Food is essential for the maintainance of all functions of the body, and a correct and balanced diet for children is especially important due to their greater rate of growth, development and larger metabolic necessities. This study is based on the explanation of the concept of „nutritional status“ and the role of diet as one of its most important factors. Correct dietary habits are created in early childhood, therefore children that develop them earlier have a smaller risk of maturing chronic diseases linked to an incorrect dietary regimen. The purpose and aim of this study is to bring consciousness about the importance of an accurate diet for the growth, development and health of a child. There's an ever-greater incidence of obesity as a contemporary problem that an increasing number of children and adults have to face, and the number of overweight people is drastically increasing. A particular stress is put on the dietary standards and regulations for planning children's diets in kindergartens, which concern the composition and type of ingredients, the preparation of meals and the combination of ingredients. In order to determine the nutritional status the research has been conducted in the „Šegrt Hlapić“ kindergarten in Sesvete in two educational groups of pre-school age. Of the 45 predicted participants, only 38, which comprehended a sample of 20 girls and 18 boys, took part in the examination. Results of anthropometric measurements of body mass and height, from which the body-mass index was calculated were used to determine the nutritional status and nutritional grade of the children involved. The results of the study conducted have shown how ten children in total, i.e. one in four children, deviate from the normal nutritional status.
