Fiber plays a crucial role in digestion and gut health. It aids in regulating bowel movements by adding bulk to the stool, which helps prevent constipation. Additionally, dietary fiber supports the growth of beneficial gut bacteria, contributing to a balanced microbiome and enhancing overall digestive health. Soluble fiber can help lower cholesterol levels and regulate blood sugar, reducing the risk of diabetes. A high-fiber diet also promotes feelings of fullness, which can aid in weight management. Overall, fiber is essential for maintaining a healthy digestive system.
