This article is the second part of the review of the studies on nutrition in Polish preschool children. In the first part, studies on preschool menus assessment were presented and summarised, whereas this article reviews the studies on the assessment of foods and meals prepared at preschool. The aim of this review was to present and summarise the results of the studies on the assessment of meals prepared for children at preschool based on the reports from the preschool food storeroom, the studies on chemical analysis of sample meals served at preschools and the studies on comparison of the results of chemical analysis to the results obtained by calculations obtained from computer programmes. The results of the studies on the assessment of meals prepared for children at preschool using various methods confirm most of the findings from the studies on the assessment of preschool menus. It is necessary to carry out more studies on energy and nutrient content assessment of preschool meals determined by chemical analysis of sample meals in order to provide more accurate information about the real nutritional value of meals served to children at preschool. It is essential to update the Polish food composition tables to enable more precise calculations of nutritional value of the meals planned for children at preschools which will improve the possibility of adjusting preschool meals to the real needs of both 3-year-old and 4-6-year-old children during their stay at preschool.
