I remember a study (2000?) done at the University of Hawaii by Dr. White
regarding an association between the consumption of tofu in mid life and
dementia in old age. Later I heard a rumor that this was caused by the
metal containers the tofu was fermented in, but I have never been able
to follow it up. Is there any site or source that addresses this? Do
you know of any brand of tofu that is not fermented in metal pans?
