Obesity as a chronic disease all over the world and in our country is increasing day by day. Obesity generally caused by the imbalance about consuming food , is seen as a result of modern life style that is lack of physical activity and unhealthy nutrition. It is related to many diseases such as cardiac diseases, type 2 diabetes and cancer. Nowadays obesity is expanding. Children live without movement just sitting all the time, watching TV and playing computer games. We have prepared our project to inform our students in secondary school about healthy and balanced nutrition and do works to ensure them to adapt it to their daily lives. We planned to do works to warn students about the danger of obesity and establish their awareness on how to eat healthy. We also planned to explain that it is very important to do exercise in addition to nutrition. We aim to describe the benefits of consuming vegetables and fruit and to explain harms of unhealthy food.
