What are carbohydrates?

Carbohydrates are sugars in food. Carbohydrates also are the parts of food that the body doesn't digest, called fiber. Carbohydrates are naturally found in fruits, vegetables, nuts, seeds, grains and dairy products.

Carbohydrates also may be added to processed foods. For example, fructose is a type of carbohydrate in fruit, but it can be processed and used to sweeten drinks. Inulin is a fiber found in some fruits and vegetables but also may be added to grain products and protein bars.
