Soy Lecithin - good or bad?

O.k. - it's been made clear by some nutrition experts that subtances that utilize all or parts of the soybean can have negative health consequences. But where I'm confused is whether this includes soy lecithin. The anti-soy people seem to at least passively include soy lecithin in their "all soy is bad" zeal - as they don't bother to distinguish soy lecithin from other soy products, nor do they cite any benefits of lecithin. And I've seen accusations that soy lecithin is just a waste product of the soy industry that "Big Soy" (and nutritional supplement companies) manage to cleverly market as "healthful".

Recently, I took 1 tablespoon of soy lecithin daily, and had planed to resume my supplementation. I took it for the large amounts of phosphatidyl choline and phosphatidyl serine it contains - for these substances allegedly are good for protecting the nervous system, for brain function (I've read that the brain is 30% lecithin), and for liver function (among other things, it can allegedly dissolve gallstones). But I don't want to take it if I'm doing signficant collateral damage, or if I'm actually doing more harm than good. For one thing, I seem to be suffering from symptoms of "estrogen dominance" - and a soy product can potentially exacerbate this condition - greatly.

Here are some chilling headlines about soy - but the question is - does this include soy lecithin?

Also, so many prepared food products in the grocery store aisles have soybean oil as an ingredient. Does this mean that every time I buy one of these products - I'm doing damage to my body?
