In this episode, Robby Barbaro explores the connection between your gut microbiome, inflammation, and blood sugar control, and explains why the bacteria living inside your digestive system may play an important role in insulin sensitivity. You'll also learn why probiotic supplements, despite all the attention they receive, may not be the most reliable way to improve gut health, and why the more powerful strategy may already be sitting in your kitchen. In this episode, you'll learn: • How the gut microbiome may be connected to type 2 diabetes • Why people with type 2 diabetes often have lower levels of certain beneficial bacteria • How gut bacteria that produce butyrate may help support a healthier intestinal lining • How an imbalance in gut bacteria may contribute to inflammation and insulin resistance • Why chronic inflammation can interfere with insulin signaling • What the research shows about probiotics and blood sugar control • Why probiotic supplements sometimes produce only modest or inconsistent results • Why many probiotic bacteria may not survive the acidic environment of the stomach • How fiber feeds the beneficial bacteria already living in your gut • Why beans, lentils, whole grains, vegetables, and fruit can support a healthier microbiome • How gut bacteria convert fiber into short-chain fatty acids like butyrate and acetate • Why these compounds may help support insulin sensitivity and glucose metabolism • How even simple dietary changes can begin shifting the gut microbiome • Why resistant starch from beans, lentils, and cooked-and-cooled potatoes, rice, and pasta can help feed beneficial bacteria The key takeaway isn't that you need to find the perfect probiotic supplement. It's that you can create a healthier environment for the beneficial bacteria you already have. Fiber-rich whole plant foods provide the fuel those bacteria need to produce compounds that support gut health, reduce inflammation, and help your body respond to insulin more effectively. Rather than trying to manage your microbiome from the outside in, this episode shows you how to support it from the inside out with the foods you eat every day. 👉 Learn more about the Mastering Diabetes Fall Retreat: https://www.masteringdiabetes.org/retreat-fall-2026/ The next retreat takes place October 29 through November 2, 2026 in Miami, Florida.
