Fiber plays an important role in cardiovascular health by aiding in the regulation of cholesterol levels and promoting healthy digestion. Soluble fiber, found in foods like oats and beans, can help lower LDL cholesterol, thereby reducing the risk of heart disease. Additionally, high-fiber diets support healthy blood pressure and weight management, both critical factors in maintaining a healthy heart. Furthermore, adequate fiber intake supports gut health, as it nourishes beneficial gut bacteria, contributing to overall metabolic health and enhancing the performance of bodily functions.
