Junk food is the term that used to describe the food that is to be unhealthy and have low nutritional value. It is being blamed for the increase in childhood obesity (Smith 2005). Based on the statistics from the Health Foundation, (2005) it shows that most of the snack foods such as chips, soft drinks, hamburgers, instant noodles, confectionery and cookies are categorized under foods that have low nutritional values. So, I strongly believed that the sale of junk food in school canteens should be banned as it brings more disadvantages rather than the advantages itself. Some of the reasons to support the banned in selling the junk foods are as it is unhealthy food to be eat, causes major contributor to litter problems and also to help in improving the students behavior.
