Fiber is an essential component of a healthy diet, primarily found in fruits, vegetables, whole grains, and legumes. It aids digestion by promoting regular bowel movements and preventing constipation. There are two types: soluble fiber, which can lower cholesterol and stabilize blood sugar, and insoluble fiber, which supports gut health. A high-fiber diet is linked to a reduced risk of chronic diseases, including heart disease and diabetes. Recommendations suggest consuming 25-30 grams of fiber daily, making it important to include diverse fiber-rich foods for optimal health benefits.
