e’ve all heard the phrase, “You are what you eat,” but the connection is more than just physical because food impacts our mood, too. During the last decade, there have been an increasing number of studies exploring what’s called the gut-brain axis and the role that microorganisms in the gut play in mental health conditions like anxiety, stress, depression and other disorders. Depression is a leading cause of disability in the U.S. and worldwide. There are long-held views in medicine that depression is caused by imbalances in brain levels of serotonin—the neurotransmitter that plays a key role in regulating mood and other functions like digestion and sleep. These beliefs resulted in decades of extensive use of antidepressants, most of which boost serotonin in the brain. However, research by University College London, published in July in the journal Molecular Psychology, found “no consistent evidence of there being an association between serotonin and depression, and no support for the hypothesis that depression is caused by lowered serotonin activity or concentrations.” Michael Gershon, M.D., a Columbia University professor of pathology and cell biology, and author of The Second Brain, has explained to psychologists that “scientists were shocked to learn” that about 90 percent of serotonin is not created in the brain, but is actually produced in the gut and carried from there to the brain, not the other way around. This relationship is called the gutbrain axis. A recent literature review of 26 studies suggests that imbalances in gut bacteria can disrupt the two-way communication along the gut-brain axis, leading to depression and other psychiatric issues.
