Sugar is a sweet, crystalline substance found in many foods and drinks. It is primarily derived from sugarcane and sugar beets and exists in various forms, including white sugar, brown sugar, and powdered sugar. The most common type is sucrose, but other forms include glucose, fructose, and lactose. Sugar is widely used in baking, cooking, and processed foods to enhance flavor and texture. However, excessive sugar consumption is linked to health issues like obesity, diabetes, and tooth decay. Natural sugars in fruits and dairy products are healthier alternatives. Reducing added sugar intake by choosing whole foods and reading nutrition labels can promote better health. Moderation is key to enjoying sugar while maintaining a balanced diet.
