Millions of nerve cells and micro-organisms (bacteria, archaea, and aukarya) line the gut and interact with each other to influence our mods and provide other benefits. The microorganisms of our micorbiota are unique to each individual and helps strengthen the muscle cells of our intestinal wall, aid in digestion, and support our immune system. 

Over 90% of serotonin is produced in our gut, an interaction between the macrobiota and nerve cells. Because serotonin influences so many regulatory functions and helps regulate our moods, maintaining a happy, healthier gut is part of eating for mood regulation.
