There are plenty of sweet foods on store shelves and in refrigerated display cases that don’t actually have sugar in them. Manufacturers make these foods with non-nutritive sweeteners—reduced-calorie, low-calorie and no calorie sugar substitutes. These sweeteners are created from alcohols, amino acids, and other chemical formulas that have been approved by the Food and Drug Administration (FDA) for dietary use.
Sugar alcohols are one type of reduced-calorie sweetener. Sugar alcohols provide a sweet taste with fewer calories per gram than table sugar (sucrose) and are commonly used in place of sugar and often in combination with artificial sweeteners. Contrary to their name, sugar alcohols are not sugar or alcohol the way we think of them. They do not contain the type of alcohol found in alcoholic beverages.
When you’re reading food labels, you’ll recognize sugar alcohols easily because their names always end in “ol”—sorbitol, xylitol, erythritol, maltitol, and mannitol. Keep an eye out for these because they should be used in moderation. Using large amounts of sorbitol (more than 50 grams a day) or mannitol (more than 20 grams a day) can cause abdominal gas, bloating, and diarrhea.
Low-calorie sweeteners are also known as sugar substitutes. They provide practically no calories and won’t increase your blood glucose levels. There are lots of them on the market these days. They can be used alone to sweeten foods and beverages such as iced tea or coffee, or as an ingredient in other products.
