A variety of food supplements were taken by 66 percent of the elderly persons in this study. Ascorbic acid and vitamin E were the most popular choices. Some supplements may have improved nutritional status, while others were probably inappropriate or unnecessary. The findings indicate that the elderly have a number of erroneous beliefs about the efficacy of food supplements. Reasons for supplementation were often inappropriate, and unreliable sources of information were used. In addition, substantial amounts of money were spent on food supplements by those already existing on a limited budget. Nutrition education is needed to demonstrate the relationship between adequate diet, good health, and appropriate versus inappropriate food supplement consumption.
本研究中66%的老年人服用了多种膳食补充剂。抗坏血酸和维生素E是最受欢迎的选择。一些补充剂可能改善了营养状况，而另一些可能不合适或不必要。研究结果表明，老年人对膳食补充剂的功效存在一些错误观念。补充的原因往往不恰当，且使用了不可靠的信息来源。此外，那些本就预算有限的人还在膳食补充剂上花费了大量金钱。需要开展营养教育，以说明合理饮食、健康与恰当或不恰当食用膳食补充剂之间的关系。
