In this episode, Wendy speaks with gastroenterologist, author, and microbiome researcher Emeran Mayer. Emeran is a world renowned expert in the connections between the gut and the mind, and brings a biological lens to the concept of interconnection. This conversation covers many topics, including: his interest in mind-body connection; microbiome overview & current questions; how we've inherited systems of communication from microbes; gut-brain connections, and the concept of the "second brain"; how meditation might affect our microbes; gut-immune connections; the importance of barriers, and what goes wrong in "leaky gut"; barrier compromise as common core of nearly all chronic disorders; stress and diet as key factors affecting our gut permeability; what we can do to protect our gut; equity issues around healthy food access; the gut as a sense organ; reductions in the diversity of microbes on the planet; the role of antibiotics and environmental destruction; development of the microbiome in pregnancy and infancy; implications for our concept of self; balance between reductionism and embracing complexity in science; and the need for more of the feminine archetype in our world.
