Soy, the Soydid truth they dont want you to know

Important paper by Dr. Blaylock exposing soy as the public health hazard that it is.

Yesterday Robert Cohen of put a column on his large non-milk list against Dr. Blaylock and Dr. Mercola's warning against the use of soy products. I believe he did this because he advocates soy milk and sells a machine he calls soy toys. He also has a large calling with 7 Day Adventists who should also receive this rebuttal from Dr. Blaylock. Robert's information was wrong and I couldn't stop him nor could I convince him to allow Dr. Blaylock to show his side so people getting the information could form their opinion having both sides of the debate. Dr. Blaylock has answered Robert. This article is chock full of incredible, life-saving information everyone should have. I'm putting it on my lists but I hope
that others who have lists will, in fact, also share it, publish it and saturate the globe with it. Dr. Blaylock's web site with his books is and he also has an excellent newsletter. Also for more information on MSG go to Dr. Blaylock can be seen in the movie Sweet Misery: A Poisoned World ( Stay tuned for Sweet Remedy, coming soon.

Dr. Blaylock's rebuttal was very necessary because "Truth" always comes first, and we're talking about people's lives. It's bad enough that industry and professional organizations who are funded by industry mislead the public. And the glutamate people are very powerful and continually put out propaganda to consumers. Dr. Blaylock's information is brilliant and is the truth of the matter.

All my best,

Response to Robert Cohen's Slanderous Statements

I have been sent an e-mail that you have circulated concerning my objections to soy-based foods. I must say your slanderous rantings are that of a three-year old having a temper tantrum, not a reasoned discussion of the issues involved. You portray yourself as a "scientist", but I fail to see your credentials posted. I am a board-certified neurosurgeon, retired Clinical Assistant Professor of Neurosurgey, Visiting Professor of Biology at Belhaven College and have written over 30 papers published in peer-reviewed scientific journals. I serve on the editorial board of the Journal of American Physicians and Surgeons and the Journal of the American Nutraceutical Association.

My recent papers on the connection between excitotoxicity and fluoride neurotoxicity, and autism and the Gulf War Syndrome have received praise from leading authorities in each of these areas of research. I am the co-developer of one of the most commonly used methods for removal of intraventricular meningiomas, for which I am given credit in all major neurosurgical texts, along with my mentor Ludwig G, Kempe, one of the most famous names in Neurosurgey.

I have written three chapters in three medical textbooks as well as three nutrition books for the lay public, one of which you quoted, citing me as an expert in the field. I do extensive study in the field of excitotoxicity.

Since you are now in the business of selling soy products and a soy-milk making machine, I can understand your concern for your financial future. That has nothing to do with science. If your reading public wants an excellent review of the dangers of soy I suggest they read Dr. Kaayla Daniel's newly released book- The Whole Soy Story. You rambling defense of soy safety falls far short of science for a number of reasons. Aspartic acid, which is a naturally occurring amino acid, that, despite your statement that it is an essential amino acid, is not. It can be synthesized from oxaloacetate and glutamate via transamination. What you and many of the defenders of excitatory amino acid safety cannot seem to understand, or refuse to understand, is that free amino acids act differently than those occurring in whole foods.

Digestion breaks most proteins into amino acids only at a very slow rate. I quote Guyton's Textbook of Medical Physiology, page 794- " As a result the normal rate of absorption... (amino acid absorption is determined) by the rate at which they can be released from the proteins during digestion. For these reasons, essentially no free amino acids can be found in the intestine during digestion." When soybeans are processed, the excitotoxic amino acids (glutamate and aspartate) are not only released, they are concentrated. This is especially so in soy protein isolates and soy protein concentrates-which are used in soy milk. This means that your figures on the glutamic and aspartic acid contents is much lower than in fact exist in your product.

Olney and others have shown that human blood levels of glutamate increase as much as 20X on glutamate loading with concentrations found in such hydrolyzed proteins. These high blood levels are transferred into the human brain, especially under certain circumstances. Even in the completely normal brain, glutamate, aspartate and other excitotoxins can enter the brain via the circumventricular organs, which includes the hypothalamus. As you certainly know, or should know, one of the most sensitive structures in the brain is the arcuate nucleus. It is easily destroyed by levels of glutamate found in hydrolyzed proteins and this has been proven in laboratory studies.

It is also known that the blood-brain barrier contains glutamate receptors and that free glutamate at these concentrations, can open the barrier, allowing these high levels of glutamate to freely enter the brain. It is also known that a multitude of conditions open the barrier, including strokes (both gross and silent), brain injury, brain tumors, certain pesticides, mercury, lead, autoimmune disorders (lupus, rheumatoid arthritis, etc), radiofrequency radiation (cell phones), seizures, multiple sclerosis and infections. Anyone with these conditions should avoid products that contain high levels of excitotoxins, such as hydrolyzed soy products. T his constitutes a large percentage of the population.

