The graph I used, which I can no longer get to since the page has
apparently been deleted, showed lactose intolerance to be lowest in the
U.S., Northern Europe, and Australia (something like 10-20% of the
population), and highest in China and among Native Americans (90%+). In
fact, in a few really isolated areas, it was near 100%.

My point was that if pasteurization is truly the demon he said it is, and
is truly a "cause" of lactose intolerance, then wouldn't the countries who
use the most pasteurized products have the highest incident of lactose
intolerance? Is my logic faulty in some respect?
