I mulled it over once upon a time. Then I discovered that soy is supposedly bad for testosterone levels, and that most beans and nuts and cheeses were bad for folks with kidney disease. So I opted for 99% fat free turkey as my main protein source, and haven't looked back.
I've ate enough turkey over the last few years to start strutting and gobbling. Kidney function is holding steady, so I see no reason to change.
Soy is not a testosterone problem, but rather very high in estrogen. Women with estrogen-triggered breast cancers are told to never eat any form of soy. Others are warned to limit soy intake.
