The impact of fiber on gut health is profound, as it supports d digestion and promotes a healthy digestive tract. Fiber adds bulk to the stool, facilitating regular bowel movements and preventing constipation. It also acts as a prebiotic, nourishing beneficial gut bacteria, which can help improve nutrient absorption and enhance immune function. High-fiber foods can also regulate blood sugar levels and lower cholesterol, contributing to overall gut and cardiovascular health. Thus, a fiber-rich diet is essential for maintaining optimal gut functionality.
