Fiber plays a crucial role in reducing the risk of chronic diseases by promoting healthy digestion and regulating blood sugar levels. It aids in maintaining a healthy weight, as high-fiber foods often require more chewing and take longer to eat, promoting satiation. Additionally, fiber can lower cholesterol levels, reducing the risk of heart disease. A diet rich in fiber is associated with lower incidences of colon cancer and other gastrointestinal disorders. Including fruits, vegetables, whole grains, and legumes can contribute to overall well-being.
