It's what Michael Pollen critiques as nutritientism (although Pollen also believes that anti-grain, anti-dairy types are wacky as well).
It's been a while since I read In Defense of Food but I think the major points were:
1. Eat food mostly veggies
2. If your grandmother doesn't recognize something as food it probably isn't
3. If you can't get something from the ingredients into what it is your about to eat in less than 6(?) steps then maybe you shouldn't eat it.
In my mind at least those are Paleo-ish guidelines which are around what I try to stay with (though not always successfully).
