Food labeling has the potential to help people eat better, if they learn to become savvy consumers and educated about their health. Labeling genetically modified foods would be of huge help. What people have to realize,though, is that even labels can be misleading. Currently in the US, a product labeled "all natural" can still contain pesticides, genetically modified material, or even naturally derived materials that can still be harmful. Labeling is a good start, but we need people to be more proactive in their own health as well.
I do believe if their were educational labels on how to lose weight or help with dieting it would definitely help with the population eating in a better way because it would remind them what can happen if they continue to eat unhealthy and what could happen to their body
A tax directed at graduates to pay for higher education facilities would be similar to a tax targeting smokers or people who consume gas. Yes, the services were used by the graduate, as in the other cases, but the benefit is not just to the graduate. Taxing an item that they have already paid for through tuition would discourage people from seeking higher education, thus reducing the number of doctors, teachers, accountants, etc.
Health warnings or advice, on food products, will not encourage to people to change there diet if they don't want to. People would ignore the label and continue to do what they want to. Cigarette packs have had a warning from the surgeon general, to encourage people to not smoke, for years That warning has hardly been effective. The simple fact is, people will change when they are ready.
I do not believe labels on food that encourage people to eat better would actually make them eat better. I believe these labels wouldn't add much value as the ingredients and nutrition information provide far more information to consumers. The proposed plan sounds like some kind of gimmick, which I doubt would work.
