Jessica Leung, 16, Our Lady of the Rosary College Warning labels on food are useless. Imagine a can of cola bearing a warning label that 'It makes you fat and is bad for health'. Many people will simply ignore the label and drink the beverage anyway. Having warning labels on food would have the same effect that warning labels on cigarette packages have now: not much. Many people still smoke. Warning labels on food would not change the eating habits of most people. Many people already know that fast food is not good for them. Yet companies like McDonald's are doing roaring business. Junk food is both convenient and delicious. How would warning labels on hamburgers and French fries improve matters? In addition, implementing such a policy would be difficult and controversial. Companies like McDonald's would likely object to their food being labelled. They could also find ways to get around such labelling. And how about fried foods sold on the street, for instance? Should they, too, be labelled? If so, what agency could ensure that vendors adhered by regulations? Besides, classifying food items into healthy and unhealthy categories would not be a clear-cut business. Many food items do not pose health problems if they are consumed in moderation. In other words, warning labels would be not only ineffective but also unjust in some cases. What the government needs to do is educate people about healthy diets so they can develop healthier eating habits. Cathy Chan, 16, CCC Kei Chi Secondary School More and more people are becoming aware of health-related issues. Nonetheless, problems of obesity and diabetes are worsening in many countries because of people's unhealthy diets. Food labelling is a good way to help people stay healthier. Comprehensive food labels can help people make better decisions about what food they should buy. Current food labels provide eight pieces of nutritional information: calorie, protein, total fat, saturated fat, trans fat, carbohydrate, sugar and sodium contents. Such data help us make more informed choices. It is true that many people simply ignore food labels and choose unhealthy food items, like fast foods and sugary drinks. All in all, however, I do think the labels serve their purpose well by alerting people to the contents of the food they consume. That way they are more likely to develop a habit of selecting healthier items. Placing warning labels on unhealthy food items would help further educate people about the importance of dietary habits. That is essential for making sure that they can adopt a healthier lifestyle by eating well. I am firmly on the side of the argument that food labels serve a vital purpose. The government should launch an educational campaign about food labels. It should also place warning labels on seriously unhealthy food to warn people of the dangers involved in consuming them.
