CONFIRMED: SOY HAS NO ESTROGEN & NO EFFECT on MEN'S TESTOSTERONE - VEGANS HAD MORE TESTOSTERONE THAN OMNIVORES

Posted Mar 21 2012 5:56am

THE SOY ESTROGEN & "DANGERS OF SOY" MYTH IS NOW FOUND TO BE AN INTERNET HOAX TRACED TO A KNOWN FRONT-GROUP CALLED THE WAPF.

 

Here is the actual information:

 

SCIENTIFIC EVIDENCE:

STUDY: SOY DOES NOT HAVE FEMINIZING EFFECTS ON MEN - VERIFIED

ANALYSIS: "Soybean isoflavone exposure does not have feminizing effects on men" - NIH National Institute of Health

"Neither isoflavone supplements nor isoflavone-rich soy affect total or free testosterone levels. Clinical evidence also indicates that isoflavones have no effect on sperm. There is essentially no evidence from the nine identified clinical studies that soy isoflavone exposure affects estrogen levels in men."

http://www.ncbi.nlm.nih.gov/pubmed/20378106

LABORATORY TESTS NOW CONFIRM THE SOY-ESTROGEN MYTH WAS A HOAX:


SCIENCE: "Review finds NO Effect of soy on testosterone" - METAREVIEW STUDY


Despite rumours often spread on the internet, "A review of 15 studies into the influence of soy proteins or isoflavones on male hormones has found No evidence of an estrogen-like effect."

These rumours stemmed from a handful of flawed reports. "The authors criticized the studies that reported lowered testosterone levels for their methodology."

One of them had only 12 subjects in it. In another, the researchers forgot to include a control, and final readings, rendering their results useless. In another one the entire result was due to just 1 subject.

The dangers-of-soy scares are all based on flawed science.

It was actually found that Soy does not cause breast cancer, protstate cancer, thyroid problems, infant formula problems, or estrogenic effects, on the contrary "Eating soy demonstrated protection against breast cancer, prostate cancer, and heart disease."

Eating Soy was confirmed benficial. For women, children, and indeed men.

METASTUDY: REVIEW SPANNING VOLUMES OF MULTIPLE STUDIES SHOW NO ESTROGENIC EFFECT OF SOY ON MEN'S TESTOSTERONE

PUBMED JOURNAL: "Clinical studies show no effects of soy protein or isoflavones on reproductive hormones in men"


"32 reports involving 36 treatment groups and 15 placebo-controlled treatment groups with baseline and ending measures involving soy, isoflavones, genistein, phytoestrogens, red clover, androgens, testosterone, and SHBG, were analyzed. CONCLUSION: The results of this meta-analysis found that neither soy foods nore soy isoflavone supplements alter measures of bioavailable Testosterone concentrations in men. There was no effect.

REVIEW FINDS NO SUCH EFFECT OF SOY ON MEN OR TESTOSTERONE:

NEWS: "Scientific Review finds no effect of soy on testosterone"
By Caroline Scott-Thomas, 30-Jun-2009


"Results suggest that consumption of soy foods or isoflavone supplements would Not result in the adverse effects associated with lower [testosterone] levels."

"No significant effects of soy protein or isoflavone intake on T [testosterone] or SHBG [sex hormone-binding globulin] were found." There was no effect of soy on testosterone.

AMERICAN INSTITUTE FOR CANCER RESEARCH: SOY HAS NO ESTROGEN, SOY ESTROGEN MYTH IS AN UN-SCIENTIFIC HOAX.

AICR: "Men Don't Need to Fear Soy Foods" -American Institute for Cancer Research

It’s no wonder that men who have read the recent stories circulating about soy are confused. Some stories claim that soy foods, such as tofu and soy milk, can lead to breast growth or reduce testosterone levels.

- Fears that the amount of phytoestrogens in moderate amounts of soy foods could stimulate men’s breast tissue or reduce their testosterone are not based on sound research.

- A study of children fed soy protein formula for more than six months showed no hormonal effects.

- A study of men found that the men who ate soy foods twice a day for three months showed NO change in testosterone levels.

