Fats are greasy substances that are not soluble in water. They are soluble in some solvents such as ether, benzene, and chloroform. They provide a more concentrated source of energy than carbohydrates. Fat-rich foods are generally more expensive than carbohydrate-rich foods. Fats are composed of carbon, hydrogen, and a proportionately smaller amount of oxygen (Townsend 78).

Fats can be found in both plant and animal foods. Plant foods include oils, made from sunflowers, sesame seeds, corn, peanuts, or soybeans. Nuts are another rich source of fats. Animal foods include fatty meats like bacon, sausage, fatty fish such as tuna and salmon. Milk and egg yolks are also high in

Monosaccharides are the least complex form of carbohydrates. They are sweet, call for no digestion, and can be absorbed directly into the bloodstream beginning at the small intestine. They include glucose, fructose, and galactose.

“In addition to providing energy, fats are essential for the function and structure of body tissues. Fats are a necessary part of cell membranes (cell walls). They contain essential fatty acids and act as carriers for fat-soluble vitamins. The fat stored in body tissues provides energy” (79).

Sucrose is composed of glucose and fructose. It is the form of carbohydrate current in granulated, powdered, and brown sugar and in molasses. It is one of the sweetest and least costly sugars. Its sources are sugar cane, sugar beets, and the sap from maple trees.

The quality and classification of a protein depend on the number and types of amino acids it contains. There are 20 amino acids, but only 9 are considered essential to humans (Taylor 24). Essential amino acids are necessary for normal growth and development and must be provided in the diet. Proteins containing all the essential amino acids are of high biologic value and are called complete proteins. The nonessential amino acids can be produced in the body if an adequate supply of amino nitrogen is provided in the diet (94).
