Though I am typically social conservative, I actually agree with this movement. Don't get me wrong; I can see both the pros and cons of this issue.
Our country, thanks to the food industry and aggressive marketing, has doped up our society. Ever since we were young the got to us... through commercials. I'd rather see those two entities dealt a serious blow, but in addition I fully support this move. Why? People need to break their habits and take responsibility for their actions. From a traditionally Christian perspective, the body is a temple for God's Spirit, and must be kept healthy in practical terms. Habits such as overeating, especially when developed at a young age, are a real *bleep* to break.
I'm an example. Though I exercise vigorously, I eat a lot of unhealthy food. Yes, it's an overwhelming feeling that turns me into a munching zombie. Though, this zombies wants nachos, lasagna, and onion rings. ...and Chinese buffet... I love my mother and bless her masterful cooking... but she's like a huge spider. You think you're pulling yourself out of the web of temptation and then WHAM, homemade coffee crumble cheesecake.
Nip it in the bud. I support.
