We've probably all heard of “antihistamines,” medications that can ease symptoms of hay fever and other allergies. But what is “histamine”? It’s a vital chemical that our bodies produce, and it plays a role in a number of functions that support our health. Histamine intolerance seems to be increasingly common, but it’s difficult to diagnose. Some people may not be aware that they have it or how to treat it.In today’s episode of ZOE Science & Nutrition, Jonathan speaks with Dr. Will Bulsiewicz, ZOE’s U.S. medical director, to learn more about this flourishing area of research — and the best ways to identify and treat histamine intolerance.Will is a board-certified gastroenterologist, and New York Times bestselling author of the microbiome book Fiber Fueled.If you want to uncover the right foods for your body, head to zoe.com/podcast, and get 10% off your personalized nutrition program.Also, find top tips for gut health from ZOE Science & Nutrition: Download our FREE gut guide.Follow ZOE on Instagram.Mentioned in today’s episode: Resistant potato starch supplementation reduces serum histamine levels in healthy adults with links to attenuated intestinal permeability published in Journal of Functional FoodsHistamine and histamine intolerance published in The American Journal of Clinical NutritionHistamine intolerance: The current state of the art published in BiomoleculesIs there a nutrition topic you’d like us to cover?
