Selenium intake and urinary and fecal Se excretion of 10 healthy men from a low Se area in China were determined for three consecutive days, in summer, fall, and winter of 1983, and the spring of 1984 while self-selected diets were being consumed. Mean daily Se intake was 8.8 micrograms/day with a range of 2.3-35.5 micrograms/day, and was far below the recommended range of safe and adequate Se intake of 50-200 micrograms Se/day (National Academy of Sciences/National Research Council). Mean urinary and fecal Se outputs were 3.7 and 3.4 micrograms Se/day, respectively. Mean Se balance during this time was +1.8 micrograms Se/day. Apparent absorption of Se approximated 57%. The low Se intake in this area is a cause for concern since the residents of Molimo may be at risk for Se deficiency diseases.
1983年夏季、秋季、冬季以及1984年春季，在中国一个低硒地区，连续三天测定了10名健康男性的硒摄入量以及尿硒和粪硒排泄量，期间他们食用自行选择的饮食。平均每日硒摄入量为8.8微克/天，范围在2.3至35.5微克/天之间，远低于美国国家科学院/国家研究委员会推荐的50至200微克硒/天的安全且充足的硒摄入量范围。平均尿硒和粪硒排出量分别为3.7微克硒/天和3.4微克硒/天。在此期间，平均硒平衡为+1.8微克硒/天。硒的表观吸收率约为57%。该地区硒摄入量低令人担忧，因为磨立莫的居民可能有患硒缺乏疾病的风险。
