About this episode

Chris Kresser explores the science of dietary fiber and its impact on gut health, emphasizing whole foods over supplements.

In this episode of Revolution Health Radio, Chris takes a deep dive into the science of dietary fiber, fiber supplements, and microbiome health. He explains why the benefits seen in high-fiber diets may come from whole foods rather than isolated fiber supplements, and why aggressively increasing fiber intake can worsen bloating, gas, and gut dysfunction for some people. He explores the latest research on fiber, short-chain fatty acids like butyrate, gut permeability, and microbiome balance while unpacking the limitations of observational nutrition studies. He also shares practical strategies for improving fiber tolerance, supporting digestive health naturally, and choosing safer approaches for sensitive guts.
