Taggosyn, what is your meat base?
0:11
Meat
0:13
base? Protein, high protein tagline. You're already
0:16
hinting at what my tagline
0:18
was going to be. Oh. Hi everybody
0:20
and welcome to maintenance phase, the podcast that just wants to know
0:22
where you're getting your protein. Where are you getting your protein?
0:24
Aminos? Are you set for aminos? Are
0:27
you getting enough aminos? You
0:30
are a woman who lives in Portland and has a lot of vegans
0:32
and vegetarians in your life. Correct.

It's the same audio content
0:51
as Patreon. Some content. Patreon. My
0:53
quiet little repeating machine. I know. I
0:56
gotta keep, I keep trying to throw you off and it never works.
0:59
Uh,
1:00
today we're getting a little
1:02
time machine and we're going back to 2011. Yes.
1:05
Apparently. This is a
1:08
listener request. This is since
1:10
we did our
1:11
Super Size Me episode, this
1:14
is by far the most
1:16
requested like movie debunking
1:19
for us to do. Yes. Today we
1:21
are talking about Forks Over Knives,
1:24
which came out in 2011. And I think it was one one
1:26
of the first like streaming documentaries.
1:29
I think it was like when everybody was getting Netflix.
1:32
A huge number
1:33
of people watch this movie. The book based
1:36
on the movie was the number one New York Times bestseller.
1:38
Yeah, this comes from an era where there was a lot
1:40
of media about cord cutters.
1:42
Yeah, yeah, yeah, yeah. You wouldn't have cable anymore?
1:45
Imagine. So what do you know
1:47
about forks over knives, Aubrey?
1:49
What I remember its hypothesis as being
1:52
is that a vegan diet was healthier
1:54
and that it would lead to a longer life and that
1:56
it would prevent chronic
1:59
diseases.
2:00
and it was about
2:02
the origins of disease being
2:04
with eating meat and dairy. Yes.
2:08
Am I getting that right? Am I in the right neighborhood?
2:10
If anything, you're underselling it. Oh, wow.
2:12
This movie explicitly
2:14
says that a vegan diet will
2:17
prevent and reverse all
2:19
forms of chronic disease. Okay,
2:21
good. Heart disease, diabetes.
2:24
At one point, they mentioned dandruff. Halitosis.
2:28
Yeah. flatulence.
2:30
That's one thing I know that it won't solve. But
2:33
then okay, because this is a left-wing podcast,
2:35
I feel like we have to start with a series
2:37
of tedious disclaimers and meta
2:40
conversation about what we're going to do in this episode.
2:42
Let's do
2:42
it. Let's roll. I
2:45
really did go into this fresh. I
2:48
have never seen this movie. I have never
2:50
been a pro-vegetarian person,
2:55
but I've also never been like an anti-vegetarian
2:58
person. I have a lot of vegetarians and
3:01
vegans in my life. I've always
3:03
felt a spiritual kinship
3:06
with
3:06
vegetarians and vegans because the
3:08
stereotype of them is that they're constantly
3:11
lecturing you and they're announcing like, I'm
3:13
a vegan and you're not. I am sure
3:15
those people exist. I have never
3:17
come across anyone like that. Yeah,
3:20
I have known one preachy vegan
3:22
and it was just a preachy
3:24
guy who is vegan. Yeah, some people
3:27
tediously promote their own lifestyle and
3:29
some of those people are vegans and some of those people are not. It's
3:31
not clear to me that
3:33
that's a more common
3:35
trait among vegans than among non-vegans.
3:38
I will say this, I have experienced
3:40
infinitely more proselytizing
3:43
from keto and intermittent
3:45
fasting people. Although you're not a representative
3:47
sample because you do have a podcast where
3:49
you do say that those things are trash. Yes. Yes.
3:52
No, totally agreed. I'm not your starting
3:54
point for these conversations.
3:56
No, no, no, no. It is worth noting that like the animal
3:58
rights and climate.
4:00
change arguments for vegetarianism
4:02
are just fucking true. There's nothing to debunk.
4:05
It's like, yeah, the way that America treats animals
4:07
is atrocious. I'm not a vegetarian,
4:10
but it's totally indefensible,
4:12
the way that we treat animals. And also,
4:15
the climate and water
4:17
impacts of a meat-eating diet
4:20
are worse than a vegetarian vegan diet.
4:22
They just are. This also seems
4:24
like a good place for our standard
4:26
issue sort of reminder.
4:28
You should eat however you want to eat. We don't care.
4:31
Do what's right for you. We're gonna talk about a movie
4:34
and how this movie sells this
4:36
particular way of being and sort
4:38
of way of eating. But we're not talking
4:40
about the individuals who eat in that way,
4:42
nor are we
4:43
passing judgment on what anyone
4:45
else chooses or chooses not to
4:47
eat. Yeah, it's a very weird movie
4:49
because it is just a straightforwardly
4:52
a propaganda film. And most of
4:55
the factual claims in the movie do not hold up
4:57
to even the most cursory scrutiny,
4:59
but it's propaganda
5:01
in service of something that I think is good. Yeah,
5:04
yeah, yeah. Like I think vegetarian diets are fine.
5:07
And if you wanna be a vegetarian for literally any reason,
5:09
then you should do that. Yeah, that's right.
5:12
I actually really
5:12
appreciated this movie because first
5:14
of all, it does a lot of things that
5:16
I think are illustrative of the nature
5:19
of
5:19
how propaganda works and how
5:21
you can convince people of things without
5:24
technically lying, but just through
5:26
like selective
5:27
omission of important
5:29
context. And also, I
5:31
learned a lot watching this and debunking
5:33
this. Like I went down some really interesting rabbit
5:35
holes.
5:36
So mostly like we're just going to go through the movie and
5:38
I'm just going to tell you what I learned. It
5:41
feels really interesting to me because it's rare that you
5:43
and I both go into a topic pretty
5:46
fresh, like aware of the cultural
5:48
conversations around it. But like neither
5:50
one of us had seen this film. neither
5:53
one of us had done the deep dive into
5:55
sort of like health claims around
5:58
veganism and vegetarianism. Yeah.
6:00
I am like like you. I am not
6:02
a vegetarian, not a vegan, not plant based.
6:04
I like eat meat, but not very much.
6:07
Yeah, that's kind of where I am to. Wherever this lands.
6:09
Cool. Yeah. You know. So
6:12
let's kick ourselves
6:13
off by watching the first couple of minutes
6:16
of this movie, the opening montage.
6:18
I love this.
6:21
Clearly, the Western diet is taking a toll.
6:24
This should serve as a wake up call. We have a growing
6:26
problem. and the ones who are growing
6:28
are us.
6:31
Food. It's central to our
6:33
lives and traditions. Every
6:36
special occasion seems to involve food
6:39
and feasting. But could some of these
6:41
same foods, including several
6:43
that we think are good for our health, also
6:45
be causing many of our most serious health problems?
6:49
Indeed, we're facing a massive health
6:51
crisis. No
6:52
less than 40% of Americans today
6:55
are obese, and about half
6:57
of us are taking some form of prescription
6:59
drug.
7:01
This could be the
7:02
first generation of children in the United States
7:04
that lives less than its parents. We
7:07
spend 2.2 trillion dollars a
7:09
year on health care, over five
7:12
times more than the defense budget.
7:15
Yet we're sicker than ever. But
7:18
could there be a single solution to all of these
7:21
problems? A solution
7:23
so comprehensive, yet so straightforward,
7:26
that it's mind-boggling that more of us haven't
7:28
taken it seriously? Someone
7:30
has to stand up and say that the answer
7:33
isn't another pill. The answer
7:35
is spinach. A growing number
7:38
of researchers claim that if we eliminate or
7:40
greatly reduce refined, processed
7:43
and animal-based foods, we can prevent
7:45
and in certain cases even reverse
7:48
several of our worst diseases.
7:50
They say all we need to do is adopt
7:53
a whole foods plant-based diet. It
7:55
sounds almost too simple to be true.
8:02
This
8:02
is like the er example.
