The medical field has only recently begun to acknowledge the connection between mood, foodand the digestive tract (the organs that food and liquids travel through when they are swallowed, digested, absorbed, and leave the body as feces). If your brain is deprived of good-quality nutrition, or if free radicals or damaging inflammatory cells that can damage brain tissue are circulating within the brain’s space, consequences are to be expected. Serotonin, a neurotransmitter that helps regulate sleep and appetite, mediate moods, and inhibit pain is primarily produced in your digestive tract. Your gastrointestinal tract is lined with a hundred million nerve cells which communicate with your brain. This connection allows your diet and the neurotransmitters created in your GI tract to guide your emotions.
