Sugar Alcohols

Consumption of sugar alcohols does affect blood sugar levels, although less than that of "regular" sugar (sucrose). Sugar alcohols may also cause bloating and diarrhea when consumed in excessive amounts. Some people it doesn't have to be excessive amounts to cause these side effects.

They are found in all kinds of sugar free products including but not limited to chewing gum, candies, LC shakes, LC bars etc. Here is a list of sugar alcohols, there are probably more.

When you're considering foods with low- or reduced-calorie sweeteners, always check the Nutrition Facts on the label. Many of the food products containing these types of sweeteners may still have a significant amount of carbs.

When I look at a nutrition facts label I always avoid anything that has an -tol at the end of it (I'm not going to memorize that LIST!!) because that's usually a sugar alcohol and for some of us, we process them exactly like carbs.
