I had to dig this post up from 2.5 years ago - there's eerily some truth to it.
Re: eggs =/= dairy - I don't think that you can be too harsh on people. The food pyramid (great bastion of the SAD diet and taught in most, if not all, North American public schools) has eggs in the dairy quadrant (or band of the "rainbow" in the new scheme), along with milk, cheese, butter, yogurt, etc. Not sure why. Would make more sense in the "meats & alternatives" where they have the fish, tofu, beans and legumes.
Fascinating reading on the "marketing" of the food pyramid (and myriad other subjects) is in Michael Pollan's "In Defense of Food: An Eater's Manifesto." He certainly points out how little "real food" there is in grocery and supermarkets these days.
