Prebiotic Fibers

Prebiotic fibers are types of dietary fiber that feed beneficial bacteria in the gut. They are typically non-digestible carbohydrates found naturally in foods like onions, garlic, and bananas, or they can be produced commercially from sources like corn or chicory root through enzymatic processes.

Manufacturers add prebiotic fibers to foods to promote gut health and improve texture. They are often found in products like granola bars, cereals, baked goods, and dairy alternatives, where they can also act as a bulking agent or a source of sweetness.

Prebiotic fibers are generally recognized as safe (GRAS) by the FDA for use in food. They are known to support a healthy gut microbiome, which may have broader health benefits. International bodies like JECFA and EFSA have evaluated various prebiotic fibers. While generally considered beneficial, some individuals may experience mild digestive discomfort like gas or bloating when first consuming them or if intake is very high.
