It's time for the gut microbiome to become a more central part of our conversation about health. That's why today I’m talking with Dr. Joseph Petrosino about the trillions of bacteria, viruses, and other microbes living in the gut, and why they reach far beyond digestion: into immunity, metabolism, sleep, and even mental health. We talk about how modern diets and antibiotics have reshaped that inner “garden,” when testing is actually useful, and how close we are to more precise ways of keeping people well instead of waiting until they’re sick.We get into what actually helps it, what modern life does to it, and where the science is headed next.Dr. Joseph Petrosino is chair of Molecular Virology and Microbiology at Baylor College of Medicine, director of the Alkek Center for Metagenomics and Microbiome Research (CMMR), and Baylor’s chief scientific innovation officer.Dr. Petrosino was a principal investigator for the NIH Common Fund Human Microbiome Project, and he established the CMMR in 2011 to develop and implement advanced technologies to understand how the microbiome impacts health and disease and translate this knowledge into new therapeutics and diagnostics.
