IS SOY AS DANGEROUS AS SOME SAY? (Updated 1st May 2013)

I came across this article. If any one finds a rebuttal article, I’ll include it to give balance. You can’t make an honest decision without knowing the evidence from both sides.

The Dangers of Soy Are Real–and Much Worse Than You Might Think

Promoting soy foods as health foods while ignoring the dangers of soy and soy derivatives should be considered a crime against humanity. If you think this statement is too extreme, read this article to the end, and then see what you think!

The dangers of soy are thoroughly documented in the scientific literature, which makes it hard to believe that many health and fitness communities and counselors, and most health food stores, still promote soy products as ultra-healthy foods.

Hopefully this harmful misrepresentation of soy foods will begin to change as the dangers of soy become better known.

A Summary of the Dangers of Soy

  • Soybeans and soy products contain high levels of phytic acid, which inhibits assimilation of calcium, magnesium, copper, iron, and zinc.
  • Soaking, sprouting, and long, slow cooking do not neutralize phytic acid.
  • Diets high in phytic acid have been shown to cause growth problems in children.
  • Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders.
  • Test animals showed stunted growth when fed trypsin inhibitors from soy.
  • The plant estrogens found in soy, called phytoestrogens, disrupt endocrine function, that is, the proper functioning of the glands that produce hormones, and have the potential to cause infertility as well as to promote breast cancer in adult women.
  • Hypothyroidism and thyroid cancer may be caused by soy phytoestrogens.
  • Infant soy formula has been linked to autoimmune thyroid disease.
  • Soy has been found to increase the body’s need for vitamin B12 and vitamin D.
  • Fragile soy proteins are exposed to high temperatures during processing in order to make soy protein isolate and textured vegetable protein, making them unsuitable for human digestion.
  • This same process results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines. (Doesn’t sound like anything anyone would want to eat, does it?)
  • MSG, (also called free glutamic acid), a potent neurotoxin, is formed during soy food processing. Many soy products have extra MSG added as well. (See video on the dangers of Aspartame, MSG’s chemical first cousin.)
  • Soy foods contain elevated levels of toxic aluminum, which negatively effects the nervous system the kidneys and has been implicated in the onset of Alzheimer’s.

If this list of the dangers of soy isn’t enough to make you run out the door of your local health food store, keep reading. It gets worse.

Feeding Babies Infant Soy Formula Is Like Giving Them Birth Control Pills

  • It’s been found that babies given infant soy formulas have 13,000 to 22,000 times more estrogen than babies fed milk-based formulas.
  • Babies fed exclusively on infant soy formula are receiving the estrogenic equivalent (based on body weight) of at least four or five birth control pills per day! You read that right. Four or five birth control pills per day! Here’s the reference so you can check this out for yourself. [Irvine, C. et al., “The Potential Adverse Effects of Soybean Phytoestrogens in Infant Feeding”, New Zealand Medical Journal May 24, 1995, p. 318.] By contrast, dairy-based infant formula contains almost no phytoestrogens, nor does human milk, even when the mother eats soy products. (Sally Fallon & Mary G. Enig, Ph.D.)
  • There has been an increase of delayed physical maturation among boys, including lack of development of sexual organs.
  • Conversely, many girls today show signs of puberty, such as breast development and pubic hair, before the age of eight, and some even before the age of three.
  • Both of these abnormal conditions have been linked to the use of soy formulas as well as to exposure to “environmental estrogens” such as PCBs (polychlorinated biphenyls) and DDE (dichlorodiphenyldichloroethylene)a breakdown product of DDT.

Would you want to knowingly expose your tiny infant to the dangers of soy formula?

But Don’t Oriental Cultures Eat Lots of Soy?

It seems that historically, Oriental cultures consumed mostly traditionally fermented soy products such as miso, tempeh, natto, shoyu and tamari. (Tofu is not fermented, and falls into the dangerous soy foods category.) They consumed these soy foods in small amounts, as a condiment.

  • Soy foods account for only 1.5 percent of calories in the Chinese diet, researchers found. (1977 Chang KC)
  • The actual soybean consumed today is not the same one used by traditional Oriental cultures.

