Barley and Oats: Naturally High in Beta-Glucan Fiber
Barley and oats are among the richest natural sources of beta-glucan, a unique soluble fiber that forms a gel-like texture in the digestive tract. This fiber helps slow the digestion of carbohydrates, supporting steady energy release and a lasting feeling of fullness, which is why these grains are popular choices in meal-replacement and fiber-focused supplement formulas.
