Sucralose is a zero-calorie artificial sweetener derived from sugar (sucrose). It is about 600 times sweeter than sugar and is widely used in food and beverages, including diet sodas, baked goods, chewing gum, and tabletop sweeteners (e.g., Splenda).
Sucralose is heat-stable, making it suitable for cooking and baking. It is not metabolized by the body, so it passes through the digestive system without adding calories or affecting blood sugar, making it popular for diabetics and low-calorie diets.
It is generally recognized as safe (GRAS) by major health authorities, though some studies have raised questions about its effects with long-term high consumption.
