A high-fiber diet benefits digestive health by promoting regular bowel movements and reducing the risk of gastrointestinal disorders. Fiber regulates digestion by maintaining gut motility and supporting the growth of beneficial gut bacteria. Foods rich in fiber, such as fruits, vegetables, and whole grains, can help prevent constipation and maintain overall gut health. Additionally, a high-fiber diet can contribute to weight management by enhancing feelings of fullness, ultimately leading to better overall nutrition and health outcomes.
