I agree that the whole paleo diet is conceptual and we really don't have a lot of evidence to work with. I also agree that the Kitavans weren't low carb. They did eat whole foods which I believe in first and foremost when choosing a diet direction.
I guess my point is that the paleo diet isn't meant to reconstruct what happened in the past as we will probably never have to answer to that. But just as long as you are consuming whole foods and eliminating neolithic foods post agricultural revolution you will be doing yourself a lot of good. I think the paleo diet is evolving as new science comes out of the woodwork.
I also agree that there is good evidence against dairy especially when you are obtaining it from cows that could potentially be sick that are given hormones and antibiotics. But I believe that high quality raw butter and ghee are much less offensive than milk and cheese. And it is a hell of a lot better than cooking with vegetable/soybean oils which tend to cause so much more free radical damage when oxidized. My point in citing the French Paradox was just to illustrate that butter/ghee isn't all that bad for you even if it wasn't eaten in paleolithic times.
Aside from the Kitavans. I think the Massai Tribe in Africa are another hunter gatherer people that had a very traditional diet that is now a bit more westernized. Their diet traditionally was largely composed of saturated fat including milk but they have more recently been incorporating grains. They were also noted to have very low incidence of CVD and were very robust and athletic like the Kitavans.
I get the point of your thread. But I do think most diet directions can work depending on a whole lot of other factors just as long as you are eating whole fresh foods and reducing pro-inflammatory n6.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
