:32
who are like, depending on the context,
2:16:34
either, um, like intentionally
2:16:36
trying to become pregnant or, um, sometimes
2:16:39
the recommendation is given just to women of
2:16:42
childbearing age who are sexually
2:16:45
active and might become pregnant
2:16:47
in an unplanned way. Um,
2:16:49
but yeah, like it's, it's pretty common
2:16:51
for, um, doctors
2:16:54
to recommend prenatal vitamins
2:16:56
and kind of there, I mean, they're
2:16:59
basically multivitamins, but like the thing that they're,
2:17:02
um, like the, the thing in particular
2:17:05
that characterizes them is, uh, folic
2:17:08
acid fortification. So they
2:17:10
tend to have either 400 or 800 micrograms of folic acid. And
2:17:14
that is, uh, like most health
2:17:17
bodies recommend, um, women
2:17:19
who are pregnant or trying to become pregnant
2:17:21
to take a folic acid supplement. Uh,
2:17:24
so as, as you alluded to
2:17:26
Nick, the two
2:17:29
main things that, that that's involved with
2:17:31
is the, the development of the umbilical
2:17:33
cord and also, um, like preventing
2:17:35
neural tube defects and more so the neural
2:17:37
tube defects in the umbilical cord, um,
2:17:42
and the, the main one
2:17:44
that people are concerned about is spina
2:17:46
bifida, like that's the disease
2:17:49
most often resulting from a fetus
2:17:53
with a neural tube defect that still goes to
2:17:55
term. Um, and
2:17:57
so yeah, like in general, um,
2:18:00
either food fortification
2:18:02
with with folic acid or
2:18:04
like vitamins with folic acid are
2:18:08
very effective at preventing
2:18:11
most neural tube defects like that's
2:18:13
not particularly controversial when
2:18:18
folic acid fortification started in
2:18:20
the u.s and like other parts of the of the
2:18:22
developed world miscarriages
2:18:24
due to neural tube defects went down babies
2:18:28
born with diseases like spina bifida as
2:18:30
a result of neural tube defects decreased
2:18:33
Like it works for that purpose
2:18:37
And like it's it's very much
2:18:39
not the case that women can't conceive without
2:18:41
taking a folic acid supplement I mean like most
2:18:44
of the world doesn't have access to folic acid
2:18:46
supplements and I mean
2:18:49
people in general didn't have folic acid supplements
2:18:52
until what probably the 60s or 70s and
2:18:54
like we made it this far as the species like A
2:18:58
lot of babies are born and have been
2:19:00
born without it. Although like I
2:19:02
understand that that was that was hyperbole So
2:19:07
the the anti case Like
2:19:11
spelled out in the letter to the editor
2:19:13
from in the Lancet in 2022
2:19:15
that will be linked in the show notes Mostly
2:19:19
has to do with the fact that one although
2:19:23
folic acid supplementation is
2:19:25
very effective at preventing most
2:19:27
neural tube defects Neural
2:19:29
tube defects themselves are also
2:19:31
relatively uncommon so the
2:19:34
estimated like global prevalence
2:19:37
of Pregnancies with neural tube
2:19:39
deep with a fetus with neural tube defects
2:19:41
is like about two per thousand
2:19:43
pregnancies So,
2:19:45
you know, that's it's not like a one in a million
2:19:48
thing, but it's also not like super common and There
2:19:51
is now starting to be some
2:19:53
concern that Folic acid
2:19:55
supplementation in some cases
2:19:58
may do more harm than good In
2:20:00
particular, when it's coupled with a B12
2:20:03
deficiency. So
2:20:06
there's some research in older adults suggesting
2:20:09
that folic acid supplementation, when
2:20:11
coupled with either a B12
2:20:13
deficiency or just generally low levels of B12
2:20:15
intake, has
2:20:18
been linked to cognitive
2:20:21
decline. And I think the
2:20:23
jury's still out about whether that's
2:20:25
a causal relationship or not. And
2:20:28
there's also some research from India suggesting
2:20:31
that women taking folic
2:20:33
acid supplements with, who
2:20:35
also have low B12 status, their
2:20:39
children tend to have higher rates of
2:20:43
obesity and insulin resistance. Which
2:20:45
again, it's not entirely clear
2:20:48
if that's just a correlation or causal. Both
2:20:53
of those things could just kind of be correlates with poverty,
2:20:55
like people who have diets lower in
2:20:57
B12. They might have some other
2:20:59
factors going on that would predispose them
2:21:02
to increase risk of cognitive decline
2:21:04
or obesity or insulin resistance in their children.
