Are Simple Sugars Carbohydrates?
Carbohydrates can be categorized into three major groups: dietary fibers, complex sugars–or starches–and simple sugars. Approximately 40 to 60 percent of your calorie intake should be comprised of carbohydrates, according to Medline Plus, a service of U.S. National Library of Medicine. A portion of those carbohydrates should come from natural sugars in fruits and dairy products, which are converted into glucose by the body to produce usable energy.
