Beware unfermented soy foods

I've been sitting on this story for too long. I keep wanting to write long, but don't have the time. So I figure I will settle simply for providing links with brief commentary that, I hope, will pique your interest.
I saw this article by Dr. Joseph Mercola about the dangers of unfermented soy. It has been linked to brain damage, breast cancer, and more.
And what are unfermented soy products? How about . . . soy milk, soybean oil, soy protein (an additive in many foods; look also [primarily?] for "textured vegetable protein" or TVP), soy "cheese," soy "ice cream" and soy "yogurt," tofu, edamame . . . --You know, all those supposedly "healthful" foods.
All those "healthful" foods that aren't--for various reasons, including these . . . that Mercola lists and documents in his article:
  • 91 percent of soy grown in the US is genetically modified (GM). For many of us, that poses no worries. After all, the U.S. government wouldn't permit the widespread introduction of harmful GM organisms into our food supply would it? (More on that in future posts.) More important: The primary reason for the GM is to make the soy resistant to the herbicide Roundup--which we will get to in the next point.
  • You may be sure that all the GM soy is "loaded with the toxic pesticide" Roundup.
  • Soy contains natural toxins known as "anti-nutrients" which "interfere with the enzymes you need to digest protein."
  • Soy contains hemagglutinin, "a clot-promoting substance that causes your red blood cells to clump together."
  • Soy contains goitrogens, substances that "block the synthesis of thyroid hormones and interfere with iodine metabolism, thereby interfering with your thyroid function."
  • Soy contains phytates which "bind to metal ions, preventing the absorption of certain minerals, including calcium, magnesium, iron, and zinc -- all of which are co-factors for optimal biochemistry in your body."
  • Soy is loaded with the isoflavones genistein and daidzein which "mimic and sometimes block the hormone estrogen, and have been found to have adverse effects on various human tissues. Soy phytoestrogens are known to disrupt endocrine function, may cause infertility, and may promote breast cancer in women."
  • Soy has toxic levels of aluminum and manganese. --For example, "[s]oy formula has up to 80 times higher manganese than is found in human breast milk."
  • Soy infant formula puts your baby’s health at risk. --Among the startling and disturbing statistics Mercola references:
    • "[E]strogens in soy can irreversibly harm your baby’s sexual development and reproductive health. Infants fed soy formula take in an estimated five birth control pills’ worth of estrogen every day."
    • Infants fed soy formula have up to 20,000 times the amount of estrogen in circulation as those fed other formulas!
Mercola provides links for all of these claims. You'll have to read the original article for details.

One key item. Please pay attention to the point about unfermented soy products. Fermented products (which, Mercola notes, are healthy--for reasons he explains) include . . .
  • Tempeh
  • Miso
  • Natto

  • Soy sauce. ("Be wary," however, Mercola notes, "because many varieties on the market today are made artificially using a chemical process.")
