Sugar is a sweet-tasting carbohydrate, primarily derived from sugarcane or sugar beets. It is commonly used to sweeten food and beverages, and comes in different forms such as granulated sugar, brown sugar, powdered sugar, and liquid sugar.

Sugar is a key ingredient in many culinary applications, including baking, desserts, beverages, and preserves. It provides a quick source of energy, but should be consumed in moderation due to its potential link to health issues like obesity, diabetes, and heart disease when consumed in excess. Natural sugars are found in fruits, vegetables, and dairy, while refined sugars are processed and added to food products.
