Having an education in the life sciences will help as will lots of training outside the classroom. But research is so specialized today that it becomes more and more challenging to separate the legitimate from those looking for a desired outcome. This one isn't that tough, however.

It’s just that I saw it first-hand with my relative, manboobs and all. Every symptom claimed in the article and the video at the link, he had. And he died too young, after living in misery on a heavily soy vegan diet. So there’s that. And having seen it and mourned it, you’re not going to convince me otherwise, so stop trying.
