摘要: 随机采购南京市农贸市场出售的粮食类食物、动物性食物、水果和蔬菜等,采用原子荧光光度法测定了各种食物的含硒量。结果表明:动物性食物含硒量高于植物性食物,尤以动物内脏含硒量为最高;禾谷类和豆类食物的含硒量又比水果和蔬菜高,多数食物含硒量小于全国代表值。调查了南京市居民的日常饮食,根据现代营养原理制定了膳食结构,对该膳食结构进行硒营养评价,计算南京市居民日常硒的摄入量、结果表明:南京市居民硒摄入量为30.4μg/d,与中国营养学会推荐的硒摄入量的最低限值50μg/d相差甚远,日常膳食不能满足人体对硒的最低需要,开发高效安全的补硒食品势在必行。

Abstract: The Selenium contents of foods including cereals.animal foods,fruits and vegetables of Nanjing agricultural market were determined by Atomic Fluorescence Spectrormeter (AF-610A).The results showed that animal foods especially pork liver contained the highest selenium content at 0. 1 835±0.1834 μg/g.cereal foods contained higher selenium content at 0.0309±0.0139μg/g in comparison with vegetables at 0.008±0.007 μg/g and fruits at 0.006±0.005 μg/g.The food selenium intake of Nanjing inhabitants was 30.8 μg/day compared with suggested selenium intake of 50~200 μg/day set by Chinese National Nutrition Association.The low selenium intake might increase the risk of selenium deficient disease and show harmful health etTect.The Se-enriched foods are necessary to be developed to increase the selenium intake of Nanjing inhabitants.
