Dietary fiber is a crucial part of a healthy diet, yet many people don't fully understand its benefits. What exactly is dietary fiber? It's the part of plant foods your body can't digest or absorb. Unlike fats, proteins, or carbohydrates, fiber passes relatively intact through your stomach, small intestine, and colon. This journey helps regulate your body's use of sugars, keeping hunger and blood sugar in check. There are two types: soluble, which dissolves in water, and insoluble, which doesn't. Both types are important for different reasons. Why should you care about fiber? It can help prevent heart disease, diabetes, weight gain, and some cancers, and also improve digestive health. Ready to learn more? Let's dive into 26 fascinating facts about dietary fiber that will change how you look at your plate.
