Fiber
Indigestible plant material that supports digestive health and gut microbiome diversity.
Dietary fiber encompasses non-digestible carbohydrates and lignin from plant sources. Soluble fiber (beta-glucan, psyllium, pectin) forms a gel in the gut, slowing glucose absorption and binding bile acids to lower cholesterol. Insoluble fiber (cellulose, wheat bran) promotes regular bowel movements. Prebiotic fibers (inulin, FOS, GOS) selectively feed beneficial gut bacteria, supporting microbiome diversity. Adequate fiber intake (25-38 g/day) is associated with reduced risk of cardiovascular disease, type 2 diabetes, and colorectal cancer.
