Revealing the myths and truths about soy 

More negatives on soy

by the Weston A. Price Foundation 

Due to the acceleration of the adulteration of animal sources of protein, including those labeled "organic," it is important to make sure our readers know that soybeans, which are listed as an ingredient on a variety of processed food product labels, are not a viable source of protein. It is interesting to note that the famous vegan herbalists and naturopaths in recent history never advocated the use of soybeans as a source of dietary protein. Since we have had many requests for a lucid dissertation on soy and its known risks while witnessing many of our associates using soy products, we felt this information is extremely timely. Many people do not do well on a strictly vegan vegetarian diet and need access to unadulterated sources of animal protein. The Weston A. Price Foundation is an invaluable source of accurate information and is a credible advocacy organization for the health benefits of raw, unadulterated dairy products, grass fed beef and natural husbandry practices.

Myth: Use of soy as a food dates back many thousands of years.

Truth: Soy was first used as a food during the late Chou dynasty (1134-246 BC), only after the Chinese learned to ferment soy beans to make foods like tempeh, natto and tamari. 

Myth: Asians consume large amounts of soy foods. 

Truth: Average consumption of soy foods in Japan and China is 10 grams (about 2 teaspoons) per day. Asians consume soy foods in small amounts as a condiment, and not as a replacement for animal foods. 

Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods. 

Truth: Most modern soy foods are not fermented to neutralize toxins in soybeans, and are processed in a way that denatures proteins and increases levels of carcinogens. 

Myth: Soy foods provide complete protein. 

Truth: Like all legumes, soy beans are deficient in the sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine. 

Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets. 

Truth: The compound that resembles vitamin B12 in soy cannot be used by the human body; in fact, soy foods cause the body to require more B12 

Myth: Soy formula is safe for infants. 

Truth: Soy foods contain trypsin inhibitors that inhibit protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted growth and pancreatic disorders. Soy foods increase the body's requirement for vitamin D, needed for strong bones and normal growth. Phytic acid in soy foods results in reduced bioavailabilty of iron and zinc which are required for the health and development of the brain and nervous system. Soy also lacks cholesterol, likewise essential for the development of the brain and nervous system. Megadoses of phytoestrogens in soy formula have been implicated in the current trend toward increasingly premature sexual development in girls and delayed or retarded sexual development in boys. 

Myth: Soy foods can prevent osteoporosis. 

Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths and vitamin D from seafood, lard and organ meats prevent osteoporosis in Asian countries, not soy foods. 

Myth: Modern soy foods protect against many types of cancer. 

Truth: A British government report concluded that there is little evidence that soy foods protect against breast cancer or any other forms of cancer. In fact, soy foods may result in an increased risk of cancer. 

Myth: Soy foods protect against heart disease. 

Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol improves one's risk of having heart disease. 

Myth: Soy estrogens (isoflavones) are good for you. 

Truth: Soy isoflavones are phyto-endocrine disrupters. At dietary levels, they can prevent ovulation and stimulate the growth of cancer cells. Eating as little as 30 grams (about 4 tablespoons) of soy per day can result in hypothyroidism with symptoms of lethargy, constipation, weight gain and fatigue. 

Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years. 

Truth: Soy foods can stimulate the growth of estrogen-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause. 

Myth: Phytoestrogens in soy foods can enhance mental ability. 

Truth: A recent study found that women with the highest levels of estrogen in their blood had the lowest levels of cognitive function; in Japanese Americans tofu consumption in mid-life is associated with the occurrence of Alzheimer's disease in later life. 

Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status. 

Truth: Archer Daniels Midland (ADM) recently withdrew its application to the FDA for GRAS status for soy isoflavones following an outpouring of protest from the scientific community. The FDA never approved GRAS status for soy protein isolate because of concern regarding the presence of toxins and carcinogens in processed soy. 

Myth: Soy foods are good for your sex life. 

Truth: Numerous animal studies show that soy foods cause infertility in animals. Soy consumption enhances hair growth in middle-aged men, indicating lowered testosterone levels. Japanese housewives feed tofu to their husbands frequently when they want to reduce their virility. 

Myth: Soy beans are good for the environment. 

Truth: Most soy beans grown in the U.S. are genetically engineered to allow farmers to use large amounts of herbicides. 

Myth: Soy beans are good for developing nations. 

Truth: In third world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations. 

Soy Dangers Summarized

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 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. Toxic synthetic vitamin D is added to soy milk.

Fragile proteins are over-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.

