Generally, junk food is ‘any food that is perceived to be unhealthy and of low nutritional value’ (Family Journal 2005, p. 3). Lin Tran (2005) also agrees with this, stating that consuming junk food such as chocolate bars, potato chips and sweets will raise the kilojoules intake and lead to obesity problem among children. Subsequently, demands that sale of junk food in school should be banned have been increased. Operators of school canteens, however, argue that the ban will erode their profitability as sale of junk food finances most of their income. A statistic released by School News (2005) shows that profit earned by Cook High School has decreased gradually after reducing the sale of junk food. Nonetheless, I strongly believe that sale of junk food in school should be banned because junk food brings health problems, changes children behaviors and leads to litter problem.
Firstly, the unhealthy consequences of consuming junk food are clearly noticed where childhood obesity problem is presenting an epidemic pattern in Australia. The fact that preferences of children toward junk food are increasing has been proven through a survey conducted by Australian Nutritional Journal (2004). The data shows that more than 50% of children consume food containing fat more than recommended intake. Paradoxically, less that 25% consume fruits and vegetables with recommended intake. By selling food that contain a lot sugar and fat, school canteens are obviously causing the increase in weight of youth (Reynolds 2005). Childhood obesity will lead to fatal diseases like heart diseases, osteoarthritis, and cancers in future. Besides, frequent consumption of soft drinks will decline the dental health of children.
Other than that, students’ behaviors tend to worsening due to over consume of junk food. Dr. Cray (2005) in The Food Showa claims that with the ease of availability of junk food in school, children cannot get the daily nutrients needed. This will retard their growth and development as well as their learning potential while triggering behavioral problems. There is no doubt that students’ eating habits on what they like to eat are determined at home. But sale of junk food in school canteens will add insult to injury where students will not be able to improve their habits. Once they can buy junk food easily from school canteens, they will be eating whenever they like without any consideration and it will affect their studies. Cancelling the unhealthy junk food from students’ diets can result in the improvement of their behaviors (Caputo 2005).
Another adverse effect of selling junk food in school is the litter problems generated. Junk food packaging which include cans, crisp packets, cartons and plastic containers will be thrown everywhere in the school by students. This indirectly contributes to the safety hazard of students (Family Journal 2005). It is absolutely true that increased litter problems will cause cleaning costs being pushed up while the image of school also being affected. If the sale of junk food in school is removed, school groundskeepers will be able to save time on cleaning the grounds while having additional time to do other maintenance projects (Green 2005). In short, banning the sale of junk food in school is beneficial as litter problems are solved.
To conclude, sale of junk food in school will bring bad effects to both students and school where it prompts health, behavior as well as litter problems. A sports nutritionist, Adrian Cook (2005) says that junk food can be nutritious if children eat them with moderation. Hence, parents have to cooperate with school authority in educating children to eat and drink moderately. After all, sale of junk food in school ought to be banned.
