There is no such thing as healthy whole grains or good soy. Soy contains large quantities of natural toxins/antinutrients. Please see this article from the fabulous Dr. Joseph Mercola too.
Except soy in very, very limited quantities when it has been properly fermented such as with miso or natto. Emphasis on very rarely and only as a side dish. Some 2000 years ago the Chinese only ate fermented soy beans and never unfermented as we do today.
