To see the other side of the coin and develop a better side of our own, what logical & substantiated arguments can you make against the Paleo diet as you define it? Saying "there is no counter-argument" is, I feel, an intellectually cheap way out. I feel by sounding out how well we know certain parts of Paleo by, for example, noting internal inconsistencies, we can make Paleo more scientific- that is able to generate falsifiable hypotheses. By doing this we'll help ourselves & future generations understand our physiology better, perhaps giving us all better lives. Without a coherent Paleo theory, it's hard to make a case to any funding agency to research this stuff, which leaves scientists marinated in SAD conducting, publishing, reviewing, and editing most research in this area.
Eager to hear your thoughts, Mike
