Eating habits and kinesiological activity ensure proper growth and development while reduce the risk of developing certain diseases. By combining food of plant and animal origin in the diet, the body is supplied with all the nutrients it needs. These include: carbohydrates, fats, proteins, vitamins and minerals, dietary fiber and water. The importance of developing healthy living habits in preschool children is evident throughout their life. The principles of healthy living include the application of the pyramid of healthy eating, but also the pyramid of active onset. Based on a variety of studies and learning theories, the environmental importance of developing healthy habits can be seen. On the one hand, the child's environment is made up of family and friends, while on the other, it is an educational institution. In addition to diet, regular physical activity is of great importance. From an early age, the primary purpose of physical activity is to develop motor and musculoskeletal systems. Further regular physical activity develops the child's personality, stimulates socio-emotional development, promotes the work of the respiratory and cardiovascular systems. Today's trends show a tendency of reduce movement in children due to increased use of technology and dominant motor vehicle transportation. Kinesiological activities are divided into monostructural (swimming), polystructural (tennis), complex (football) and aesthetic (gymnastics). As part of the final paper, a study was conducted with the aim of discovering dietary habits and the amount of physical activity in preschool children. For the purposes of the survey, a short questionnaire was used in which twenty respondents aged five to six and a half years participated. The results indicate a lack of movement in their leisure time and a lack of obedience to the principle of healthy eating at home.
