The Whole Soy Story

After a visit to a homeopathic doctor in 2008, I discovered that I am soy intolerant, a diagnosis that has changed my life in many ways.*  I used to be a sushi addict and my mouth still waters at the idea of a spicy tuna roll dipped in soy sauce, but then I remember the days following my sushi binges and how the soy sauce would leave me curled in the fetal position on the floor of my bathroom, writhing around in pain. 

I also was a vegetarian for nearly ten years prior to this diagnosis.  I lived off of tofu burgers and veggies shreds.  As soon as I learned that the soy was making me sick, I had to completely change my lifestyle and begin eating meat again.

A few months prior to my diagnosis, it was also discovered that my older son, Gabriel, had a soy allergy.  His first bottle of soy-based formula caused a severe allergic reaction.

Because of this our home has been soy-free for nearly two years, except for a couple of foods that my husband enjoys to have around as snacks.  Gabriel and I are also unable to eat food that has been prepared at restaurants, because the only items on the majority of menus that do not contain a soy product are plain fruits and veggies that haven't touched the grill (which is usually covered in either margarine or soybean oil).

It is estimated that nearly 70% of the foods on our supermarket shelves contain soy.  It has become filler that is used in just about everything, because it is cheap.  But what's even worse is that over 60% of the soybean crop in the United States is genetically modified.

One day Adam heard a news story that linked soy to hormone imbalances in men, specifically that eating high levels of soy causes men to produce more estrogen, leading to a whole host of health problems.  That was the final straw - all of the negative information I had been hearing about soy made me want to learn more about why it is considered a "healthy" food in our culture.

I finished reading The Whole Soy Story by Kaayla T. Daniel, PhD, CCN and I learned more than I ever wanted to know about the food.  The book gives a background on how this crop that historically was used as a cover crop to enrich soil, became part of a health-food craze in America. It also breaks down all of the health concerns about eating soy.  I recommend the book for anyone interested in learning why you shouldn't be consuming this food in the amounts that we find in the average American's diet.

I just wanted to highlight some of the interesting things I learned while reading the book:

The study that really made soy a healthy food in America showed that the Japanese (who eat 30 times the soy we eat) have lower rates of breast, uterine and prostate cancer.  What the media coverage of this study failed to also tell us is that the Japanese have higher rates of esophageal, stomach, pancreatic and liver cancers.  Asians also do not eat soy in the ways we eat it.  They leave the soybean intact in fermented products like miso, tempeh and natto. 


The FDA approves soy protein as a heart healthy food but it is also found on their "Poisonous Plant Database."


Soybean oil is a mosquito repellant.  It actually kills the mosquito, which makes you wonder what it does to your insides.


People who eat ground meat with textured soy protein extenders (this is what is served to our children in school) lose 61% (at a 3:1 ratio) and 53% (at a 2:1 ratio) of their ability to absorb the iron from the meat.


Here are all of the toxins and antinutrients that soy contains: 

• allergens
• goitrogens - cause thyroid damage
• lectins - cause immune system reactions and play a role in allergic reactions because they destroy intestinal mucosa.
• oligosaccharides - cause bloating and gas
• oxalates - prevent the absorption of calcium and linked to kidney stones
• phytates - leads to poor growth and anemia.  Levels are higher in soy than in any other food.
• isoflavones - cause reproductive damage
• protease inhibitors - cause gastric distress, poor protein digestion, cancer, and damage to the pancreas.  Many foods contain them (grains, nuts, seeds, some veggies, etc.), but cooking deactivates them.  They are at higher levels in soybeans (and even higher in GM beans) and are more resistant to neutralization through cooking.

The scariest information to read was about soy-based formula:

• The isoflavones in the formula effect hormones and can cause developmental problems in the reproductive system.  They also put children at an increased risk of thyroid problems (hypothyroidism and autoimmune thyroid disease). 
• Infants fed soy formula also produce more gas (CH4 and H2S), which has been linked to intestinal disorders, such as ulcerative colitis and Crohn's Disease. 
• Scientists have suggested expensive techniques that would neutralize the phytates in formula, but the industry prefers to go the cheaper route and enrich the formula with zinc, iron and calcium to compensate.  They are required by law to do this. 
• Iron absorption from soy formula is 27%.  It is 65% in breast milk, 60% in whey formula and 46% in casein formula.

Something I learned from the author's website - "The Israeli Health Ministry has issued a health advisory warning that infants should not use soy formula. So have the British Dietetic Association, the New Zealand Health Ministry, and the Swiss Federal Health Service."

Soy lectin may contribute to Type 1 Juvenile Onset Diabetes because it destroys pancreatic cells that secrete insulin.

Asian monks used to eat high levels of soy because it was known to lower their libido.

I have also read before that animals that are fed diets high in soy fail to thrive and show signs of malnutrition.  They also have a shorter lifespan and produce less offspring. 

When I put all of this information together, it's a no-brainer for me.  It's yet another reason to make sure the food I am feeding my family isn't processed and is prepared properly (soaked, cooked properly, etc.).  Since cutting out soy from my diet, I have not had a major flare-up of my Crohn's Disease and have been able to stay off of toxic drugs like Prednisone.  I think I now know why!

If you are interested in learning more about soybeans, I suggest reading this book!

I was not contacted by anyone to review this book.  I just enjoyed it and wanted to share some information with my readers.