8:05
This is like the template for
8:08
fat people are killing us all. Right. You
8:11
can't tell from the audio, but this includes a lot
8:13
of footage of like headless fat people walking
8:15
around. I mean, it just, it really did feel
8:17
like, Oh, here we are in 2011. Yeah.
8:21
Like it just, it felt like the really
8:23
kind of shouty coverage that we
8:25
got about this stuff for a long time. Also,
8:28
a lot of maintenance phase cameos
8:31
in there. We get Richard Carmona, the
8:33
attorney general who started the
8:35
like terrorism is the threat from without
8:37
and obesity is the threat from within
8:40
the greatest
8:40
threat to our national security. We got Bill
8:42
Maher. Bill fucking Maher.
8:45
An authority on a diet
8:46
and lifestyle. The answer is spinach.
8:49
Take the stairs. We also got
8:51
two of these zombie statistics
8:53
that we debunked in that episode.
8:55
This is the first generation that won't live as
8:57
long as its parents playing the hits. And
8:59
then we also got at the end sort
9:02
of like the thesis statement of the movie, which
9:04
is basically what if a
9:06
plant based diet could
9:08
solve and reverse all of these issues?
9:11
So like I am not reading between the
9:13
lines or unfairly paraphrasing
9:16
when I say this, like this is this is the overt
9:18
thesis of this documentary. The other thing that
9:21
I was going to say about that intro, There
9:23
is this assumption that if you are
9:25
taking a drug,
9:27
you should not be taking a drug.
9:29
Yeah, I really don't like this stuff. There
9:31
are absolutely people who are taking drugs that
9:34
make their heart keep going, and
9:36
make their lungs take in air, and like
9:38
really basic biological functions.
9:41
And I mean, like, listen, there are drugs I take absolutely
9:44
every day that have absolutely helped me
9:46
stay alive at different points in my life. Yeah.
9:49
I don't think that that's like a moral failing
9:51
of mine,
9:52
that my brain chemistry looks
9:54
different than other people's brain chemistry. It's
9:56
also, it's in keeping with a weird
9:59
tendency Let's move it.
10:00
to like guild the lily, fruits
10:02
and vegetables are really good for you. People
10:04
should eat fruits and vegetables. That's totally fine.
10:06
But you don't need to say that eating
10:09
fruits and vegetables will reverse
10:12
your multiple sclerosis. We
10:14
then get a little like the history of food
10:17
section where it's like the same kind of stock footage
10:20
and we learn about like Betty Crocker and frozen
10:22
foods and all this kind of stuff. This
10:24
is familiar from like every other food documentary that
10:26
came out
10:27
around the same time where it's just like the rise of
10:29
processed foods and like people are
10:32
eating outside the home and people are joining the
10:34
workforce, blah, blah, blah. And then we
10:36
get to this
10:37
section where we
10:40
learn about the links between
10:43
animal proteins and cancer.
10:45
I'm going to send this to you. Send
10:48
this to me.
10:55
In the mid 1960s, Dr.
10:57
Campbell was in the Philippines trying to get
10:59
more protein to millions of malnourished
11:01
children. To keep costs
11:03
down, he and his colleagues decided
11:05
not to use animal-based protein. The
11:08
program was beginning to show success. But
11:11
then Dr. Campbell stumbled onto a piece of
11:13
information that was extremely important. It
11:16
centered on the more affluent families in the Philippines
11:20
who were eating relatively high amounts of animal-based
11:22
foods.
11:23
But at the same time, they
11:26
were the ones most likely to have the children
11:28
who were susceptible to getting liver cancer.
11:31
This was very unusual since liver cancers
11:33
are mainly found in adults. But
11:35
just the mere fact that they occurred in children
11:37
said, you know, there's something here. This
11:40
is pretty significant.
11:41
Shortly afterward, Dr. Campbell
11:43
came across a scientific paper published
11:45
in a little-known Indian Medical Journal. It
11:48
detailed work that had been done on a population
11:50
of experimental rats that were first
11:53
exposed to a carcinogen called Aflo-toxin,
11:56
then fed a diet of casein, the
11:58
main protein found in
12:00
They were testing the effect of protein
12:02
on the development of liver cancer. They used
12:04
two different levels of protein.
12:07
They used 20% of total calories
12:10
and then they used a much lower level, 5%. 20% turned
12:13
on cancer, 5% turned it off.
12:18
They love getting the shot of that Arby's
12:21
sign. I know. I've been to that Arby's.
12:23
I mean, I haven't been to it, but I've been by
12:25
that Arby's. You can tell they're going back to the history
12:28
of food stuff.
12:28
Boy, they really are. Americans discovered Arby's.
12:31
Okay, so I will say on
12:33
the face of this, I'm sure that you're gonna be like, this
12:36
never happened and this paper was never
12:38
written or something like that. But
12:41
what I will say is just like on the face
12:43
of it, I find it really fascinating
12:45
that the presumption that
12:48
because this particular
12:51
health phenomenon existed within
12:53
children of affluent people, that
12:56
like the first place that they went to
12:58
was diet to explain it. It's
13:01
really odd to just be like, it
13:03
has to be their diet and it's got to
13:05
be the meat. Like what? One thing this documentary
13:08
does and a lot of documentaries do is
13:10
they bombard you with a lot
13:12
of information very quickly. And at
13:14
the end of it, you're left with this impression,
13:17
right, of like, OK, wealthy kids in the
13:19
Philippines getting liver cancer. We looked
13:22
into it. Apparently it was the animal proteins
13:24
giving them cancer. Right. This is the same kind
13:26
of science communications that's in like the
13:28
fucking Zoloft bubble commercials
13:31
where they're like one side of your brain produces
13:34
the happy chemicals and then the other side
13:36
with the brownie face can't accept them.
13:38
Right. This
13:41
is a science communications
13:44
that assumes you don't really
13:45
need to know what's actually happening
13:48
here. Right. The best science communications
13:50
invites you to consider the complexity
13:53
of the world and the worst invites
13:55
you to ignore the complexity.
13:57
Mm-hmm. So the paper
13:59
that he's talking about. It's a study on
14:02
rats' susceptibility to
14:04
this toxin, aflatoxin.
14:06
It's a mold that grows on corn
14:09
and peanuts. And so this was a
14:11
real problem in a lot of countries
14:13
for a long time. In humid environments, this
14:16
mold grows. When you harvest
14:18
the crops, you also harvest the mold,
14:20
and kids end up eating this toxin.
14:23
And yes, kids get liver cancer. Kids get
14:25
all kinds of really awful effects of
14:27
this toxin from eating mostly peanuts
14:29
but also corn especially in the developing world. What
14:32
they're doing is they're not looking
14:34
at whether milk
14:36
protein causes cancer in
14:38
rats. They're exposing
14:41
rats to this carcinogen, to huge
14:44
doses of this carcinogen. And
14:47
then some of them are like little vegan rats. Some
14:49
of them are not vegan rats. you're
14:51
like, oh, the non-vegan rats got
14:53
tumors, which is true. But
14:56
it's like this is a specific
14:58
effect of the toxin they're being given.
15:00
This isn't just like rats existing in the world
15:03
and the little vegan rats don't get cancer.
15:06
It's not the same thing as a human child.
15:08
And it's not the same thing as eating corn
15:11
once a week. Right. If you want, even if you wanted
15:13
to do this study in rats, the rat answer
15:15
would be, Hey man, feed him some
15:17
of that corn every once in a while. So,
15:19
okay. let's do still have the clip up. Let's
15:22
go to 1637 together. There we go. 37. Bing, bang,
15:26
boom.
15:27
So this is the text
15:29
that they show on screen when
15:31
they're describing this study. So
15:34
toward the bottom, read
15:36
the sentence that starts with in all. In
15:39
all, 30 rats on the high protein
15:41
diet and 12 on the low protein
15:43
diet survived for more than a year.
15:45
Low protein here means
15:46
vegan, basically. Or like this is the
15:49
analog that they're inviting us to consider.
15:51
So wait, what the fuck? Yeah, yeah.
15:53
More of the high protein diet rats
15:55
survived? So the vegan rats
15:59
were twice as l-
16:00
likely to die. They had to stop
16:02
the study because the little vegan
16:05
rats kept dying. So it's
16:07
not useful for understanding humans
16:09
and also it says the opposite
16:11
of what they said was going to say.
