Understanding the Impact of Food Groups on Health

What’s your favourite food? A hamburger, a slice of cake, a pizza? Eating is something we all do every day but most of us rarely think about what actually happens in our bodies after we put food into our mouths.

In this episode, we catch up with Dr Chris Van Tulleken to speak about his forthcoming Royal Institution Christmas Lecture series telling us everything we need to know about what’s happening in our bodies when we eat.

He tells us what actually happens when we put food into our mouths, what’s going on in our bodies once food is in there, and why farting is just part of the process.

BBC Four and iPlayer, 9pm, on 29, 30 and 31 December.
