What do proteins, carbohydrates, and fats do for your body?

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. Carbohydrates should be your body's main source of energy in a healthy, balanced diet. They're broken down into glucose (sugar) before being absorbed into your blood. The glucose then enters your body's cells with the help of insulin. Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.

proteins help the body to grow and develop, carbohydrates provide energy and fats also give energy to the body and support cell growth
