The paper deals with the topic of eating habits of preschool children. The aim of the paper is to popularize the importance of proper nutrition of preschool children due to their proper development. Since preschool children are in the process of continuous development, the paper describes basic nutritional needs and basic nutrients that each child should consume. In most cases, parents are not sufficiently informed about healthy food which they should provide to their children, and also they do not know about all the harmful ingredients in the food that children consume daily. Due to social and economic characteristics, parents often find themselves in financial problems and are not able to provide their child with the healthy food necessary for child's growth and development. Poor financial capabilities of parents can lead to health problems in children such as obesity, malnutrition, diabetes, and the like, if the child does not eat healthily. It is important to emphasize the importance of proper nutrition in kindergarten because a child spends most of its time there. In order to have proper nutrition in the kindergarten, HACCP system has been introduced to ensure the quality of nutrition in kindergartens. Physical activity of children needs to be stimulated on a daily basis and is equally important as proper nutrition. In this paper we have provided an example of preparation of activities with children on the subject of „Healthy food“ which indicates the use of various activities and approaches that are used while working with children in order to encourage them to research the healthy food further.
