The reality is that you have "intellectuals" as well as "collective wisdom" on both sides of the debate</blockquote>
No, you don't. That's exactly what you don't have.
Collective wisdom is not a "side". You don't even understand what I'm talking about if you think "collective wisdom" is a side. It means accumulated knowledge spread throughout a society. Collective wisdom was what you had in traditional societies before intellectuals started coming up with ill-informed and partial pictures.
It's irrelevant to me whether you regard me as "misguided" or not. That traditional societies - even those living in supremely hostile environments (for example, Australian Aborigines: http://www.westonaprice.org/traditio...borigines.html ) - had managed to find and prepare appropriately nutritious foods when not bullied by intellectuals is a fact.
