For good health, consult the "Vita-menu"
Vitamins are important nutrients contained in the foods we eat. There are 13 different ones in all, and each plays its own special role in promoting bodily health. A continued deficiency at any stage of life of any one of this “baker’s dozen” can have serious consequences. Vitamins also work together in groups, sharing in the performance of numerous tasks relating to growth, reproduction and many other vital functions. So, in addition to getting enough of each vitamin, good health depends on achieving and maintaining a properly balanced intake of them all. Random “mega-dosing” (taking ten or more times the Recommended Daily Allowance, or RDA) of one or more vitamins can do more harm than good.
Who needs to supplement
Most healthy people who eat nutritious, sensible, balanced meals get enough vitamins from diet alone. For people with special needs, however, supplementation may be desirable. Included in this group gene
- Strict dieters
- Heavy drinkers
- Patients recovering from surgery or an illness
- Pregnant or breast-feeding women
For these people, taking a daily multivitamin supplement-one that does not exceed the RDA-may provide some extra insurance and is not harmful
