How and why the rightfoods in the right proportions — help you feel more energetic, look better and live longer.
To have the necessary energy and strength to get through each day and still
have reserves left over, you must eat right. Some foods, because of their
chemical composition, are more easily converted by the body into energy for
your muscles than are others; still other foods contain nutrients that are
especially important for the growth and maintenance of teeth and bones, and
for the functions of the heart, lungs, eyes and other organs.
Food consists of carbohydrates, fats and protein, known collectively as the
macronutrients, and much smaller quantities of vitamins and minerals, or the
micronutrients. Water is a third type of nutrient in food. The macronutrients
are used for energy and to maintain, repair and rebuild the different parts
of your body. Most vitamins and some minerals help regulate chemical processes
that take place inside your body; other minerals are involved in the formation
of all your tissues, including your bones, teeth and blood. One of the most
crucial functions of water is to provide fluid for your blood's circulation.