Doctor Warns: Eat Soy and You’ll Look 5 Years Older
Serious issue
See all Dr Mercola videos  here 
The soy video is the fourth on the right.

By Dr. Mercola

In the early 1990's, soy and soy products exploded onto the supermarket scene with promises of bountiful health benefits. This "new miracle food," soy, was supposed to lower cholesterol, take the heat out of hot flashes, protect against breast and prostate cancer and offer a filling alternative to earth-loving vegetarians.

The problem with these claims?

Most of them are false.

Sadly, most of what you have been led to believe by the media about soy is simply untrue. The sudden upsurge in the recommendation of soy as a health food has been nothing more than a clever marketing gimmick to further reduce the cost and nutritional content of your food.

Sadly, most of what you have been led to believe by the media about soy is simply untrue. The sudden upsurge in the recommendation of soy as a health food has been nothing more than a clever marketing gimmick to further reduce the cost and nutritional content of your food.

For you vegetarians out there staring at the screen in open-mouthed shock, fear not. There are plenty of other healthy vegetarian alternatives, which I will discuss later in this article. What was once considered a minor industrial crop back in 1913 now covers over 72 million acres of farmland. But first, let's examine the dangers and side effects of soy protein isolate and GMO foods.

Soy Protein Isolate -- What is It, and How is it Getting in My Food?

The Soyfoods Association of America has a soy protein "fact sheet" defining soy protein isolate as the following:

"Soy protein isolate is a dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein and nearly carbohydrate and fat-free."

Soy protein isolate can be found in protein bars, meal replacement shakes, bottled fruit drinks, soups and sauces, meat analogs, baked goods, breakfast cereals and some dietary supplements.

Bodybuilders beware: because many weight gainer powders, bars and shakes contain this dangerous ingredient and it can cause troubling side effects such as diminished libido and erectile dysfunction -- and this is just the start. You'll find out more about these disturbing health effects later on in this article.

Even if you are not a vegetarian and do not use soymilk or tofu, it is important to become a label reader. There are so many different names for soy additives, you could be bringing home a genetically modified soy-based product without even realizing it. Here are just a few names soy tends to hide under:

Soya, Soja or Yuba
TSF (textured soy flour) or TSP (textured soy protein)
TVP (textured vegetable protein)
MSG (monosodium glutamate)

Not all textured vegetable protein is made from soy, but a great deal of it is. Lecithin can be made from soy, eggs, sunflower or corn. Be sure to contact the manufacturer to find out which is in your product if the label doesn't reveal this information.

GMO -- Making Soy Even Worse

One of the worst problems with soy comes from the fact that 90 to 95 percent of soybeans grown in the US are genetically modified (GM), and these are used to create soy protein isolate.

Why the genetic tinkering?

Genetically modified soybeans are designed to be "Roundup ready." That's right, they are chemically engineered to withstand heavy doses of herbicides without killing the plant! What does this mean for your health and the health of your unborn or yet-to-be-conceived children? Read on.

GM Soy Can Lead to Hormonal Disruption and Miscarriages

The active ingredient in Roundup herbicide is called glyphosate, which is responsible for the disruption of the delicate hormonal balance of the female reproductive cycle.

"It's an endocrine buster," says UK pathologist Stanley Ewen, "that interferes with aromatase, which produces estrogen."

What's more, glyphosate is toxic to the placenta, which is responsible for delivering vital nutrients from mother to child, and eliminating waste products. Once the placenta has been damaged or destroyed, the result can be miscarriage. In those children born to mothers who have been exposed to even a small amount of glyphosate, serious birth defects can result.

In an excellent summary of glyphosate-related effects by the Pesticide Action Network, Dr. Andreas Carrasco of the Embryology Laboratory, Faculty of Medicine in Buenos Aires, simply and expertly explains the serious risks for unborn children exposed to Roundup-laden GMO soy products.

Amphibian embryos were exposed to a tiny concentration of glyphosate (diluted 5000 fold) and showed the following effects:

"Effects included reduced head size, genetic alterations in the central nervous system, increased death of cells that help form the skull, deformed cartilage, eye defects, and undeveloped kidneys. Carrasco also stated that the glyphosate was not breaking down in the cells, but was accumulating.

The findings lend weight to claims that abnormally high levels of cancer, birth defects, neonatal mortality, lupus, kidney disease, and skin and respiratory problems in populations near Argentina's soybean fields may be linked to the aerial spraying of Roundup."

The long-term effects of the human consumption of genetically modified soy and soy-based products are staggering.

