Sugar is a sweet-tasting, carbohydrate-rich substance commonly derived from sugarcane or sugar beets. It is widely used as a sweetener in food and beverages, adding flavor and energy. Sugar comes in various forms, including granulated, powdered, and liquid, each suited for different culinary applications. Beyond its culinary use, sugar also has roles in preserving food and enhancing texture, but excessive consumption can lead to health concerns like obesity and diabetes.