- Soy does not cause prostate cancer, on the contrary, the studies showed eating soy by men was beneficial in lowering the risk of prostate cancer.

Men can feel safe.

SCIENCE: NOT ONLY DOES SOY *NOT* CONTAIN ESTROGEN, SOY BLOCKS ESTROGEN

SCIENCE NEWS: "Soy Phytoestrogens May Block Estrogen Effects"

"Isoflavones may protect against the more powerful estrogen produced by the body."

"The addition of high levels of dietary soy isoflavones tended to block estrogen." -Senior investigator J. Mark Cline, D.V.M., Ph.D.

BODYBUILDING MAGAZINES CONFIRM IT:

MUSCULAR DEVELOPMENT MAGAZINE:

"SOY PROTEIN HAS *NO* EFFECT ON TESTOSTERONE LEVELS"

"The meta-analysis examined 47 research reports covering 51 treatment groups. Peer-reviewed studies. The analysis concluded that neither soy protein nor isoflavone supplementation exerted any negative alterations on bioavailable testosterone in males, regardless of research model.

Soy did not exert any estrogen-like effects in men, nor any lowering of testosterone levels or other reproductive hormones."

IRON-MAN MAGAZINE CONFIRMS:

SOY PROTEIN HAS NO EFFECT ON MEN, SOY HAS NO EFFECT ON TESTOSTERONE

IRONMAN MAGAZINE: "Eating soy has No effect on either testosterone or estrogen levels"


"You see the caution on countless Internet sites related to bodybuilding: Avoid eating soy products unless you want to lower your testosterone count. At first glance the dire warnings about soy are plausible...However, actual scientific research found that soy protein and isoflavone intake had No significant effects on testosterone.

Neither total nor free testosterone was negatively affected by dietary soy in Any of the studies. None.

Also, Studies confirmed Soy has no negative effect on thyroid hormones.

Both whey and soy proved superior to casein in aiding muscle protein synthesis in young men.

Eating soy will have no effect on either testosterone or estrogen. - STRAIGHT FROM "IRONMAN BODYBUILDING" MAGAZINE

IRONMAN BODYBUILDING MAGAZINE: "Researchers confirm soy has No effect on testosterone"

Soy doesn't increase estrogen, soy phytoestrogen isoflavones BLOCK estrogen from affecting men.

"Since the soy isoflavones are so weak, they block the effects of estrogen." 15 placebo-controlled studies and 32 reports on 36 treatment groups once-and-for-all confirmed that soy protein or isoflavone intake had no significant effects on testosterone.

The Soy is bad, soy is evil, myth is not only debunked, soy is actually beneficial.

Soy helped reduce fat. Helped in fatloss and weight-loss. Built protein & muscle.

"Soy protein seems to be particularly potent in reducing fat stored in muscle."

Soy now shown excellent for bodybuilding.-Ironman Bodybuilding Magazine.

"If anything, soy’s moderate effect on cortisol would be good for those engaged in bodybuilding."

(Note: it's not even appropriate to avoid it just to be 'playing it safe', because those who are Not eating soy, will be be more affected by the Estrogen in steak and meat. Men who eat Soy will have less estrogenic effects than meat eaters. Plus soy protects men against prostate cancers, and reduces fat in muscle making it excellent for bodybuilding.) - IRONMAN BODYBUILDING MAGAZINE.

THE (TRUE) WHOLE SOY STORY:

SOY DOES NOT CAUSE BREAST CANCER, PHYTOESTROGENS AID AGAINST CANCER.

SCIENCE: "Soy Phytoestrogens May Block Estrogen Effects"

"Plant estrogens found in soy do not increase markers of breast cancer risk in postmenopausal women. In fact, they may provide a protective effect.

"Even at high doses, we found No evidence that the estrogen-like compounds in soy, called isoflavones, stimulate cell growth or other markers for cancer risk in breast tissue."-Charles E. Wood, D.V.M., Ph.D

"The study also suggests that women who have higher levels of estrogen may actually gain a protective effect from higher doses of soy isoflavones."

"Population studies show that women who consume diets high in soy generally have lower rates of breast cancer." - Cancer Center.

