What is Polydextrose?
Polydextrose is comprised of sugars linked in chains and is a synthetic ingredient often used in food and medicine. Polydextrose is taken by mouth as a prebiotic, and it is also found in certain treatments for itchy skin, eczema, impaired glucose intolerance, and for infant development. It's also used as a sweetener and to improve the texture of certain foods. Other research shows that polydextrose may help to relieve the itchy, scaliness of eczema in some patients.
Because polydextrose may have a prebiotic effect, it is often added to supplements that enhance prebiotic activity. It may also help to support weight management by helping people to feel fuller for longer periods of time. It is a source of dietary fiber that is often added to a variety of foods claiming to be sugar-free, no-sugar-added, or in those that have reduced sugar. Some common food items that might contain polydextrose include cereals, snacks, beverages, dairy items, sauces, and baked goods. It may also be found in certain sauces, baked items, and dairy products that are traditional as well.
