If saturated fat were bad then I would be dead! The very fact that I am talking to you should make you worry...

Saturated fat is not bad or unhealthy! I doubt if you find any recent study that would prove it unequivocally in a clear-cut trial! Try it. If Pritikin said so, that did not automatically make it true. Even if he won a marathon.
Not even sugar must necessarily be always bad. In some
cases sugar in low caloric settings may be better than starch (for rodents)!
Yes the saturated fat study is not very accurate but it does demonstrate the utter lack of any negative trend! In spite of what all the low fat vegan promoters have been claiming for years.
You are making too many assumptions such as in
" if they eat less saturated fat, they usually are eating more white flour." As if they were automatically true. Even if your assumption were correct it would only led us to believe that saturated fat is supposed to be as bad as white flour. Since all the studies that I have seen comparing white and whole wheat food showed only a small marginal difference, you would run up against a politically incorrect notion of whole wheat being only slightly "less bad" than the white!
Also you have absolutely no grounds to imply that a more accurate data would have somehow vindicated Pritikin's anti-fat bias. It might in fact bury him even deeper...
