title: The content of trace elements in the diet of adolescents in Warsaw.
abstract: 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.
