IAN: I'm also a tofu-eating vegetarian and
very concerned by that study!! However, I'm
inclined to believe it's accurate BECAUSE the
soy-phytochemical genistein has been shown to
fight cancer, and it has a property that many
anti-cancer drugs have, which is reducing the
rate of DNA synthesis. That property is great
for reducing the proliferation of cells and
promoting their death; unfortunately the
evidence cited suggests the cytotoxic
properties of genistein are nonspecific.
DNA synthesis is a critical attribute of the
life cycle of a cell. Here's some data on that:

http://www.geocities.com/CollegePark/Lab/1580/cycle.html
Again, research shows genistein reduces DNA synthesis.
There appear to be many health benefits of soybean
products, however, I believe that brain atrophy
is not an acceptable trade off unless genistein
treats an otherwise untreatable fatal illness.
Evidence also suggests that curcumin may kill
cancer cells. If true, I wonder how? It is
possible that our explorations into health
foods could run into unforeseen disasters.
A good strategy is probably to eat a wide
variety of foods, then if one should prove
harmful, you haven't been overexposed to it.
