I chose the topic "Obesity of children in preschool age" because I am concerned about the growth of obese people in the world, especially children. The main causes of this disease, which we also call a global pandemic, are improper diet and insufficient physical activity. The aim of this paper is to make all parents and those who are about to become aware, and those who are in any way involved in the educational process of the child, aware of the importance of education about this disease that can occur in the womb. Introduce them to research that shows how many "chubby", sweet children, children are actually threatened and they are in danger of a number of health problems, if this problem is not taken seriously. Encouraged by this, I conducted the research myself in an educational group. The results only confirmed the fact that obesity occurs as early as preschool age.7 By being the mother of a one-year-old girl and looking at the problem from a parental perspective, I urge parents to educate themselves about the importance of a healthy diet, not to replace cooking in your own kitchen with fast food restaurants due to lack of time, to reduce sweets and salt. , and increases the proportion of water that is taken into the body, to increase physical activity and stay in the fresh air.
