The answer is "no" because they didn't exist, so it was rhetorical. The point I'm trying to make is you can't compare a culture whose PUFA came from nuts, seeds and animals to a culture whose PUFA comes from rancid, refined vegetable fats. The argument seems to be two-fold:

I call BS on BOTH of those things. My argument:
The PUFA in the American diet is largely chemically-extracted polyunsaturated oil that's been severely damaged in the process. Furthermore, it is stripped of the antioxidants of the whole food that protects it against oxidation upon consumption. You're comparing trans-fat ridden PUFA to whole nuts, seeds and animals high in PUFA.
Furthermore, omega 3 is even more prone to oxidation than omega 6. If we ate the same oils extracted the same way but it was omega 3 in an 8:1 ratio to omega 6, we'd be in even worse shape because they would have even higher levels of trans fats.
All this study shows is that trans fats are harmful, as THAT is what's high in the SAD. This study does not show PUFA in a positive light, it shows trans fats in a negative light! I am willing to bet that if Culture A did not have such high levels of PUFA it would have been even healthier. Whole nuts, seeds and PUFA from animals clearly are not as big of an issue as high-PUFA hexane-extracted rancid oils loaded with trans fats, but that doesn't mean nuts, seeds and PUFA from animals are healthy. It's just not nearly as bad, which gets a big fat DUH! from me. I still subscribe to beef, lamb, coconut and dairy as the ideal sources of fats.
Oh yea, and chocolate. Seriously.
Omega 3:6 ratio is a confounding factor. It's the trans-fats in the omega 6! Adding omega 3 to balance it out only adds more trans fats!!! REDUCE OMEGA 3 AND OMEGA 6 for best health. That's my advice.
