I think the idea of a government dictating what you get to eat is still insane. How long till some politician gets paid off to pass some specific food? Such power should always be setup under the assumption that a bad actor will eventually corrupt it.

And then of course you get the blind thinking "the government put it on the healthy list, so it must be healthy"...

The better solution (in my opinion) is to educate people - to the point where they choose to make the right choices. Diet and exercise is just as important as Math and English when teaching kids to be productive members of the work force. This will massively pay off in the long run, as such habits usually get passed down for generations.
