Brown sugar, like all sugar, is a simple carbohydrate that provides quick energy (glucose) to the body and the brain. Glucose is the brain's preferred energy source. However, excess calories and carbohydrates from sugar and other sources are stored as fat. So it is important to consume sugar in moderation.
Common uses for brown sugar include sweetening baked goods, sauces, marinades, and even bacon. It's also made into a sugar syrup, often with spices, to flavor beverages. Brown sugar has also become a popular ingredient in body scrubs.
