For centuries, Asian people have been consuming fermented soy products such as natto, tempeh, and soy sauce, and enjoying the health benefits. Fermented soy does not wreak havoc on your body like unfermented soy products do.

Unfortunately, many Americans who are committed to healthy lifestyles have been hoodwinked and manipulated into believing that unfermented and processed soy products like soymilk, soy cheese, soy burgers and soy ice cream are good for them.

How Did Soy Foods Become So Popular?

If it seems like soy foods appeared out of nowhere to be regarded as the “miracle health food” of the 21st Century, it’s because they did.

From 1992 to 2006, soy food sales increased from $300 million to nearly $4 billion, practically overnight, according to the Soyfoods Association of North America. This growth came about due to a massive shift in attitudes about soy. And this shift was no accident—it was the result of a massive investment in advertising by the soy industry that’s been wildly successful.

From 2000 to 2007, U.S. food manufacturers introduced more than 2,700 new soy-based foods, and new soy products continue to appear on your grocer’s shelves.

According to the survey Consumer Attitudes About Nutrition 2008 (by the United Soybean Board):

  • -As of 2007, 85 percent of consumers perceive soy products as healthful
  • -33 percent of Americans eat soy foods or beverages at least once a month
  • -70 percent of consumers believe soybean oil is good for them
  • -84 percent of consumers agree with the FDA’s claim that consuming 25 grams of soy protein daily reduces your risk of heart disease

This is a tragic case of shrewd marketing and outright lies taking root among the masses with the end result of producing large profits for the soy industry and impaired health for most who have been deceived into using unfermented soy long-term..

As you can see from the extensive list of articles below, there is a large amount of scientific research showing that soy is not the nutritional panacea of the 21st Century.

The Dark Side of Soy

The vast majority of soy at your local market is not a health food. The exception is fermented soy, which I’ll explain more about later and even worse GMO soy that is contaminated with large pesticide residues as the reason it is GMO is so they can spray the potent toxic herbicide Roundup on them to improve crop production by killing the weeds.

Unlike the Asian culture, where people eat small amounts of whole non-GMO soybean products, western food processors separate the soybean into two golden commodities—protein and oil. And there is nothing natural or safe about these products.

Dr. Kaayla Daniel, author of The Whole Soy Story, points out thousands of studies linking soy to malnutrition, digestive distress, immune-system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility—even cancer and heart disease.

Here is just a sampling of the health effects that have been linked to soy consumption:

Soy proponents will argue that soy-based foods (they lump the fermented ones with the unfermented) will protect you from everything from colon, prostate and breast cancer to strokes, osteoporosis, and asthma.

But said enthusiasts never mention the studies that illuminate soy’s downside and all of the dangers posed to your health, which are based on sound research.

Another unfortunate fact is that 80 percent of the world’s soy is used in farm animal feed, which is why soy production is contributing to deforestation. Some soy propagandists have suggested that the solution to this is for all of us to become vegetarians—a reckless recommendation rooted in total ignorance about nutrition—whereas a far better solution is a major overhaul in how farm animals are fed and raised.

What Makes Soy Such a Risky Food to Eat?

Here is a summary of soy’s most glaring problems.

  1. 91 percent of soy grown in the US is genetically modified (GM). The genetic modification is done to impart resistance to the toxic herbicide Roundup. While this is meant to increase farming efficiency and provide you with less expensive soy, the downside is that your soy is loaded with this toxic pesticide. The plants also contain genes from bacteria that produce a protein that has never been part of the human food supply. GM soy has been linked to an increase in allergies. Disturbingly, the only published human feeding study on GM foods ever conducted verified that the gene inserted into GM soy transfers into the DNA of our gut bacteria and continues to function. This means that years after you stop eating GM soy, you may still have a potentially allergenic protein continuously being produced in your intestines.Even more frightening is the potential for GM soy to cause infertility in future generations, which has been evidenced by recent Russian research.
  2. Soy contains natural toxins known as “anti-nutrients. “Soy foods contain anti-nutritional factors such as saponins, soyatoxin, phytates, protease inhibitors, oxalates, goitrogens and estrogens. Some of these factors interfere with the enzymes you need to digest protein. While a small amount of anti-nutrients would not likely cause a problem, the amount of soy that many Americans are now eating is extremely high.
  3. Soy contains hemagglutinin. Hemagglutinin is a clot-promoting substance that causes your red blood cells to clump together. These clumped cells are unable to properly absorb and distribute oxygen to your tissues.
  4. Soy contains goitrogens Goitrogens are substances that block the synthesis of thyroid hormones and interfere with iodine metabolism, thereby interfering with your thyroid function.
  5. Soy contains phytates. Phytates (phytic acid) bind to metal ions, preventing the absorption of certain minerals, including calcium, magnesium, iron, and zinc — all of which are co-factors for optimal biochemistry in your body. This is particularly problematic for vegetarians, because eating meat reduces the mineral-blocking effects of these phytates (so it is helpful—if you do eat soy—to also eat meat).
  6. Soy is loaded with the isoflavones genistein and daidzein Isoflavones are a type of phytoestrogen, which is a plant compound resembling human estrogen. These compounds mimic and sometimes block the hormone estrogen, and have been found to have adverse effects on various human tissues. Soy phytoestrogens are known to disrupt endocrine function, may cause infertility, and may promote breast cancer in women.Drinking even two glasses of soymilk daily for one month provides enough of these compounds to alter your menstrual cycle. Although the FDA regulates estrogen-containing products, no warnings exist on soy.
  7. Soy has toxic levels of aluminum and manganeseSoybeans are processed (by acid washing) in aluminum tanks, which can leach high levels of aluminum into the final soy product. Soy formula has up to 80 times higher manganese than is found in human breast milk.
  8. Soy infant formula puts your baby’s health at risk.Nearly 20 percent of U.S. infants are now fed soy formula, but the estrogens in soy can irreversibly harm your baby’s sexual development and reproductive health. Infants fed soy formula take in an estimated five birth control pills’ worth of estrogen every day.Infants fed soy formula have up to 20,000 times the amount of estrogen in circulation as those fed other formulas!

There is also the issue of pesticides and genetic modification.

Soy foods are both heavily sprayed with pesticides and genetically modified (GM). More than 80 percent of the soy grown in the United States is GM. And more than 90 percent of American soy crops are GM.

Since the introduction of GM foods in 1996, we’ve had an upsurge in low birth weight babies, infertility, and other problems in the U.S. population, and animal studies thus far have shown devastating effects from consuming GM soy.

You may want to steer clear of soy products for no other reason than a commitment to avoiding GM foods… unless you wish to be a lab animal for this massive uncontrolled experiment by the biotech industry.

What Soy Products are Good For You?

Soy can be incredibly healthful, but ONLY if it is organic and properly fermented.

After a long fermentation process, the phytate and “anti-nutrient” levels of soybeans are reduced, and their beneficial properties become available to your digestive system.

You may have heard that Japanese people live longer and have lower rates of cancer than Americans because they eat so much soy—but it’s primarily fermented soy that they consume, and it’s always been that way.

Fermented soy products are the only ones I recommend consuming.

These are the primary fermented soy products you’ll find:

-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.
