Sugar alternatives are substances used to sweeten food and drinks without the calories of traditional sugar. Common types include stevia, aspartame, and sucralose. These alternatives can be derived from natural sources, like plants, or created synthetically. They are often much sweeter than sugar, so only small amounts are needed. Many people choose sugar alternatives to reduce calorie intake or manage conditions like diabetes. While some alternatives may have little to no effect on blood sugar levels, others can still impact health. It's important to read labels and understand the ingredients in products containing these sweeteners.
