What do the bacteria living in your gut have to do with your immune system?

Your intestines are home to many different kinds of bacteria (and some non-bacterial organisms as well). Together they’re called the “gut microbiome.” They come from the food you eat – and whatever else gets into your mouth. Bacteria start colonizing your gut at birth.

Your gut microbiome aids in digestion and produces vitamins and other compounds that affect your health. It seems to play a role in many other health-related functions, including metabolism, cardiac health, and mood.
