Guest guest Posted August 9, 2004 Report Share Posted August 9, 2004 Mary Shoman is no lightweight. http://www.thyroid-info.com/articles/soydangers.htm Do Soy Foods Negatively Affect Your Thyroid? A Look at the Downsides of Soy by Mary Shomon It seems that there's isn't a newspaper, magazine or news program that hasn't recently featured a story on the amazing health benefits of soy food products and soy/isoflavone supplements. Soy is promoted as a healthy alternative to estrogen replacement for some women, as a possibly way to reduce the risk of breast cancer, as a way to minimize menopause symptoms, and as a healthier, low-fat protein alternative for meats and poultry. But what all the positive stories fail to mention is that there is a very real -- but very overlooked -- downside to the heavy or long-term use of soy products. Soy products increase the risk of thyroid disease. And this danger is particularly great for infants on soy formula.

It's promoted as the miracle food that will feed the world while at the same time prevent and cure all manner of diseases. But what if all you've read about soy is nothing but a multi-million dollar marketing strategy based on scanty facts, half-truths and lies? [snip] Weston A. Price Foundation http://www.westonaprice.org/soy/index.html Confused About Soy? High levels of phytic acid in soy reduce 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. High phytate diets have caused growth problems in children. Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders. In test animals soy containing trypsin inhibitors caused stunted growth. Soy phytoestrogens disrupt endocrine function and have the potential to cause infertility and to promote breast cancer in adult women. Soy phytoestrogens are potent antithyroid agents that cause hypothyroidism and may cause thyroid cancer. In infants, consumption of soy formula has been linked to autoimmune thyroid disease. Vitamin B12 analogs in soy are not absorbed and actually increase the body's requirement for B12. Soy foods increase the body's requirement for vitamin D. Fragile proteins are denatured during high temperature processing to make soy protein isolate and textured vegetable protein. Processing of soy protein results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines. Free glutamic acid or MSG, a potent neurotoxin, is formed during soy food processing and additional amounts are added to many soy foods. Soy foods contain high levels of aluminum which is toxic to the nervous system and the kidneys. Quote Link to comment Share on other sites More sharing options...
