The influence of dialysis's period on energy and selected nutrients intake was examined on 38 patients with end stage renal disease. The longer period of dialysis caused higher energy and protein content in daily food rations. Furthermore lower intake of energy, protein, iron and calcium were observed as well as too high level of saturated fatty acids comparing to recommendations. Our data strongly suggest that constant dietician care might be essential to correct nutrients intake and prevent possible deficiencies among patients with the end stage renal disease.
