title: [Calcium and phosphorous content in daily rations of adolescents from Biała Podlaska District].
abstract: The aim of the study was to assess the Ca and P intake and Ca:P ratio in daily rations of boys and girls aged 10-15 years. Calcium intake amounted to 51% and 65% of safe intake level of RDA for 10-12 and 13-15 years old boys and 43% and 44% for girls, respectively. Phosphorus intake exceeded the RDA and amounted to 141-165% for boys and 122-133% for girls. It is suggested that persisting disproportions in Ca:P ratio (> or = 1:1,26) in daily rations may have disadvantageous effect on Ca metabolism, particularly in girls. A permanent nutritional education of children stressing the impact of proper nutrition on health, seem indispensable.
