Now that is amazing.  Pity that Diamond doesn't hazard
a guess as to what the selective factor could be - he
just refers to it 'eliminating thrift-gene carriers'. 
I do wonder, though, about some of the 'lifestyle'
factors, for instance Diamond says that British and
German emigrants to the USA have 8% incidence as
opposed to 2% in Europe, under 'similar lifestyles' -
but my own subjective impression is that American and
European eating habits are quite different.