16:14
Exactly. I feel like this is my new way of documentaries
16:16
is just pause on
16:19
every block of text
16:21
and be like, hang the fuck on, we're reading
16:23
this entire thing. So when they
16:25
talk about this
16:26
obscure study published in Indian
16:28
Journal, the study is part of a two-part
16:30
study. One of the studies, which is what
16:32
they're referring to here, is about the growth
16:35
of tumors in
16:36
the rats. The other study is
16:38
about why the rats kept fucking dying
16:40
and the vegan rats were
16:43
much more likely to die. So
16:46
I'm not going to say that this invalidates
16:48
vegan diets. That would also
16:50
be just as superficial as saying this proves
16:52
vegan diets. But like, okay, if
16:54
it's turning off cancer but you're more likely to
16:57
die, then the cancer thing's kind of
16:59
irrelevant, right? Like we only care about cancer
17:01
to the extent that it's killing people. I
17:04
love that a documentary would have this
17:06
level of a self-own in it that if
17:08
you pause
17:08
it, it undoes its own work.
17:11
It undermines itself if you
17:14
read all of the text on screen. Okay,
17:16
so then we get to the
17:19
other protagonist of this documentary. So this
17:21
documentary basically follows these two
17:23
doctors. One is T. Colin Campbell.
17:26
That was the guy who we just met in the Philippines.
17:28
And the other one is named Caldwell Esselstyn.
17:31
And he is telling us
17:33
about his work as a surgeon
17:35
and how that led him to
17:37
do his own research. So
17:40
Dr. Esselstyn started investigating the global
17:42
statistics on breast cancer.
17:45
One of the facts he discovered was that the incidence
17:47
of breast cancer in Kenya was far lower
17:49
than than it was in the United States.
17:52
In fact,
17:53
in 1978, the chances
17:55
of a woman getting breast cancer in Kenya were 82
17:58
times lower than in the U.S.
18:02
Dr.
18:02
Esselstyn was even more surprised by
18:05
the numbers he discovered for some other types of
18:07
cancer. In the entire nation
18:10
of Japan in 1958, how
18:12
many autopsy proven deaths were
18:15
there from cancer of the prostate?
18:20
In the same year, the U.S. population
18:22
was only about twice the size of Japan's,
18:25
yet that the number of prostate cancer
18:27
deaths exceeded 14,000. Dr.
18:31
Esselstyn also discovered that in the early
18:33
1970s, the risk
18:35
for heart disease in rural China was 12
18:38
times lower than it was in the US. And
18:41
in the highlands of Papau, New Guinea, heart
18:43
disease was rarely encountered. Even
18:46
more compelling to Esselstyn was some historical
18:48
data that had long been overlooked.
18:50
In World War II, the Germans occupied
18:52
Norway. Among the
18:55
first things they did was confiscate all
18:57
the livestock and farm animals to provide
18:59
supplies for their own troops. So
19:02
the Norwegians were forced to eat mainly plant-based
19:04
foods. Now
19:06
we look at the deaths in
19:09
Norway. Just antecedent to this period
19:11
from heart attack and stroke. Look right up here,
19:13
right at the very top, 1939.
19:16
Bingo! In come
19:18
the Germans. Well hang on. Really? 1940s.
19:22
Wow. Have
19:25
we ever seen a population have their
19:27
cardiovascular disease plummet like this from
19:30
statins? I know. But
19:32
look what immediately happened
19:34
with the cessation of hostilities in 1945.
19:38
Back comes the meat, back comes the dairy,
19:41
back comes the strokes and heart attacks.
19:44
Uh-uh. Okay. Okay.
19:47
Holy shit. Describe the visual
19:49
feast that we just had in the last like 30 seconds
19:52
of it.
19:53
Holy shit, Michael. But
19:56
first I will say, while we were watching this clip,
19:58
I was like, oh, we're in peace.
20:00
Michael Hobbs territory. Yeah.
20:02
Why are people dying of this thing
20:04
in this country, but not in this country is
20:07
like prime grade. Oh,
20:10
I'm using meat metaphors. Yes. Spurious
20:12
correlations are the filet of this documentary.
20:15
Then we get a graphic
20:17
that is one of the wildest
20:19
things I have ever fucking seen
20:21
in my life. You go to 2050. Holy.
20:25
See the chart in all of its glory. I
20:29
know. This
20:31
is like Monty Python. Yeah.
20:34
Yeah. So the title of the graph is Mortality
20:36
from Circulatory Diseases, Norway,
20:40
1927 to 1948. And
20:44
what it shows is more
20:46
people dying of heart disease.
20:47
That peaks
20:49
at about 1940, and they have
20:51
superimposed a little
20:54
teeny, tiny Nazi flag. And it pops
20:56
in like pop
20:57
up video. It's like, boop.
21:00
That's it. It goes. Yeah,
21:03
great. Good. And
21:06
then mortality from circulatory
21:08
diseases, plummets. You
21:10
got to hand it to them. Listen, if you were
21:13
just looking at this
21:14
graphic without the narrative
21:17
that is offered by the documentary,
21:20
it really looks like it's trying
21:22
to credit Nazis with
21:24
like the heart health of Norway.
21:27
I posted this on Twitter and people were like, this seems unfair
21:29
that you're posting this out of context. And
21:32
I was like, it is not better in context. This
21:34
is like yet another reason
21:36
that it's good that I'm not on Twitter very often.
21:39
People were yelling at me and I was like, I cannot debunk
21:41
this for you because Aubrey might see
21:44
it. So just open your podcast app
21:46
in like two weeks. Chill out. We'll
21:48
be back in a minute. So obviously all
21:50
of these country comparisons are extremely
21:53
facile. So the first thing he points
21:55
out is that Kenya had a much lower
21:57
rate of breast cancer. than
22:00
America in the 1970s. Jesus
22:02
Christ. Obviously, the reason why you have
22:04
less breast cancer in Kenya at the time is because Kenya
22:07
does not have a healthcare
22:09
system that is set up to do breast cancer screenings.
22:12
And also, the rates of infectious diseases are
22:14
significantly higher in Kenya. So
22:17
people are not dying
22:18
of non-communicable diseases because they
22:20
have more urgent issues that they're dealing with.
22:23
We then go to the extremely
22:25
low rate of prostate cancer deaths
22:27
in Japan, where
22:29
I look this up. It
22:32
appears to be the case that prostate cancer
22:34
rates are lower in Japan. It's
22:36
genuinely like kind of a mystery. What
22:39
frustrates me about this documentary is that it's actually kind
22:41
of interesting. It seems to be more
22:43
related to the fact that a lot more
22:46
Americans get a surgical procedure
22:48
called a TURP. What? where
22:50
they go up through your urethra
22:53
and
22:53
cut a little chunk out of your prostate.
22:56
And as part of this procedure, they usually do a biopsy
22:59
on your prostate tissue. Oh, so we're just
23:01
checking way the fuck more often?
23:04
Yeah, basically, like that is
23:06
the most obvious explanation. There's
23:08
just a lot more screening for prostate
23:10
cancer, especially in 1958, which is the year that
23:13
he refers to here. Right. This
23:15
feels reminiscent to me of that 60 Minutes clip
23:18
about red wine. Yeah, yeah, yeah. Well,
23:20
hang on guys, there might be a story
23:22
here, but you got to adjust for all this other
23:25
stuff first. Right.
23:26
He then takes us to rural
23:29
China and Papua New Guinea and
23:32
says that their rates of heart disease are much lower
23:34
than the US. And again, this is true.
23:36
They also at this time have 12 year
23:39
shorter life expectancies. Jesus hell.
23:41
Mao dies in 1976. China is coming out of one of the
23:44
the most brutal, decades-long,
23:47
repressive periods of any country in history.
