Grocery store vs school cafeteria
It's important to make the distinction between the adult marketplace like grocery stores and children's marketplace like school cafeterias. The movie talks about both places and I wasn't entire comfortable with their seeming to apply the same standards to both places.
For school, ideally in the future, there should be a process or machine that measures every individual's health condition and based on that allow/disallow or strongly suggest what foods are available for them to eat.
As for grocery stores, as someone with a high metabolism and finds it difficult to keep weight on, I don't want companies to remove all the options for full calorie / full flavor versions of their products. I enjoy eating tasty food and I have the kind of body that can accept more of it than some obese child.
I sympathize with those who have problems with restraint or lack discipline, but don't take it out on people who don't have that problem. And it's incorrect to assume everyone is incapable of enjoying things in moderation, that we're all children and need the marketplace dumbed down for us.
