The content of copper, zinc and manganese in daily diets reconstructed in the laboratory in 1988 on the basis of data on the yearly food consumption in 1986 of two social groups (manual and mental workers) with medium income was determined. The diets were prepared for four regions of the country (Warszawa, Lublin, Poznan, Wroclaw). It was found out that the content of copper and zinc in the diets in 1986 and the realisation of recommended dietary allowances for these minerals were lower than in 1973, 1980 and 1981. The degree of realization of the recommended intake of zinc and copper in diets from 1986 was on average 67% and 45% respectively. The content of manganese in the diets was in the range of recommendation. The content of microminerals in the diets was usually similar in the all studied regions of the country.

Studies on the content of macrominerals in daily diets reconstructed in 1988 on the basis of the analysis of family budgets in 1986 carried out by the Central Statistical Bureau were carried on. Two social groups i.e. manual and mental workers with medium income were considered. The diets were prepared for 5 regions (Warszawa, Lublin, Olsztyn, Poznan, Wroclaw). According to the studies the requirements for calcium and magnesium were met in about 70% and those for iron in about 84%. The content of potassium in the diets was in the range of recommended allowances while the phosphorus exceeded the allowances by about 20-30%. The comparison of the presently studied diets with the ones from 1973, 1980, 1981 showed a lower degree of realization of the recommended intake of calcium and magnesium in 1986. The content of studied minerals in the diets was usually similar in all five regions.

The diets were prepared in laboratory on the basis of analysis of family budgets carried out by the Central Statistical Bureau in 1986. In the study two socioeconomic groups were considered: that is workers in industry and mental workers with medium incomes. For the preparation diets about 70 food products were obtained from retail sales in 1988. The diets were prepared for live regions of the normal recommended intake diets of energy and protein was realized in these diets in about 90%, and the requirements for fat were covered in 104% in the diets of workers and 114% in the diets of non-workers. The degree of realization of the recommended intake was similar to the results obtained in intake diets in 1973 and 1981, but lower than that in 1980. No diets related to the region of the country.
