The vitamin intakes of 77 men and 187 women aged 65 and over living at home were studied using seven-day dietary records. Intakes of ascorbic acid were below 10 mg/day in 5 per cent 25 per cent of men and 33 per cent of women took less than 50 i.u./day of vitamin D. Intakes of other vitamins (vitamin A, thiamine, riboflavin, nicotinic acid, pyridoxine, and folate) were, in general, adequate, except for small numbers of subjects. The findings are compared with those of the Panel on Nutrition of the Elderly (1972).
采用七天饮食记录法,对77名65岁及以上居家男性和187名65岁及以上居家女性的维生素摄入量进行了研究。5%的男性和25%的女性抗坏血酸摄入量低于10毫克/天,33%的女性维生素D摄入量低于50国际单位/天。除少数受试者外,其他维生素(维生素A、硫胺素、核黄素、烟酸、吡哆醇和叶酸)的摄入量总体充足。研究结果与老年人营养问题专门小组(1972年)的研究结果进行了比较。
