Consuming Genetically-Modified Soy is a Very, Very Risky Proposition

There is a lot of debate about whether soy products are healthy or not to eat.

Some people think they are fine, while others believe that their high levels of phyto-estrogens cause hormonal and reproductive problems.

My take on it is that soy products are okay to consume but they need to be fermented – tofu and miso, being two examples – and I only eat small amounts of them.  Soy milk is not fermented and is something that I completely avoid, even if it is organic.

One issue that is indisputable is that genetically-modified soy presents very, very serious health risks.

And given that 91% of the soy produced in the U.S. is genetically-modified, it is something that everyone needs to be aware of.

Here are the frightening facts about genetically-modified soy.

1) According to Russian researchers at the Institute of Ecology and Evolution of the Russian Academy of Sciences and the National Association for Gene Security, hamsters that were fed very high GM-soy diets for two years over three generations produced horrifying results.

By the third generation, most of the hamsters lost the ability to have babies, showed slower growth, and suffered a high mortality rate among the pups.

Furthermore, some in the third generation even had hair growing inside of their mouths!!!

2) In 2005, Irina Ermakova of the Russian National Academy of Sciences reported that more than half the babies from mother rats fed GM-soy died within three weeks.

Even more shocking was when Ermakova fed male rats genetically-modified soy, their testicles changed from the normal pink to dark blue!

3) According to researchers at York University in England, soon after genetically-modified soy was introduced into that country, soy allergies skyrocketed 50%.

4) The Weston A. Price Foundation has filed a lawsuit against the State of Illinois on behalf of prisoners who suffered serious health complications by being fed excessive amounts of soy products. In 2004, the state of Illinois began using large amounts of soy in prison menus in order to save money and use less meat.

The lawsuit claims that the soy being fed to the plaintiffs, in the amounts being fed to them, constitutes cruel and unusual punishment in violation of the eighth amendment to the Constitution, as well as a denial of plaintiffs’ liberty in violation of their due process rights under the fourteenth amendment to the Constitution.

The prisoners’ health complaints include chronic and painful constipation alternating with debilitating diarrhea, vomiting after eating, sharp pains in the digestive tract, especially after consuming soy, passing out, heart palpitations, rashes, acne, insomnia, panic attacks, depression and symptoms of hypothyroidism, such as low body temperature (feeling cold all the time), brain fog, fatigue, weight gain, frequent infections and thyroid disease.

Even though we do not know for certain whether the soy being fed to these inmates was genetically-modified or not, I cannot imagine that a prison is going to feed them organic soy, especially when they are trying to save money.


Just remember that approximately 75-80% of the food on supermarket shelves is genetically-modified, and conventional food companies put soy into more products than you can imagine.

If you’re going to eat any soy product, please make sure that it is certified organic.

    I have read so many horrifying articles about soy, and have felt the effects of soy milk that I think it’s best not to consume any soy products at all, if possible. I just finished reading an article by Dr. Joseph Mercola about the dangers of soy.

    I have even joined the campaign to get Starbucks to remove soy milk and replace it with coconut milk and almond milk. To learn more about that effort, you can go to Starbucks’ website.

    Excellent and informative article. I hadn’t know about some of those results. Given how severe they are, it’s critical that consumers educate themselves. Thanks for spreading the word!

    Great post. It is for the first time I am reading about dangers of soy, and for me a big tofu lover this is very sad. Indeed I found that it is very dangerous to consume GModified soy.

    Max, one small correction: As one who has made his own tofu from homemade non-GMO soymilk, I am sure tofu is not a fermented product. Interestingly, while living in Japan although most of tofu is made from North American soybeans, almost all were labeled as non-GMO. For some reason, Japanese grown soybeans are several times more expensive than N. American. Other examples of fermented soybean products (in addition to miso) are natto and tempeh.

    Often overlooked is the potential for severe migraines, as I am well-aware. I had over 50 migraines in a year until we discovered I was having a problem with soy. My left eye was drooping, and my MRI now shows I have white matter ‘dots’ on my brain from all of the headaches. Apparently these are typical for migraine sufferers and some studies show the presence of these dots increase stroke risk by as much as 50%. When I cut the soy, the migraines stop.

  • Casey says:

    I have a question about fermented soy. I don’t understand how, even in small amounts, when consumed why it does not have the same effects on our bodies as non-fermented soy? They are both GMO when non organic correct?

    Thanks, Casey

  • Ray says:

    Thanks Max. I love the story and i love The Weston A. Price Foundation for what it all does like this lawsuit and bailing out farmers who sell Raw Milk and so many other things

  • Thanks for sharing this info. Even though critics deny any ill-effects of GMOs, wouldn’t we have been better off waiting for longitudinal study results before GMOs were on our plates? Big corporations, politics and money are much more powerful than the consumer today. But we can fight back with getting the word out, one voice at a time. Why don’t we boycott these foods on a national level to show our concern? Money talks when it ceases to flow in their direction.

      Hi Debra,

      My pleasure and please spread the word about this, so more people are aware of the risks of GM-soy (and all GM-foods).

      Live well,
