After Reading this article on the New York Times, in which a link between snack on public schools and food regulation apparently leads to healthier weight children, one might be tempted to think about a conspiracy theory. But that's just plain nonsense or, in the worst case, an appointment with a psycheatrist.
Gathering facts, evidence, and compelling data is vital in order to make a case, and eventually, beyond any reasonable doubt, revert the tendency to a healthier way of life. i do believe that it should be the consumer's choice, but at certain age, one can't really make a fully right decition, lacking the information needed to make a good, healthy decition.
Since Kids are still in the process of growing, their diet should be carefully attended and lureing them into buying candy and sweets it's just evil. Obesity rates in the states have been alarmingly incresaing since 1980 and this isn't a matter to be lightly considered.
The Article reminded me about these 2 films I'd like to recommend you.
