Artificial Sweeteners (cont.)

What are sugar alcohols?

Sugar and sugar alcohols are each considered nutritive sweeteners because they provide calories when consumed. Sugar alcohols, or polyols, contain fewer calories than sugar. Sugar provides 4 kcal/gram, and sugar alcohols provide an average of 2 kcal/gram (range from 1.5 kcal/gram to 3 kcal/gram). Contrary to their name, sugar alcohols are neither sugars nor alcohols. They are carbohydrates with structures that only resemble sugar and alcohol.

Foods that contain sugar alcohols can be labeled sugar-free because they replace full-calorie sugar sweeteners. Sugar alcohols have been found to be a beneficial substitute for sugar for reducing glycemic response, decreasing dental cavities, and lowering caloric intake.

Sugar alcohols naturally occur in many fruits and vegetables but are most widely consumed in sugar-free and reduced-sugar foods. The sweetness of sugar alcohols varies from 25% to 100% as sweet as table sugar (sucrose). The amount and kind being used will be dependant on the food. The following table lists the details on each of the sugar alcohols.
