The studies on content of basic nutrients, selected minerals and vitamins in daily food rations among children and teenagers aged 7 to 18, living in one of the Poznań orphanage, in four seasons were carried out in the period between July 2007 and May 2008. The eating habits were assessed on the basis of stock reports (ten-day menu). On the basis of the obtained findings the improper distribution of energy provided with individual components was stated. The content of energy differed from the recommended values (about 24%), proteins (about 102%), fat (about 28%) and cholesterol (about 45%). The study showed too high intake level of zinc (about 47%), copper (about 71%), vitamin A (102%), B-group vitamins (44% to 163%) and too low intake of potassium, calcium and vitamin C (about 20%). The research did not find any statistically significant relationships between the consumption of individual nutrient elements and seasons.
