Fibermaxxing FTW: Meet the Neglected Nutrient That's the Key to Health

Move over protein, it's time to fibermaxx! Fiber has always been the neglected stepchild of nutrients: it's never been seen as essential, and some of its earliest enthusiasts were poop-obsessed oddballs. Take the inventor of cornflakes, John Harvey Kellogg. Inspired by the gorillas he saw at the zoo, he was fiber's first popular champion—but he also went around making people sniff his own perfect poops, and he believed that eating a plant-based, fiber-heavy, and condiment-free diet would help achieve his goal of reducing masturbation. It wasn't until surprisingly recently that scientists realized that fiber doesn't just prevent constipation—eating enough of it cuts your overall risk of death by about a quarter by lowering your cholesterol, helping keep your blood sugar and your weight stable, and preventing cancer. So it's a huge problem that nearly 95 percent of Americans aren’t getting enough of the stuff: on average, we eat about half what we should to hit government recommendations. This episode, we've got the story of fiber's embarrassing origins, the scoop on what all the different kinds of fiber actually are and do, and the emerging science behind its most magical powers—plus, the top tips you need to get more of it, deliciously and without digestive discomfort. Listen in—and, if you don't end up fiber-obsessed, too, we'll eat our whole-grain hats!
