Soy products contain glutamates which are excitotoxins to the glutamate receptors in the nervous system, GI tract, endocrine system and heart. If you have a medical condition (known or as of yet unknown) glutamates can unleash a hyperexcited state. "The worst of the things they're doing are the soy extracts. Soybeans, naturally, have one of the highest glutamate levels of any of the plant products. When you hydrolyze it, you release the glutamate, and the soy protein isolates. The glutamate levels are higher than a lot of what you'll find in MSG products, yet the vegetarians are just eating it like it's the healthiest thing in the world. There was a 25-year study done, which looked at people who consumed the most soy products, and they followed them for 25 years and did serial CT scans. They found out that the people who consumed the most soybean products had the greatest incidence of dementia and brain atrophy."

If you have migraines or other medical conditions, you might want to eliminate soy and the other products mentioned. “As of 2004, 85 percent of the U.S. soy crop was genetically modified, accounting for some 63.6 million acres of soybeans. Statistics for 2003 indicate that at least 55 percent of soy worldwide is now genetically modified.” http://gentleworld.org/as-we-soy-so-shall-we-reap/ "Women have been encouraged to use high genistein soy products to alleviate symptoms of menopause and as a guard against bone loss and breast cancer. But given the full range of effects of genistein in the body, high consumption could result in age-related memory loss. Commercial soybean products offer genistein levels as high as 20 to 60 mg per serving. Asians are presented as an example of the benefits of eating soybean products because their incidence of breast cancer and osteoporosis is low. However, the Asian diet of fermented soybean products such as miso and tempeh includes only around 5 mg of genistein a day. Genistein slows the growth of blood vessels to tumors, another action that makes it popular as a cancer fighter. However, it has the same effect on blood vessels serving normal cells. Eating a regular diet high in genistein could result in the starvation of healthy blood vessels, resulting in a reduced supply of oxygen to cells, setting up a cancer promoting situation. In a graphic example of how genistein slows cellular energy, a study found that eating high levels of it slowed hair growth by 60 to 80 percent" Learn more: http://www.naturalnews.com/025513.html#ixzz1qwILOxem "Dr. John Lee, author of several books on the health of women, recommended that women wishing to consume soy production eat only miso, tempeh, natto. Tofu can also be eaten provided it is accompanied by fish or some other protein source and some seaweed or kelp to replenish bound minerals. Eating small amounts of these foods will provide the cancer protective effects of genistein without causing the other potential problems of genistein. Dr. Lee recommended avoiding genistein and isoflavone supplements, and soy protein isolates.'