23:50
It's just very weird to make this comparison
23:51
and talk about China as some
23:53
sort of utopia of better dietary
23:56
choices. All of this also plays
23:58
into some narratives. that
24:00
are culturally really tempting
24:02
to a lot of Americans, right? One of them
24:04
is one that we've talked about before. It's in
24:07
a book called Diet and the Disease
24:09
of Civilization. Which is sort
24:11
of this belief that our diet
24:13
is evidence that we are part of a fallen
24:16
society. Right. When these
24:18
narratives go in a direction that your
24:20
brain was already headed, when they
24:22
tell you things that you were already kind
24:24
of thinking, those are points that are
24:26
more likely to land for you. Right. Right.
24:29
That takes
24:30
us to Norway and the Nazis.
24:32
Tell me about Norway and the Nazis, Jesus Christ.
24:35
I thought this was like super interesting. It
24:38
is true that the Nazis occupied
24:40
Norway and like confiscated everybody's
24:42
livestock and immediately imposed
24:45
like really strict rationing regimes.
24:47
People were so desperate for food that they were like growing
24:49
food in their backyards. A lot more people started
24:51
fishing, just like get food
24:54
from the wild. People were like eating moss and shit.
24:56
It is true that the dietary patterns
24:58
of Norwegians change very significantly
25:00
and very rapidly during this period. What
25:03
the documentary doesn't mention though is
25:05
what the war did to infectious
25:08
disease. There is a researcher
25:10
named Broda Barnes who wrote a book
25:11
called Solved, The Riddle of Heart
25:14
Attacks. He is looking
25:16
at this period after World War II, all
25:19
over Europe, you have rapidly rising
25:21
living standards. are getting back
25:24
to normal and they're rebuilding infrastructure,
25:26
employment is really high, they're setting up
25:28
these healthcare systems, setting up welfare systems
25:30
for the first time. At the same time,
25:33
you have an explosion
25:33
of heart attacks. Right.
25:36
And so it's like, well, people are doing everything you're supposed
25:38
to do. They have healthy diets,
25:41
much better living standards, and yet heart
25:43
attacks are going up. He starts looking
25:45
at autopsy data from people
25:47
in Graz, Austria, and
25:50
he finds the same pattern they found in Norway where
25:52
there's this huge reduction in heart attacks and
25:55
then a massive increase. This isn't
25:57
all of the explanation, but the primary
25:59
explanation for this effect is tuberculosis.
26:02
What? Having blocked arteries makes you
26:05
susceptible to tuberculosis, and
26:07
it makes you susceptible to heart attacks. It
26:09
increases your risk of both of them. Before
26:12
the war, most people would
26:14
just die of tuberculosis. If
26:16
you had blocked arteries, you get tuberculosis,
26:18
you end up dying of tuberculosis, you don't live
26:20
long enough to have a heart attack. After
26:23
the war, you get treatments for tuberculosis.
26:25
So when you get tuberculosis, you get antibiotics,
26:28
and then your tuberculosis goes away, you live a couple more
26:30
years, and then you die of a heart attack because you have all these
26:32
risk factors. Well, this is also something
26:35
that has come up on the show before that
26:37
you have mentioned, which is essentially like
26:40
how technologies and treatments
26:42
are changing around these conditions, right?
26:45
So like, we are still talking
26:47
about heart disease in sort
26:49
of the way we did in the like 80s and
26:52
90s, and treatments for heart disease
26:55
and mortality rates and all of that kind
26:57
of stuff look really different now
26:59
than they did 30 or 40 years ago.
27:02
Well, what I'm so fascinated by is without
27:04
any
27:04
context, you look at
27:07
Europe after World War II and you're like, holy shit, the heart
27:09
attacks are going crazy. Like this
27:11
is really worrying, but actually it's good
27:14
news, right? Because almost every single one
27:16
of those people would have died of tuberculosis.
27:19
What that's actually reflecting
27:21
is a precipitous drop in tuberculosis
27:23
deaths. or what it looks like from the outside,
27:26
or if you only look at this one metric, you're
27:28
like, oh my God, we're getting so much less healthier. You know, it's
27:31
interesting as we're talking about this, I'm realizing how
27:33
many mortality numbers are just completely
27:36
and totally decontextualized. Totally, I
27:38
know, this like fucked with my brain too, yeah. The
27:40
main way that I feel
27:42
like I encounter mortality numbers
27:45
in the wild is not unlike this
27:47
documentary where it's just like big
27:49
block letters of a big scary number
27:51
in the web, but it's not
27:54
stacked up next to. Here are some other
27:57
similar levels of mortality
27:58
causers. Like, they're
28:00
not giving you anything to relate it to, they're
28:02
just saying big numbers
28:05
at you and the big numbers sound scary. This
28:07
takes us back
28:08
to Norway. So what we
28:10
find when you look into the actual specifics of
28:12
Norway and you're not just trying to make a point with
28:14
a graphic or whatever, is that tuberculosis
28:17
and other infectious diseases exploded
28:20
in Norway during World War II. So
28:22
this is from a paper about this. It says, the
28:25
incidence of infectious diseases increased substantially
28:27
during World War II Norway probably
28:29
due to the introduction of infectious agents
28:32
from the large contingent of German soldiers
28:34
and civilians up to 450,000 and in addition 100,000
28:35
prisoners of war from Eastern
28:40
Europe. So basically, a
28:42
huge influx of people into Norway.
28:45
Some of those people are carrying tuberculosis and
28:47
other infectious diseases.
28:49
And so heart attacks go down because
28:51
people are dying of other things first.
28:54
You know, they're getting pneumonia, they're getting various other things.
28:57
is one of the main causes. And there is
28:59
actually a big outbreak of tuberculosis in Oslo
29:01
during World War II. But just kind of overall,
29:04
people are just dying of other stuff.
29:07
So just like a rise in
29:09
heart attacks isn't necessarily bad
29:11
news. A drop in heart attacks isn't necessarily
29:14
good news. I think, again, particularly after
29:16
having done a couple of years of this show,
29:18
I now feel so
29:21
suspect when I see this kind of decontextualized
29:23
reporting. one weird
29:26
trick and then the graph goes down
29:28
and you're like, what? Yeah, this I'm,
29:30
I'm way
29:31
too like mortality pilled
29:33
to watch documentaries like this. I
29:35
was like watching it and I was like, it just has the
29:37
structure of something that's wrong.
29:40
Right. Like anytime you're like World
29:42
War Two and then the heart attacks fell. I'm like, I
29:44
don't think I think someone's probably written a PhD
29:47
about this and it's probably significantly more
29:49
complex. Yeah, this is the reaction
29:51
that I started to have early on when we were doing the
29:53
show to headlines with a question
29:55
mark in it. Yeah, yeah, yeah. I'm onto you. We're
29:58
not doing this. So church.
30:00
When we turn to the film, we then go from
30:02
Nazis to protein. Yeah, the classic
30:04
progression. There's a whole thing, they do more
30:07
stuff about how animal proteins cause cancer,
30:09
but it's all this aflatoxin shit. They
30:12
do mention very briefly, and I don't
30:14
know why they don't linger on this more,
30:17
that vegetarian diets do not mean that you're going
30:19
to get a protein deficiency. The whole thing
30:21
of you need
30:22
all this protein to survive is basically
30:24
just a decades-long propaganda campaign
30:27
by the meat industry.
30:30
feels a little bit similar to the fiber stuff.
30:32
It's similar to vitamin C stuff where we're
30:34
like really bad at knowing what things
30:36
have protein in them. Yeah. Yeah. Yeah. Yeah. Plenty
30:39
of vegetables, plenty of
30:41
beans, plenty of like, generally
30:44
speaking, Americans eat much more protein
30:47
than any sort of nutritional guidelines
30:49
suggest that we might
30:51
need. Also, there's dozens of studies on this. One
30:53
of the ones that I found non vegetarians
30:56
are getting roughly double the amount of
30:58
daily recommended protein and vegans
31:01
are getting one and a half times the
31:03
recommended amount of protein.
31:05
For non-vegans,
31:08
we're getting 15 to 17% of
31:11
our calories from protein
31:12
and vegans are getting It's
31:14
not that big of a difference.
