I have been trying to address the numerous bogus soy claims from this post. But it is so long and twice I have lost my writings before I could address all the false claims so I am going to break these up and address them in smaller groups, which will also make reading a lot easier.
Myth: Asians consume large amounts of soy foods.
Truth: Average consumption of soy foods in Japan and China is 10 grams (about 2 teaspoons) per day. Asians consume soy foods in small amounts as a condiment, and not as a replacement for animal foods.
The real truth: Where did this bogus propganda come from? Well it is psoted on page 3 of this link from some whacko site called "Vegetarians are Evil"
The fact is that soy is a major component of the Asian diet in a numer of products such as tofu, miso, edamame, etc.
Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods.
Truth: Most modern soy foods are not fermented to neutralize toxins in soybeans, and are processed in a way that denatures proteins and increases levels of carcinogens.
The real truth: Cooking denatures proteins and leads to carcinogen formation. I wonder how many of these soy bashers cook their meat before eating it? In addition many soy products are fermented including tofu, natto and miso, so they are being misleading.
Myth: Soy foods provide complete protein.
Truth: Like all legumes, soy beans are deficient in sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine.
The real truth: I addressed this myth here:

And if they bothered to check the amino acid profile of soybeans they would find that soy does in fact contain methionine and cystine:
http://en.wikipedia.org/wiki/Soybean
And regardless of what the amino acid profile is we must also keep in mind that our body generates some of its own amino acids, and we also obtain other amino acids from other dietary sources. If we consumed the same thing all the time like only beef or only milk we would develop deficiencies. This is why we eat a varied diet. So again they are attempting to mislead people.
Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets.
Truth: The compound that resembles vitamin B12 in soy cannot be used by the human body; in fact, soy foods cause the body to require more B12
The real truth: Plants generally do not contain active B12, but rather B12 analogues. So if they are going to claim this about soy then they will also have to make this claim about most plants we eat. Although there is NO evidence that B12 analogues increase our need for Active B12, and they fail to take in to account the fact that plant fibers feed the flora, which generate active B12. So again they are attempting to mislead people.
Myth: Soy formula is safe for infants.
Truth: Soy foods contain trypsin inhibitors that inhibit protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted growth and pancreatic disorders.
The real truth: Notice they mentioned "test animals", which indicates non-human studies. Well guess what? They must also believe then that chocolate is deadly since it will kill a dog. We are not the same as dogs, cats, mice rabbits, etc. To say based on an animal study that something is toxic is ludicrous. In addition many studies overload the animal to make something appear toxic when it is not at normal levels. For example the study that claimed chromium picolinate could cause cancer because it caused neoplasms in mice given a dose 6,000 times the equivalent level that would be given to a human.
In addition they failed to mention the well known fact that trypsin inhibitors are destroyed by fermentation or cooking used in the preparation of soy showing a DELIBERATE intent to mislead the public.
Soy foods increase the body’s requirement for vitamin D, needed for strong bones and normal growth.
There is no evidence that soy increases the need for vitamin D either. This is nothing but a persistent perpetuated myth. Soy is low in vitamin D so soy products are frequently fortified just like cow's milk:
http://www.health.state.ny.us/diseases/conditions/osteoporosis/vitd.htm
They also fail to mention that plants do not contain active vitamin D anyway, which is why our body produces active vitamin D from cholesterol and inactive D2. So again they were misleading the public.
Phytic acid in soy foods results in reduced bioavailabilty of iron and zinc which are required for the health and development of the brain and nervous system.
I addressed this misleading claim a number of times:
http://curezone.com/forums/fm.asp?i=1542754#i
Soy also lacks cholesterol, likewise essential for the development of the brain and nervous system.
The real truth: Another desperate means to badmouth soy. Do they recommend not drinking water because it lacks cholesterol? And if they knew ANYTHING about how the body works then they would have known that the liver synthesizes the cholesterol the body needs. We do not require food sources of cholesterol.
Megadoses of phytoestrogens in soy formula have been implicated in the current trend toward increasingly premature sexua| development in girls and delayed or retarded sexua| development in boys.
The truth is again this claim lacks evidence. Soy only contains a very small percentage of phytoestrogens by weight, which are actually decreased during the cooking or fermentation of processing. Furthermore, phytoestrogens average 200 to 400 times weaker than the body's own estrogens. So a person would have to consume probably at least 10 pounds of soy in one sitting to get the same amount of estrogen in a glass of milk or a steak., which contain estrogens even stronger than human estrogens.
The link between dietary estrogens and early development of children has been examined for long time. But the link was found to be from the estrogens in meats, not soy. I ran several searches and could not find even one study linking soy to early development, Current research is also pointing to environmental xenoestrogens, which can be 30,000 to 100,000 times stronger than human estrogens. These include the xenoestrogens in plastics and shampoos to name a few.
And I addressed this earlier:
