The power of food to impact your health is not a new idea, but it is only with emerging research on the human gut microbiota that scientists are beginning to understand exactly how this happens. Whether you eat a strawberry or a hamburger, the food components enter your digestive system and encounter the intestinal microbes. Through a series of complex events, the microbes living in your gut influence how your body processes the food. And in turn, the food can change the microbial community living inside you. The products of these diet-microbiota interactions can profoundly change your health. ‘You are what you eat’ has never been so true!
