For my health project I did carbohydrates. They are the bodies energy source.

Carbohydrates supply the body with the energy it needs to function. They are found almost exclusively in plant foods, such as fruits, vegetables, peas, and beans. Milk and milk products are the only foods derived from animals that contain a significant amount of carbohydrates.

Carbohydrates are divided into two groups, simple carbohydrates and complex carbohydrates. Simple carbohydrates, sometimes called simple sugars, include fructose (fruit sugar), sucrose (table sugar), and lactose (milk sugar), as well as several other sugars. Fruits are one of the richest natural sources of simple carbohydrates.

Complex carbohydrates are also made up of sugars, but the sugar molecules are strung together to form longer, more complex chains. Complex carbohydrates include fiber and starches. Foods rich in complex carbohydrates include vegetables, whole grains, peas, pasta, potatoes and beans.

Carbohydrates are the main source of glucose, which is a major fuel for all of the body's cells and the only source of energy for the brain and red cells. Except for fiber, which cannot be digested, both simple and complex carbohydrates are converted into glucose. The glucose is then either used directly to provide energy for the body, or stored in the liver for future use. When a person consumes more calories than the body is using, a portion of the carbohydrates consumed may also be stored in the body as fat.

When choosing carbohydrate-rich foods for your diet, always select unrefined foods such as fruits, vegetables, peas, beans, and whole-grain products, as opposed to refined, processed foods such as soft drinks, desserts, candy, and sugar.