In April 2010, researchers at Russia's Institute of Ecology and Evolution of the Russian Academy of Sciences and the National Association for Gene Security found that after feeding hamsters GM soy for two years over three generations, by the third generation, most lost the ability to have babies!  Now, let's take a close look at some of the health risks to YOU as a result of eating genetically modified soy.

Infertility in Women

Do you want to start a family? Have you had any trouble conceiving, perhaps due to irregular menstrual cycles or endometriosis? Have you ever experienced a miscarriage?

If so, what you're about to read will shock you.

A Brazilian study published in 2009 looked at the impact of soy on the reproductive system of female rats. Female rats fed GM soy for 15 months showed significant changes in their uterus and reproductive cycles, compared to rats fed organic soy or no soy.

Extrapolating the findings to people, women who eat genetically modified soy products, such as the soy protein isolate in processed vegetarian fare, may be more likely to experience severe hormonal disruptions, including an overabundance of estrogen, a hair-growth stimulating hormone, and damage to the pituitary gland.

According to Dr. Stanley Ewen, the female rats fed GM soy probably had an increase in progesterone, which could cause an increase in the number of eggs released during each ovulation cycle.

You might think this would lead to an increase in fertility. However, as discussed in an article by Jeffrey Smith, women who consume genetically modified soy products are at increased risk for developing retrograde menstruation (the menstrual cycle backs up into the body instead of outward), causing endometriosis, which can lead to infertility.

The consumption of soy protein isolate and other soy-based products can also lead to abnormally heavy or longer menstrual periods. This is called menorrhagia and, ironically, some commercials have been popping up with a new pill that supposedly offers the "cure" for this "mystery syndrome."

When in reality the real cure for some women is as simple as removing soy and soy-based products from the diet. The negative effects of soy are not restricted to women, however.

Loss of Libido & Erectile Dysfunction in Men

Guys, do you enjoy protein bars or use a weight gainer shake? If so, be sure to read the label to see if the products you use contain any soy ingredients. Did you know that celibate monks living in monasteries and leading a vegetarian lifestyle find soy foods quite helpful for dampening libido?

Another drawback: Soy has also been linked to erectile dysfunction. The two natural drugs found in soy, genistein and daidzein, mimic estrogen so well that they have been known to cause a variety of alarming side effects in men:

Breast enlargement (gynecomastia)
Decreased facial and body hair growth
Decreased libido
Mood swings and frequent crying jags
Erectile dysfunction
Lowered sperm count

For example, one recent study documented a case of gynecomastia in a 60-year-old man as a result of his soy consumption. Another study showed that juvenile rats exposed to daidzein showed impaired erectile function at maturity.

Men, if you've experienced one or any of these symptoms, soy could be the culprit. Remove it from your diet, but be sure to consult a trusted physician if your symptoms do not improve or get worse as this could be a sign of another serious condition.

The Healthy Aspects of Soy: Fermented vs. Unfermented

In order to back up the claim that soy is a health food, privately funded "researchers" have been quick to point out that Asians, who consume a diet high in soy, have less risk of breast, uterine and prostate cancer. Unfortunately, they leave out two very important

Asians, especially the Japanese, while having a decreased risk of the above-mentioned cancers, have a much higher risk of developing cancer of the esophagus, thyroid, stomach, pancreas and liver!
Asians also consume a diet rich in fermented soy, which is the only type of soy to offer health benefits.

The reason Asians have an increased risk for some cancers is the same reason they do not develop others: unfermented soy. The soy marketing and promotion gurus left out this critical piece of information. Would you rather have one cancer over another? Isn't that like asking whether or not you'd like to be whacked in the head with a two-by-four vs. a wooden stick?

You might be asking yourself what the big difference is between consuming a fermented soy product such as, say, tempeh, vs. tofu or a veggie burger. I'm here to tell you, the difference is night and day.

Unfermented AND fermented soy contains hormonal mimics in the form of isoflavones which can not only disrupt delicate hormone systems in your body, but also act as goitrogens, substances that suppress your thyroid function. When the thyroid is suppressed, a host of health problems result, namely:

Anxiety and mood swings
Difficulty losing weight
Difficulty conceiving children
Digestive problems
Food allergies

And so much more. No wonder soy can lead to thyroid, esophagus and stomach cancer! Unfermented soy is also chock full of phytic acid, an "antinutrient" responsible for leeching vital nutrients from your body. Phytic acid also blocks the uptake of essential minerals such as calcium, magnesium, copper, iron and zinc especially.

Now, fermented soy products do provide health benefits.

