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.
