and the milk, yogurt, and cheese groups. In fact, carbohydrates are
abundant in all the groups of the food guide pyramid except

How does the nutrient affect the body?
The main role of carbohydrates is to provide energy to the
body. Carbohydrates are broken down into a form of sugar known as glucose.
Glucose is carried to every cell in the body by the blood and can be used
right away for energy.
Glucose can be combined into larger sugar units called
glycogen, which is a storage form of glucose. A certain amount of
glycogen is stored in the liver. It serves as an energy reserve until it's
needed by the body. To a lesser degree, glycogen is stored in muscles.
It is a key fuel source for the muscles, especially during exercise.
