I would say soy since it has more health benefits.
One reason is that I generally don't have a lot of time to spare. And I don't want people waiting around for answers. There are times where I have not gotten around to writing people back for months after they have sent me questions because of time constraints. Right now I have some spare time so I am hanging out for a bit. When I get busy again you won't be seeing much of me. I also like picking and choosing what I respond to. All to often I see people self diagnosing themselves wrongly, but people do not want their belief systems challenged. So it would be a waste of my time to try and convince someone of what to do when they already think that they know what is wrong with them. So overall my random posting works best for me, and is what I prefer.
