A 24-hour history was taken in a group of 169 children aged 9 and 14 years, randomly chosen from two primary schools in Białystok, and 186 children at the same age from three village primary schools. The results were compared to the recommended dietary allowances adequate to age and sex, and subjected to statistical analysis. The mean content of the respective vitamins in the diets of children living in town is higher than their mean content in the diets of village children. In many cases the results are statistically significant. The correction coefficient, allowing estimation of vitamin loss due to food processing was used to analyse the realisation of the vitamin dietary allowances in diet. The realisation of the recommended dietary allowances for the respective vitamins (in %) in the diets of 9- and 14-year old schoolchildren living in suburban areas is considerably lower compared to that noted in town.
