Why do some people like broccoli and others find it disgusting? What makes some people vote liberal and some vote conservative? “Trust your gut” is an oft used and usually sound piece of advice, but did you know it actually has a scientific basis? Dr. Bill Sullivan joins us today with evidence that our microbiota – the trillions of microbes living in our gut – influence and affect our behavior and moods.
Dr. Sullivan, author of National Geographic’s Pleased To Meet Me: Genes, Germs, and the Curious Forces That Make Us Who We Are, holds a doctorate in cell and molecular biology and is an award-winning professor at the Indiana University School of Medicine in Indianapolis, where he studies genetics and infectious diseases.
