My brother, who is Doctor, has said to me many many times that using tofu is bad for males. Is true?

My brother, who is my Doctor, as well (wholistic surgeon/herbalismist) say that for a man to use tofu in food too much is bad. He says tofu contain Estrogents and if too much Estrogents are in a man he may become effeminate. Is this true?My brother, who is Doctor, has said to me many many times that using tofu is bad for males. Is true?
There is still a lot of controversy with this. I've heard this many times about soy products (soy milk, tofu, etc...) I would just stay away from it. The estrogen found in soy products mimics womens hormones.





Personally, I stay away from it.
