USDA to ban "Junk Food"

I'm torn in the middle on this because we should have the freedom to do what we want. Yet there's no real downside to creating these restrictions, in fact grocery stores should do the same. However, diet is one aspect to a clearly healthy lifestyle, should we limit internet usage as well?

Are people overdoing it to the point that they get in a bad health situation that ends up costing everyone else?
I think food thing is one of those things that infringes on the rights of others and I'd be somewhat glad that government is taking care of them and therefore me. I think nearly "unlimited freedom" has its downsides and a "moderate" or similar approach is much more "healthy". But I'd understand why people there who have grown up with those values and ideals would oppose strongly to that ban or even feel torn on an issue that has no real downside (pragmatically at least... I guess).

[spoiler=]And anyway, if people there really dislike it and really think it infringes on their freedom they can go ahead and make the government change that. You guys are in a country with so much democracy that you want to spread it around the world after all[/spoiler]

I think that people and therefore government should think less in limitations and more on services to help people develop healthy life styles.
