In todays episode I speak with Dr. Jason Hawrelak on the latest research in to our gut microbiome. We discuss the importance of a diverse microbiome, the role of strain specificity when recommending probiotics, the specific use of prebiotics and how many of us have been using this term far too loosely. We also discuss fecal banking (!), and the impact of medications such as proton pump inhibitors and antibiotics, and the impact of diet on ecosystem diversity and gut health.
