Aspartame is an artificial sweetener used in many diet foods and drinks. It's much sweeter than sugar but has very few calories. Think of it as a sugar substitute for people watching their weight. It's found in diet sodas, sugar-free gum, and other low-calorie products. Unlike sugar, it doesn't raise blood sugar levels significantly. Aspartame is like the magical ingredient that makes diet soda taste sweet without the calories.
