Fiber 101: Soluble, Insoluble, Functional Fiber, and Resistant Starch

from Real World Nutrition · host Shelley A. Rael, MS RDN LD

Fiber is often oversimplified as something that “keeps you regular.” In reality, it plays a far more complex role in digestive health, blood glucose regulation, cholesterol management, gut microbiome diversity, and long term disease risk. In this episode, the discussion continues the carbohydrate series by breaking down the different types of fiber, including soluble fiber, insoluble fiber, functional fiber, and resistant starch. The episode also connects fiber recommendations to the Dietary Guidelines and explains why the source of carbohydrate matters. Listen: Episode 228 What Are Carbohydrates?