Problems with Soy Protein Isolate

  • Furthermore, modern soy foods are very different from those consumed traditionally in Asia. Most are made with soy protein isolate (SPI), which is a protein-rich powder extracted by an industrial process from the waste product of soy oil manufacturing. It is the industry’s way of making a profit on a waste product. The industry spent over 30 years and billions of dollars developing SPI.
  • In feeding studies, SPI caused many deficiencies in rats. That soy causes deficiencies in B12 and zinc is widely recognized, but the range of deficiencies was surprising.
  • Although SPI is added to many foods, it was never granted GRAS status, meaning “Generally Recognized as Safe”. The FDA only granted GRAS status to SPI for use as a binder in cardboard boxes. During the processing of soy, many additional toxins are formed, including nitrates (which are carcinogens) and a toxin called lysinoalanine. It was concerns about lysinoalanine in SPI that led the FDA to deny GRAS status for SPI as a food additive.
  • In spite of all these dangers of soy protein isolate, SPI is the basic ingredient of soy infant formula. The FDA even allows a health claim for foods containing 6.25 grams SPI per serving.

Scientific Studies Showing Adverse Effects of Dietary Soy

The Weston Price Foundation has a list of studies carried out from 1971 to 2003 showing the adverse effects of dietary soy.

To give you an idea of how condemning these studies are, here are just a few summaries. There are over 50 more!

Fort P and others. Breast feeding and insulin-dependent diabetes mellitus in children. J Am Coll Nutr 1986;5(5):439-441. Twice as many soy-fed children developed diabetes as those in a control group that was breast fed or received milk-based formula. It was based on this study that the American Academy of Pediatrics took a position of opposition to the use of soy infant formula. This objection was later dropped after the AAP received substantial grants from the Infant Formula Council.

Hawkins NM and others. Potential aluminium toxicity in infants fed special infant formula. J Pediatr Gastroenterol Nutr 1994;19(4):377-81 (1994). Researchers found aluminum concentrations of 534 micrograms/L in soy formula, as compared to 9.2 micrograms/L in breast milk. The authors concluded that infants may be at risk from aluminium toxicity when consuming formula containing more than 300 micrograms/L.

Sheehan DM and Doerge DR, Letter to Dockets Management Branch (HFA-305) February 18, 1999. A strong letter of protest from two government researchers at the National Center for Toxicological Research urging that soy protein carry a warning label rather than a health claim.

White L. Association of High Midlife Tofu Consumption with Accelerated Brain Aging. Plenary Session #8: Cognitive Function, The Third International Soy Symposium, Program, November 1999, page 26. An ongoing study of Japanese Americans living in Hawaii found a significant statistical relationship between two or more servings of tofu per week and “accelerated brain aging.” Those participants who consumed tofu in mid life had lower cognitive function in late life and a greater incidence of Alzheimer’s and dementia.

Strom BL and others. Exposure to soy-based formula in infancy and endocrinological and reproductive outcomes in young adulthood. JAMA 2001 Nov 21;286(19):2402-3. Although reported in the media as a vindication of soy infant formula, the study actually found that soy-fed infants had more reproductive problems and more asthma as adults.

The FDA Had the Scientific Information about the Dangers of Soy but Chose to Ignore It

You might think that people probably just didn’t know about the toxic effects of soybeans, that the food industry and the FDA must have just been misinformed about the supposed benefits, and very real dangers, of soy. Unfortunately for the FDA’s credibility, this was not the case.

If you simply do a search on ‘soybean’ at the Poisonous Plant Database of the United States FDA’s Center for Food Safety and Applied Nutrition, you can see this information yourself.

Right there in black and white you’ll find 288 studies on soy, many focused on the toxic properties and effects of soybeans. It’s not very easy to understand or get access to the actual studies, but it is cause for great concern that the FDA had this information and knowingly chose to ignore the dangers, just as it has done with so many other additives and pharmaceuticals.

It’s tragic to think of the human suffering that could have been avoided had the FDA just been more cautious and listened to their scientific advisors.

And it’s mind-boggling to think that the very federal agency whose mandate is, among other things, “to promote and protect the public health, to monitor products for continued safety after they are in use, and to help the public get the accurate, science-based information needed to improve health,” could knowingly do the apparent opposite.

This is one more example that highlights the need to educate yourself by finding good sources of information to base your health and diet decisions on, rather than relying on the FDA’s stamp of approval.

Do You Still Think We’re Exaggerating the Dangers of Soy?

When there is a pretty good possibility that something is harmful, as is the case with soy, common sense dictates that it’s better to avoid it!

