Polydextrose is a soluble fiber and sweetener used in a variety of applications. It is often used as a sugar replacement, especially when the goal is to reduce the amount of calories in the food. Polydextrose can provide bulk, texture, mouth feel and preservative qualities and contains only 1 calorie per gram (sugar contains 4 per gram), making it an effective substitute. It is commonly used as a replacement for sugar, starch, and fat in commercial beverages, cakes, candies, dessert mixes, breakfast cereals, gelatins, frozen desserts, puddings, and salad dressings. Because of it's high fiber content, it is often used to add fiber to foods.
