What it is
Fructooligosaccharides (FOS) are a type of carbohydrate that acts as a prebiotic fiber. They are naturally found in foods like onions, garlic, bananas, and chicory root. FOS can also be produced commercially from sucrose using enzymes.
Why it's used
Manufacturers add FOS to foods as a dietary fiber and a low-calorie sweetener. It can also enhance the natural flavors of foods. FOS is often found in dairy products, baked goods, beverages, and confectionery.
Health notes
FOS is generally recognized as safe (GRAS) by the FDA for use in foods. As a prebiotic fiber, it can support the growth of beneficial gut bacteria. JECFA has evaluated FOS and established an acceptable daily intake. Some studies suggest potential benefits for gut health and mineral absorption, but more research is needed to confirm these effects.
Allergen info
FOS is not derived from any of the nine FDA major allergens. It does not contain gluten.
