[Assessment of the content of antioxidant vitamins in respective seasons of the year in diets of junior high school adolescents living in Bialystok].Przegl Lek. 2003; 60 Suppl 6:57-9.PL
Many ailments due to improper diet in childhood turn out to be civilization diseases in adults. Therefore, the assessment of nutrition state and eating habits, apart from a variety of food components, should also refer to vitamin consumption. A particular attention should be given to antioxidant vitamins. The aim of the study was to analyse the content of vitamins A, E and C, according to the season of the year, in the diets of junior high school adolescents from Białystok. The study involved adolescents of both sexes, aged 13-15 years, chosen by collective randomisation. Eating habits were assessed using the method of the 24-hour dietary history prior to the investigation as recommended by the institute of Food and Feeding in Warsaw. The vitamin content in the menu was calculated with a computer programme FOOD2. The results were compared with a daily norm recommended for sex and age, and subjected to statistical analysis with the t-Student test. The content of vitamins A and E in the diets of adolescents in the respective seasons largely exceeds the norm, which may be related to higher fat consumption than recommended. The content of vitamin C in the menu also goes beyond the recommended norm. In the diets of girls in spring the norm was exceeded twice.