SCIENTIFIC CONFIRMATION:

SOY DOES NOT CAUSE PROSTATE CANCER, SOY HELPS AGAINST IT.

SCIENCE: Prostate & Soy - Scientific study by the National Institute of Health

No testosterone level decrease was found, in a randomized soy intervention among men.

Study was conducted "to investigate the effects of daily soy intake on serum prostate-specific antigen (PSA) and testosterone levels. No change in testosterone was observed during a HIGH soy diet in contrast to the avoiding soy diet." 

"No significant between-group and within-group differences were detected."

The study found beneficial results of eating soy: soy lowered the risk of Prostate Cancer.-European Journal of Clinical Nutrition

http://www.ncbi.nlm.nih.gov/pubmed/16775579

[In other words, Men who ate tofu were cleaner of cancer, had higher levels of beneficial SHBG, and had no such lowered testosterone. Men who avoided Tofu and Soy, "just to be safe", ended up not being safe. By avoiding soy, the Men who avoided eating soy and tofu ended up with higher instances of cancer in the vicinity of their genital region. Specifically the prostate. Cancer is not safe.]

THE "SOY MYTH" HAS BEEN TRACED TO A KNOWN HEALTH-FRAUD GROUP IDENTIFIED AS "THE WESTON A. PRICE FOUNDATION" (WAPF) WHICH SPREADS FALLACIOUS MEDICAL INFORMATION

LOOK:
http://www.quackwatch.org/01QuackeryRelatedTopics/holisticdent.html




WAPF MEMBERS ARE EXPOSED MAKING UN-SCIENTIFIC SOY HEALTH CLAIMS:
http://www.allnaturalhealthylife.com/news/is-soy-safe/

 


DANGEROUS WAPF FRONT-GROUP MEMBERS IDENTIFIED:
- Joseph Mercola - [Cited by Federal Authorities for false health claims]
- Barry Groves - [Found to have fake degree purchased from diploma mill]
- Sally Fallon Morell
- Mary G Enig
- Julia Ross
- Kaayla T Daniel
- Dr. William Campbell Douglass - [Weston A. Price WAPF honorary member William C. Douglass has fled US Authorities to South America to evade the authorities and is now posting fraud articles via the internet from Panama]

 
Note: The WAPF, known as the Weston A. Price Foundation sets out to dupe people, mainly focused at Americans, by purporting that it is on their side and appearing to 'take a stand' for ingesting things that are either known or can potentially cause them damage, or harm the health of their families and children. In this way, the WAPF can subtly inflict slow damage to a person's family. Meanwhile the person whose family or child is slowly being damaged has been duped so badly that they even may for a time fight on the side of the WAPF, until they find out eventually that the information from the WAPF was fabricated, misleading, or based on falsified information simply made to appear 'scientific-looking'. Weston A. Price WAPF honorary board-members have also been caught issuing anti-american propaganda, for instance "Dr" William Campbell Douglass of the WAPF, and praised by WAPF board-member Sally Fallon, spread articles purporting that the U.S. and Americans "created" the HIV AIDS virus (on purpose) and that America unleashed Aids on the world as part of a genetic engineering biological warfare plot by America. This is of course, completely false, but this is the type of rhetoric that has been put forth by the WAPF, traced to honorary Weston A. Price member Dr. William Campbell Douglass. This is the WAPF member now hiding in Panama after fleeing the US to South America in order to evade enforcement. This same individual tied to the WAPF spread health articles detailing how smoking cigarettes is actually 'great' for your health. He argued for readers to not believe 'big government' and that the 'hype' about smoking causing cancer is a lie, and that you should even encourage your children to smoke, because 'everything is safe in moderation'. In this respect, the WAPF is often classified as an Anti-American front group, because its members have been found pushing information that has been later found damaging to American citizens. For example, WAPF member William Campbell Douglass also told people in his online blog that the toxic pesticide DDT is "SAFE" for your child to eat. He also wrote articles telling people to inject their children with hypodermic needles full of hydrogen peroxide, because it was a healthy way to cleanse their system. Nevertheless, many people lesser-educated in actual science still remain duped by the WAPF. Some un-wittingly even stand up for, and praise, and quote the Weston A. Price Foundation, not knowing that much of the information is pseudo-science, hurtful, or fallacious.

