How Tiny Microbes In Your Gut Affect Your Mood


Dr. Emeran Mayer, author, "The Mind-Gut Connection"

For many of us during the holidays, we let our stomachs control our brains, and we end up eating just about anything our hungry gut wants.

Now, with the start of 2017, we try to put our brains back in control and eat in healthy moderation whether our stomachs like it or not.

But this dichotomy between brain and stomach may be just an illusion, as science learns how deeply connected the two are.

Researchers are finding that the brain and the gut communicate, and physical and mental health issues even can crop up if that communication is disrupted.

Dr. Mayer presented his new book on the topic, "The Mind-Gut Connection: How the Hidden Conversation Within Our Bodies Impacts Our Mood, Our Choices and Our Overall Health" at Warwicks in La Jolla, Monday.

Dr. Mayer discusses the relationship between gut microbes, depression and other diseases, Tuesday on KPBS Midday Edition.
