摘要
为了解广东大学生膳食硒的摄入状况，进而了解广州市居民的膳食硒摄入状况，采用单纯随机抽样的方法随机选取广东某高校某班学生10人，男女生各半，用双份饭法收集这10名学生连续7d内每天摄入的全部食物（包括饮水、饮料、零食等），共70份样品，用荧光分光光度法测定了各样品的硒含量，得到学生在调查期间膳食硒的摄入状况。结果表明，男、女生人均膳食硒摄人量分别为86．51μg／d和69．92μg／d，学生总体人均膳食硒摄入量为78．22μg／d。该校学生膳食硒的摄入量达到了中国营养学会推荐的参考摄入量（50—250μg／d）的要求。
To investigate the dietary selenium intake level of the campus students in a university in Guangzhou and estimate the dietary selenium intake of Guangzhou residents, 10 students including 5 boys and 5 girls were selected by random. Duplicate diet study method was conducted as diet survey method. 70 samples were collected in the study. The selenium content of the samples was analyzed. The results show that the average dietary selenium intake of the university students is 86. 51 μg/d by male, 69. 92 μg/d by female, and the total average value is 78.22 μg/d. Conclusion： The dietary selenium intake of the university students was met the reference intake value 50 - 250μg/d of the Chinese Nutrition Society.
