[Content of calcium and magnesium in daily food rations of children from two districts of southern Poland].

Calcium and magnesium content in daily diets for children of the range from 1.0 up to 14.6 years was examined. Children from Bielsko districts lived in villages near Zywiec and from Katowice districts lived in the city of Bytom. Results are grouped according to: 1 domicile (city-village), 2 age range 1.0-1.5, 3.5-4.5, 6.5-7.5, 11.4-14.6 years (in the range 11.4-14.6 also according to sex), and according to 3 qualitative evaluation of the diet (adequate, poor and inadequate). As can be seen from the presented results amounts of the two elements under study in the daily diets for children are incompatible with recommended nutritional standards. Discrepancies increased, when age of children was higher and when qualitative evaluation of the diet was poorer.
