The aim of the study is to assess the contents of iron, zinc and copper in the diet among of adolescents living in Warsaw. The intake ofselected trace elements was estimated on the basis of three-day dietary records. Microelement contents in the diet were calculated using Food Composition Tables. The percentage of the RDA realization for the safe level was calculated on the basis of standards for Polish population, developed by National Food and Nutrition Institute. It was demonstrated that adolescents living in Warsaw had 50-60% copper-deficient diets. The content of iron and zinc in the diet of adolescents was about 10-40% lower than recommended. Deficiency of iron in the body causes anaemia and influences learning process, therefore the content of this element in the diet of young people is especially important.
本研究的目的是评估居住在华沙的青少年饮食中铁、锌和铜的含量。根据三天的饮食记录估算所选微量元素的摄入量。饮食中的微量元素含量通过食物成分表计算得出。安全水平的推荐膳食摄入量（RDA）实现百分比是根据国家食品和营养研究所制定的波兰人群标准计算得出的。结果表明，居住在华沙的青少年有50 - 60%的饮食缺铜。青少年饮食中铁和锌的含量比推荐值低约10 - 40%。体内缺铁会导致贫血并影响学习过程，因此这种元素在年轻人饮食中的含量尤为重要。
