Plus, the soy they consume, is more than likely, fermented.
IMHO, soy is bad stuff for young women who already produce enough of their own estrogen, for children who do not need to advance hormonally any faster, and especially for men, who darn sure do not need any feminization!
Who does that leave? MAYBE, big maybe here, post menopausal women : /

Correct. Western food products use mostly soybean oil, soy "milk" and tofu which are unfermented. Fermented soy products such as shoyu, miso, natto, tempeh are the staples of Japanese and Asian food.
Natto is particularly healthy specifically due to the fermentation process during which b.natto produces enzymes and amino acids.
