Sorry Soy

Soy is one of those deceptive foods like sugar that is not likely to be harmful in small amounts but will contribute to a variety of health problems when consumed in excess over time. Traditionally, soy has been eaten in small amounts and only in fermented form in Asia for many hundreds and possibly a few thousand years. In small amounts, fermented soy does not appear to be detrimental to health. The modern problem is that most soy in foods today is not properly fermented and is added in abundance to so many foods that it is easy to get too much. It is also processed in ways that create additional hazardous chemicals that end up in soy products.

Proponents of soy tout it as a "health food" and laud the high protein and isoflavane content. But most of this propaganda is coming from those who are selling soy for a profit. A closer look reveals that yes, soy is high in protein and nutrients, but these nutrients are not very bioavailable because of the abundant enzyme inhibitors and anti-nutrients that are also in soy. Soy contains trypsin inhibitors and haemagglutinin which are growth inhibitors, isoflavones that are both goitrogens and phytoestrogens which interfere with the endrocrine system, and phytic acid which binds to minerals to make them undigestible. These compounds are found in other legumes and grains, but soy has much higher concentrations and that's bad news for health.

Cooking helps to slightly reduce some of the detrimental compounds, but fermentation is required to achieve the greatest reductions. Even fermentation does not eliminate them and that is why fermented soy should only be consumed in small amounts.

Long-term excess consumption of soy increases risk of thyroid problems, reduces male fertility, causes premature female sexual development, and increases risk of endrocrine related cancers including breast cancer and prostate cancer. These problems are seen not only in humans, but also in animal models.

As if these problems are not enough, also consider that most soy is now genetically modified to withstand massive amounts of toxic herbicide, which can also contaminate the soy products. Yet another reason to avoid soy!

Wow. I have been telling people this for the last year, and all I ever received were funny looks or remarks about how they were told soy was 'healthy.' Like you said 'But most of this propaganda is coming from those who are selling soy for a profit.'

I found an excellent article, 'Dangers of Soy', from the website themostimportantwebsite.com.

Thanks for this information.

I know what you mean by funny looks. People have been mislead by the cascade of misinformation about soy for so many years now that they find it hard to believe soy is bad. I run into the same problem trying to convince people that cholesterol and saturated fat are good and polyunsaturated fat is bad. It's like trying to convince people in the middle ages that the world is round and not flat or that the sun is not the center of the universe :)

The Dangers of Soy article was published in 2000 by the same authors Sally Fallon and Mary Enig who published "Soy: the Dark Side..." in 2004, which I referenced under "Further Reading".

I'm afraid it's still a steep uphill challenge to enlighten the masses about soy. Keep spreading the word. Every little bit helps.

Herry, it's true that one person's food can be another person's poison. In the case of soy, it certainly won't kill you right away, but does not appear to be a good food for optimal health in large quantities, especially over many years.

There are plenty of good traditional foods that won't cause health problems. Even in the legume family, most other beans and lentils are much better tolerated for most people.

Yes there is a danger when it comes to soy? let me just clarify this "I mean Soy Sauce" :) instead of using soy beans for creating soy sauce they use this janitor fish. I can't believe it they did that. I was very controversial because it's in the news all over the country...