2:21:07
So yeah, the anti-case I
2:21:09
don't think is ironclad. There
2:21:14
are some research findings that give people a
2:21:16
bit of calls for concern. So
2:21:21
my recommendation is just do whatever
2:21:23
the fuck your doctor tells you to do. I'm
2:21:26
absolutely not going to go against that. And
2:21:30
yeah, it is, there
2:21:33
is a reason that they recommend folic
2:21:35
acid supplements and folic acid
2:21:38
food fortification is a pretty common
2:21:40
thing. And that is because that
2:21:42
is very effective at preventing
2:21:44
a lot of types
2:21:47
of neural tube defects. There
2:21:49
are causes other than folate deficiencies
2:21:52
that can cause neural tube defects, a lot of them
2:21:54
are related to folate deficiencies.
2:21:57
And yeah, they work really, really well for that.
2:22:00
And
2:22:01
I think the scientific consensus is
2:22:04
that, like
2:22:06
for most people most of the time the benefits outweigh
2:22:08
the risks. And if you want to
2:22:12
deal with it more than that on an individual
2:22:14
level, again, that's I think a conversation
2:22:16
to have with your doctor. Okay,
2:22:20
last question from Charles Bose. Two
2:22:25
questions about micronutrients. First
2:22:28
is about taking vitamin K with
2:22:30
vitamin D. I was wondering
2:22:32
what the evidence is behind
2:22:34
taking vitamin K along with vitamin
2:22:36
D, specifically on the impact
2:22:38
on cardiovascular disease risk, because I've seen
2:22:40
this recommended many times. The
2:22:44
other questions about boron, I've
2:22:46
seen boron supplementation kind of feel
2:22:48
increasingly recommended. I was wondering
2:22:50
what the evidence actually says about supplementing
2:22:54
with boron. All
2:22:56
right, Charles, thank you for those questions. So
2:22:59
yeah, starting with the first one,
2:23:03
supplementing vitamin K along with
2:23:05
vitamin D. I
2:23:08
think that that's something that we'll know
2:23:10
more about in a couple years. So there
2:23:13
is some promising epidemiological
2:23:16
evidence related to vitamin
2:23:19
K status and vitamin K intake
2:23:24
related to heart disease outcomes. So
2:23:27
people who eat more vitamin K and people
2:23:30
who have better serum
2:23:32
vitamin K status tend
2:23:35
to have lower rates of cardiovascular
2:23:37
disease and cardiovascular disease mortality.
2:23:40
But much like we've
2:23:43
covered, I feel like multiple times just
2:23:45
in this episode, correlation is not
2:23:47
always causation. And
2:23:51
yeah, in this case, it could be that
2:23:54
supplementing with vitamin K does
2:23:56
cause positive cardiovascular health outcomes.
2:24:00
Or it could just be a mere association that's
2:24:02
showing up in the research to this point. There
2:24:06
are, I believe, high-quality
2:24:10
RCTs underway. Most
2:24:13
of the randomized control trials that exist
2:24:15
to this point on vitamin K supplementation
2:24:18
are relatively short
2:24:20
and have relatively small samples and are
2:24:22
relatively inconclusive. The
2:24:26
idea behind vitamin
2:24:28
K supplementation is that
2:24:32
so vitamin K is a co-factor
2:24:35
for a protein called,
2:24:38
that's often just referred to as MGP
2:24:41
or matrix GLA protein,
2:24:45
which helps
2:24:47
prevent arterial calcification.
2:24:51
And so vitamin D helps with
2:24:53
calcium absorption. And
2:24:56
D and K are both implicated in
2:24:58
calcium metabolism generally. And
2:25:01
so there are some people that recommend
2:25:03
them to be taken together to
2:25:07
help prevent arterial
2:25:09
calcification. Due
2:25:12
to the effects on MGP.
2:25:17
And yeah, the mechanism makes sense.
