Soy the Poison Seed by: Dr. William Wong ND, PhD

This piece will be short and very much to the point.  As Americas largest cash crop, soy is being touted as having a myriad of health benefits.  Far from!  Soy is poison, period! All paid for opinion to the contrary.

What's bad about soy?:

• Contains Isoflavones (Genistein and Daidzein).  In soy the isoflavones are built in insecticides.  If they kill bugs are they good for humans?
• Isoflavones are estrogen like substances which have the same effect as the bodies estrogen.  Cancer  comes from having too much estrogen.  Irritability and mood swings, fat gain from the waist down, fibrocystic breast disease uterine fibromas  are all associated with estrogen dominance.  Instead of helping prevent the bad effects of environmental or natural estrogen dominance soy  isoflavones are now known to increase the bad effect of estradiol and estrone the two major bad guys of the estrogen family.  (1,2,3).
• Kills testicular tissue. In men it permanently reduces testicular function and lowers Luteinizing Hormone production. LH is what signals your testicles to work. This increases the probability of estrogen dominance in men with its hair loss, swollen and cancerous prostates. (4,5).   Male  children fed soy formulas and soy products may not ever get to like girls. Doris Rapp MD, the worlds leading pediatric allergist, asserts that environmental and food estrogens are responsible for the increase in male homosexuality and the worldwide reduction in male fertility. (6)
• Isoflavones decrease thyroid  hormone production. This can stunt children's growth and make the rest of us tired and fat. (7,8,9).
• Female children fed the estrogens in soy formula and products hit puberty very very early sometimes as young as age 6 to 8!  (10).
• Pregnant women eating soy products may affect the sexual differentiation of their children. Studies show malformations of the reproductive tract or offspring born with both male and female sexual organs. (11).
• Isoflavones decrease GOOD cholesterol (HDL). (12,13).
• Soy contains Phytin, which takes essential minerals such as iron, zinc, magnesium etc. out of the  body before they can be absorbed.  Also soy contains Trypsin inhibitors block this vital anti cancer enzyme, anti fibrosis enzyme. (14).
• A 7000 man 30 year  epidemiological study done in awaii shows soy is connected with a higher rate of Vascular Dementia (Alzheimer's disease).  (15,16).

Any opinions to contradict the facts noted above have been paid for by the Agribusiness giants Monsanto and Archer Daniels Midland.  Once public knowledge of their manipulation of public opinion and of the FDA becomes widely known, expect monster class action lawsuits against these folks.  They'll deserve it in spades!
