Dietary intakes of Mg, Ca and P with whole-day food rations from Cracovie, Lodz, Olsztyn and Poznan, Poland.
Magnesium, calcium and phosphorus have been determined in whole-day food rations collected during three consecutive days in winters of 1993/4, 1995 and 1996 in hospital canteens in Krakow, Lodz, Olsztyn and Poznan, Poland. Portions of food for one person were collected. In 1998 whole-day food rations of seven students (five consecutive days) and, in 1999, of eight adults (three consecutive days) were also prepared for Mg, Ca and P determination. Mg and Ca were determined by ASA and P by colorimetric method. The diets collected at hospital canteens were deficient in magnesium but not in calcium. Duplicate diets did not supply enough magnesium and calcium. All the whole-day food rations contained 2-4-fold excess of phosphorus. Such a composition of macroelements in food can pose a threat to human health.
