Dietary Soluble Fiber

Dietary soluble fiber is a type of carbohydrate that dissolves in water to form a gel-like substance. It is found naturally in foods like oats, beans, apples, and citrus fruits. In food processing, it can be extracted from sources such as corn, chicory root, or psyllium.

Manufacturers add soluble fiber to foods to improve texture, add bulk, and enhance mouthfeel. It is often used in baked goods, cereals, and beverages to increase fiber content. It can also act as a fat replacer and help with emulsification in some products.

Dietary soluble fiber is generally recognized as safe (GRAS) by the FDA for use in food. Consuming adequate amounts of soluble fiber is associated with benefits like improved digestive health and can help manage blood sugar and cholesterol levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated dietary fibers. While generally considered beneficial, very high intakes can sometimes cause digestive discomfort.
