Our daily food choices resupply the potential energy, or fuel, that the body requires to continue to function normally. This energy takes three forms: carbohydrate, fat, and protein. (See table 2.1, Estimated Energy Stores in Humans.) The body can store some of these fuels in a form that offers muscles an immediate source of energy. Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the bodyâs principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
When it comes to carbohydrates, there are simple forms and complex forms. Carbohydrates power the body as the primary energy source and should make about 40 to 60 percent of a person's daily nutritional intake. The various parts of carbohydrates -- starch, fiber and sugar -- have distinct jobs in the body.Carbohydrates are found naturally in fruits, vegetables and grains.ugar. Sugar is considered a simple carbohydrate. It is the basic building block of molecules for every type of carbohydrate. Unlike fiber and starch, it breaks down quickly and easily into glucose which is used by the body as a primary energy source.