As I mentioned in my previous article, some examples of healthful fermented soyproducts are as follows:

Tempeh, a fermented soybean cake with a firm texture and nutty, mushroom-like flavor.
Miso, a fermented soybean paste with a salty, buttery texture (commonly used in miso soup).
Natto, fermented soybeans with a sticky texture and strong, cheese-like flavor.
Soy sauce, which is traditionally made by fermenting soybeans, salt and enzymes; be wary because many varieties on the market today are made artificially using a chemical process.

For those of you who enjoy tofu, I'm sorry to say it didn't make this list because tofu is an unfermented soy product.

So, What Are The Health Benefits of Fermented Soy Products?

The claim that soy products can prevent osteoporosis, decrease your risk of cardiovascular disease and dementia and protect you from cancer of the prostate, lung and liver is actually true, but ONLY if the soy is fermented.


The process of fermenting soy destroys the above-mentioned dangerous substances, thereby making it fit for consumption. Also, fermented soy products such as those listed above are a rich source of vitamin K2, a vitamin that works in harmony with vitamin D to keep you healthy. Vitamin K regulates your body's blood clotting ability and helps prevent cancer, osteoporosis and heart disease. And vitamin D is essential to the function of every system in your body.

Warning to Vegetarians about the Risk of Mineral Deficiency

Since phytic acid or phytates sap the nutrients from your body, if you're eating a vegetarian diet that has replaced meat with mostly unfermented soy such as veggie burgers containing GMO soy protein isolate, you are at risk for severe mineral deficiency.

In addition to this nutrient loss, many processed veggie burgers and the like are packed with harmful artificial flavorings, particularly MSG and textured vegetable protein products to give them their strong "meat" flavor.

What's even worse is the process soy has to go through to become soy protein isolate. Acid washing in aluminum tanks, which is designed to remove some of the antinutrients (but the results often vary widely), leeches aluminum into the final product. Aluminum can have adverse effects on brain development and cause symptoms such as:

Antisocial behavior
Learning disabilities
Alzheimer's Disease and Dementia

As I mentioned in a previous article about soy, this makes processed vegetarian fare more palatable, but far from nutritious. Vegetarians have plenty of options for well-rounded, nutritious meals without needing to eat soy or soy-based products.

Beans are an inexpensive, protein-rich food that can be eaten alone, added to salads or served as a side dish. Be sure to purchase organic dried beans and cook them at home to avoid the adverse health effects of eating canned food. Ideally is it also best to soak them for at least 12 hours before cooking them.
Nuts are also an excellent source of protein. For optimal health benefits, reach for organic nuts such as almonds or walnuts, instead of overly processed mixed nuts.
Quinoa is a gluten free grain that can be enjoyed as a cereal, side dish or added to homemade vegetable stews as a thickener.
Flaxseed, which is rich in essential omega 3 fats like ALA, is an excellent source of protein. Add it to salads or sprinkle it over yogurt to infuse your meal with vital nutrients. However, it is important to grind flax seeds just prior to eating them because100 percent of commercially ground flaxseeds are rancid. Hemp seeds are also an excellent source of protein.

Hope for the Lactose Intolerant

If you suffer from lactose intolerance and have been replacing milk with soy, you have three more healthful options: Almond milk, and now hemp milk. All are nutritious alternatives to soy, and almond milk has a richer, heartier flavor. Hemp milk is a very creamy, high protein alternative to soymilk, and it's easy to blend your own by whizzing up hemp seeds and water in a high-speed blender.

Babies -- Birth Control in a Bottle

As stated in a number of previous articles, soy formula is one of the most dangerous foods you can feed your baby!

"In 1998, investigators reported that the daily exposure of infants to isoflavones in soy infant formula is 6 to11 times higher on a body-weight basis than the dose that has hormonal effects in adults consuming soy foods. Circulating concentrations of isoflavones in infants fed soy-based formula were 13,000 to 22,000 times higher than plasma estradiol concentrations in infants on cow's milk formula."

What does this mean? Feeding your infant soy-based formula can cause a host of health problems including:

Behavioral problems
Food allergies and digestive distress
Early puberty and fertility problems (including the inability to menstruate)
Precocious puberty for girls and gynecomastia (man boobs) for boys
Thyroid disease

As I concluded in my article on infant formula, babies who are fed exclusively from the breast from birth to six months enjoy health benefits such as:

Lower risk of respiratory tract and middle ear infections
Lower risk of eczema
Lower risk of obesity
Added protection against heart disease, diabetes, asthma, and allergies
Improved brain function and immune system function

Soy formula is also laden with toxic chemicals such as aluminum and manganese, which can cause both physical and mental health problems, learning disabilities, brain damage and behavioral problems. If, for some reason, you are unable to breastfeed or have adopted a baby, look into these recipes for homemade infant formula.

