Unfortunately the news about soy products isn't all good either. An egg is not necessarily an egg. What I mean by this is simple.
Eggs are very unhealthy to eat.
There are eggs, and then there are eggs. Eggs from the first kind of chicken are very healthy to eat, and from the second, are very unhealthy to eat. It may be a similar situation with your info about the soybeans, but I do not know this for sure. I have heard similar conflicting statements though, and suspect that tis may be the case. Most likely, it is a difference between hybridized and non-hybridized soybeans.
