A client asked me the other day,”Marc, what do you think of Soy” I sometimes have to think carefully about how I answer certain questions – I sometimes can come off a bit to harsh – I said, “I don’t think much of Soy, in fact I think most of it’s toxic, causes man boobs, thyroid inhibiting, increases estrogen – and for men, this can be especially problematic” and then there was a moment of awkward silence.

So let’s explore…..

For the scientists:
288 references to the toxicity of soy in the FDA’s poisonous plants database

77 studies showing the adverse reactions to dietary soy

174 studies showing the adverse reactions to isoflavones (phytoestrogens)

So, Is Soy Bad For You?
The short answer? YES! Let’s be clear on the recent history of soy. The soybean was a modest and unpopular crop until food manufacturers intent on creating cheap vegetable oils convinced the U.S. government to start subsidizing it. The soy was turned into oil, and the industry was left with an industrial waste product.

Then somebody had a brilliant idea:

Let’s take this industrial waste product full of toxins and carcinogens — isolated soy protein — add it to virtually almost every pre packaged food and turn it into food that people will eat!

From Nina Planck’s article:
The FDA refused to approve isolated soy protein as a safe food additive with the designation “Generally Recognized as Safe.”
Agribusiness giant Archer Daniels Midland withdrew its application for the coveted GRAS status for soy protein, after an outcry from scientists about the toxins and carcinogens that come with it. They can still put soy protein in your food, but they have to get pre-market approval for every product.

Isolated soy protein is no health food. But we don’t eat soy protein with a spoon. How do we eat it? It is the main ingredient in soy burgers, ice cream, milk shakes, and fake cheese. These soy protein products are phony foods — but they must look like the real foods they imitate. So the soy industry transforms a small yellow soy bean into something resembling a hamburger. They make soy “milk” and “ice cream” white and creamy.

The other ingredients in these foods are no better for you than the soy protein that goes into them. Soy milk, for example, is simply a cocktail of soy protein, sugar, and vegetable oil. The “natural” MSG formed in soy processing is already bad for you, but even more MSG, and more flavorings, are added. Imitation foods need a lot of help to be tasty. Many savory soy foods are loaded with additives to give them the flavor of the real foods they mimic. Most imitation meat, for example, contains man-made MSG, which causes migraines and is associated with brain cancer.

Soy foods aren’t real food. They aren’t traditional. They aren’t old. They’re industrial waste products dressed up in pretty clothes and marketed to an ignorant public.

Dangers of Soy

Kristen from The food renegade blog did a nice job describing some of the probelms associated with soy……so let’s take a peek!

Phytoestrogens
Soy is higher in phytoestrogens than just about any other food source. Phytoestrogens are plant-based estrogens that mimic estrogen in our bodies. In recent years, you may have read about studies which indicate phytoestrogens are good for you. But ask yourself, who funded those studies? The soy industry, that’s who. Independent research has clearly shown that consuming phytoestrogens is downright dangerous for the human body.

It’s only common sense. No one argues, for example, that a leading cause of breast cancer, endometriosis, uterine fibroids, infertility, and low libido is unopposed estrogen, or estrogen dominance. Why, then, would anyone argue that we should consume more of a food high in estrogen?

An infant taking the recommended amount of soy formula is consuming a hormone load equivalent of 4 birth control pills a day! Is it any wonder we’ve seen such a dramatic rise in precocious puberty with young girls starting their periods at 6 and 7?

Goitrogenic
Soy will destroy your thyroid. Many foods are goitrogenic (thyroid suppressing), but soy is king of them all. Goitrogens work by preventing your thyroid from getting the necessary amount of iodine. Friends, I believe this is what happened to Oprah’s thyroid. She pushed soy for years, featured it in everyone one of her “healthy” diets, and it destroyed her thyroid. If your thyroid fails, what happens? You gain weight. You have a harder time regulating your moods. You get colder more easily. You’re more easily fatigued. You demonstrate an inability to concentrate and remember details. The list goes on. You simply don’t want to mess with your thyroid.

Phytates
Phytates are enzyme-inhibitors that block mineral absorption in human digestive tract. They are naturally present in all grains, seeds, nuts, and legumes (which is why everyone should soak grains before eating – visit westonaprice.org for more info)- But soy is so high in phytates that it’s almost impossible to get rid of them. Simply soaking soy overnight in an acidic medium won’t do the trick. Soy must be fermented in order to be digestible to humans. That means that if you eat soy at all, you should stick to fermented soy products like miso, tempeh, natto, or a naturally fermented soy sauce (tamari).

Trypsin inhibitors
Finally soy is rich in trypsin inhibitors. Trypsin is a digestive enzyme we need to properly digest protein. Without enough trypsin, you’ll experience many digestive problems including stomach cramps, diarrhea, and bleeding. You’ll also be leaving yourself open to future problems with your pancreas.

Debunking The Asian Soy Myth

But, people say, what about Asians? They eat soy every day, and they’re so healthy!

Soy farming started around 1100 BC in China, where it was used to build soil fertility and feed animals. Soy beans were not considered fit for humans until the Chinese learned to ferment them, which makes them digestible. Asian diets now include fermented soy beans in the form of natto, miso, tamari, and tempeh.
Soy producers want you to eat more soy — more than the Asians eat, and more than is good for you.

The Japanese and Chinese eat 10 grams of soy per day — about two teaspoons. Yet a soy manufacturer recommends Americans eat ten times what the Japanese eat — 100 grams of soy protein per day. In The Soy Zone, Barry Sears recommends a daily diet of a minimum of 50 grams of soy, and up to 75 grams for women and 100 grams for men.
It’s like red wine: a glass or two a day may be good for you; a bottle or two every day rots your liver.

Did you catch that? Asians only eat 2 teaspoons of soy a day, usually as a condiment, and it’s highly fermented! Fermentation takes care of SOME of the dangers of soy. Plus, the typical Asian will also consume soy with mineral-rich and nutrient-dense foods such as fish broth (naturally high in iodine & other minerals which support the thyroid).

The Plano Program will continue to avoid all forms of soy whenever possible. Remember, most protein bars contain soy protein isolates as the main protein source. This is a cheap form of protein that is poorly utilized by the human body.
