Re: Soy Neurotoxicity?

So tofu from soybeans is bad, but Phosphatidylserine from soybeans
might be good? Seems premature to start avoiding all soy products.

The more suspect elements in the Soy bean are usually thought to be the
phytoestrogens: Daidzein, Genistein, Glycitein, Formononetin, etc.

Purified extracts of soy phospholipid cocktails should not contain those.

Many thanks for the clarification.

Does this mean you might continue to have concern about food-grade soy
protein powders, soy lecithin, etc.? What about soybean oil? The
consumer really has no way to evaluate the care with which such
products are produced.

(Note that breast cancer patients are also advised to avoid soy
products, presumably to avoid plant estrogens which might stimulate
growth of hormone-responsive cancer cells.)

I suppose it might be helpful to talk to a "food technologist" who
knows in detail how commercial food products are processed.

Personally I eat very few bean-based products. When I do eat them,
it tends to be peas, lentils, and fava beans - in moderation - and
I tend to prefer eating bean greenery to eating the beans themselves.

I don't eat any protein powders, and I don't eat egg or soy-derived
lecithin - so I have not looked into these much.

AFAICS, soybean oil won't have much in the way of phytoestrogens in
it.

It is a popular cooking oil - but I don't do cooking with oil.

I'm not immediately attracted by the idea of eating bean oils;
though as fats I don't see a great deal wrong with them.

Soy oil does contain phytosterols. I would want to learn more about
their properties before consuming much soy oil.

Perhaps erring on the side of caution:

``In spite of initial optimism, it is not clear whether eating
foods rich in phytoestrogens decreases breast cancer risk. This is
an active area of research with much work needed to resolve
this issue.

``Whether soy can help protect against breast cancer in
post-menopausal women is unclear at this time.''

Tim, thanks again for your prompt response. Much to think about here.
