为保证驻高原部队战士维生素C的营养需要而进行维生素C需要量研究, 为制定高原特殊环境部队人员维生素C供给量标准提供依据。选择进驻高原1～3年的青年男性战士50 名, 分为5 组, 每组10 名。第1～5 组每人每日维生素C摄取量为20、40、60、80和110m g, 在实验期间膳食维生素C摄取进行严格控制。实验期为24天。以空腹血浆维生素C含量, 24小时尿总维生素C排出量, 口服500m g 维生素C4小时尿中排出量等三项为评价指标。于实验等14 天测定, 第4组以上三项指标均达到标准要求。结果表明: 久居西藏高原部队战士维生素C需要量为80m g, 供给量为96m g。本实验结果揭示久居高原战士维生素C需要量要高于平原地区
In order to ensure the nutritional needs of vitamin fighters in the plateau units, vitamin C requirements were studied, which provided the basis for formulating the standard of vitamin C supply for special environmental units in the plateau. Fifty young male soldiers who entered the plateau for 1-3 years were divided into 5 groups of 10. The daily intake of vitamin C in groups 1 to 5 was 20, 40, 60, 80 and 110 m g per day. The intake of dietary vitamin C was strictly controlled during the experiment. The experiment period is 24 days. To fasting plasma vitamin C content, 24-hour total urinary vitamin C excretion, oral administration of 500g g of vitamin C4 hour urinary excretion and other three indicators for the evaluation. 14 days in the experiment and other tests, the first four groups of indicators have reached the standard requirements. The results showed that the vitamin C content of soldiers living in Tibet Plateau for a long time was 80 m g and the supply was 96 m g. The results of this experiment reveal that the long-serving altitude warrior vitamin C requirement is higher than the plain area
