"The idea that you are what you eat has been enthusiastically promoted
for years by Den Fujita, the eccentric billionaire who brought
McDonald's to Japan three decades ago. 'If we eat McDonald's
hamburgers and potatoes for a thousand years,' Fujita once promised
his countrymen, 'we will become taller, our skin will become white,
and our hair will be blonde.'"

Part of the reason japan had such a high life exptectancy rate was a
healthier diet than americans.  This however shows that japs would
cowardly shorten the lives of their own countrymen just to copy white
americans.  I hope this answers your questions.
