Dr Chris van Tulleken is on a mission to find out what we’re eating, why, and who or what might be influencing our decisions. And he’s starting his quest to uncover food truths with the most eaten meat in the world, and one of the most numerous animals on our planet: chicken.

He’s recently been forced to confront a serious gap in his food knowledge - what happens before it gets to our plates - and has decided this, the world’s most popular meat, is an ideal starting point.

Chris’ initial investigations reveal the vast scale of modern chicken consumption; and how a once revered jungle fowl was manipulated to become a modern food success story, a fast-growing heavy-breasted beast to feed the masses.

Now, he's torn: is this a triumph of human ingenuity – or the creation of a monster?
