Sugars are a kind of carbohydrate.
Carbohydrates include sugars, starches, cellulose, and other compounds. An essential nutrient, carbohydrates are the human body's main source of both quick and sustained energy.

You will see it listed as honey, raw sugar, turbinado sugar, brown sugar, confectioner's sugar, powdered sugar, fructose, dextrose, glucose, molasses, corn syrup, maltose, sucrose, xylitol, or mannitol.
