Sugar is a sweet, crystalline substance derived primarily from sugarcane and sugar beet plants. It is widely used as a sweetener in a variety of foods and beverages, enhancing flavor and providing energy in the form of carbohydrates. Sugar comes in different forms, including granulated sugar, powdered sugar, brown sugar, and liquid syrups like honey and maple syrup. It is an essential ingredient in baking, cooking, and candy making, and is also used to preserve fruits and other food items through processes like jam-making. While sugar adds sweetness and richness to food, it should be consumed in moderation, as excessive intake can lead to health issues such as obesity, diabetes, and tooth decay.
