Fiber, Soluble

carbohydrate Unit: g

Soluble fiber dissolves in water to form a viscous gel in the gut, slowing the digestion and absorption of carbohydrates and binding bile acids to lower LDL cholesterol. Oats, barley, apples, legumes, and psyllium are especially rich sources. This mechanism is a key reason high-fiber diets are associated with reduced cardiovascular disease risk.