School Lunch -- Children's Nutrition Left Behind

In order to comply with new US Government standards, soy products are now being used to replace whole, nutritious foods in school lunches. Due to the decreased fat content of soy, it is touted as a healthful alternative to the meat and dairy of yesterday's hot meal.

Nothing could be further from the truth.

Soy added to your child's hot lunch depletes the necessary nutrients needed for healthy growth and has been linked to learning disabilities. I encourage you to watch this sobering video to learn more about the dangers in your child's school lunch. Do your children a favor and send them to school with a healthy, home-packed meal.

Senior Citizens -- Aging Less Gracefully

According to a study done by Dr. Lon White of the Hawaii Center for Health Research, senior citizens who consumed a lot of tofu in mid-life were more likely to experience accelerated brain aging and a more pronounced loss of cognitive function.

"What's more," said Dr White, "those who ate a lot of tofu, by the time they were 75 or 80, looked five years older."

If you're heading toward your golden years and are looking to avoid soy protein, become a label reader. Meal replacement drinks like Ensure are filled with soy protein and are best avoided. If you're looking for a wholesome, nutrient-filled vegetarian meal replacement drink, try my 100% Pure Pea Protein supplement. As you can see, unfermented soy is anything but a health food.

Do your own research, try eliminating it from your family's diet and judge the results for yourself. Remember, an educated consumer is an armed consumer. Big companies can only produce and sell these harmful products as long as you're buying them.

Vote with your wallet by spending your money on healthier alternatives!

More negatives on soy
"Against the backdrop of widespread praise...there is growing suspicion that soy - may pose some health hazards," writes Marian Burros, a leading food writer for the New York Times. More than any other writer, Ms Burros's endorsement of a low-fat, largely vegetarian diet has herded Americans into supermarket aisles featuring soy foods. Yet her January 26, 2000 article, "Doubts Cloud Rosy News on Soy", contains the following alarming statement: "Not one of the 18 scientists interviewed for this column was willing to say that taking isoflavones was risk free." Ms Burros did not enumerate the risks, nor did she mention that the recommended 25 daily grams of soy protein contain enough isoflavones to cause problems in sensitive individuals, but it was evident that the industry had recognized the need to cover itself.

Because the industry is extremely exposed...contingency lawyers will soon discover that the number of potential plaintiffs can be counted in the millions and the pockets are very, very deep. Juries will hear something like the following: "The industry has known for years that soy contains many toxins. At first they told the public that the toxins were removed by processing. When it became apparent that processing could not get rid of them, they claimed that these substances were beneficial. Your government granted a health claim to a substance that is poisonous, and the industry lied to the public to sell more soy."

The "industry" includes merchants, manufacturers, scientists, publicists, bureaucrats, former bond financiers, food writers, vitamin companies and retail stores. Farmers will probably escape because they were duped like the rest of us. But they need to find something else to grow before the soy bubble bursts and the market collapses: grass-fed livestock, designer vegetables...or hemp to make paper for thousands and thousands of legal briefs.

Its a big industry Soy is, but just like smoking was and still is, the business aspect will keep this potentially harmful ingredient in our food chain with its potential toxic and health damaging effects being spread throughout the populations with out our knowing. At least we cigarettes we could smell smoke and move out of the way. With soy we choke it down not knowing the vast amount of serious health damaging potential ingredients we are putting into perhaps every cell in our bodies. To use Soy in a meal replacement Weight Loss Shake is one of the most reprehensible acts I have ever seen in health care. Someone somewhere in the chain of making these products has got to know the potential harm they are inflicting on an innocent population!

One of the worst effects of Soy, in my opinion, is that is decreases telomerase, the enzyme that rebuilds telomere units to keep us younger. Shutting down telomerase should in all likelihood accelerating aging. Not only does Soy have the potential to damage our health in so many ways, now the chance of our aging faster because of it is gasoline on the the bonfire of toxins it has the very real possibility of afflicting us with. Soy-Cigarettes-Asbestos I believe will soon be synonymous with the real potential health hazards of our generation.

I wonder why this type of information isn't more widespread. Do you think lobby groups and GREED might have something to do with it?

Watch out my friend, big business does not care about your health. They care about how much they can pry out of your wallet.

Be aware of what you consume. BEWARE of what you consume.

Stay healthy friends,
