This week, we talk institutional food. In particular food in hospitals: what are the challenges with feeding people in this setting, how food is viewed by the medical community, how we can introduce healthier foods into this system and what the impact might be.

Lulu Cohen-Farnell and David Farnell, owners of a "healthy catering company for child care centres", regularly speak out about the ways we can better feed vulnerable groups- from children to patients- and how their childcare catering company can inform a change in the way serve food to those who can't serve themselves.
