Fiber plays a vital role in maintaining digestive health by promoting regular bowel movements and preventing constipation. It adds bulk to the stool, making it easier to pass. Additionally, fiber aids in controlling blood sugar levels and reducing cholesterol, contributing to overall heart health. Soluble fiber, in particular, helps slow digestion, promoting a feeling of fullness and aiding weight management. A diet rich in fiber also supports a healthy gut microbiome, which is essential for nutrient absorption and overall well-being.
