All the books I read cite plenty of studies, including the one I mentioned, which is why I call it "one step above scientific studies", but you get called a whacko nonetheless if you or the author hold any opinions even moderately outside of the mainstream dialogue / mainstream medicine.
My original comment on this thread is at -1 even though what I said was factually correct (and I found all my linked sources above via exactly what I said, a quick Google search). Another of my comments on this post has the classic reply "ah but the author of your study has been accused of quackery if I google his name".
So I'd say a bit more open-mindedness would be in order.