In addition, pregnant women should avoid such excitotoxin-containing products, since the placenta concentrates the glutamate, exposing the baby to much higher levels of glutamate than the mother. This has been proven. It has also been proven, that the baby's brain is 5X more sensitive to excitotoxin exposure than is the adult brain and that humans are 4X more sensitive than the next most sensitive animal species. And this is under the best of conditions.

It has been shown that inflammation dramatically increases the toxicity of excitotoxins on the brain, especially in small children. This means that any inflammatory condition, virus, bacterial infection or immune disorder, will increase a person's and especially a baby's risk of injury. Since the human baby's brain undergoes its most rapid growth and development from the last trimester of pregnancy through the first 2 years of life, it is most at risk from food-based excitotoxins, such as hydrolyzed soy.

A number of recent studies have shown that excess glutamate exposure during this period of "brain growth spurt" can alter the develop ment of the child's brain, especially neuroendocrine, cognitive, behavioral and language functions.

I am sure many of your readers are not aware that one of the earliest finding during glutamate research was that newborn animals fed glutamate developed gross obesity. This has been repeated numerous times and is used in obesity studies. An international panels of neuroscientist cited this as a possible reason for the obesity epidemic in the developed world. With the dramatic increase in glutamate food additives and consumption of soy products, especially soy based formula and soy milk by babies and small children, is is no wonder we are seeing this epidemic of childhood gross obesity and diabetes. Experimentally, glutamate exposure in these same doses can induce diabetes in animals.

Experiments have also shown that early exposure to glutamate can alter-permanently-the baby's vascular reactivity. This would have major implications in cardiovascular disease. Likewise, early exposure to higher levels of glutamate, equal to that of food-based excitotoxins, results in behavioral problems, endocrine disruption, increased susceptibility to seizures early in life and alterations in lipid profiles that increase the likelihood of cardiovascular disease later in life. In fact, newer studies have shown that elevated blood glutamate significantly increases free radical generation in the endothelial lining of blood vessels-the very mechanism that causes atherosclerosis.

Recent research has also shown that many tissues and organs in the body contain glutamate receptors and that overstimulation of these receptors can cause a number of clinical problems. For example, glutamate receptor stimulation of pulmonary tissues can result in bronchiospasm (as in asthma) and worsening of pulmonary function in those with lung diseases. The heart muscle and heart conduction system (AV and SA nodes) also contain numerous glutamate receptors. As I pointed out, the pancreas (ilets of Langerhans) also contain abundant glutamate receptors, and explains the resulting diabetes.

Even more frightening is the recent discovery that glutamate greatly enhances the growth of a number of cancers-especially brain cancers, such as the glioblastoma and malignant astrocytoma. Breast, lung and ovarian cancers have also been shown to spread and metastasize faster when glutamate levels are elevated. This has been proven, and is beyond dispute.

We know that under certain conditions, glutamate toxicity is greatly increased, which includes low magnesium levels, deficient mitochondrial energy production [such as hypoglycemia, mitochondrial disease, during aging, with all of the neurodegenerative disease (Alzheimer's, Parkinson's and ALS] and most chronic diseases), during inflammation and when associated with other toxins-including mercury, lead, cadmium, aluminum, pesticides, fluoride and industrial chemicals. This would include tens of millions of Americans, who should be avoiding soy products.
While there is a lot more concerning excitotoxins, which can be found in my two books-Excitotoxins: The Taste That Kills and Health and Nutrition Secrets That Can Save Your Life., unfortunately, there is a lot more involved than just excitotoxins. Soybeans and especially their hydrolyzed and processed products, contain high levels of manganese, aluminum and fluoride-all of which are powerful cell toxins, especially for brain cells.

Recent studies have shown that when aluminum is combined with fluoride, which occurs very easily, brain levels of aluminum are doubled. Extensive research connects aluminum in the brain with most of the neurodegenerative diseases. When hydrolyzed as in soy milk, the fluoride and aluminum easily bind, forming neurotoxic fluoroaluminum compounds. The concentration at which this occurs in 0.5 ppm, a very small concentration. Fluoroaluminum compounds interact with G-proteins, which are common cell communication systems, especially in the brain and operate most of the glutamanergic receptors in the brain (glutamate receptors).

I would call attention to a most important study reported in the Journal of the American College of Nutrition in the year 2000. It describes a 25 year study of middle-aged individuals consuming a diet containing tofu, which found a strong association with brain atrophy and cognitive impairment and the consumption of this soy product. Brain atrophy was determined by MRI scans. In fact, low brain weight was seen in 12% of men consuming the lowest amount of tofu and 40% consuming the highest amount. This indicates a dose-response effect, making a stronger case of neurotoxicity. I can go on forever with research and studies showing a significant danger of consuming large amounts of soy products, especially soy milk, but I have other things to do-like research processed food toxicology .

I would hope that Mr. Cohen would in the future refrain from his temper tantrums and childish, slanderous name-calling. Neither I nor Dr. Mercola are idiots, morons or suffering from delusions. What we are not doing is making money selling soy products. I expect this response to appear on your website.

Russell L. Blaylock, M.D.
