that are vital for life. The proteins of muscles, the hor-<br >mones, the enzymes, the fats, and the stored forms of<br >sugar are examples of such necessary compounds. As a<br >result of these complex reactions, chemical waste prod-<br >ucts are produced as well and must be eliminated from<br >the body. And, of course, all-important energy is either<br >stored or released as these reactions are taking place.<br >What is energy? Energy is simply the ability to do work.<br >Today we talk about the energy value of foods and about<br >the number of calories that a particular food provides.<br >The calorie is a unit of heat energy; that is, it measures<br >energy as a form of heat. The energy value of individual<br >fbods depends on the amount of carbohydrates, fats, or<br >proteins present.

A milligram (mg) is<br >1./1,000 of a gram; a microgram (pg) is 1/1,000,000 of a<br >gram, or 1/1,000 of a milligram.<br >Different types of energy are interchangeable. For<br >example, the chemical energy of carbohydrates, which<br >are important body fuels, can be converted into heat<br >energy to help maintain a constant body temperature. It<br >can also be changed to kinetic energy necessary for<br >muscle action and physical activity, or it can be trapped<br >as chemical energy in other body compounds.<br > The Essential Nutrients<br > As the science of chemistry developed in the 18th and<br > 19th centuries, so did procedures to analyze what we<br > eat. Scientists soon discovered the great variety ot<br >
