Stereotyping large food classes (highly processed, organic, fat-free, sugar-free) into healthful and non-healthful categories is no more accurate than doing so to people or any other complex system or organism.

For those who feel none of the highly processed foods are worth skipping:

-Normalcy: It's largely accepted that it is normal to eat things that come in foil packages. If you don't, you're likely uncool; a hipster, at the very least.
-Legitimacy: Father government has provided labels so we know exactly what is in the foil packages and what it is going to do to us.
-Complacency: It's just so much easier to accept that the friendly words on the comforting foil package are there to reassure one of the pure intentions of the makers.
-Ignorancy: No one is certain what is and isn't healthful in all contexts for all people. Epidemiology is more art than science and so far, none of the pictures are pretty. At one point, doctors endorsed certain cigarette brands. Heck, it seems like most people still think that all saturated fat is bad, low-fat dairy is more healthful than full-fat, and canola oil is a good idea.

One of the tenets of science seems to be that if we wait for a little, we're going to find that what we know now is wrong. If we can keep from locking our jaws onto each precious notion, we might do a little better at moving with greater fluidity in this sea of ideas.
