Why do so many of us find ourselves craving chocolate? What makes certain foods delicious to some people and revolting to others? Why do we cause ourselves pain by eating things like chillies?

These questions and more are answered in the conclusion to this fascinating three-part series, which focuses on our brains' relationship to food.

Along the way, our intrepid presenters Michael Mosley and James Wong bravely enter a chilli-eating contest at a Bristol festival, and in Peru James follows the fiddly process of turning cocoa beans into chocolate while Michael gets tipsy on yucca-based booze.

All in the name of science.