The corporations who make billions from selling soy would like us to believe that until the dangers of soy are proven beyond a shadow of a doubt, we shouldn’t worry about them. This reminds me of Russian roulette: if a gun had a hundred chambers, and only one was loaded, I wouldn’t risk putting it to my head and pulling the trigger. Would you?

Or, as Roger Eichman, DDS, succinctly summed up the precautionary principle: “The precautionary principle requires action once the possibility of harm exists. It does not require proof beyond a shadow of a doubt.”

There’s more than enough sound scientific evidence to convince me. I used to think soy was a good dietary choice, but not anymore. I quit eating it a long time ago.

UPDATE  (1st May 2013)   This article perhaps goes someway to give some balance to the discussion. You make up your own mind.

Soy Protein :: The Real Modern Research

Soy protein is widely used since 1959. In normal life there are so many soy foods which contain soy protein. This is  proved to be really good while thinking of its benefits. Commercially there are so many products which contain saturated or textured soy protein. Soy protein may have many benefits over some minor side effects to people with soy protein allergy.

What is soy protein?

Soy protein is such a protein body which is mainly found in soybeans and secondarily in other pulses. When we talk about soy foods, we found many salad dressings, special soy milk, soy powered and many other things which contain high amount of soy protein in it. Here I am giving away a brief list of soy foods which contain soy protein.

  1. Salad Dressings
  2. Soups
  3. Soy Beverage Powder
  4. Meat Analogues
  5. Cheese
  6. Non-Dairy Creamer Products
  7. Infant Formulas

Soy Protein Varieties

Varieties or Proteins like Soy can be best explained in the following heads.

Soy Protein Isolate

The Soy Protein Isolate is highly refined form of soy protein which is also more saturated than the other soy protein varieties. Soy Protein Isolate contains normally more than 90% of pure, refined soy protein. Soy protein isolate is formed or produced using soy floor while isolating other non-protein components and fats which were present in the source.

Concentrate Soy Protein

The soy protein concentrate is mainly the form of protein which is extracted from soy floor however while extracting process the water-soluble carbohydrates are removed. In this form of soy protein the pure protein can be found around 70%.

Soy Protein  Effects

Soy Protein has many good and bad effects over human body. In my personal opinion the soy protein has more benefits than the side effects. Let me explain the dangers of soy protein as well as benefits of it.

Soy Protein Side Effects or Dangers

Textured Soy Protein Soup

Many people has soy food allergy mostly in United States of America and Canada. People do want to know that what type of side effects or dangers are there in soy protein or soy products. The main danger of soy protein is the methods or processing the soy foods, normally soybeans are not as much dangerous as soy protein isolate or soy protein concentrate, Its due to the way, the industries process soy proteins from the raw source. The primary method contains some high temperature and high pressure methods with chemical processors.  During the processing of soy products, many good ingredients are removed and such a chemical results is occurred that the resulted soy products may stop or resits to let the body absorb many mineral particulars such as Zinc, Copper, Magnesium and Iron which are necessary to the human body to do certain functions.

Benefits of Soy Protein

  1. This do have such an energy inside which really imitate like meat products.
  2. According to FDA, this protein do reduce LDL Cholesterol from the human body, hence it lowers the risk of heart problems.
  3. Soy Protein Amino Acids inside, so improves the effect of other foods too.
  4. Soy protein, reduces the risk to many serious diseases such as Colon cancer, Osteoporosis and  Prostate Cancer.


What you should know

, also marketed as Nutrasweet, Spoonful, Canderel and Equal as well as being a common additive in many foods and drinks (sometimes shown as the E number E951). Aspartame acts as a sugar replacement.
The EPA announced that there is an
epidemic of Multiple Sclerosis and Systemic Lupus and they did not know what toxin was causing this to be rampant across the US. Scientists have now found the answer to this question – Aspartame.

ASPARTAME. In temperatures exceeding 86 degrees F. the wood alcohol in Aspartame converts to Formaldehyde, and then to Formic Acid. Patients with methanol toxicity caused by drinking 3-4 Diet Coke or Diet Pepsi per day, have been caused to have MS or Systemic Lupus symptoms. In Systemic Lupus and MS case triggers by Aspartame, the victim is unaware that Aspartame is the culprit but continued use, in the case of Lupus, can be life threatening. On stopping Aspartame these patients usually lose all or most of their symptoms. Unfortunately the disease cannot be reversed.

