Who hasn’t heard of the marvels of soy? The marketing bandwagon has touted soy as the perfect health food for decades. But could something that sounds so healthful actually be dangerous?
If you take the time to look into the actual science, then the answer is yes. Thousands of studies link soy to malnutrition, digestive distress, immune system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility—even cancer and heart disease.
One of the primary reasons it would be wise for you to avoid soy is that more than 90 percent of soybeans grown in the United States are genetically modified. Since the introduction of genetically engineered foods in 1996, we’ve had an upsurge in low birth weight babies, infertility, and other problems in the U.S., and animal studies have shown devastating effects from genetically engineered soy including allergies, sterility, birth defects, and offspring death rates up to five times higher than normal.
Soybean crops are also heavily sprayed with chemical herbicides, such glyphosate, which a French team of researchers have found to be carcinogenic.
Soybeans—even organically grown soybeans—naturally contain “antinutrients” such as saponins, soyatoxin, phytates, trypsin inhibitors, goitrogens and phytoestrogens. Traditional fermentation destroys these antinutrients, which allows your body to enjoy soy’s nutritional benefits. However, most Westerners do not consume fermented soy, but rather unfermented soy, mostly in the form of soymilk, tofu, TVP, and soy infant formula.
1. High Phytic Acid (Phytates): Reduces assimilation of calcium, magnesium, copper, iron and zinc. Phytic acid in soy is not neutralized by ordinary preparation methods such as soaking, sprouting and long, slow cooking, but only with long fermentation. High-phytate diets have caused growth problems in children.
2. Trypsin inhibitors: Interferes with protein digestion and may cause pancreatic disorders. In test animals, trypsin inhibitors in soy caused stunted growth.
3. Goitrogens: Potent agents that block your synthesis of thyroid hormones and can cause hypothyroidism and thyroid cancer. In infants, consumption of soy formula has been linked with autoimmune thyroid disease. Goitrogens interfere with iodine metabolism.
4. Phytoestrogens/Isoflavones: Plant compounds resembling human estrogen can block your normal estrogen and disrupt endocrine function, cause infertility, and increase your risk for breast cancer.
5. Hemagglutinin: A clot-promoting substance that causes your red blood cells to clump, making them unable to properly absorb and distribute oxygen to your tissues.