2:25:19
The epidemiological research
2:25:22
is promising. But
2:25:24
yeah, at this point before, one,
2:25:27
I personally wouldn't be making this
2:25:29
recommendation in the first place because we're talking
2:25:31
about a recommendation for a specific disease
2:25:34
outcome. That's for doctors to
2:25:36
make. But in terms of something
2:25:39
I would feel confident making a statement about,
2:25:41
if not a recommendation, at this
2:25:44
point I want to see RCTs
2:25:47
because correlations don't always
2:25:49
pan out to causal
2:25:52
effects on disease risk or various
2:25:54
outcomes in practice. And
2:25:57
yeah, as I understand it, Research
2:26:00
is currently underway that will give more
2:26:03
clarity on that topic But
2:26:05
yeah, we're just kind of waiting
2:26:07
for it to be published Yeah,
2:26:10
it's it's promising but but not conclusive
2:26:12
that's that's kind of what I would say about vitamin
2:26:14
K for
2:26:17
boron I
2:26:21
Both both thank you for asking this question
2:26:23
and also resent you for asking this question
2:26:25
because I've known that
2:26:28
Excitement about boron has been kind
2:26:30
of floating around for a while, but
2:26:33
I don't know why for some reason It's just not something
2:26:35
I wanted to look into I
2:26:38
Think it's because like a lot of the people
2:26:40
promoting boron are folks who generally
2:26:42
annoy me because like like
2:26:45
it's been It just
2:26:48
based on like my kind of fitness
2:26:50
media consumption diet I'm
2:26:52
stuff related to boron has been inescapable
2:26:55
and like most of the more promising
2:26:57
stuff I think relates to like bone
2:26:59
health and like osteoarthritis but
2:27:02
the people that talk about boron the most
2:27:04
tend to be like Folks who
2:27:06
kind of straddle the line between fitness
2:27:09
influencers and masculinity influencers
2:27:11
because There are
2:27:13
like a couple of small studies
2:27:16
suggesting that like boron supplementation
2:27:18
may increase testosterone levels a little bit
2:27:20
Yeah and so like if
2:27:23
if if any like non-pharmaceutical Increases
2:27:26
testosterone like the most
2:27:28
annoying people on the internet are never going to
2:27:30
shut the fuck up about it And I think
2:27:32
I think that that's the reason that I haven't
2:27:34
wanted to look into it more So
2:27:36
anyway, thanks for the question because it forced
2:27:39
me to look into it a little bit more and
2:27:43
so yeah to kind of Provide
2:27:46
a good resource to check out there
2:27:48
is a 2015 paper
2:27:51
that I Suspect is
2:27:53
where a lot of the optimism about
2:27:55
boron came from and like one of the
2:27:57
things that got people talking about it More cuz like I don't
2:28:00
remember people talking about boron in
2:28:02
like 2013 which is like a time
2:28:05
when I was dumber and I would have been
2:28:07
far more interested in people saying like oh this thing
2:28:09
increases testosterone because I used to think that was
2:28:12
like way more important than it actually is um
2:28:15
but yeah like I don't remember people talking about boron
2:28:17
in like 2012 2013 like it does seem to be like a post 2015
2:28:21
thing and this paper has been cited
2:28:23
like over 300 times so it's been pretty
2:28:26
influential like and so I suspect
2:28:28
this is where a lot of
2:28:30
the the chatter about it originated
2:28:32
and where a lot of the optimism came from and uh
2:28:36
this paper one like has a
2:28:38
good title like it has a catchy title for a
2:28:40
scientific paper it's nothing boring
2:28:42
about boron um and
2:28:45
the author is uh pizorno
2:28:47
um and
2:28:50
uh oh the the main degree listed
2:28:52
behind his name is mdiv master of
2:28:54
divinity which I think uh
2:28:57
is definitely the credential you would want for
2:28:59
studying boron um but anyway
2:29:02
uh like I'm
2:29:04
not trying to talk shit like I just
2:29:06
have so much like resistance built
2:29:08
up around this right the people who talk about
2:29:11
boron annoy me so much um but
2:29:13
yeah so like
2:29:13
this is
2:29:15
it's a decent paper it's um um
2:29:18
I would say less of an objective
2:29:21
evaluation of all
2:29:23
of the evidence and more kind
2:29:25
of like a cheerleading paper where
2:29:28
uh which is which is totally
2:29:30
fair totally fine it's just something to
2:29:32
be aware of going into it where
2:29:34
it's someone who's like specifically
2:29:37
trying to make the affirmative case
2:29:40
that boron is good for a bunch of these outcomes
2:29:42
and that people should supplement with boron so
2:29:45
it yeah it covers all of the evidence
2:29:47
like in favor of it but you
2:29:49
know isn't isn't going to uh spend
2:29:52
a lot of time discussing like some of the weaknesses
2:29:55
or like drawbacks in the current body of evidence
2:29:57
so like
2:29:58
if you're like
2:29:59
if you're like me and kind
2:30:02
of a boron skeptic, or if you're just uninformed
2:30:04
about this and you want to know why people are excited
2:30:07
about it, I think this is not a bad
2:30:09
place to start.