 

EXAMPLE OF FEDERAL AUTHORITIES CITING WAPF MEMBER:

 

NEWS: "FDA Orders Dr. Joseph Mercola to Stop his Illegal Claims"

Both Kaayla T Daniel and Joseph Mercola are tied to the Weston A. Price Foundation.

Here is a documented legal Federal warning letter issued against Dr. Joseph Mercola for making more false health claims on Mercola.com.

Like Daniels, Mercola also goes around tearing down grain, advocating unhealthy no-grain diets, the now-debunked paleo-style diet, primal diets that ranked in last place in health by nutrition experts in USNEWS & World Report (24th out of 24 - Paleo came in last place), advocating potentially bacterially infected raw milk, and other spurious quack claims. This time Mercola was caught making claims not backed by scientific evidence and socked by federal authorities with a FEDERAL CITATION for making false scientific claims in order to peddle books and products.

ACTUAL SOY CANCER INFORMATION:

SOY DOES NOT CAUSE CANCER - SOY HELPS AGAINST CANCER.

ONCOLOGY JOURNAL: "Soy compounds may boost cancer treatment effectiveness: Mouse study" - Radiotherapy & Oncology Journal

"Research showed that Soy isoflavones can help make radiation treatment of lung cancer tumours more effective while helping to preserve normal tissue. Isoflavones extracted from soybeans show potential in boosting the effectiveness of cancer treatments. Writing in Radiotherapy and Oncology, researchers report that soy isoflavones enhanced the destruction of lung tumours by radiation, whilst also reducing vascular damage, inflammation and fibrosis caused by radiation injury to normal lung tissue."

SOY AND WOMEN:
SOY DOES NOT CONTAIN ESTROGEN AND DOES NOT CAUSE BREAST CANCER:


NEWS: "Dietary soy containing phytoestrogens does not have detectable estrogenic effects on hepatic protein synthesis in postmenopausal women"

"Dietary soy isoflavones do not affect in vivo biological indicators of estrogenicity, including hepatic protein synthesis and gonadotropin concentrations. This suggests that soy isoflavones have little biologically relevant estrogenic effect"

http://www.ajcn.org/content/79/3/396.full


[Please note here, that what the WAPF front-group, and others, do, is first seed articles that attempt to make POSITIVE claims, usually on the order of miraculous, and then once drummed up, the WAPF will swoop in to supposedly 'reveal' them and defeat them. Then they will make negatively extremist claims working on that basis. For example, you will see first, articles seeded that claim soy is such a miracle, and a veritable "cure" for cancer, and then the actual more modest health claims of soy incorrectly inflated, to make it appear like it's too good to be true, then WAPF will supposedly 'debunk' these 'miracles', which were merely invented in the first place. The idea to takeaway from this, is that NEITHER is the case. Soy is not a "cure" for breast cancer, and neither does Soy cause breast cancer. False front groups like the WAPF and follow-ons first attempted to set up that soy should be able to work miracles being effective against estrogen-dependent breast cancer supposedly because soy contained so much estrogen(false). Well, of course soy was found not to magically cure breast cancer--because lo & behold soy does not contain any estrogen in it in the first place. It only has the plant-analog called phytoestrogen which does not affect humans, soy has no estrogen in mammalian form that can actually affect you estrogenically at all, so of course it's not a miracle cure, and so the WAPF could now swoop in and say "see. soy is no miracle cure afterall. it's all hype." Of course, they knew this already. And after supposedly 'revealing' that soy is not magic, its health food properties hyped, then they can swoop in and build on that foundation to lead people to believe it's actually harmful or even 'causes' cancer. If you're confused after this, that's their exact strategy. That's their plan. The WAPF doesn't only need people to believe their soy misinformation, the WAPF also counts you as a victory if they've succeeded in confusing the public, raising so much doubt, that people are now merely 'unsure' of what to believe now, since they've heard and seen all kinds of things, so now what you do is 'avoid it'. That's a WAPF victory. Any person they've tricked into being even unsure such that they now believe they need to 'play it safe' or 'had better simply just avoid it' for now, is a cheer for the WAPF, as this means they've succeeded in raising Fear, Uncertainty, and Doubt (FUD), in yet another of their victims if you believe the WAPF or just think you're 'playing it safe' because you're avoiding it.That means you've allowed the front group to win. Simply making Americans confused they count as a Victory. -- So what's the actual story? It's simple. Eating soy does NOT cause breast cancer. But that also doesn't mean soy is some miraculous cure for it. What this study shows, is that eating soy was healthy, and had neither any miraculous curing effect on cancer, nor did it cause it. There's nothing wrong with soy, it's simply moderately part of a healthy diet, and it had no dangers or damaging effects on breast cancer, nor is it some miracle. Soy does NOT contain mammalian estrogen. And had no significant estrogenic effects, and therefore it cannot be used as a cure, and neither is a cause. Any effects that appeared to come from eating soy, may have likely been from the fact that if the person was eating healthy soy and tofu, they likely may have been eating LESS RED MEAT. And if they were eating tofu burgers which are found not to cause cancer, instead of red meat which indeed has been linked to various cancers, that may be the reason behind the fact that it appeared eating soy drastically reduced cancer. It may have been simply the lower incidence of cancer due to eliminating the ingestion of quantities of meat.

