Fiber plays a vital role in digestion by promoting regular bowel movements and preventing constipation. Soluble fiber helps regulate blood sugar levels, while insoluble fiber aids in adding bulk to the digestive system, facilitating the passage of food through the intestines. Consuming an adequate amount of dietary fiber can support gut health, reduce the risk of digestive disorders, and contribute to overall well-being. Including high-fiber foods like whole grains, fruits, and vegetables is essential for optimal digestive health.
