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:
http://curezone.com/forums/fm.asp?i=1498735#i
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 B12The 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:

This is a reply to # 1,548,646
Myth: Soy foods can prevent osteoporosis.
Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths and vitamin D from seafood, lard and organ meats prevent osteoporosis in Asian countries—not soy foods.The real truth is: As I pointed out in my last post there are no studies showing that soy reduces vitamin D levels. And many soy products are being fortified with vitamin D, so they are being very misleading. As for calcium I have yet to see any evidence that soy reduces calcium either. In fact soy provides some calcium and magnesium. But more importantly is also provides other nutrients and compounds for healty bones. Particularly silica, which is the number one most important needed for healthy bones. Like vitamin D, silica helps with calcium absorption. Although unlike vitamin D silica helps to form the collagen matrix that is responsible the vast majority of bone's strength. In addition the silica is responsible for the mineralization of all bone, and this includes the mineralization by calcium. Without silica all the vitamin D and calcium is not going to do squat for the bones.
In addition, soy contains isoflavones that have been proven to INCREASE bone density and strength and/or decrease bone loss:
http://www.ncbi.nlm.nih.gov/pubmed/19877511?itool=EntrezSystem2.PEntrez.Pubme...
http://www.ncbi.nlm.nih.gov/pubmed/17392695?ordinalpos=1&itool=EntrezSyst...
http://www.ncbi.nlm.nih.gov/pubmed/18063230?ordinalpos=1&itool=EntrezSyst...
http://www.ncbi.nlm.nih.gov/pubmed/19759166?itool=EntrezSystem2.PEntrez.Pubme...
On the other hand meat and dairy have been shown to decrease bone density. This is in large part due to the high phosphorus content, which displaces calcium from bones. In addition high protein such as in dairy products interferes with calcium absorption. This is why the highest milk consuming nations in the world also have the highest osteoporosis rates.
In addition animal proteins have been shown to induce bone loss though metabolic acids:
http://www.springerlink.com/content/35211uv240638198/
http://jn.nutrition.org/cgi/content/abstract/111/3/553
http://jn.nutrition.org/cgi/reprint/120/1/134.pdf
https://www.msu.edu/~corcora5/food/vegan/calcium+protein.html
http://www.ajcn.org/cgi/content/full/75/4/609
So as we can see the intake of animal proteins has a negative effect on bone unlike soy that has a positive effect on bone density. So they either deliberately lied or got their facts backward.
Myth: Modern soy foods protect against many types of cancer.
Truth: A British government report concluded that there is little evidence that soy foods protect against breast cancer or any other forms of cancer. In fact, soy foods may result in an increased risk of cancer.
The truth is that numerous studies have shown the anti-cancer effects of soy isoflavones. So all I can conclude is that the British government has not learned how to read medical studies:http://curezone.com/forums/fm.asp?i=1536933#i

"There are growing body of experimental evidence that show the inhibition of human cancer cells by genistein through the modulation of genes that are related to the control of cell cycle and apoptosis. Moreover, it has been shown that genistein inhibits the activation of NF-kappa B and Akt signaling pathways, both of which are known to maintain a homeostatic balance between cell survival and apoptosis. Genistein is commonly known as phytoestrogen, which targets estrogen- and androgen-mediated signaling pathways in the processes of carcinogenesis. Furthermore, genistein has been found to have antioxidant property, and shown to be a potent inhibitor of angiogenesis and metastasis. Taken together, both in vivo and in vitro studies have clearly shown that genistein, one of the major soy isoflavones, is a promising reagent for cancer chemoprevention and/or treatment. "

