摘要
将维生素C(VC)营养水平近似的26名60～70岁男性健康老人分为四组,每人每日分别摄入VC 59、94、149及223mg,历时15天,使机体饱和。测定饱和期前后的清晨空腹一小时尿及四小时负荷尿VC含量。测得VC的适宜需要量约为95mg,而饱和需要量略高于223mg。
Twenty six healthy males, 60-70 years old, having the same vitamin C nutritional status detected by saturation test were selected for this study. They were divided into 4 groups and supplemented orally with various amounts of vitamin C for 15 days. The intake of each group was 59, 94, 149 and 223 ing/day per capita respectively. After comparing the vitamin C contents of 4-hour saturation test urine and early morning 1 hour fasting urine at the end of the experiment, it seems that the optimal daily requirement for the elderly is about 95 mg, and the saturated daily requirement is a little higher than 223 mg.
