Sugar substitutes are ingredients used to provide sweetness without the calories of regular sugar. They can be natural, like stevia and honey, or artificial, such as aspartame and sucralose. These alternatives are popular among people looking to reduce sugar intake, manage weight, or control blood sugar levels. Many sugar substitutes are much sweeter than sugar, so only small amounts are needed. They can be found in various products, including soft drinks, baked goods, and tabletop sweeteners. While generally considered safe, some individuals may experience side effects or prefer to avoid certain substitutes for personal or health reasons.
