I agree 100% although I still do tend to use the grok thing in conjunction with that actual evidence. Speculating about grok should only be useful for forming a hypothesis which needs to be proven with empirical evidence and reasoned arguments for the reasons you stated. It's just that most of the time what is paleo is what is healthy. Although it doesn't follow that what is healthy is always paleo. No dogma here. That's why I like Mark's approach.
