Dietitian Brenna at Eating Simple recently posted an article on artificial sweeteners exclusive of sugar alcohols. Now she’s reviewed sugar alcohols. Many who have a sweet tooth, including myself, use sugar substitutes such as sugar alcohols. Sometimes they affect blood sugar levels, although not as much as sugar.
Dr. Maria Collazo-Clavell at the Mayo Clinic wrote about use of artificial sweeteners by people with diabetes. Like Brenna, she notes that sugar alcohols can raise blood sugar levels in people with diabetes. The Mayo Clinic has another article on sugar substitutes.

Moderate use of xylitol appears to have a role in preventing tooth decay. Check out the blog od Dr. Ellie Phillips.