Myth: Soy foods protect against heart disease.
Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol improves one’s risk of having heart disease.
The truth is: ROTFLMAO!!!! Are they really that stupid to think that cholesterol would be the only factor in heart disease? In fact high cholesterol has NOTHING to do with heart disease. But soy does provide silica that keeps the artery walls flexible and free from inflammation that leads to cholesterol build up. Soy also contains sterols that lower blood pressure that would could otherwise lead to damage and cholesterol build up. And soy contains phytic acid, which they pointed out clears up iron. To be a lot more specific phytic acid has a high affinity for toxic heavy metals and free iron that can contribute to oxidative damage and plaque formation.
Myth: Soy estrogens (isoflavones) are good for you.
Truth: Soy isoflavones are phyto-endocrine disrupters. At dietary levels, they can prevent ovulation and stimulate the growth of cancer cells. Eating as little as 30 grams (about 4 tablespoons) of soy per day can result in hypothyroidism with symptoms of lethargy, constipation, weight gain and fatigue.The real truth is: Soy helps to prevent cancer and excess estrogen issues as evidenced above. And through the same mechanism of antagonizing estrogen soy has also been shown to help maintain bone density and balance the hormones, which helps prevents the symptoms they claim. On the other hand beef and dairy are well known for causing these side effects in part due to their high estrogen levels, poor digestion and toxins they provide to the body such as uric acid.
Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years.
Truth: Soy foods can stimulate the growth of estrogen-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause.The real truth is that these claims have already been proven false above and in other posts.
Myth: Phytoestrogens in soy foods can enhance mental ability.
Truth: A recent study found that women with the highest levels of estrogen in their blood had the lowest levels of cognitive function; In Japanese Americans tofu consumption in mid-life is associated with the occurrence of Alzheimer’s disease in later life.I already addressed this here:
http://curezone.com/forums/fm.asp?i=1538298#i
We also have to keep in mind that soy is also a good source of lecithin, which has compounds that help with building both brain tissue and acetylcholine associated with improved memory. So did this study take in to account other factors such as other things in the diet like beef and dairy. Note that the study found women with the highest level of "estrogen" in their blood. Unlike meats and dairy soy DOES NOT raise estrogen levels. In fact as I have shown the phytoestrogens in soy ANTAGONIZE stronger estrogens such as those found in meats, dairy and that are produced by the human body. These strong estrogens from animals and produced by the body will interfere with thyroid function if not antagonized leading to a decline in cognitive function. Therefore we can conclude that soy is unlikely to have been a culprit since it does not raise estrogen levels above normal like beef and dairy can or during menopause or with certain endocrine disorders.

Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status.
Truth: Archer Daniels Midland (ADM) recently withdrew its application to the FDA for GRAS status for soy isoflavones following an outpouring of protest from the scientific community. The FDA never approved GRAS status for soy protein isolate because of concern regarding the presence of toxins and carcinogens in processed soy.
The real truth is: ROTFLMAO!!! Did they really think nobody would check to see if they are lying?!!! From the FDA's own website the GRAS approvals for soy products:http://www.accessdata.fda.gov/scripts/fcn/fcnDetailNavigation.cfm?rpt=scogsLi...

