What it is

Prebiotic dietary fiber is a type of fiber that feeds beneficial bacteria in the gut. It is often derived from plant sources like chicory root, onions, garlic, and bananas. Prebiotic fibers are typically produced through processes like extraction and purification from these natural sources.

Why it's used

Manufacturers add prebiotic dietary fiber to foods to promote gut health and improve texture. It can act as a bulking agent and a source of soluble fiber. It is commonly found in snack bars, cereals, dairy products, and baked goods.

Health notes

Prebiotic dietary fiber is generally recognized as safe (GRAS) by the FDA for use in foods. It is known to support a healthy gut microbiome, which may have broader health benefits. International bodies like JECFA and EFSA have evaluated dietary fibers. While generally considered beneficial, some individuals may experience digestive discomfort like gas or bloating when consuming large amounts of prebiotic fiber.

Allergen info

Prebiotic dietary fiber is not typically derived from major allergens. Gluten content depends on the specific source; for example, if derived from wheat, it may contain gluten. Otherwise, it is not a major allergen.
