The tight connection between the brain and the gut
"The connection between the stomach and the brain is strong, and it starts in the womb. The gut and brain originate from the same cells in the embryo. One of the main ways the brain and gut remain connected is through the vagus nerve, a two-way chemical messaging system that explains why stress can trigger feelings of anxiety in your mind and butterflies in your stomach. Only 5 percent of your body’s serotonin is made in the brain; the rest is made, stored and active in the gut!"
