sugar substitute

Any of a group of carbohydrates (e.g., fructose, sorbitol and xylitol) which are of potential use as replacements for the usual dietary sugars—glucose and sucrose—in diabetics, as such substitutes do not require insulin for certain steps in their metabolism. However, the efficacy of sugar substitutes in reducing serum glucose is suboptimal, as the diabetic liver converts a significant portion of fructose and its metabolites into glucose.
