Is Depression Linked to the Gut Biome?

Known as the “second brain,” the gut possesses its own nervous system and hosts between 50–100 million microbes. New research indicates that the trillions of microbes inhabiting our gut continually exchange information with the brain and influence our state of being, emotions and pain.

The important implication here is that mental health issues may not always be the result of a dysfunctional brain. The food we eat and the way it interacts with the gut’s microbiota could be responsible for conditions such as depression.
