nutritious junk

Its time for the weekly food for thought, and today i am posing a rather controversial issue that's been circulating lately.  Apparently, most of the nation’s school districts now offer lunch plans that let parents pay up front for the school cafeteria. Among them are online plans that help students manage their lunch money while letting parents track the foods their kids are eating.  So basically, parents can see what their kids are buying and many plans let parents have control over what their kids can and cannot buy.  Is this ok? I mean sure, we love our parents and they always want the best for us, but i think as kids grow older, they also need practice in making their own decisions.  Parents already have control over dinner and breakfast, so is it right for they to keep their kids on a short leash in school as well?  I am torn over this one. I went to private school that didnt even have a cafeteria, we just had lots of vending machines and a big catering truck.  I would be a little upset if i was banned from buying a cookie though.  But could this maybe help diminish childhood obesity, or is this just plain nosy? let me know what you think.
