Proper nutrition has always been important for health, and over time more and more importance is given to a diverse and varied diet. Children of younger school age should most of all have properly arranged meals with regard to their activity and time spending during the day at school where they also consume some of the meals. The diversity and variety of their meals means that their diet should consist of foods from all categories arranged into five meals throughout the day. A very important role in the formation of healthy eating habits of children of younger school age is played by their parents, who by their example are the greatest role models to their children. An important role is also played by teachers, with whom children spend time every day, and teachers are the ones who, with their knowledge and effort, can pass on and create future healthy eating habits for children. For the purpose of this paper, a survey of 3rd and 4th grade primary school students was conducted in which the eating habits of younger school age students were researched. Children should most of all avoid consuming large amounts of sweets and snacks, avoid sugary drinks and replace them with water, and also increase the intake of fruits and vegetables. In conclusion, the research showed that students have relatively good eating habits that are in line with the National Guidelines for the Nutrition of Elementary School Students, and most of them engage in some sort of sports activity in their free time.
