In the opening episode, they explore how this chemistry fuels and builds our bodies. Michael begins by trying the first meal most of us enjoyed, human breast milk, which contains everything a baby needs - fats, carbs, vitamins and minerals.

In San Francisco, they unravel why sourdough bread is so good for us, in the Philippines, they learn how a river weed - rice - has become a comforting staple food, and in Bulgaria, they discover why letting your mushrooms sunbathe may help you get a calcium boost from your dairy food.
