Consumption of sugar alcohols affects blood sugar levels, although much less than does sucrose comparing by glycemic index.

Sugar alcohols are usually incompletely absorbed into the blood stream from the small intestine which generally results in a smaller change in blood glucose than “regular” sugar sucrose.
