I think its more complicated. The American diet is contaminated with
agribusiness petrochemicals and much of the food is grown on land that
is dosed with Nitrogen, Phosphorus, & Potash. [that's a period] the
trace minerals needed for maximal mental development in childhood have
been leached out long ago. Its why the electorate got stupid enuf to put
in Republicans.

Poor Americans have used food stamps to buy junkfood and are grossly
obese, which dramatically reduces lifespan. Then too, the minorities in
particular dont have the genetic endowment to resist diabetes. Were we
to match white income levels in both Europe and America, the diff would
be a lot less. They are seeing the same health problems with Muslim
immigrants, who so far are not numerous enuf to affect demographics.

If you look at the iconography, going all the way back to the Mammoth
hunters and then the Neolithic farmers, obese goddesses are everywhere.
Native Europeans have evolved for 10,000 years with much higher rates of
obesity. But now, the toxins in the American diet are much devastating.
