What are sugar alcohols?
The term “sugar alcohol” is misleading. Neither a sugar nor an
alcohol, sugar alcohols are a type of sweetener used in foods labeled
"sugar-free." You'll find them in chewing gum, sugar-free candies, cookies,
soft drinks, and other foods. Sugar alcohols have about half to one-third fewer
calories than sugar.
For example, if a food label doesn't list sugar as an ingredient,
but it has 20 grams of sugar alcohol, that is equal to about 10 grams of
sugar.
Sugar alcohols occur naturally in plant foods, such as berries and
fruits. Common names for sugar alcohols are sorbitol, xylitol, mannitol,
lactitol, isomalt, maltitol, and hydrogenated starch hydrolysates (HSH).
What are sugar alcohols used for?
Sugar alcohols not only sweeten diet foods, they are also used in
chewing gums, toothpaste, and mouthwash. People who have diabetes eat foods
made with sugar alcohols because they turn to glucose more slowly and don't
cause sudden increases in blood sugar.
Sugar alcohols used in chewing gum do not cause tooth decay.
If foods are "sugar-free," does this mean I can eat all I want?
No. People with diabetes still need to be careful when eating foods
made with sugar alcohols because they still contain carbohydrate.
If you have diabetes, read food labels closely to determine the
amount of carbohydrate in each serving of food containing sugar alcohol.
Although sugar alcohols don't cause sudden spikes in blood sugar, they do have
some effect on it. Artificial sweeteners, on the other hand, are calorie-free
and have no effect on blood sugar.
Are there risks from eating too much sugar alcohol?
Sugar alcohols can cause diarrhea, bloating, and weight gain if you
eat too much of them.
