Magnesium, calcium and phosphorus contents in daily food rations in primary school children: questionnaire and analytic studies.
Aims of the performed studies included working out a technique of determining representative rations on the basis of questionnaire studies on school children in Wielkopolska west region of Poland. The reconstructed representative daily food rations provided grounds for analytic studies. The studies were performed in the four seasons of the year. The studied food rations failed to cover the recommended daily intake of Mg and Ca. On the other hand, the daily intake of P transgressed the food norms. The inadequate Ca to Mg and Ca to P ratios were interpreted as deserving special concern when confronted with the market situation in Poland and as creating particular health hazards for the studied school children. The employed statistical analysis demonstrated that the suggested technique of determining representative rations may be employed in evaluation of Mg, Ca and P intake.
