The title of this article is misleading since I already knew about soy and suspected that fermented soy was harmful. However, yesterday, I felt just how dangerous it is. I have been cleansing my body with herbs, short fasts and a fruitarian diet so my system is a lot cleaner than usual. I feel the blood flowing through my head and many parts of my body. It’s a really great feeling that I promise to share with you in another article.


Tuesday evening, I decided to treat myself to a raw meal at one of New York’s tastiest raw food restaurants and it was delicious. Within two hours, I started feeling burning sensations running through my head and I knew that the dish must have contained soy. This had happened to me before, when I was fasting in April. It was a different dish which I vowed never to eat a gain. I selected a new dish, last night, but failed  to inquire about soy.

Wednesday morning, I awoke with burning blood shot eyes and pain all over! Luckily, The Fig Tree products (herbs) were available to help me detox quickly. While this was a severe pain, I feel fortunate to have this awareness.  I have eaten fermented soy, when I was not cleansing and the affects were unnoticeable. I only avoided it due to its sodium content.

Ironically, I read about the health hazards of fermented soy, Tuesday morning. Nora Gedgaudas, CNS, CNT wrote, “Fermentation and fermentation only- largely neutralizes trypsin inhibitors and phytic acid. Goitrogens or thyroid inhibitors, however remain intact even following fermentation, so care must be taken not to overconsume even these soy foods.” – PRIMAL BODY PRIMAL MIND

The acid was neutralized? Not totally. That was definitely acid burning throughout my body last night and this morning. It is a fact that food acid is a top pain producer; I will follow-up with details in another article.  What if I had eaten some unfermented soy last night?

The first time I remember having soy, I had just moved to New York and could not cook for myself. I frequented a local Jamaican owned vegan spot. A week later, my face broke out and I had hard stools. Two weeks later, I came down with conjunctivitis. I asked a friend, “Why is this happening to me?”

After four weeks of eating tofu, a life-changing event occurred.  While I’m stopped at a traffic light in Harlem, a guy named Asa Ahla walks up to my car and hands me an essay titled, “Killing Our Families In The Name Of Love.” The essay covered the relationship between the pharmaceutical industry and crop seeds as well as genetically engineered foods.  His article was so compelling that I attended one of his lectures and eventually, heard about soy.


I love to research so I began my soy research journey there and, years later, I am still learning new ways in which it harms the body. Here is the breakdown of what I have learned:

1. Soy causes cancer. The term is “carcinogenic.”

2. Soy goitrogens (phytoestrogens) damage the thyroid leading to many issues, including hyperthyroidism.

3. Soy causes infertility.

4. Soy interferes with testosterone production and the development of the male reproductive system in infants.

5. Soy produces estrogen which causes premature development in female infants.

6. The high aluminum content in soy  is toxic to the nervous system and kidneys.

7. The neurotoxin,  monosodium glutamate (MSG), is produced during soy processing.

8. “The high levels of phytic acid in soy reduce the 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.” –Nora Gedgaudas, CNS, CNT

The list is much longer but I hope that I have provided enough for you to decide what is next for you. According to Nora Gedgaudas, it was deemed unfit for human consumption, since ancient times. Unfortunately, corporate interests used chemical processing to create a new product which they marketed as healthy. The process involved alkaline solutions, acid washing and high temperatures forming carcinogenic nitrates. To top it off, “natural flavoring” (MSG) is added.


You have to really inspect labels for words like bean curd, bean sprouts, dofu, edamame, kinako, kori-dofu, miso, natto, nimane, okara, shoyu, soy sauce, soya, soy bean (curds, granules), tamari, tempeh, tofu and yuba.

Ingredients created from soy; hydrolyzed soy protein (HSP), Mono- and di-glycerides, MSG, teriyaki sauce, texturized vegetable protein (TVP), Soy (albumin, cheese, fiber, grits, milk, nuts, sprouts, yogurt, ice cream, pasta)

If a product has these words, you will have to call the manufacture to find out if there is soy; bulking agent, hydrolyzed plant protein (HPP), vegetable protein (HVP), Gum Arabic, guar gum, lecithin, mixed tocopherols, natural flavoring, stabilizer, thickener, vegetable gum, starch, oil, shortening, vitamin E

Common foods with soy; Asian cuisine, baked goods, baking mixes, bouillon cubes, candy, cereal, chicken, chicken broth, chocolate, deli meats, energy bars, nutrition bars, imitation dairy products, vegan cheese, vegan ice cream, infant formula, margarine, mayonnaise, meat products with fillers ( ie, burgers or sausages), nutrition supplements, vitamins, peanut butter, peanut butter substitutes, protein powders, sauces, gravies, soups, smoothies, vegetable broth, veggie meats (boca burgers, imitation chicken,  imitation duck, imitation bacon, etc.) (Soy lists created by Jeanette Bradley About.com Guide)

I know this is a long list. The simplest solution is to avoid packaged products, when you don’t have time to read labels. I hope to provide more solutions for you, in the near future.

