Michael Mosley and James Wong reveal the delicious physics, chemistry and biology hidden inside our food. They travel the world in a culinary adventure to search for the origins of our favourite foods and using specialist photography and CGI, they take us on a journey inside the most sumptuous food, right down to the molecular level.

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. As we grow, we continue to seek the same chemistry in our diet but from a wide variety of scrumptious fare, as Michael and James discover. 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.
