Soy Lecithin.. to eat or not to eat

I've been doing some reading on soy lecithin. It seems to be the one soy product that really keeps popping up.  The evidence so far I'm reading hasn't helped me decided for or against.  It is a small derivative, and it basically makes it sound like unless you are taking in huge amounts as a supplement, it's probably not going to hurt you too much.  But, it's in almost everything, so it seems to me that unless you put forth some effort to avoid it, you would be taking it a large amount.  AND, it is from soy and the process it goes through can't be good.... so, I think it's just something I'll avoid when I can, but sometimes, let it slide... for now anyway...
