The Dark Side Of Soy
From Kurt Boyer

(Note - We have long been opposed to soy products for a number of reasons, most of which are detailed in these links below. We recommend Rice Dream which comes in three flavors and is made with an excellent water source which contains no fluoride among other good attributes. -ed)
Hi Jeff
I noticed your link to an article on soy products (Milk Without the Moo A Soy Product Gets A Major Makeover), and thought I would send this along to balance the picture. I was certainly a believer in soy until I started learning a bit...
".......But two of the FDA,s experts on soy - Doerge and his colleague, Daniel Sheehan - have stepped forward to criticize their own agency's claim and even attempted in vain to stop the recommendation...."

"We are doing a large uncontrolled and unmonitored experiment on human infants." --Dr. Daniel Sheehan, research scientist for the FDA and expert on soy

Scientists Protest Soy Approval In Unusual Letter,
FDA Experts Lay Out Concerns
Researchers Daniel Doerge and Daniel Sheehan, two of the Food and Drug Administration,s experts on soy, signed a letter of protest, which points to studies that show a link between soy and health problems in certain animals. The two say they tried in vain to stop the FDA approval of soy because it could be misinterpreted as a broader general endorsement beyond benefits for the heart.
The text of the letter follows.
DEPARTMENT OF HEALTH and HUMAN SERVICES Public Health Service, Food and Drug Administration National Center For Toxicological Research Jefferson, Ark. 72079-9502 Daniel M. Sheehan, Ph.D. Director, Estrogen Base Program Division of Genetic and Reproductive Toxicology and Daniel R. Doerge, Ph.D. Division of Biochemical Toxicology February 18, 1999 Dockets Management Branch (HFA-305) Food and Drug Administration Rockville, MD 20852 To whom it may concern,
We are writing in reference to Docket # 98P-0683; "Food Labeling: Health Claims; Soy Protein and Coronary Heart Disease." We oppose this health claim because there is abundant evidence that some of the isoflavones found in soy, including genistein and equol, a metabolize of daidzen, demonstrate toxicity in estrogen sensitive tissues and in the thyroid. This is true for a number of species, including humans. Additionally, the adverse effects in humans occur in several tissues and, apparently, by several distinct mechanisms..."

The Dark Side of Soy - Supplements May Do More Harm Than Good

Soy Story - The Politics Behind the Boneless Protein
By Britt Bailey
...... "While soy production is growing, so is talk of its purported benefits. Everywhere you turn it seems the media is touting soybeans and their derivatives. The powers that be, namely Monsanto, DuPont, Cargill, Archer Daniels Midland are betting their future on soy.
Back in the wings, a growing number of scientists are quietly expressing concerns over soy's hidden risks. It is, after all, a plant-borne hormone. And as history has shown , adding hormones to the body is fraught with danger"....
A Hawaii research team says high consumption of the soy product by a group of men lowered mental abilities
So just what are these goitrogenic agents? In 1997 research from the FDA's National Center for Toxicological Research (NCTR) showed that the darling of the soy industry, the isoflavone genistein, was a potent inhibitor of Thyroid Peroxidase (TPO); in fact genistein is a more powerful inhibitor of TPO than common anti-thyroid drugs! If genistein could inhibit TPO in vitro, it follows that it could result in an elevation of Thyroid Stimulating Hormone (TSH), and a subsequent decrease in thyroxine (T3) in vitro; in other words consumption of the soy isoflavone genistein might result in hypothyroidism and goitre.
Recent research leaves little doubt that dietary isoflavones in soy have a profound effect on thyroid function in humans. A study by Japanese researchers concluded that intake of soy by healthy adults for a long duration caused enlargement of the thyroid and suppressed thyroid function....