31:17
I should say that those surveys are based
31:20
on the same dumb food frequency
31:22
questionnaires that we're always criticizing in other diet
31:25
studies. I don't believe
31:27
biblically in these numbers, but also one
31:30
of the main problems with these food frequency
31:32
questionnaires
31:32
is that people underestimate how much
31:34
they're eating. If people are saying
31:37
that this is how much protein they're getting, they're
31:40
probably getting even more. Even
31:43
if you
31:43
throw out the food frequency questionnaire stuff,
31:45
which is totally legitimate, protein
31:48
deficiencies are just not
31:50
a problem in the United States. People are not going
31:53
to the hospital with protein deficiencies.
31:55
I'm guessing there are a problem in as much as
31:57
hunger overall is a problem. This
32:00
is what you find in the study. So I found a study
32:02
that is finally just like laying it out
32:04
like brass tacks. It says, there
32:07
is a widespread myth that we have to
32:09
be careful about what we eat so that
32:10
we don't cause protein deficiency. We
32:13
know today that it's virtually impossible
32:15
to design a calorie-sufficient diet
32:17
which is lacking in protein and any of
32:19
the amino acids. So basically, when
32:22
you look at actual protein deficiency cases,
32:24
it's
32:24
almost always people with very
32:26
rough eating disorders who just are
32:28
not getting enough food overall. You
32:31
would legitimately have to try
32:33
to design a diet that has enough
32:35
calories but doesn't have enough protein.
32:38
So unless you're doing this for a fucking YouTube challenge
32:40
or something, you're probably fine.
32:43
My understanding is that this is the case on a
32:45
number of nutrients. You don't need
32:47
to worry about how much riboflavin
32:49
you're getting. The only
32:51
exception I found was that if you're an elite athlete,
32:54
it turns out you can need more protein or
32:56
whatever, but you know that if you're an elite
32:59
athlete. It's not like you're
33:01
learning this from an internet listicle
33:03
for the first time, and the vast
33:04
majority of the population is not
33:07
an elite athlete with very specific
33:09
macronutrient needs.
33:10
Michael Phelps isn't listening to this episode
33:13
going like, oh, interesting, more protein. All
33:15
right. First time I heard this. Good
33:17
to know.
33:18
get a clip
33:21
about the ability of a vegan
33:23
diet to reverse heart
33:25
disease. Okay,
33:28
let's go. I'm going to send you
33:30
a clip.
33:33
Dr. Esselstyn was getting some powerful data
33:35
from the research he'd started in 1985. He
33:39
began with 24 patients,
33:42
but six had dropped out in the first year,
33:44
leaving him with a total of 18. The
33:47
end of five years we had to follow
33:49
up angiograms and 11 of the group unhauled
33:52
their disease. There was no progression
33:54
and there were four where we had
33:56
rather exciting evidence of regression
33:59
of disease.
34:00
These results were astonishing. The
34:03
diet produced something that medication and
34:05
surgery never had before. Actual
34:08
reversals of heart disease.
34:11
They're again making some like very
34:14
bold claims. The underlying
34:17
logic is like you're basically immortal. Right.
34:20
You will die of old age at, you
34:22
know, 90 something or 100 and something
34:25
because nothing's taken you down. He's
34:27
also papering over some
34:30
fairly weird number stuff. Yeah,
34:32
four cases. Yeah. This study
34:35
that he's talking about, he does eventually publish
34:37
it. I'm getting a lot of this
34:38
from a woman named Denise Minger, who is
34:41
one of the only people to take this movie
34:43
seriously and try to debunk it. So
34:46
she points out that
34:47
there's no control group. It's
34:50
self-selected. People are going to
34:52
this guy who's at this point a very prominent
34:54
vegan advocate. This is basically just
34:56
an anecdote,
34:57
ultimately. Even though it's published, it's
34:59
basically published as like a case study. It's not
35:01
like a randomized control trial or anything. I
35:03
can't really debunk that, but it's not clear
35:05
that this really says anything about vegan
35:07
diets overall.
35:08
But what's
35:10
really interesting is that there are actually studies
35:13
where these kinds of interventions have reversed
35:16
heart disease. So one
35:18
of the
35:18
most famous ones is, do you know Dean
35:21
Ornish? Sure, the Ornish diet
35:23
for sure. The Ornish diet. My mom was
35:24
on that for years. This was like a huge presence
35:26
in our house growing up. Very big, very popular in
35:29
the 80s. Yes. He's basically like the
35:31
patron saint of low-fat diets.
35:34
This was the guy telling you to eat carrot
35:36
sticks. This is why your parents were doing that in the
35:38
80s. He has a study that
35:41
shows people actually
35:43
reversing symptoms of heart disease.
35:45
And so this is touted as evidence that
35:49
a low-fat vegetarian diet
35:50
reverses heart disease. However, if
35:53
you read the actual study, It's not
35:55
just a low-fat vegetarian diet.
35:58
This is a program where people are also
36:00
quitting smoking. They're also getting
36:03
stress management training and
36:05
they're also increasing their exercise, getting
36:07
daily exercise. Oh, so it's like
36:09
a full overhaul on how you were
36:11
being in the world is now very
36:14
different than how it was before. That's a
36:16
lot more than just eating less fat in
36:18
your diet. Also, after you have
36:21
a heart attack or a stroke scare,
36:24
usually you're extremely
36:25
motivated to change your lifestyle.
36:28
So a lot of these things work for like a year
36:30
or two, because people are like, holy shit, I'm going to die.
36:32
And then they do like all this stuff at once. So
36:35
that doesn't mean that like a low fat vegetarian
36:37
diet doesn't reverse heart disease, but
36:40
it's like,
36:40
we're doing 10 things at the same time. I
36:42
would also say like, in that year
36:45
or two, after,
36:47
you know, a cardiac event, or after
36:50
a new diagnosis, or whatever, you
36:52
are extremely motivated to make a bunch of lifestyle
36:54
changes, but you were also
36:57
on a more intensive schedule
36:59
of health care. Oh yeah.
37:00
There's like numerous scenes in this
37:03
documentary where they talk about how these like these vegan
37:05
doctors are like, we're not like other doctors. And there's
37:07
a scene where a doctor goes with
37:09
one of his patients to the grocery store
37:11
and like helps him shop for stuff and
37:13
is like giving him recipes and like having him over
37:16
for dinner, it appears. So it
37:18
might not be the veganism. It might be that
37:20
like your
37:20
doctor really gives a shit about you. I would
37:22
say also on this this reversal stuff is like just
37:24
because it's possible for some
37:27
people doesn't mean
37:29
that it is likely for
37:32
everyone or possible for everyone
37:34
or guaranteed for everyone. But
37:37
like the way that this kind of stuff
37:39
comes across and the way that it is pitched
37:42
is this is a sure shot. All
37:44
of those caveats, which are all
37:47
context, are all missing,
37:49
right? I also think it's important to note that like
37:52
it may be the case that vegan diets can help
37:54
people reverse heart disease, but that's not the only
37:57
diet that has been shown to do that. So
37:59
there's studies. the Mediterranean diet that have shown
38:01
that. There are studies of low-fat diets. There are studies
38:03
of low-carb diets. There's a
38:06
study of a high-fiber diet. One
38:08
of the most interesting things I found was one of the studies
38:11
showed that people tend
38:14
to stick with a vegetarian diet
38:16
longer when they're doing these programs because obviously
38:18
the initial burst tends
38:20
to go away after a year or two. One
38:23
of the reasons why vegetarian diets might
38:26
be good for managing things like diabetes
38:28
and heart disease could just be that people
38:30
find it much easier to stick to over the long
38:32
term because like vegetarian
38:34
diets are like fairly entrenched in
38:37
our lives. Like you can go to a restaurant and be like,
38:39
Oh, Hey, what do you have on the menu? That's vegetarian. Yeah.
38:42
Whereas if you're on like the Mediterranean diet
38:45
or I'm low carb, there's just
38:47
a bit more friction. I will
38:49
say I think the it's easier
38:51
to be vegetarian. Take is
38:53
a very coastal city dweller take
38:57
in part because this is
38:59
one of my favorites. A good friend
39:02
of mine is vegetarian and works in
39:04
politics in Montana and ends up at
39:06
a bunch of fundraising dinners. She
39:08
will ask for the vegetarian
39:10
option at said fundraising dinner and will
39:12
be given chicken.
