Sugar Question

Can anyone tell me the difference in the sugars and sugar alcohol in products. I've noticed when I buy some sugar-free products they have sugar alcohols in them. I'm not sure what that is or if it will cause dumping syndrome.

Here is some informations. I have a friend who can't eat sugar free popsicles because of the high sugar alcohol....she is a diabete. http://ific.org/publications/factsheets/sugaralcoholfs.cfm Hugs, Traci
