Carbohydrates are starches or sugars that fuel all
of the cells in the body. Common sources of carbohydrates are potatoes, beans, cereals, fruit, and milk. Both starches and sugars ultimately yield glucose. Cells convert glucose to energy or store excess glucose, called glycogen, in the liver and muscles. If the excess glucose exceeds a certain point, the excess glucose is converted to fat and stored.

Proteins are abundant in all living organisms.
Structural proteins make up the fingernails, skin,
bones, and teeth in humans. Other proteins regulate
metabolism, produce movement, and transport oxygen
and other substances in and out of body cells.
Common sources of protein are meat, cheese, beans,
nuts, and fish.

function in cellular structure, composition, and transport. Containing approximately twice the caloric value of carbohydrates, fats are found in butter, cream, eggs, and most cheese.

Vitamins are other organic substances required in
small amounts to maintain normal health. Most animals
cannot manufacture many vitamins themselves and must have adequate amounts in the diet.
