Dietary fiber plays a critical role in promoting gut health. It adds bulk to the digestive system, aiding in regular bowel movements and preventing issues like constipation. Soluble fiber can help regulate blood sugar levels and lower cholesterol, while insoluble fiber supports overall digestive function. Fiber also acts as a prebiotic, facilitating the growth of beneficial gut bacteria. A high-fiber diet is linked to a reduced risk of gastrointestinal disorders and improved overall gut microbiome health.