39:13
Oh, yeah, that's vegetarian for Montana.
39:16
Yeah, it's a bird. You're
39:18
welcome. Yeah, this used to happen when I lived in Germany
39:21
a lot, too, that my American friends would be like, what are
39:23
your vegetarian options? And they'd be like veal.
39:26
It's like,
39:27
no, I think the baby animals are still animals.
39:30
And then, okay, so after this,
39:33
we then get one of the weirdest
39:35
clips of the entire movie. So
39:38
they're catching up with people who
39:40
were in this heart disease
39:42
study. And so we're doing like a follow-up
39:45
with one of the patients and the benefits in their lives.
39:48
Anthony and the other male patients also
39:50
noted another change. When you're young,
39:53
when you're a teenager, you see a
39:56
female and so on. It gets kind
39:58
of exciting. And
40:00
the first reaction physically, you
40:02
know, it gives attention,
40:05
you know, raise the flag, I call it.
40:07
This happened to us. All the other
40:11
Dr. Enserson's, I call him
40:13
all the guinea pigs.
40:15
The flag still rises.
40:17
What? So
40:21
now we're just talking about dicks. So
40:23
this dude gets boners. We're talking
40:26
about this dude and his boner. God damn
40:28
it. He's talking about raising his
40:30
flag. Very patriotic. I
40:33
was all ready to debunk this.
40:36
The thing about a vegan
40:38
diet reversing your erectile dysfunction
40:40
is obviously not supported by the
40:42
data. However, erectile
40:44
dysfunction is a precursor
40:47
of heart disease. And so it's now
40:49
becoming a thing that
40:51
they actually tell patients that if you're middle aged
40:54
and you start getting erectile dysfunction and there's no kind
40:56
of obvious reason for it, then
40:59
you should go get your heart checked out because
41:01
it's like your artery's closing and it's something. Right, it's
41:03
like a blood flow issue. Yeah. Yeah. This
41:05
is a thing to look out for. If you're not raising flags.
41:08
Don't. Raise more flags. So
41:11
that's basically the end of the documentary. We're
41:14
only two thirds of the way into the documentary
41:16
at this point, but the rest of the documentary is
41:18
just a bunch of stuff that
41:20
is true, but kind of irrelevant. So,
41:24
there's a long sequence with like an
41:27
MMA fighter and he's like, it's possible
41:29
to be an athlete and a vegan. And like, yeah, yes,
41:32
it is. Okay. There's
41:34
a whole section about how school lunches suck. Like
41:37
yeah, that's true. There's
41:39
a very baffling part where he talks
41:41
about like milk being bad for you
41:43
and like milk is poison. And
41:45
then
41:46
there's a really funny chart where they
41:49
point out that the countries with the highest
41:51
milk consumption in the world have
41:53
the highest rates of hip fractures, which
41:56
is a sign of osteoporosis. What? So
41:59
it turns out milk...
42:00
doesn't actually make your bones stronger. This
42:02
is some fucking Pete Evans shit. Yeah.
42:05
Dairy leeches calcium from your bones
42:07
was his thing, I believe. I
42:09
love this as like a
42:10
spurious correlation because all
42:12
of the countries that have the highest milk
42:14
consumption, they're all Scandinavian countries.
42:16
And most of the countries with the lowest
42:19
milk consumption are like tropical countries
42:21
in like Southeast Asia. In debunking this
42:23
movie, people point out that all
42:25
of the countries with high milk consumption
42:28
have very cold winters.
42:30
And one of the main reasons why people fracture
42:32
their hips is falling on the ice.
42:35
So you just in Thailand
42:37
have a lot fewer hip fractures than you
42:39
do in Norway, which has nothing
42:42
to do with milk consumption. It's just like there's
42:44
a reason people fall down in
42:46
Scandinavia. So then
42:49
the worst,
42:50
by far the worst section of
42:53
this movie is there's a lady who's a marathon
42:55
runner, and then she's diagnosed with breast
42:57
cancer. They're like, oh, she was
42:59
told to get radiation and chemotherapy, but instead
43:02
she went on a vegan diet.
43:05
And now she's like running Iron Mans. Right.
43:07
We're back in sort of Gerson therapy
43:10
adjacent territory. Yeah. Like
43:12
this was where, I mean, not that I had a lot of
43:14
confidence in this documentary, but I was like, this is
43:17
really irresponsible. Yeah. Vegan diets
43:19
are fine, but don't tell people that they fucking
43:21
cure cancer. What the fuck is wrong with you? I mean,
43:23
I feel, I would say I feel sort of shades
43:26
of gray that way about
43:28
most dietary interventions
43:30
into most health conditions, right?
43:33
If someone is telling you
43:35
and is not presenting pretty hard
43:38
and fast data that like X,
43:40
Y, or Z dietary change means
43:42
that you cease to have a chronic
43:45
health condition. All of this
43:47
shit just needs
43:47
to be tempered and presented in context
43:51
in order for us to understand it properly. But
43:53
then this gets
43:54
us to what I want to spend the rest of the episode
43:56
on, which is the years long
43:59
debate. about whether a vegetarian
44:01
diet is good for you. Oh, just full
44:04
stop. Just like, is it healthy? Period.
44:07
Are you healthier eating a vegetarian
44:09
diet than not eating a vegetarian
44:11
diet? This is the core claim of this movie.
44:13
Let's do it. So to talk about this,
44:16
we have to talk about vitamin E. Okay.
44:19
Vitamin E is a now notorious
44:22
antioxidant. In the sixties
44:24
and seventies, there were a bunch of mouse studies show
44:27
that this helped oxidate
44:29
the bloodstream and could reduce
44:31
plaque in their little mouse hearts. After
44:35
this very
44:36
preliminary hypothesis
44:39
generating stuff on animals, people
44:41
start doing these observational studies on humans.
44:44
Vitamin E is found in like sunflower
44:47
oil and almonds and peanut butter and all kinds
44:49
of stuff and so they start doing these big
44:51
cohort studies where they ask people
44:54
what their diet is and what kind of health markers
44:56
they have, how early they're dying, et cetera.
44:58
And so again and again, studies
45:00
are finding that people who consume more
45:02
vitamin E like live way longer.
45:05
This is starting to look pretty strong in
45:07
the 1990s, right? It's like, well, it's
45:09
happening in animals, it's happening in people,
45:12
so we should probably start giving people supplements
45:14
for vitamin E, right? So in the 1990s
45:17
and 2000s, doctors start
45:19
giving vitamin E supplements to patients, especially patients
45:22
who have had some sort of cardiac event. So people
45:24
who are recovering from heart attacks start getting vitamin
45:26
E supplements. So the daily
45:29
recommended amount of vitamin E
45:31
is 22 international units. And
45:34
doctors start giving patients either 400
45:36
or 800 international units. Holy
45:40
shit! 20 to 40 times
45:43
the daily amount. Jesus. And
45:45
so after this wave of animal studies,
45:48
after this wave of observational studies, we start getting
45:51
randomized controlled trials of people who are
45:53
taking vitamin E and people who aren't taking vitamin E.
45:56
And it turns out that vitamin
45:58
E has no effect on vitamin
46:00
And for some people, vitamin E
46:02
actually increases the risk of heart
46:04
attacks. These are not large effects,
46:06
but people who take large doses
46:09
of vitamin E are 13% more likely
46:11
to have heart failure in one study. Oh, wow.
46:13
So there's now been this huge
46:15
turnaround on vitamin E, and the
46:17
entire field is like, oh, fuck, we
46:20
really got this one wrong. We're basically giving people
46:22
large doses of this thing
46:25
that there really is no evidence for
46:27
at this point. Yeah.