STEAK & MEAT CONTAINS ACTUAL MAMMALIAN ESTROGEN.
SOY DOES NOT CONTAIN ESTROGEN.

IT IS STEAK THAT HAS ACTUAL ESTROGEN IN IT.
MEAT IS WHAT CONTAINS THE ACTUAL FORM OF ESTROGEN THAT IS DANGEROUS.


This picture below shows proof of actual estrogen implants which are right now being used by meat farmers in your meat. These are actual ampules of estradiol, which is the actual mammalian-form estrogen. Isoflavones in soy come from a Plant. Notice the word "PHYTO" in the word phytoestrogen which is in soy. The word Phyto- means plant. That's plant generated phytochemicals, that is NOT ESTROGEN. Understand that they are simply using the fact that the suffix part of the word has the letters for estrogen in it, to dupe you into believing that that's the same as women's estrogen. It's not. It's completely different. It's the plant form! Phyto means plant. That's not the animal or human form of real estrogen. They are chemically not identical. However, what you see in the image below IS the same as actual FEMALE EFFEMINIZING ESTROGEN. And where it is, is in steak and meat. It's purchaed by cattle farmers, such as the cattlenetwork, and beef farmers have been implanting this hormone into cows, and you've been eating it. You've been eating feminine estrogen residue in your barbequed steak. Please note, that if you believe that you are a manly masculine man, by eating a 'big juicy steak', that in reality, you've all this time been feminizing your tissues every time you ate a steak, or red meat. Namely beef. 99% of all meat, especially in North America, contains female hormones, growth promotants, etc. Oh, and if you thought you were avoiding this by saying you only eat 'grassfed beef' guess what...you've also still been consuming female hormones. Why? Because what the grassfed beef promoters don't tell you, is that the official specifications for what is called Grass-Fed Beef does NOT ban the use of hormones. One more time: Grassfed beef can contain growth hormones. Grass fed beef does not mean organic. Grassfed beef is not necessarily hormone-free. So if you've been eating grassfed beef, and you even had people tell you grassfed beef was safe because it doesn't have hormones because it's Grass-fed, that person just got you to eat potentially effeminizing female hormones, because there is no rule that precludes farmers from injecting female hormones into grassfed beef. Grassfed beef is not guaranteed hormone-free. And Grassfed meat can be soaked with Estrogenic hormones. Even though you may have thought otherwise, that is the actual rule and regulation regarding grassfed beef. Despite what some blog or paleo diet guru, or grassfed beef advocator has told you. 

STEAK AND MEAT POTENTIALLY CONTAIN THE ACTUAL DANGEROUS FORM OF ESTROGEN:

NEWS: MEAT-EATERS DIDN'T HAVE MORE TESTOSTERONE THAN VEGANS. VEGANS DID NOT HAVE MORE ESTROGEN THAN MEAT-EATERS.

