Most Replayed Moment: Are You Really Gluten Intolerant? It Could Be This Instead!

Dr. Will Bulsiewicz, a leading gastroenterologist and microbiome expert, explains why bloating, gas, and constipation are often misattributed to gluten when the real culprit is microbiome dysbiosis. The episode reveals how gut bacteria composition drives digestive symptoms and inflammation, and why eliminating gluten without addressing underlying microbial imbalance leaves the root problem unsolved.
