1/6. Five hundred volunteers and a team of celebrities cook up 40 intriguing experiments to explore how what we eat can changes our lives.

Fiona Bruce joins nine fast-food junkies placed under a strict regime at Paignton Zoo - following a gorilla's diet of raw fruit and vegetables. She also meets two truckers who swallow an unusual pill to get them moving, and learns all about good and bad bacteria from some cowboys.

Health: The Truth about Food 9.00pm BBC2
This gimmicky new series is notable for the contributions of its presenter, newsreader Fiona Bruce, who reveals herself to be a gigglesome thing with a jaunty sense of humour. And doubtless many of Fiona's male fans will just love hearing her talk rather coquettishly about erections.
The Truth about Food is yet another of those vaguely finger-wagging shows that purports to tell us what we should and should not be eating. It's almost terrifyingly light-hearted, and full of weird experiments. For instance, volunteers live in a zoo and eat like apes for a week to see if their cholesterol levels are reduced. And two game chaps talk about their sexual problems, with gratuitous, but quite funny, illustration from the naughty Cerne Abbas man. (Alison Graham)
