Sucrose, or table sugar, is one of the most widely used ingredients in the foods we buy. We compare the sweetness of all other sweeteners to sugar, which is classified as a "nutritive sweetener." Nutritive sweeteners not only add flavor to our foods, but they also provide calories from carbohydrates. They are found naturally in some foods, like fruit and milk, and are added to other foods. Other nutritive sweeteners found on ingredient labels include fructose, dextrose, lactose, maltose, honey, corn syrup, high-fructose corn syrup (HFCS), molasses, invert sugars, concentrated fruit-juice sweeteners, sorbitol, mannitol, xylitol, and other sugars.
