Abstract

In general, low dietary intakes can account for much of poor vitamin nutriture reported among various elderly populations. Despite problems in assessing vitamin nutriture in the elderly, the 1980 RDAs for thiamin, riboflavin, and ascorbic acid seem appropriate for those populations. However, RDAs for vitamin A and folate may be too high and the RDAs for vitamin D, vitamin B-6, and vitamin B-12 may be too low, due to specified age-related changes in the metabolism of these vitamins. For vitamin E, vitamin K, niacin, biotin, and pantothenic acid, the data is conflicting and/or insufficient to make a judgment about the appropriateness of the RDAs or to estimate safe and adequate daily intakes for the elderly.

摘要

一般来说，饮食摄入量低可解释各类老年人群中所报告的维生素营养状况不佳的大部分情况。尽管在评估老年人的维生素营养状况方面存在问题，但1980年制定的硫胺素、核黄素和抗坏血酸的膳食营养素参考摄入量（RDA）似乎适用于这些人群。然而，由于这些维生素代谢中特定的年龄相关变化，维生素A和叶酸的RDA可能过高，而维生素D、维生素B - 6和维生素B - 12的RDA可能过低。对于维生素E、维生素K、烟酸、生物素和泛酸，数据相互矛盾和/或不足，无法判断RDA是否合适，也无法估计老年人的安全和充足每日摄入量。
