Dr. Will Bulsiewicz (or "Dr. B") is an award winning gastroenterologist, internationally recognized gut health expert and the New York Times-bestselling author of Fiber Fueled and The Fiber Fueled Cookbook. He sits on the Scientific Advisory Board of ZOE, has authored more than twenty articles published in peer-reviewed scientific journals, has given more than forty presentations at national meetings, presented to Congress and the USDA, and has taught over 10,000 students how to heal and optimize their gut health. This is our third conversation with Dr. Bulsiewicz. Today Dr. B explains in detail the difference between food allergy and food intolerance, concepts that are important to differentiate. Unlike food allergy, food intolerance is usually isolated to digestive issues, and in general does not involve the immune system response. Furthermore, it is possible to "train up your microbiome" to work through food intolerances following a framework Dr. B calls "GROWTH". Tune in to learn more about the fascinating science and research in this field, and simple actionable solutions to improve your gut health through food!
