Deep dives

Fiber and Carbohydrates

The podcast episode delves into the myth that fiber is an essential nutrient and the importance of carbohydrates in our diets. The speaker suggests that the fiber narrative has been pushed to justify the consumption of carbohydrates. It is highlighted that fiber is an indigestible polysaccharide that the body doesn't require. The speaker further explains that throughout history, humans have survived without consuming fiber, including during the ice ages. Additionally, the podcast discusses constipation and points out that, contrary to common belief, increasing fiber intake does not alleviate constipation. Instead, the focus should be on a well-rounded diet, including essential nutrients like fats and proteins, rather than relying on fiber.
