There are caveats on the use of soy for those with thyroid concerns, as well

as some nutritional concerns. The key to their use is in using them as the

Asians used/use them, fermented and/or fortified with sea minerals.

" The antinutrients in soy are:

1) Phytates, which chelate (latch on to) minerals, particularly zinc. Zinc

is needed for proper growth and reproduction function. Publications exist

indicating that third world countries that heavily consume phylates have

physical stunting.

2) Protease inhibitors that prevent proper digestion of food by pancreatic

enzymes.

3) Genistein, which inhibits angiogenesis and glucose uptake. This is great

for inhibiting the vascularization and growth of tumors because they need to

be vascularized and burn glucose to thrive. Too much of it would not be

good for normal processes that require vascularization (eyes, hair follicle)

and glucose utilization (brain). Genistein also inhibits tyrosine kinases,

enzymes that are over expressed in tumor cells but are also needed for

normal function of many normal tissues, particularly the hippocampus

(important for memory consolidation) in the brain. The amount of genistein

derived from a typical Asian soy-rich diet is probably not enough to create

a problem. The amount of genistein in some of the Western products is of

concern, but may be perfectly safe. The amount of genistein in some

processed soyfoods is unprecedented in human evolution-time will tell us

what it's doing to our brains. Genistein also inhibits aromatase, which

converts androgens to estrogens. Natural estrogens are needed for proper

brain function, which is why Alzheimer's patients do better on estrogens-it

reconnects the circuits. We don't know what impact genistein has on these

same pathways-will it have the same benefits as natural estrogens, or will

it aggravate estrogen deficiency symptoms in the brain over the long term.

Time will tell. I am concerned that women believe genistein will replace

natural esrogens, and this may not be so.

4) Goitrogenic factors: Complex molecules in soy that block the uptake of

iodine, resulting in thyroid deficiency. The Asians eat most of their soy

with mineral rich sea vegetables containing plenty of iodine and zinc. We

don't.

The process of fermentation removes most of the antinutrients of soybeans,

making it a nutritious food source. The Asians eat most of their soyfoods

in fermented form. We don't. The Asians prepare soy milk, which is not

fermented, fresh each day (more than a day or two old and it's considered

stale) and fortify it with appropriate sea minerals to conterbalance the

antinutrient effects of phytates, etc. We don't.

At the end of this big human experiment I think we will come full circle and

realize we forgot to read the directions given to us by thousands of years

of experience by Asians. "

Heck, so that's why we Asians are short :-)
