How does fiber improve your digestive health?

Fiber improves digestive health in several key ways. Soluble fiber dissolves in water to form a gel-like substance that slows digestion, helping regulate blood sugar and cholesterol while feeding beneficial gut bacteria. Insoluble fiber adds bulk to stool and speeds up the movement of food through the intestines, preventing constipation and reducing the risk of conditions like diverticulitis and colorectal cancer. Fiber also acts as a prebiotic, nourishing the good bacteria in your gut microbiome. These bacteria ferment fiber and produce short-chain fatty acids, which strengthen the intestinal lining and reduce inflammation. A healthy gut microbiome supported by adequate fiber intake is linked to better immunity, mood, and overall digestive function.
