What it is
Prebiotic corn fiber is a type of soluble dietary fiber derived from corn. It is produced by processing corn starch to create a fiber that resists digestion in the small intestine and ferments in the large intestine.
Why it's used
Manufacturers add prebiotic corn fiber to foods to increase their fiber content and act as a prebiotic, which feeds beneficial gut bacteria. It is often found in snack bars, baked goods, and beverages.
Health notes
In the US, prebiotic corn fiber is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. It is fermented by gut bacteria, which can produce gas and may cause digestive discomfort in some individuals, especially at high intakes. International bodies like JECFA have evaluated similar fibers, but specific evaluations for prebiotic corn fiber may vary.
Allergen info
Prebiotic corn fiber is not derived from any of the nine major allergens. It does not contain gluten.
