Sugar alcohols are among the sugar substitutes. That is, they have a similar sweetening power to sugar, but contain fewer calories. Sugar substitutes should not be confused with sweeteners, which usually have a significantly higher sweetening power, but are completely or practically calorie-free.
Sugar substitutes include fructose, sorbitol, xylitol, maltitol and mannitol, among others. Some of them are naturally contained in various foods. But they are also manufactured industrially.
Unpleasant side effect: bloating
The sugar alcohols differ in their sweetening power, but usually sweeten weaker than table sugar (sucrose). Even in relatively small quantities, they can provoke flatulence, diarrhea and even abdominal cramps.
In addition, the body uses sugar alcohols predominantly independently of insulin. Therefore, in the old days they often served as a component of diabetic food.