46:28
So, people have now gone back and
46:30
have done this sort of like, what
46:32
happened? Like, how did this whole
46:34
catastrophe take place with
46:36
vitamin E? And what they've
46:38
identified is something called healthy
46:40
user bias. In all of those
46:43
observational studies,
46:44
the people who were getting more vitamin E, or
46:47
people who were eating more almonds, eating more
46:49
vegetables, they're getting more
46:52
fiber, they're basically eating like a
46:54
better diet and those foods happen
46:56
to have vitamin E,
46:58
but it wasn't the vitamin E that was making those
47:00
people healthier. It was all of the other
47:02
shit that they were doing. Yeah, which also probably
47:05
correlates to higher
47:07
socioeconomic
47:08
status. It also probably
47:10
correlates to not
47:12
having other disabilities is my
47:14
guess. Yes. I mean, I think about this often
47:17
with celery juice too, right? Like if
47:19
you're a person who can afford a juicer
47:22
and has the time in the
47:24
morning
47:24
to juice 16
47:27
ounces of celery and
47:29
drink it and then wait a half an hour before
47:31
you eat anything else. There's
47:34
all this other stuff that's sort of loaded into
47:36
that. It's not just a matter of
47:38
like, oh, any person who
47:41
drinks the celery juice will have this effect
47:43
or whatever. This form of
47:45
bias is a huge
47:47
existential problem in these kinds of
47:49
studies. One of the large
47:52
effects that I found in other
47:54
various meta-analyses is that people
47:56
who brush their teeth regularly, have 30%
47:58
lower more. than
48:00
people who don't brush their teeth. What that's covering
48:03
is not necessarily that brushing your teeth extends
48:06
your lifespan. People who brush their teeth
48:08
are more likely to engage in all kinds
48:10
of other healthy behaviors. This
48:12
turns out to be the central problem with
48:15
comparing the health of vegetarians to
48:18
the health of non-vegetarians.
48:19
If you just look at the raw
48:21
data, vegetarians and vegans have like
48:24
way lower rates of everything. everything,
48:26
diabetes, strokes, cancer,
48:29
they live longer. Basically
48:31
any health thing that you can name,
48:33
vegetarians do better and vegans
48:35
do even better. But that
48:37
doesn't necessarily mean that
48:40
it's the diet that is doing it. Because
48:43
only around 5% of the population
48:45
is vegetarian or vegan, and the non-vegetarians
48:48
is like everybody else. So you're basically
48:50
taking a very small subset
48:53
of the population who are like way
48:55
more health conscious
48:56
in a million ways.
48:59
Vegetarians get more physical activity than
49:02
non-vegetarians. Vegetarians
49:04
are less likely to smoke. They are less
49:06
likely to drink. They're more educated.
49:09
They tend to be from like more affluent
49:12
backgrounds. Although they actually have lower
49:14
incomes than the population at large,
49:17
but that's mostly of just the fact that they're
49:19
younger. And then one of
49:21
the things that this documentary does that I think
49:23
is a very interesting bait and switch
49:26
is throughout the documentary, they talk about like
49:28
the
49:28
benefits of a plant-based diet, but they always
49:31
add this little modifier. They say
49:33
a whole foods plant-based diet.
49:35
Yeah. Well, that's a big fucking difference. But
49:38
then they don't define what the fuck whole
49:40
foods means. And like in
49:42
these awful little montages they
49:45
have this b-roll of
49:47
like a family at McDonald's
49:49
and they're sitting there eating french fries and
49:51
it's like very clearly designed to be stigmatizing
49:54
but also french fries are
49:56
vegan French fries are like pretty
49:59
close to a whole food, right? You chop
50:01
up the potato and you cook it. What they're
50:03
basically doing is like very clearly
50:06
promoting a vegan diet. Like the
50:08
whole movie is like, you know, milk is
50:10
poison meat is poison, et cetera. But they're
50:13
also giving themselves this like little asterisk
50:16
of like, well, if you're a vegan and you still
50:18
get cancer, like the foods
50:20
you ate weren't whole enough.
50:23
Yeah. That's the difference between like
50:25
the kind of veganism that eats
50:28
at like vegan restaurants and
50:30
drinks a bunch of green juice and all that sort of stuff. And
50:32
then like your vegan roommate in college
50:35
who kept yelling about how Oreos are vegan.
50:38
Yeah. Where you're like, yeah, yeah, yeah, yeah, yeah.
50:40
There's
50:40
a way to
50:43
eat in a way that people sort of like associate
50:45
with a lack of health for
50:48
kind of any way of eating. Yeah, exactly.
50:50
So like, if you look at surveys of
50:52
like the food behavior
50:55
of vegans and vegetarians, it's like they eat
50:57
less fat, They eat less sugar, they
50:59
eat more fiber, they eat fewer
51:01
calories overall, they eat
51:03
foods with higher nutrient density. I'm
51:06
not married to the idea that
51:09
any of these other things are necessarily explaining
51:11
the differences. I don't think there's
51:13
a diet that is best for everybody, but
51:16
it's like there's
51:16
almost no one who
51:19
has the same patterns as
51:21
the average American but doesn't
51:23
eat animal products. The fact that vegetarians
51:26
and vegans live longer and have all these better health
51:28
markers, maybe that means that
51:30
vegetarian diets are healthier? We can't rule that
51:33
out, but we can't say it with any confidence
51:35
either because there's like 15 or 20
51:38
differences between vegetarians
51:40
and non-vegetarians. Sure. I mean, it would also
51:42
be interesting to look at people who
51:44
are vegetarian for religious reasons. I'm
51:47
thinking of Hindus, right? Yeah. Okay.
51:50
Does that play out differently or the same? Yeah, it's very
51:52
weird to me that the vast
51:53
majority of studies on this only
51:55
look at UK or US
51:58
vegetarians when like 40% of
52:01
the population of India is vegetarian.
52:03
Oh, interesting. Although it's also an interesting
52:06
demonstration of how difficult this is because
52:09
in rich countries, being
52:12
a vegetarian is a sign of high socioeconomic
52:14
status, right? It's like
52:16
Reese Witherspoon in like big little liars.
52:19
But in poor countries, vegetarianism
52:22
is associated with low socioeconomic status
52:24
because when When you're super poor, you're
52:26
eating basically just like rice or
52:29
potatoes or like some other like super
52:31
basic starch because you can't afford anything
52:34
with higher protein or higher fat. And
52:36
so as people move up the income
52:38
ladder in poor countries, what tends to happen is they
52:40
don't actually eat more calories, but they eat
52:42
more higher end food, things
52:45
like
52:45
meat and eggs and dairy. So
52:48
it also speaks to how this
52:50
is always couched as like a biological
52:52
thing and how this affects the body, but like it's
52:54
extremely social. Right.
52:57
The idea that we could just cleanly say
52:59
this is straightforwardly because
53:01
of vegetarianism or because
53:04
of a fully plant based diet feels
53:06
like, again, I'm not sure that we've eliminated
53:09
everything else just yet. Well, one thing I will
53:11
say, so I called up
53:13
Catherine Fleagle to help me with this episode,
53:15
because we've kind of become pals
53:18
since we did an episode on her like a year and a half
53:20
ago. I love everything about
53:22
this. I know I, she's like an actual
53:25
methodology queen. I'm like joking
53:27
about my methodology queen status, but she
53:29
like actually knows what she's talking about. So like I
53:31
check in with her when I have like a technical question.
53:33
We're like the fantasy football.
53:36
Yeah.
53:39
A lot of the studies
53:40
on vegetarians versus non-vegetarians
53:42
do use statistical controls. So
53:44
like we've controlled for income, we've controlled for age,
53:46
we've controlled for gender, etc. So
53:49
statistical controls allow you to compare
53:51
like for like. So vegetarians on average
53:54
are much younger than non-vegetarians. So if
53:56
you're going to do a study, you have to control
53:58
for age because otherwise it's gonna be like
54:00
there were no heart attacks because young people
54:02
don't really have heart attacks. So, controlling
54:04
for age allows you to compare like 60-year-old
54:06
vegans
54:07
and 60-year-old non-vegans, right?
54:10
And like rich vegans and rich
54:12
non-vegans. You can hold everything else constant
54:15
so you're comparing like for like, which is great.
54:18
However, you can only control
54:21
in that way for the variables
54:23
that you gather.