  1. Lots of people have problems with soy these days. Luckily, I’m not one of them, but it still sucks that it’s in so many things. I agree, it’s better to just avoid packaged food and eating out if you have sensitivities.

    Do you think the sensitivity is something that developed because we and our parents (while we were in utero) ate too much soy and animals that were raised on soy?

    Corn is in everything too. 🙁 Makes me concerned.

    • Hi Olivia,
      Thanks for reading:) You have an interesting point that I hadn’t considered. Intra-utero as well as hereditary transmission is a possibility. I assumed the reactions came from soy’s toxicity and indigestibility. Our bodies have protective mechanisms which alert us to problems…especially, if we keep our blood clean. So true about corn…sigh! I’ve eaten so called “GMO free” corn chips & sprouted corn tortillas but I can’t help wonder about them.

  2. Interesting post! I’ve read lots of bad and lots of good about soy products so I feel confused. In Esselstyn’s “My Beef with Meat” he has a chapter called “Don’t believe everything you read about soy” where he shares why soy is not harmful. I don’t eat a lot of soy, but I do consume it maybe once a week. Your post has made me think, however. Thanks for sharing! 🙂

    • Thanks Celeste:) I know that there’s a divide when it comes to soy. Since I wrote the post, I’ve been back and forth with people in forums about it. I learned a lot about how it has affected others.

      Some people become emotional and moody. My mom also told me that, after three years of eating soy, she began having black bumps. Some people reported constipation. Others said they wouldn’t touch it because 90% is GMO. I ended up learning enough to write another post..LOL!

      There are some books written about soy dangers.. Here’s a video link for a lecture by the author of one of them… http://www.youtube.com/watch?v=8Ij14ET-8Fg

      I always encourage people to test their bodies. I think it’s most important to pay attention to your digestion. (e.g. Are you eliminating as much as you eat?) If you are eating three meals with snacks in between then you should be having 4-5 good bowel movements.

      Then, if you decide to give it up, you’ll have to pay more attention to labels because it’s in so many packaged goods…

  3. These issues only seem relevant if you are on an intense diet? I have been a vegetarian since birth, 21 years now, and can eat everything. Is it because I’m a hungry male who is not a picky eater? There are so many positives of soy that I cannot imagine ever trying to cut down on it, most days I am trying to get more! Also it is extra relevant because I have been living in Thailand the past 6 months. Although my appetite has shrunk a bit due to smaller portions here, that seems to be the only impact that I have felt being here. ‘Food’ for thought

    • Wow, Thailand! That must be fun. Thanks for taking the time to visit:) I see your point. I was an omnivore and could eat every thing until I was 9. I gave up meat for Lent. After 40 days of not eating meat I got sick. It seems that when I let go of certain food items for a period of time and reintroduce them, that’s when my body shows me how harmful they are. The same thing happened with dairy products. I had “allergies” and didn’t know that meat and dairy were the cause until I gave them up.

  4. I understand havin g a soy sensitivity, perhaps allergy, as it appears you do and therefore refraining from soy. However, I am concerned about the fear you may be implanting in people by stating things such as soy causing cancer. Many, many things can cause cancer if not done in moderation. Furthermore you state that you have done a lot of research. The link you provided is to some random website. Do you have any published, peer-evaluated research to back up your claims? I truly would love to see them if you do, I just really don’t trust your sources because anyone can say anything they please on the internet to get attention or promote their vested interest. I would like to see some published journal articles and then I’ll get busy tossing all my soy. Till then, not convinced. <– especially since Asian countries have been using soy for centuries and historically have been some of the healthiest people.

    • Hi Isa:) So many people have come to me frustrated, because they have pain, an illness or reproductive issues and they think they are eating healthy. I suggest that they refrain from soy and it helps. I mostly wrote this post for people, like them, who have issues and think that they are eating the perfect diet. I want people to be aware of the possibility that it could be soy.

      I agree that many things can cause cancer, which is why it is challenging for anyone to conduct a proper study. I wish I had saved all of the information that I have read throughout the years but I had no idea that I would start a website and write, etc. Most, of what I read, were written by practitioners like me who had seen people suffer from soy. Besides the link, which directs to multiple links, one of my sources is a book and here is another book that you can read if you are truly interested: http://www.amazon.com/The-Hidden-Dangers-Dianne-Gregg/dp/1432717022

      From the perspective of Arnold Ehret, constipation is the cause of all illness and there are many foods that constipate the body; including the plastic-making soybean. The fact that most of the soy in the US is GMO and that the majority of the soy products are processed with chemicals like Hexane makes it highly carcinogenic. However, even if you are eating whole organic soy, you are still consuming uric (labelled as phytic) acid. Acid causes disease and pain.
