Healthy living behavior in food must be implemented in society from an early age. School-age children are a critical age group because at that age a child is vulnerable to experiencing health problems that originate from unhealthy food. Apart from that, school-age children are also very sensitive to stimulation so they are easy to guide, direct and still have good habits, including healthy living habits.
