Re: Tofu (soy) and estrogen?
Yes, soy does have estrogenic properities but is more of a concern for females, if they have had hormone positive breast cancer. I believe it would have very little effect on a male's hormone balance. Keep in mind that soy also has a chemical called genisten, which many studies suggest is a cancer fighter. Soy is also good for the bones and easier on the kidneys, than animal protein. Overall, I believe that soy is a very healthy addition to most people's diet and poses very little risk for the average person.
I follow a plant based diet as well and am also a breast cancer survivor.
Even in br. cancer, oncologist's have different views on soy. Most say no or use in moderation but avoid soy pro powders, as they have very high levels of soy protein.
Hope this helps.
