Description
In this episode of The Spoon Podcast, registered dietitian and longtime CNN food journalist Carolyn O’Neil joins Mike to traverse the fiberverse and discuss the growing trend of fibermaxxing. Carolyn discusses the science behind different types of fiber, and why Gen Z’s favorite prebiotic sodas are suddenly everywhere. She also breaks down how fiber actually works in the body, why most people get only half the recommended amount, and how social media, CPG innovation, and even CGMs are reshaping consumer nutrition habits.
