Hershey's Sugar Free Candies have fewer calories compared to their"regular" counterparts. However, they contain about the same level of fat as regular chocolate. Hershey's Sugar Free items contain sugar alcohols such as maltitol to replace the sugar. These sugar alcohols are digested more slowly and generally cause a relatively small rise in blood sugar levels. For people with diabetes, this is preferable to the sharper increase in blood sugar associated with products containing sugar.
