Royal Institution Christmas lectures 2005: the truth about food
Have you ever considered that when you eat food it becomes you? In just a year molecules from food replace almost every molecule in the body.

Throughout the world people eat strikingly different foods and many would recoil at what their global neighbours would consider a treat. But our need for food also unifies all people on the planet.

This year former Chair of the Food Standards Agency, Sir John Krebs helps us to uncover 'The truth about food'.