2:30:12
And in general,
2:30:16
there are studies
2:30:19
finding outcomes
2:30:23
that seem pretty promising. So
2:30:25
like I said, I think most of
2:30:28
the stuff that is the closest
2:30:30
to being solid is looking
2:30:32
at like effects on bone health or like
2:30:36
function and pain in people with osteoarthritis.
2:30:39
Although there's also some stuff
2:30:42
looking at like
2:30:44
boron supplementation reducing inflammatory
2:30:47
biomarkers. And begrudgingly,
2:30:50
there is some research suggesting that
2:30:52
boron supplementation may increase
2:30:54
testosterone levels. Although that research
2:30:57
is a little bit nuanced because
2:31:01
it also suggests that like there might
2:31:03
be potential boron toxicity
2:31:05
reducing testosterone levels. So
2:31:08
like in one study they use
2:31:10
like, in general,
2:31:12
I think what would be considered a relatively
2:31:14
low dose of like two or three grams a day and
2:31:17
an even lower dose of like 500 milligrams. And
2:31:21
at like a week or two weeks, there
2:31:23
was a larger increase in testosterone in the group
2:31:25
taking like two or three grams a day. But
2:31:28
like six weeks later, that group actually
2:31:30
experienced a small decrease in testosterone.
2:31:33
But the group taking like 500 milligrams
2:31:35
was still like, it
2:31:40
appeared that they were experiencing a continued
2:31:42
increase in testosterone. Which
2:31:44
suggests that like boron might bioaccumulate
2:31:46
in the testes and if you consume
2:31:48
too much and you're interested in the testosterone
2:31:51
outcomes, like maybe it's gonna do more harm
2:31:53
than good. Anyway,
2:31:55
not something I would take for testosterone because it seems
2:31:58
like there's some unresolved. of
2:32:00
questions and I don't know
2:32:02
kind of skeptical about that one um
2:32:06
but yeah like like basically there is I would
2:32:08
say some calls for optimism but I
2:32:10
would also temper
2:32:13
excessive optimism on this topic
2:32:15
with a couple things one
2:32:18
is that most of the research has
2:32:21
just looked at outcomes and there's
2:32:23
not that much mechanistic stuff so
2:32:25
like there there
2:32:28
are some like positive findings related
2:32:30
to like osteoarthritis like pain and
2:32:32
function but like I can't tell you why
2:32:35
those findings were observed and
2:32:37
like you don't you don't need to
2:32:39
know a mechanism for like an effect
2:32:42
to be real but for
2:32:44
me to evaluate how plausible
2:32:47
I find these findings a mechanism
2:32:49
sure would be fucking helpful um
2:32:52
because and this is like the other
2:32:54
kind of uh thing
2:32:56
I would say to temper some of the optimism
2:32:59
around this most of the
2:33:01
research finding positive effects
2:33:03
from boron supplementation tend
2:33:05
to be relatively small studies
2:33:09
um and tend to be relatively short
2:33:11
term
2:33:12
and tend to be studies that would be pretty
2:33:15
cheap to run and
2:33:16
that's like the perfect
2:33:19
uh
2:33:20
set of circumstances for
2:33:23
just like the the
2:33:26
wonders of publication bias to do its
2:33:28
thing and um just
2:33:31
wind up with a bunch of null
2:33:33
findings that are just in a file drawer
2:33:35
somewhere with the handful of positive
2:33:37
findings getting published and therefore
2:33:39
like a pretty unrealistic and
2:33:41
like unrepresentative view of the research
2:33:44
so like I don't know I don't
2:33:47
I don't know how seriously
2:33:49
to take this stuff I do strongly
2:33:51
suspect that if boron supplementation
2:33:54
does have some of the positive effects that have been
2:33:56
observed the magnitude of the
2:33:58
effect is probably considerably smaller
2:34:01
than the current body of evidence would suggest
2:34:03
it is because again like it
2:34:05
is currently the perfect body of evidence
2:34:08
for there to just be false positives,
2:34:10
file drawer effect, like null findings not
2:34:13
getting published, therefore like leading
2:34:15
to an inflated perception
2:34:18
of like what the effect magnitudes are and
2:34:21
like until some like more solid
2:34:23
mechanisms are identified like I retain
2:34:27
like a healthy level of skepticism
2:34:30
that it works if I don't have like
2:34:32
a good like at least a reasonable
2:34:35
understanding of how it could work. So
2:34:39
yeah I don't know like that's that's
2:34:41
about where I'm at but kind
2:34:43
of the thing I want to end on
2:34:46
is that 2015 paper which like
2:34:48
I said is kind of like a cheerleading paper
2:34:50
for boron supplementation.