Myth: Soy foods are good for your sex life.
Truth: Numerous animal studies show that soy foods cause infertility in animals. Soy consumption enhances hair growth in middle-aged men, indicating lowered testosterone levels. Japanese housewives feed tofu to their husbands frequently when they want to reduce his virility.The real truth is: LOL!!!! This is some of the funniest garbarge I have seen in a long time. First of all studies have shown no effect of soy on sperm.:
http://curezone.com/forums/fm.asp?i=1542259#i
And how do they explain the ultra-high population of people in China where soy products are a major component of the diet if it reduces virility and fertility?
And low testosterone does not increase hair growth. Things like facial and chest hair are increased by increased levels of testosterone, but lower levels do not increase hair growth. Seriously, what were these people smoking when they thought this garbage up? Highly estrogenic marijuana?!!! Or maybe they overdosed on highly estrogenic beer! The role of testosterone on scalp hair is when it converts to the more radical dihydrotestosterone (DHT), which kills the hair follicle to die and the hair falls out. This is known as male pattern baldness (MPB). What phytoestrogens can do is to act as DHT blockers preventing hair loss. This is why oils like sesame oil are used in some countries to prevent hair loss. Licorice root, saw palmetto, pygeum and other herbs also help by acting as DHT blockers.
Myth: Soy beans are good for the environment
Truth: Most soy beans grown in the US are genetically engineered to allow farmers to use large amounts of herbicides.The real truth is: Why would they think that genetically altering plant for insect resistance would require more use of herbicides? Use some common sense people!!! If the bugs cannot eat the soy then what are they going to eat? Maybe the weeds?
Myth: Soy beans are good for developing nations.
Truth: In third world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations.
http://www.soyonlineservice.co.nz/03soymyths.htmDo they have any evidence of this or is this just more unsubstantiated soy bashing? And have they considered that "traditional crops" change all the time? Do you think watermelons and tomatoes are from North America? What about wheat? Bananas? Should I go on with the long list of non-native crops being grown in the US?
Other studies raise concerns about soy's effect on hormones, for example: One study found that children with autoimmune thyroid disease are more likely to have been fed soy-based infant formula.
The real truth is that "more likely" is hardly a proof of correlation. In fact I ran several searches looking for any human studies showing a link between soy intake and Hashimoto's and there were NONE!!! Probably because soy has nothing to do with autoimmune thyroid conditions. If you do your homework you will find that autoimmune conditions stem from adrenal dysfunction and nearly every autoimmune condition has been proven to have a microbial trigger. Soy is not a microbe and it does not suppress the adrenals.
A 1991 Japanese study found that soy consumption can suppress thyroid function and cause goiters in healthy people, especially elderly subjects.The real truth is that cooking or fermenting soy inactivates the goitrogenic activity of soy. Do you know anyone who eats raw soybeans? I also find it interesting that they always claim these studies exist but they don't link or post them. And when you go to look for them they are nowhere to be found. This is a great example of what I have mentioned in the past about it is easy to make any claim, but it is impossible to prove when you are making the claim up. This is why when people claim studies exist but don't provide them they usually do not exist.
Czech researchers in 2006 reported on a study that looked at thyroid hormones and thyroid autoantibodies, along with blood levels of two isoflavones -- daidzein and genistein. The study looked at children without overt thyroid disease, who were not iodine deficient. They found a "significant positive association of genistein with thyroglobulin autoantibodies and a negative correlation with thyroid volume." They concluded that "even small differences in soy phytoestrogen intake may influence thyroid function, which could be important when iodine intake is insufficient.""When iodine is insufficient. This has been pointed out in the past. In fact I mentioned a few days ago that the traditional Asian diet also includes seaweeds high in iodine. Also keep in mind that cooking and fermentation eliminates the goitrogenic effect and we get iodine from other food sources. So unless you are eating a diet of raw soybeans and nothing else the risk is basically non-existent. On the other hand other goitrogenic foods commonly eaten raw could be a big factor such as flax seed, which has about two times more goitrogenic activity than raw soy. Other goitrogens commonly eaten raw include cabbage, broccoli, onions, peaches, spinach, peanuts, turnips....
In 2004, researchers found that infants fed soy formula had a prolonged increase in their thyroid stimulating hormone (TSH) levels, compared to infants fed non-soy formula.
Again, where is the study? If you really want to prove a point then provide the proof, not hearsay!!!
European researchers found in one study that even a week of consuming unprocessed boiled natural soybeans caused modest changes to thyroid levels."Unprocessed boiled natural soybeans"?!!! Isn't boiling processing? And are their synthetic soybeans? And again, where is the study?
A 1997 study published in the journal Biochemical Pharmacology wrote: "it was observed that an...extract of soybeans contains compounds that inhibit thyroid peroxidase- (TPO) catalyzed reactions essential to thyroid hormone synthesis
I have only seen one study on this and it was a rat study. We are not rats, nor do we react the same to substances as rats. i posted on this study and provided human studies showing that soy does not affect the thyroid in humans here:

This is a reply to # 1,548,646Here are the results of "the biggest human study into the effects of soy on fertility" - their words not mine.
http://www.theage.com.au/national/soy-products-linked-to-low-sperm-count-2008...
FIRST it was tight jeans and hot spas, but now research suggests soy-based products may reduce a man's sperm count.
A study that monitored the soy consumption of 99 men has found those who consumed more than two portions of soy-based foods a week had, on average, 41 million fewer sperm per millilitre of semen than men who had never eaten soy food.
The apparent fall in sperm count is unlikely to make healthy men infertile, but some experts said it could have a significant impact on those already with lower than average sperm counts. A sperm count of 80 million to 120 million per millilitre is regarded as normal, while men who produce fewer than 20 million sperm per millilitre are regarded as clinically subfertile.
As a cheap source of protein, soy-based products have risen steadily in western diet popularity since the 1940s and are now included in many products, including biscuits, sweets, pasta and bread.
The study, by Dr Jorge Chavarro at Harvard school of public health in Boston, builds on research in animals and on human tissues that has suggested certain ingredients in soy could harm sperm production.
In the biggest human study into the effects of soy on fertility, Dr Chavarro and colleagues at Massachusetts General Hospital recruited 99 men who had visited a fertility clinic between 2000 and 2006. They were asked to fill out a survey which asked them about the amounts of 15 different soy foods they had eaten over the previous three months.
The researchers then divided the men into four groups according to the levels of chemicals called isoflavones in their diets. (Isoflavones are ingredients in soy products that mimic the female sex hormone, oestrogen.) Each man then provided a sperm sample for testing.
Dr Chavarro found that men who consumed at least half a portion of soy food a day had the lowest sperm count. "Our findings suggest that the greater the soy food intake, the lower the sperm concentration, compared with men who never consume soy food," said Dr Chavarro, whose study appears in the journal Human Reproduction.
Also i will post this article because something like 90-95% of soy in the US is GM

