Those illness that you are attributing to soy could be from unfermented soy as described in a blog that I found on line at:
Health Blogs
The title of the health blog is "
Is Consuming Soy Healthy of Risky?"
If soy is so unhealthy, then why is there very little incidences of these illness in various Asian cuisines that use soy products? In fact the Chinese, which uses a lot of tofu in their food, have extremely low incidences of cancer and other diseases.