2:34:54
It
2:34:55
recommends supplementing with three grams
2:34:57
of boron per day but it also
2:35:00
says quote a
2:35:02
diverse plant food rich diet is estimated
2:35:05
to provide approximately 1.5 to 3 milligrams
2:35:08
per day of boron foods of plant
2:35:10
origins especially fruits leafy vegetables
2:35:13
nuts and legumes are rich in boron as
2:35:15
our plant derived fermented beverages ie
2:35:17
wine cider and beer meat fish
2:35:19
and dairy products however are poor sources peanuts
2:35:22
and peanut butter other nuts raisins wine
2:35:24
and avocado are also top contributors
2:35:27
to boron intake although coffee
2:35:29
and milk are low in boron they provide 12% of
2:35:31
total boron intake in the United States due
2:35:33
to the volume consumed and the fact that
2:35:35
the standard American diet contains so
2:35:38
few servings of fruits vegetables and legumes.
2:35:42
So like
2:35:43
going back to where we ended
2:35:45
this episode on like if boron
2:35:47
does a lot of this good stuff I
2:35:50
kind of think like just try to eat some fruits and veggies
2:35:53
like a generally healthy diet
2:35:57
like like due to like
2:35:59
due to the fact that it might bioaccumulate
2:36:02
in tissues, particularly the testes,
2:36:05
and there's so many unresolved questions.
2:36:09
I think that
2:36:11
supplementing with it would be relatively
2:36:14
unwise, especially at reasonably
2:36:16
high doses. Because yeah,
2:36:20
I just feel like we're playing with fire and
2:36:22
there's too many unresolved questions. But
2:36:26
there are no downsides and
2:36:28
plenty of upsides to eating plenty of fruits and vegetables.
2:36:31
So if you're interested
2:36:34
in boron for bone health, for
2:36:37
modulating inflammation, for
2:36:40
possible effects on osteoarthritis, for possible
2:36:42
effects on testosterone, for any of it. That's
2:36:46
cool. I don't want to completely
2:36:48
trample on your optimism, but the recommendation
2:36:51
I would give for boron consumption
2:36:53
is to skip the supplementation, just eat fruits
2:36:56
and veggies. Because
2:36:58
then even if none of the shit related to boron
2:37:00
pans out, there are other benefits to
2:37:02
eating fruits and veggies, and you'll
2:37:06
still come out ahead. Whereas if you just
2:37:08
took a boron supplement,
2:37:11
you wouldn't if
2:37:13
this stuff doesn't pan out.
2:37:14
So yeah, that's
2:37:18
all we have for this episode. That is it for the
2:37:20
questions. Yeah. Fat Bear
2:37:22
Week is underway just to confirm.
2:37:25
Oh, hell yeah. Give us some updates.
2:37:27
So they
2:37:28
have the left side of the bracket all filled
2:37:30
out. On
2:37:33
the left side of the bracket, 901, my current favorite.
2:37:37
She's a mama bear. Very cute,
2:37:39
very traditional bear shape. Very
2:37:42
impressive transformation.
2:37:44
480 Otis this year, not
2:37:47
as impressive. It
2:37:49
looks like he didn't get as much food. 128 Grazer
2:37:53
though, an absolute unit once
2:37:55
again.
2:37:55
Ooh, hell yeah. Looking
2:37:58
absolutely insane. I
2:38:00
might be jumping back on the Grazer train.
2:38:03
151 Walker is the one they're introducing
2:38:05
right now. He looks great.
2:38:08
He's so big. He's
2:38:10
just sitting
2:38:11
in the water. Hell yeah. Licking his chops.
2:38:14
It looks like it's gonna be a great year.
2:38:16
I am so excited. Okay,
