What are Sugar Alcohols?
The term "sugar alcohol" is very misleading. Sugar alcohols get their name from their unique chemical structure, which resembles both sugar and alcohol. But they're neither sugars nor alcohols. In fact, sugar alcohols are a type of carbohydrate that sweetens foods, but with half the calories of sugar. There are several specific types of sugar alcohols (usually ending with the letters "-ol"). When reading a food label, the following ingredients are actually sugar alcohols:
- Hydrogenated starch hydrolysates
Why Use Sugar Alcohols?
You may wonder why manufacturers would put sugar alcohols in foods and other products, or why people might seek them out. Here are a few reasons why consumers choose these products:
- Fewer calories. Sugar alcohols contain fewer calories (0.2 to 3 calories per gram) than sugar (4 calories per gram) does, making them a diet-friendly choice for people who want to limit their caloric intake, but still enjoy sweet foods.
- Safe for diabetics. Sugar alcohols are absorbed more slowly (and incompletely) by the body. Unlike regular sugar, they require little or no insulin for metabolism. *People with diabetes should consult their physician, dietitian or other health professional about incorporating sugar alcohols into their daily meal plans.
- Better dental health. Sugar alcohols do not promote tooth decay since they are not metabolized by the bacteria that produce dental cavities.
- Fewer drug interactions. Sugar alcohols do not react with the pharmacologic ingredients in medicines as much as sugar sometimes can.
- Individual tastes. The different types of sugar alcohols vary in sweetness, from being about half as sweet to equally sweet as sugar.
- Sugar alcohols do not lose their sweetness when heated.
- Sugar alcohols do not absorb water like sugar does. Therefore the surface of foods made with sugar alcohols won't become sticky as quickly as products made with sugar.
- Molds and bacteria do not grow and multiply on sugar alcohols as well as they do on sugar.
- They can use a combination of sugar alcohols, sugar and/or artificial sweeteners to give the most pleasant taste, appearance, and texture to a food product.
Sugar alcohols have been used for years. After careful review, scientists have concluded that they are safe for human consumption. In the United States, the Food and Drug Administration (FDA) classifies some sugar alcohols as Generally Recognized as Safe (GRAS) and others are approved as "food additives."
However, there are a few things to keep in mind when it comes to pregnancy and children. Women with gestational diabetes, diabetes mellitus, or insulin resistance related to other medical conditions should limit their intake of nutritive sweeteners like sugar alcohols. Likewise, because sugar alcohols may bypass initial steps in digestion (similarly to fiber), excess intake may trigger gas production or a laxative effect and can even cause diarrhea-especially in children.
Whether or not you will experience problems will depend on your individual sensitivity level and the other foods you consume at the same time. It is best to find your individual tolerance level when using these food ingredients, and to avoid them if they cause discomfort.