Women who eat Genetically-Modified foods while pregnant risk endangering their unborn babies, startling new research suggests.
The study - carried out by a leading scientist at the Russian Academy of Sciences - found that more than half of the offspring of rats fed on modified soya died in the first three weeks of life, six times as many as those born to mothers with normal diets. Six times as many were also severely underweight.
The research - which is being prepared for publication - is just one of a clutch of recent studies that are reviving fears that Genetically-Modified food damages human health. Italian research has found that modified soya affected the liver and pancreas of mice. Australia had to abandon a decade-long attempt to develop modified peas when an official study found they caused lung damage.
And last May this newspaper revealed a secret report by the biotech giant Monsanto, which showed that rats fed a diet rich in Genetically-Modified corn had smaller kidneys and higher blood cell counts, suggesting possible damage to their immune systems, than those that ate a similar conventional one.
The United Nation's Food and Agriculture Organisation held a workshop on the safety of genetically modified foods at its Rome headquarters late last year. The workshop was addressed by scientists whose research had raised concerns about health dangers. But the World Trade Organisation is expected next month to support a bid by the Bush
administration to force European countries to accept GM foods.
The Russian research threatens to have an explosive effect on already hostile public opinion. Carried out by Dr Irina Ermakova at the Institute of Higher Nervous Activity and Neurophysiology of the Russian Academy of Sciences, it is believed to be the first to look at the effects of GM food on the unborn.
The scientist added flour from a GM soya bean - produced by Monsanto to be resistant to its pesticide, Roundup - to the food of female rats, starting two weeks before they conceived, continuing through pregnancy, birth and nursing. Others were given non-GM soyaand a third group was given no soya at all.
[B]She found that 36 per cent of the young of the rats fed the modified soya were severely underweight, compared to 6 per cent of the offspring of the other groups. More alarmingly, a staggering 55.6 per cent of those born to mothers on the GM diet perished within three weeks of birth, compared to 9 per cent of the offspring of those fed normal soya, and 6.8 per cent of the young of those given no soya at
all.[\B]
"The morphology and biochemical structures of rats are very similar to those of humans, and this makes the results very disturbing" said Dr Ermakova.
"They point to a risk for mothers and their babies."
Environmentalists say that - while the results are preliminary - they are potentially so serious that they must be followed up. The American Academy of Environmental Medicine has asked the US National Institute
of Health to sponsor an immediate, independent follow-up.
What the experiment found
Six times as many of the offspring of those fed the modified soya were severely underweight compared to those born to the rats given normal
diets.
Within three weeks, 55.6 per cent of the young of the mothers given the modified soya died, against 9 per cent of the offspring of those fed the conventional soya.Advertisement