Symptoms of Aspartame Disease are: Fibromyalgia symptoms, spasms, shooting pains, cramps, vertigo, numbness in the legs, dizziness, headaches, tinnitus, joint pain, depression, anxiety attacks, slurred speech, blurred vision, blindness and memory loss. Formaldehyde is classed with chemicals like Arsenic and Cyanide  DEADLY POISONS!
Kills as surely as the other two, only slower and causes all kinds of
neurological problems. It changes the brain s chemistry and is a reason for severe seizures. According to the College of Physicians, the Phenylalanine in Aspartame depletes Serotonin, and causes manic depression, panic attacks, rage and violence.

Aspartame is especially deadly for Diabetics, as it makes the food sugar level go out of control causing patients to suffer severe memory loss, coma and death. The memory loss is due to the fact that Aspartic Acid and Phenylalanine are neurotoxic without the other amino acids found in protein. Thus it goes past the blood brain barrier and deteriorates the neurons of the brain. Dr Russell Blaylock, neurosurgeon, said The ingredients stimulate the neurons of the brain to death, causing brain damage of varying degrees . Aspartame disease is rampant in the US, and most probably in 90 other countries (Including the UK and most of Europe) where over 5000 products containing Aspartame are sold. Aspartame Disease could also be to blame for Gulf War Syndrome. Several thousand pallets of diet drinks were stored and consumed in the heat of 120 degrees F (remember the heat liberates the methanol at 86 degrees F) Most Gulf War Syndrome symptoms are identical to Aspartame Poisoning. Dr. H. J. Roberts, world expert on Aspartame poisoning, says it also escalates Alzheimer s disease. Women as young as 30 are admitted to hospices with Alzheimer s disease! Dr Roberts also says that consuming Aspartame during conception can cause birth defects. According to Dr. Louis Elsas. Paediatrician Professor of Genetics the Phenylalanine concentrates in the placenta causing mental retardation. Another neurosurgeon said that when brain tumours were removed, high levels of Aspartame were found in them. Aspartame makes you crave carbohydrates, and stores in the fatty tissue, so even though it is used as a diet aid, it actually makes you FAT!

MONSANTO, the creator of Aspartame (the largest G M food company) knows all about the dangers, they fund the American Diabetics Association, Congress, and the Conference of the American College of Physicians. As proven in 1996, the American Diabetic Association takes money from the food industry to endorse their products. Therefore they cannot criticise MONSANTO. A bill that tried to warn people about the dangers of ASPARTAME, was killed off by the powerful drug and chemical lobbies, letting loose the hounds of disease and death on an unsuspecting public. And that includes all of us here in the UK! – Having read this, would you trust MONSANTO S GM food?

So, if it s labelled Sugar Free   DON T HAVE IT!

Article from Positive Health magazine  July 1999

Aspartame – Not all Sweetness and Light

Many patients diagnosed with Multiple Sclerosis (MS) may in fact be suffering from some of the 92 already documented neurological symptoms now being attributed to methanol toxicity or Aspartame Disease , including fibromyalgia, headaches, vertigo, tinnitus, numbness in the legs, blurred vision, slurred speech, depression and memory loss. In addition, an analysis of the incidence of brain tumours, carried out my Professor John Olney, Washington University, St Louis, USA, has demonstrated that there was an abrupt 10% increase in cases following the introduction of Aspartame in dry goods in 1981 and soft drinks in 1983.

Methanol, the toxin present in Aspartame, belongs to the same class of poisons as Cyanide and Arsenic. It is readily converted into formaldehyde and then into Formic Acid (the poison contained in the sting of Fire Ants) when subjected to prolonged storage of temperatures of 86 Degrees F or over in the body, this can result in metabolic acidosis and methanol toxicity affecting the brain, retina and nerves.

It is interesting to note that Aspartame is manufactured by the NutraSweet Corporation, a subsidiary of Monsanto, who, it is believed, are fully aware of the dangers of their product. However, as Monsanto also funds the American Diabetics Association, the American Dietetic Association, Congress and the Conference of the American College of Physicians, there appears to be a conspiracy of silence with regard to the dangers of this artificial sweetener which is contained in over 5,000 sugar-free products sold under the brand names of NutraSweet, Canderel, Equal and Spoonful. (Also listed as E Number E951)
The general advice is to read the labels and avoid!
