The Power of Fiber on a Vegan Diet
Fiber, an indigestible carbohydrate found in plant foods, offers numerous health benefits that are especially prominent in a whole-foods, plant-based diet. A high-fiber diet aids in weight management by promoting a feeling of fullness, which can reduce overall caloric intake. It also plays a critical role in regulating blood sugar levels, as soluble fiber slows the absorption of sugar into the bloodstream. Furthermore, fiber helps lower LDL ('bad') cholesterol, reducing the risk of heart disease. For digestive health, fiber adds bulk to stool, ensuring regularity and preventing constipation. This bulking effect also helps cleanse the digestive tract and may reduce the risk of certain colon diseases. Vegans can effortlessly consume a balanced mix of soluble and insoluble fiber by incorporating a diverse range of plant foods into their meals.
