Vitamins: Helpful or harmful?
1984
Kesselman, Shirley
Vitamins are essential for health. The body requires small amounts of vitamins to function properly. Vitamins are metabolized, not digested, and aid in the production of energy and tissue growth. Vitamins are classified as fat soluble (vitamins A, D, E, and K), and water-soluble (all others). There is no metabolic difference between synthetic and "natural" vitamins. Recommended Dietary Allowances (RDA) are established for most vitamins. Excess doses or megadoses of vitamins may be harmful to the body, however, there are certain times in one's life when more than the usual amount of vitamins are recommended, such as pregnancy. At those times, vitamin supplements may be necessary and should be taken under a doctor's supervision. The possible effects of megadoses are discussed, including poisoning from excess intake of vitamin A. Vitamins can be obtained from a variety of foods, but preparation and storage of the food affects the vitamin content. Suggestions are given on how to purchase and prepare food to retain their vitamins along with a chart that discusses 13 vitamins. (kbc)
