• Health Risks Of Soy

      By Dr. Joseph Mercola HuffPost Healthy Living

      Who hasn't heard of the marvels of soy? The marketing bandwagon has touted soy as the perfect health food for decades. But could something that sounds so healthful actually be dangerous?

      If you take the time to look into the actual science, then the answer is yes. Thousands of studies link soy to malnutrition, digestive distress, immune system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility -- even cancer and heart disease.

      One of the primary reasons it would be wise for you to avoid soy is that more than 90 percent of soybeans grown in the United States are genetically modified. Since the introduction of genetically engineered foods in 1996, we've had an upsurge in low birth weight babies, infertility, and other problems in the U.S., and animal studies have shown devastating effects from genetically engineered soy including allergies, sterility, birth defects, and offspring death rates up to five times higher than normal.

      Soybean crops are also heavily sprayed with chemical herbicides, such glyphosate, which a French team of researchers have found to be carcinogenic.

      Soybeans -- even organically grown soybeans -- naturally contain "antinutrients" such as saponins, soyatoxin, phytates, trypsin inhibitors, goitrogens and phytoestrogens. Traditional fermentation destroys these antinutrients, which allows your body to enjoy soy's nutritional benefits. However, most Westerners do not consume fermented soy, but rather unfermented soy, mostly in the form of soymilk, tofu, TVP, and soy infant formula.

      Unfermented soy has the following 10 adverse affects on your body:

      1. High Phytic Acid (Phytates): Reduces 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, but only with long fermentation. High-phytate diets have caused growth problems in children.

      2. Trypsin inhibitors: Interferes with protein digestion and may cause pancreatic disorders. In test animals, trypsin inhibitors in soy caused stunted growth.

      3. Goitrogens: Potent agents that block your synthesis of thyroid hormones and can cause hypothyroidism and thyroid cancer. In infants, consumption of soy formula has been linked with autoimmune thyroid disease. Goitrogens interfere with iodine metabolism.

      4. Phytoestrogens/Isoflavones: Plant compounds resembling human estrogen can block your normal estrogen and disrupt endocrine function, cause infertility, and increase your risk for breast cancer.

      5. Hemagglutinin: A clot-promoting substance that causes your red blood cells to clump, making them unable to properly absorb and distribute oxygen to your tissues.

      6. Synthetic Vitamin D: Soy foods increase your body's vitamin D requirement, which is why companies add synthetic vitamin D2 to soymilk (a toxic form of vitamin D).

      7. Vitamin B12: Soy contains a compound resembling vitamin B12 that cannot be used by your body, so soy foods can actually contribute to B12 deficiency, especially among vegans.

      8. Protein Denaturing: Fragile proteins are denatured during high temperature processing to make soy protein isolate and textured vegetable protein (TVP). Chemical processing of soy protein results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines.

      9. MSG: Free glutamic acid, or MSG, is a potent neurotoxin. MSG is formed during soy food processing, plus additional MSG is often added to mask soy's unpleasant taste.

      10. Aluminum and Manganese: Soy foods contain high levels of aluminum, which is toxic to your nervous system and kidneys, and manganese, which wreaks havoc on your baby's immature metabolic system.

      Soy's antinutrients are quite potent. Drinking just two glasses of soymilk daily provides enough of these compounds to alter a woman's menstrual cycle. But if you feed soy to your infant or child, these effects are magnified a thousand-fold. Infants fed soy formula may have up to 20,000 times more estrogen circulating through their bodies as those fed other formulas. You should NEVER feed your infant a soy-based formula!

      In fact, infants fed soy formula take in an estimated five birth control pills' worth of estrogen every day.

      As dangerous as unfermented soy is, fermented soy from organic soybeans is a different story altogether and can be a beneficial part of your diet. Fermented soy is a great source of vitamin K2, and K2 (combined with vitamin D) is essential in preventing osteoporosis, cardiovascular disease, dementia, and various types of cancer.

      Note that tofu is NOT on this list and is among the soy foods I do not recommend. Traditionally fermented soy products include:



      Soy sauce (as long as it's fermented in the traditional way, and not all are)
      Contrary to what you may have heard, Asians do not consume large amounts of soy. They use small amounts as a condiment (about two teaspoons daily), but not as a primary protein source. And the type of soy they consume is traditionally fermented soy.

        I am not familiar with the author of this article,
        But this article has no references or scientific citations supporting his conclusions or findings.
        According to him soy is not only not good for you, but downright poisonous. I've never heard of such absolute nonsense. Regardless he certainly has some really strong opinions on soy.
        Maybe soy stole his girlfriend and kicked his dog.

        Just because an article has or does not have references or scientific citations, does not mean it is legit or not. This is an article for the Huffington posts; ergo, there will be no citations.

        Also, if you do not know the evils of soy, then you have your heads in the ground. Soy is not good for you, despite what you cats think you no.

        No citation needed.

        I went soy crazy about 6mths ago. All I used for my protein, minerals and vitamins was anything soy I could get my hands on. I wanted to truly find out if soy was bad or good
        so I stopped all meat, dairy, etc.. anything that would interfere with results and got
        all my protein from soy alone. I used tons of Edamame, Soy nuts, Soy milk, Soy Isolate Powder, Soy meat, etc.. I felt better than ever but I couldn't gain muscle..lost over 20lbs, was down 179lbs so I gave it up.. now back to my regular diet I'm back to 195-202lbs in less than few mth's. Soy made me feel the best ever and weight loss was simple but that's
        not what i wanted...but all in all I'd say it does block nutrients or something from being absorbed ..its too bad... Edamame was the bomb!

        I still don't get why anyone eats or drinks that crap. Seriously. I do not care if all these points are correct or not. Soy will never be part of my diet. There is no use for it for a grown man or a woman. Unfortunately, everyone tries to slip this garbage into all products made outside of my kitchen to bump up the 'protein' content or preserve moisture. It is abused as much as freaking corn!

        You should diversify your protein sources and soy is by no means NEEDED in one's diet. It appears to not be as good for MPS as some sources like whey, casein, chicken, etc. Nonetheless, it is a cheap and relatively carb/fat free source of protein that you can utilize in your diet. With whey and food in general skyrocketing in price, don't rule out every soy containing product that you see. There are no legitimate health risks. A study was performed on grown men and there were no changes in sex hormones when the men's ENTIRE protein source was soy vs not soy.

        One day siting in one of my courses at school. A women gave her speech on the benefits of breast feeding and then went on to discuss formula. She said that they do not recommend giving boys soy formula for the reason of estrogen. That was a shock to me because she wasn't trying to sell me protein powder. She was talking about an infant boys health
