H is right. When i was doing too much flax meal it was screwing with my prostate(enlarged prostate). From what i recall flax seem to be having more estrogen effects than soy. I went on the soy craze as well and it did not give me issues as much as flax meal did. I dont see a problem with people doing fermented soy every now and then. Women probably benefit from soy+flax more than men. Lean meat works better for me than soy.
