Aside from PUFA, the other big one is excess body iron stores. Iron intake is higher than it has been since 1909 (when they started measuring), plus, less is lost to activity (due to a more sedentary lifestyle), lack of intestinal worms, and bloodletting going out of style in the late 19th century. Pretty much every study that tests this hypothesis shows that iron reduction improves glucose tolerance and uptake into the cell.
I must be missing something: are you saying intestinal worms are a good thing to have?
