So, there was this guy named Hippocrates who said “All disease begins in the gut” about 2,500 years ago, and you know what? He was right. Your gut is responsible for absorbing the nutrients from your food, which in turn help you make the hormones you need and break down and eliminate the ones you don’t. It houses a whole lot of organisms—we’re talking more organisms than there are cells in the body—that influence your mood, your weight, inflammation, and your overall hormonal health.
