I don't think it would be a god idea to ban fast foods. Don't get me wrong I am a pro health person but, I read an article once that says that there is no such thing as junk foods. Food that is bad for your health are basically due to overconsumption of it(e.g. sugar, oil, etc.). It might be better that instead of banning these type of foods. Healthy foods should be priced way lower. This would encourage a lot of consumers to opt for healthy food instead.