54:24
So, if you have data on socioeconomic
54:26
status, then you can control for it. If you have data
54:29
on gender, you can control for it. Yeah. Very
54:31
few of the studies that I found
54:32
controlled for health insurance status. That
54:34
seems like a big one, dude. I know. And
54:38
one of the weirdest findings, there's
54:40
all this research showing that vegans and vegetarians
54:43
have higher rates of depression
54:45
and anxiety. But I don't think
54:47
that's the fucking diets. I think they're more
54:49
likely to have health care. Sure. A
54:52
condition of existence at this point is a certain
54:54
percentage of people are just going to be depressed and anxious
54:56
and like the differences who can access
54:59
treatment and who can't. Right. So
55:01
like I don't think that that means anything,
55:02
but then I also don't think that the health stuff
55:05
really means anything either because you
55:07
can't control for all
55:09
of the behaviors
55:10
that distinguish vegetarians from
55:13
non-vegetarians. This is where the vitamin
55:15
E comparison comes in. A lot of those
55:17
studies on people who eat vitamin E
55:19
live longer. They did control for things like socioeconomic
55:22
status
55:22
and gender and age and all this other stuff that you're
55:25
supposed to control for, but there's some residual
55:28
stuff that you can't control for because you
55:30
don't have every single piece of
55:32
data that you would need. To control
55:34
for it. Yeah, yeah, yeah. Yeah. I
55:37
read a really interesting article about
55:38
the problem with observational
55:42
studies. It used to be that
55:44
the threshold for publishing
55:46
these kinds of studies was you
55:49
would need a three to four
55:50
times greater risk to
55:53
publish something. People who eat apples are four
55:55
times more likely to have heart attacks or
55:57
whatever. A lot of the study's coming out.
56:00
about these kinds of risks and a lot of the studies
56:02
on vegetarians and vegans, it's like, oh, you're
56:05
at 10% higher risk of
56:07
a heart attack. Yeah, which your overall
56:09
risk for a heart attack was like 1% and
56:11
now it's 1.1%. Yeah, it's very
56:14
small. And then these small
56:17
gradations are easily
56:18
swamped by like, oh, all the
56:21
shit you couldn't control for. Another one of the
56:23
articles that I looked at pointed out that smokers
56:26
are 20 times more likely
56:28
get lung cancer than non-smokers. You
56:32
can say, okay, smokers also have some
56:34
characteristics that make them different. It's
56:36
a minority of the population. There's other things
56:38
that distinguish them. If we're talking
56:40
about a 20 times difference, it's
56:43
like, oh, well, people who smoke don't get as much
56:45
sleep. It's like, all right, maybe that knocks
56:47
it down to 19 times more likely. Yeah,
56:49
but it's a pretty decisive impact. So
56:52
much of this whole field of
56:54
observational studies, its tiny
56:57
effects, and given everything else
56:59
we know
57:00
about the muddiness of this data and the bad
57:03
track record of these fucking studies, we
57:05
just can't really say anything.
57:08
Well, there's also a bunch of stuff that there
57:10
have been illustrated links between
57:13
these things and heart disease, things
57:15
like experiencing racism
57:19
or experiencing weight Right? Like
57:22
all of these things are linked
57:24
to some kind of heart health conditions,
57:27
right? You're not going to be able to control
57:29
for that stuff necessarily either,
57:32
right? Like, there's just like a bunch
57:34
of stuff that like structurally is going
57:36
to be too difficult to
57:39
build into any one study.
57:41
Right? I mean, I also want to say that like, it
57:43
also is plausible to me that
57:46
like, I don't know, vegetarian vegan diets are better for
57:48
you. Like none of this rules out vegetarian
57:51
or vegan diets and like people,
57:53
Aubrey, people People who go out of their way
57:55
to like dunk on vegetarians online
57:58
are like some of the the baddest fucking
58:00
people I've ever come across. Just
58:02
mind-numbingly boring. So
58:05
boring. I came
58:07
across this first when I was researching our carnivore
58:10
diet episode, where there's these
58:12
weird fucking meat influencers
58:15
who make up these vegans to dunk
58:17
on. They're like, vegans don't want to admit
58:19
me. And it's like, dude, just
58:22
eat meat or don't eat meat, man. But shut the fuck
58:24
up about what other people are doing. It's
58:26
so fucking
58:27
weird. Jesus Christ. There's
58:29
a real strain of this in
58:31
like anti fat activist stuff
58:33
where they'll just like make up shit that
58:35
they're like fat activists say
58:38
it's fat phobic to have a decent
58:40
resting heart rate and you're like, yeah,
58:42
one has ever said that. Do what you want to do,
58:44
man. There's I watched this presentation
58:46
by this academic lady who did like the myth
58:48
of vegetarianism or something and she was like,
58:50
you say you care about animal rights, but what
58:52
about the animals that are killed to grow crops?
58:55
What? I
58:58
don't think that vegans are pretending
59:00
that their actions have no effect on
59:02
any animals whatsoever.
59:04
I think it's just really easy
59:06
to opt out of the worst forms
59:08
of animal torture. And people
59:11
are doing that. And it's such a fucking
59:13
weird thing to do with your time, to criticize
59:16
other people who are trying to
59:19
have less of an impact on living
59:21
creatures and the planet.
59:22
It's like, you're just as bad as me. We're
59:25
all kind of bad, so it just seems like a weird
59:27
thing to be proud of. It's just three
59:30
cattle ranchers in a trench coat. Five
59:33
million Joe Rogan listeners in a trench coat, but yes.
59:35
Jesus Christ. So I want to end with a
59:37
quote from the Annals
59:39
of Internal
59:40
Medicine. This is one of the only
59:42
editorials I found that
59:44
says what I have been thinking for many years
59:47
now. Ooh. It's an issue where
59:49
they go over a lot of these meta-analyses
59:52
of red meat. This is during the fucking red meat wars
59:54
in 2019 when a bunch of studies come out about this.
59:57
This editorial says It
1:00:00
may be time to stop producing
1:00:02
observational research in this area. These
1:00:04
meta-analyses include millions of participants.
1:00:07
Further research involving much smaller cohorts has
1:00:10
limited value. High quality, randomized
1:00:12
controlled trials are welcome, but only
1:00:14
if they're designed to tell us things
1:00:15
we don't already know. I love
1:00:18
to see this, that people
1:00:20
in the field are like, let's not do
1:00:22
this anymore. Every single time one of these
1:00:24
fucking studies comes out, it's like red meat will
1:00:26
kill red meat will save you, whatever it is, coffee,
1:00:29
breakfast, anything. We
1:00:31
know how these things are going to be framed
1:00:33
in the media, and we know how they will
1:00:36
be received by readers. The
1:00:38
only reason you click on
1:00:40
a headline about like, drinking
1:00:42
coffee in the morning causes cancer, drinking coffee
1:00:45
in the morning cures cancer. The only
1:00:47
reason to read those stories is to adjust your
1:00:49
own habits. The general population
1:00:51
is not interested in these studies
1:00:53
for like biological, epidemiological,
1:00:56
population level reasons. Nor are we reading
1:00:58
the original text of the studies. Which
1:01:01
always say we cannot determine
1:01:02
cause, yes. Right, all it's doing
1:01:04
is like fanning the flames of like
1:01:06
the closest sort of diet
1:01:09
world gets to culture wars. Yeah.
1:01:12
But this is a road to nowhere, or it's a road to where
1:01:14
we already are is maybe a better
1:01:16
way to put that. The whole thing is this quest
1:01:18
for like the best diet. I think
1:01:21
that is a pointless quest. Are
1:01:23
vegetarian diets better for you? It
1:01:25
seems like a very simple question,
1:01:27
but it turns out the science that
1:01:29
we have available to us can't really answer it.
1:01:32
And that's basically going to apply for any kind
1:01:35
of dietary pattern. If you are just happier
1:01:37
on a vegetarian diet than not on one,
1:01:40
then that works great for you and you should do it. For
1:01:42
other people it's going to be Mediterranean, for other people it's going to
1:01:44
be low fat, for other people it's going to be nothing. I
1:01:46
don't know
1:01:46
that more of these studies is really doing very
1:01:49
much for us. Okay, so what I'm hearing
1:01:51
is that I should go vegan
1:01:54
and paleo at the same time? Just
1:01:56
hearing you say that made me raise my flag.
1:01:58
Hahaha no much! Oh
1:02:00
no, I'm going to HR. That just happened.
1:02:03
have them...
