  IAN: I doubt it. William Harris explored the question of
  aluminum's possible role in the findings of White et al:

  He had 16 soy products assayed for Al. Sure enough tofu
  was on the high side, at 15.99 parts per million. However,
  in the big picture that is not very remarkable. That's 
  16 micrograms of Al per gram of tofu. Estimates of daily 
  dietary Al intake range from 1.53 to 160 mg per person:

  So you'd have to eat about 2.2 lbs tofu/day to match the 
  high-end estimate of normal daily Al intake. Given that 
  White et al defined the high-end of tofu intake as two 
  or more servings per week, that would be below 2 lbs/day!
  And most likely "servings" among this Japanese American 
  cohort probably means meals wherein tofu is a component.

  That's not to say Al may not play a role in neurological 
  degeneration. I've posted a lot of evidence that it does:

  But given that there are many foods with as much or more 
  Al content than tofu as measured by Harris, and that 
  White et al tested ALL foods reported by the cohort and 
  only tofu produced a loud & clear statistically significant
  correlation to indicators of cognitive impairment and brain 
  atrophy, it stands to reason Al not producing that signal.
