This document discusses alternative sweeteners that can be used in place of sugar. It describes two groups of alternative sweeteners: non-nutritive sweeteners like aspartame and sucralose that provide no calories, and nutritive sweeteners like sorbitol and maltitol that contain calories but have less effect on blood glucose than sugar. While alternative sweeteners can add variety to a low-calorie diet, some may cause digestive issues and products containing them still need to be monitored for fat and fiber content.
