Soy is not as dangerous as is being touted. Somewhere along the line someone started a bunch of false rumors about soy, that have been repeated over and over by people who have failed to research the facts before continuing the rumors. I truly believe that these rumors were likely started by either the beef or dairy industry since they are the most adversely effected financially by the increased popularity of soy.
Here is an article I wrote on the subject previously:
Soy fact and Fiction
There are various sites on the Internet spewing false and misleading information about soy. The information is so convincing that even naturopathic doctors are repeating the falsehoods rather than verifying whether or not the information is valid. I had this problem with a naturopathic doctor on the Yahoo boards. He finally kicked me off his board because I was posting proof that his false claims about soy were in fact false. So instead of admitting he was wrong, he called me a quack, kicked me off his board, then told people not to talk to me through e-mails.
Here are some of the common myths about soy:
Fiction: Soy causes cancer.
Fact: Phytoestrogens are plant based estrogenic substances. On average phytoestrogens are about 200 to 400 times weaker than the body’s own estrogen. So they have a duel effect by both acting as very weak estrogens and by locking up estrogen receptors to block the action of stronger and more dangerous estrogens. For instance Premarin (PREgnant MARes urINe), which is 3,000 times stronger than human estrogen, and xenoestrogens, such as dioxin and PCBs, which can be as high as 30,000 times stronger than human estrogens. Many phytoestrogens can be derived from diet. Dietary sources include soy, sage, yams, parsley, peas, kudzu, and seaweeds. Other sources include red clover, licorice root, and numerous other herbs. In fact phytoestrogens have been isolated from over 350 different plants.
Flavonoids, found in various foods, especially berries also function in the same manner as phytoestrogens.
Fiction: Soy causes hypothyroidism.
Fact: Soy does contain goitergens, as do broccoli, peanuts, and various other foods. Though goitergens are readily destroyed by fermentation, or as little as 10 minutes of cooking. Soy products, including soy milk, are either cooked or fermented.
Fiction: Soy stunts growth, and the high consumption is why Orientals are so short. I actually heard this from another naturopathic doctor.
Fact: Height is dependent on genetics, and soy does not stunt growth. In fact I was allergic to both mother's milk and cow's milk as an infant, and was raised on soy milk. I am 6' 2", the same height as my father.
Fiction: Because of the estrogens in soy, consuming soy makes people gay. Another one I actually read on posts on the net.
Fact: Again this has genetic factors, and has nothing to do with soy consumption. By the way, I am not gay either.
Fiction: Soy is high in aluminum because they wash the soybeans in aluminum vats with sulfuric acid.
Fact: I really got a kick out of reading this one. If anyone has ever really worked with sulfuric acid, then they know how nasty this acid can be!!! The acid is very hygroscopic and likes to turn organic materials, such as skin, in to carbon by stripping hydrogen and oxygen from the material to form water, leaving behind the carbon. If the soybeans were washed in sulfuric acid you would not have soybeans, you would have carbon balls.
Secondly the acid would eat away the aluminum of the vats creating very dangerous amounts of free hydrogen gas. Not to mention the fact that they would have to be constantly replacing the vats that are being eaten away, which would be prohibitively costly in both replacement costs and downtime.
I am leery of GMO as well. There have already been incidences of death from GMO products. Starlight corn had a peanut gene spliced in to it. Peanuts are one of the most common allergens and can cause deadly anaphylaxis. And this is exactly what happened.
Another problem is that bees can carry the pollen from GMO plants in to non-GMO farms cross pollinating other crops with these dangerous genes.
Luckily, non-GMO soy is available. And if people start refusing to buy GMO crops then there will be no incentive for the production of GMO crops.
I have written on this subject quite a few times. Here is one of my write ups:
Phytoestrogens DO NOT promote cancer. Phytoestrogens are on average 200 to 400 times weaker than the body's own estrogens. They can lock up estrogen receptors though blocking the actions of stronger estrogens. This is why many studies have found anti-cancer properties to soy and other phytoestrogen sources. In fact many phytoestrogens and phytoestrogens are routinely used to fight cancer. Red clover blossoms for example, which contains the same phytoestrogens found in soy plus two others. And resveratrol from grape skins, which is also a phytoestrogen.
And what about broccoli and other cruciferous vegetables, which are also phytoestrogen sources. And seaweeds that have a long history of being used in the treatment of cancer.
Many of the common foods we eat, and that are considered healthy, are actually phytoestrogen sources. These include sage, parsley, yams, peas, kudzu, beans, peanuts, seaweeds, carrots, bananas, oranges, millet, corn, barley, grapes, berries, baker's yeast, beets, pomegranates, cherries, garlic, oats, olives, peppers, wheat, sunflower seeds, flax seed, rye, spinach, sesame seeds, pumpkin seeds, quinoa, rhubarb, tomatoes, rice, plums, potatoes, papaya, dates, eggplant, cabbage, broccoli, cauliflower, anise, fennel, cucumber, peanuts, and onions.
And there are beverages people think are healthy, at least in moderation. These include green tea, grape juice, and wines. Beer, ouzo, gin, and whiskey are also very high in phytoestrogens.
Then there are flavonoids, which also have phytoestrogen-like effects. These are also found in many foods including berries and onions.
Bottom line is that if people really want to avoid phytoestrogens they will pretty much need to stop eating and drinking.
Luckily phytoestrogens provide numerous health benefits including protecting us from cancer and improving bone strength.
As a side note, anyone remember the "Grape Cancer Cure"? The only thing I can see in grapes that would allow them to be highly effective against cancer are the phytoestrogens in the grapes.
As for soy and its phytoestrogens, I think this myth of phytoestrogens promoting cancer just keep getting spread around by anti-soy proponents to scare people away from soy. I have seen so many myths about soy being posted on message boards and have even received them in my e-mails.
Why do you keep posting propaganda websites as "evidence"? These are not evidence of anything.
Do you realize how many common, healthy foods we consume on a daily basis that are higher in phytoestrogens than soy? Yams, flax seed, seaweeds, peas.......
And she mentioned evening primrose oil, which can definitely play havoc on the hormones. But she is going to ignore all these facts and blame soy all because she also read some phony propaganda site.
And think about the herbs used to TREAT cancer. Do you know how many of them are phytoestrogen sources. Red clover blossom for example contains the same exact phytoestrogens as soy, PLUS two others. Yet, I don't see any of these propaganda sites warning against red lover blossom. Or flax, or broccoli, or seaweeds, garlic, onions, cloves, cilantro, turmeric.....
This is why propaganda sites are worthless as evidence. They twist information to fit their viewpoint. Just like the videos you posted about amalgams. I love how they took a fresh amalgam in a glass jar sealed tight so no mercury vapor could escape then used a sniffer to show how much mercury there was. Well DUH!!! They must think the general public is pretty stupid! Well I guess some people are because they are falling for it.
As for as the thyroid goes, again they are being VERY misleading. Goitergens are inactivated by cooking or fermentation. Again, soy products are fermented or cooked. When was the last time you have seen someone eat raw unfermented soybeans?
