Gut Bacteria

Have you ever felt butterflies in your stomach or that feeling in your gut that you shouldn't do something? When we are nervous or overwhelmed, we are likely to get signals from our "second brain." No, it's not some scientific breakthrough that scientists have found a second brain in the human body that has never been discovered. Rather, hidden in the walls of our digestive system, this second brain or the brain in your gut, is changing medicine's understanding of how digestion, depression, mood swings, and even how we think are related to each other.
