“In the Mind-Gut Connection, Dr. Emeran Mayer, executive director of the Oppenheimer Center for Neurobiology of Stress and Resilience at UCLA, offers the cutting edge into this developing science, showing the full impact and complexity of how the brain, gut, and microbiome that lives inside the digestive tract communicate with one another. As he explains, the connection between the mind and the gut is bidirectional: the gut talks to the brain and the brain talks to the gut. When this communication is out of whack, major health problems can crop up in both the mind and the body, including food sensitivities and allergies, digestive disorders, obesity, depression, anxiety, and fatigue.”
