Twelve Issues With Soy

3. Soy phytoestrogens are anti-thyroid agents that can cause hypothyroidism and could cause thyroid cancer.  Autoimmune thyroid disease has been linked to consumption of soy milk by infants.
4. Soy causes increased requirement for Vitamin B12.
5. Soy causes increased requirement for Vitamin D.
6. Free glutamic acid (monosodium glutamate or MSG) is a neurotoxin that is formed during soy processing and additional amounts are added to soy foods.
7. Soy foods contain high levels of aluminum which is toxic to the nervous system and kidneys.
8. Recent studies suggest a link between soy consumption and kidney stones.
9. Babies on soy infant formula have estradiol levels 13,000-22,000 times higher than babies on milk based formulas.
10. Buddhist monks ate tofu to reduce their libido.
11. Food manufacturers are using a gasoline additive known as hexane to process soy products.
12. Soy is the single most genetically modified crop (Contains GMOs) there is.
