She suggests ideas for how to live a less diet-obsessed life, intuitively.

Your brain hallucinates your conscious reality

Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality."

We are What We Eat

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.
