Junk Food...should it be illegal?

This awesome article certainly makes the case against junk food but then again what do they know? What's a few servings of fries and soda's going to do to us? God forbid they take my trips to Harvey's away!! Or is it time to heed the call that articles like this one calls for? How would you establish a case for and/or against junk food? How is this issue on that is truly global in scope? Give me your thoughts!!!!