Does Soy Really Lower Sperm Count?
As a guy, I don’t want hear that anything is bad for the boys, but new research by the Harvard School of Public Health insists that even eating half a serving of soy food a day lowers sperm concentrations.
The study appears in the journal of Human Reproduction. Here’s the abstract via PubMed:
BACKGROUND: High isoflavone intake has been related to decreased fertility in animal studies, but data in humans are scarce. Thus, we examined the association of soy foods and isoflavones intake with semen quality parameters.
Relax, don’t freak out just yet. “It's way too early to say stop eating soy foods. It's not time to worry about whether you're eating too much soy. There's not enough information to conclusively say that,” lead researcherDr. Jorge Chavarro, M.D., a research fellow at the Harvard School of Public Health, told Steven Reinberg ofHealthDay News.
METHODS: The intake of 15 soy-based foods in the previous 3 months was assessed for 99 male partners of subfertile couples who presented for semen analyses to the Massachusetts General Hospital Fertility Center. Linear and quantile regression were used to determine the association of soy foods and isoflavones intake with semen quality parameters while adjusting for personal characteristics.
RESULTS: There was an inverse association between soy food intake and sperm concentration that remained significant after accounting for age, abstinence time, body mass index, caffeine and alcohol intake and smoking. In the multivariate-adjusted analyses, men in the highest category of soy food intake had 41 million sperm/ml less than men who did not consume soy foods (95% confidence interval = -74, -8; P, trend = 0.02). Results for individual soy isoflavones were similar to the results for soy foods and were strongest for glycitein, but did not reach statistical significance. The inverse relation between soy food intake and sperm concentration was more pronounced in the high end of the distribution (90th and 75th percentile) and among overweight or obese men. Soy food and soy isoflavone intake were unrelated to sperm motility, sperm morphology or ejaculate volume.
CONCLUSIONS: These data suggest that higher intake of soy foods and soy isoflavones is associated with lower sperm concentration.
And just to be sure, I asked Dr. Fuhrman for his thoughts on this study. Here’s what he had to say:
This study showed that high levels of processed soy foods, not edamame or unprocessed soy beans, may lower sperm counts in obese men.
When most people think soy, they think soy ice cream or soy “meat” products. They forget about edamame beans. Edamame beans are nutritional rock stars! From Wikipedia, check this out:
The higher intake of soy foods, lowered sperm counts, but the counts were still in the normal range. Obesity increases the body’s estrogen production, and the extra pro-estrogenic effects of soy apparently was enough to reduce sperm levels, in these overweight men whose estrogen levels were already somewhat elevated due to their heightened body weight.
Fiber-rich carbohydrates such as edamame help prevent mood fluctuations by keeping blood-sugar levels steady. Edamame also contains protein, which further helps stabilize blood sugar, and omega-3 fatty acids.
And besides, we already know that processed soy foods are NOT something you want to base your diet around. Dr. Fuhrman explains:
Edamame beans contain higher levels of abscissic acid, sucrose, protein than other types of soybean. They also contain a high source of vitamin A, vitamin B and calcium.
Studies have shown soy's beneficial effects on cholesterol and other cardiovascular risk factors. However, there is no reason not to expect the same results from beans of any type--it's merely that more studies have been done on soy than on any other beans. There are numerous studies indicating that soybeans are rich in various anti-cancer compounds such as isoflavones. Most beans are rich in these beneficial anti-cancer compounds, and many different flavonoids with anti-cancer effects are found in beans of various color. I always recommended the consumption of a broad variety of phytochemical-rich foods to maximize one's health. Beans are no exception--try to eat different types of beans, not just soy.
So I think the real point to take away from this study is processed soy foods are not health-promoting and being overweight or obese lowers male fertility. For more on that, read: Obese men have less semen, more sperm abnormalities, and should lose weight before trying for a baby—via EurekAlert!
You should be aware that soy nuts, soymilk, and other processed soy products do not retain many of the beneficial compounds and omega-3 fats that are in the natural bean. The more the food is processed, the more the beneficial compounds are destroyed. Remember, though, tofu and frozen or canned soybeans are a good source of omega-3 fat and calcium.
Most of the processed soy products can be tasty additions to a plant-based diet, but they are generally high in salt and are not nutrient-dense foods, so use them sparingly. In conclusion, the soybean is a superior food, containing the difficult-to-find omega-3 fats. Beans in general are superior foods that fight against cancer and heart disease, which is why you will benefit from using a variety of beans in your diet.

When you take into account the amount of processed soy , Genetically-Modified soy and canned soybean (BPAs) the amount of natural soy eaten is small in comparison.Regardless it would be good to have exactly the same study done but with people eating only unprocessed non-GM soybeans (if this is even possible anymore) - Re: Soy myths part 1 Maniek

This is a statistically significant trend = 0.02? (0.001)
ROTFLMAO!!! I love how you are trying to manipulate what was really said by only quoting a fraction of what was really said. This is typical of people who do not have a clue what they are talking about. So they twist things to BS people. So everyone can see the poor game you are playing here is what you quoted from and left out the part about "95% confidence interval". So you don't think that 95% is "statistically significant"?
(95% confidence interval = -74, -8; P, trend = 0.02)

he Gerson therapy for difficult to digest carefully are:
-soy, seafood, milk, nuts, peanuts
And are in principle prohibited talking about treatment and not prevention.
Soy is rich in fat and contains 30 allergens, phytic acid blocking the absorption of important minerals, protease enzymes Stop the healing power of live enzymes contained in fruit juices, and substances that increase the clotting. There is also the question even with soy is a stimulant malignancies. In the face of the uncontrolled flood of GM soya soya I personally confined to a minimum.
Note!
Also, sprouts, and juice from the grass of the wheat is not desirable because a sick body can not cope with the harmful side effects. Wheat grass Irritant stomach.
Uninterruptable - The Gerson terapy.
There is also an excellent book in my view, a cohesive, all therapies that are not recognized by the consensus of medicine.