STUDY: Oestradiol and sex hormone-binding globulin in premenopausal and post-menopausal meat-eaters, vegetarians and vegans

HV Thomas 1,2 , GK Davey 1 and TJ Key 1

1 Imperial Cancer Research Fund Cancer Epidemiology Unit, Gibson Building, Radcliffe Infirmary, Oxford OX2 6HE, UK; 

2 Department of Psychological Medicine, University of Wales College of Medicine, Heath Park, Cardiff CF4 4XN, UK

Summary
Endogenous  oestradiol [not soy] is  strongly  associated  with  breast  cancer  risk  but  its  determinants  are  poorly  understood.  To  test  the
hypothesis that *vegetarians have lower plasma oestradiol and higher sex hormone-binding globulin (SHBG) than meat-eaters* we assayed
samples from 640 premenopausal women (153 meat-eaters, 382 vegetarians, 105 vegans) and 457 post-menopausal women (223 meat-
eaters,  196  vegetarians,  38  vegans). 

Vegetarians  and  vegans  had  lower  mean  body  mass  indices  (BMI)  [vegetarians were found to be less fat than people who eat meat] and  had lower  plasma  cholesterol concentrations than meat-eaters [vegetarians had lower cholesterol] , but there were no statistically significant differences between meat-eaters, vegetarians and vegans in pre- or post-menopausal plasma concentrations of oestradiol or SHBG.

Before adjusting for BMI there were small differences in the direction
expected, with the vegetarians and vegans having higher SHBG and lower oestradiol (more noticeable amongst post-menopausal women)
than the meat-eaters. These small differences were essentially eliminated by adjusting for BMI. Thus this study implies that the relatively low
BMI  of  vegetarians  and  vegans  does  cause  small  changes  in  SHBG  and  in  post-menopausal  oestradiol,  but  that  the  composition  of
vegetarian diets may not have any additional effects on these hormones.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2363084/pdf/80-6690546a.pdf

[In other words, being a vegetarian or a vegan has NO effect on your hormones. Meat eaters did not have more testosterone. Vegans did not have more estradiol. In fact, what happened was that the vegans and vegetarians were more fit, less fat, had lower cholesterol, and if anything, vegans had increased SHBG, which are all beneficial.]

Abstract:
Total testosterone (T), total oestradiol (E2) and sex hormone-binding globulin (SHBG) concentrations were measured in plasma samples from fifty-one male vegans and fifty-seven omnivores of similar age. Free T concentration was estimated by calculation.

Iin comparison with the omnivores, the vegans had 7% higher total T (P = 0.250), 23% higher SHBG (P = 0.001), 3% lower free T (P = 0.580), and 11% higher E2 (P = 0.194).

In a subset of eighteen vegans and twenty-two omnivores for whom 4 d diet records were available, there were statistically significant correlations between T and polyunsaturated fatty acids (r 0.37), SHBG and fat (r 0.43 for total fat, 0.46 for saturated fatty acids and 0.33 for polyunsaturated fatty acids), and SHBG and alcohol (r–0.39). It is concluded that a vegan diet causes a substantial increase in SHBG but has little effect on total or free T or on E2.

NEWS: SOY PROTEIN RESULTED IN *LOWER* ESTRADIOL and *HIGHER* TESTOSTERONE LEVELS IN ATHLETES

Study: The Effect of protein source and resistance training on body composition and sex hormones.

The current randomized and blinded intervention study in healthy men demonstrated that protein, irrespective of source (soya protein isolate, soya concentrate, soya-whey mix, whey blend), coupled with resistance training results in a significant enhancement of lean body mass.

There was no significant decrease in serum androgenic hormones following supplementation with any protein intervention. [Including no decrease in testosterone found due to eating soy.]

The biological significance of the sex hormone changes within the current study resulting from lower estradiol, and increased testosterone/estradiol ratio in response to soy and whey supplementation is unknown at this time.

The isoflavone content may affect the magnitude of hormonal change as may the duration of dietary exposure to supplemental isoflavones.

In conclusion, it appears that both soy and whey supplementation in free living resistance training men results in lean body mass accretion without negatively affecting serum androgen levels.

http://www.jissn.com/content/4/1/4


[Athletes Bodybuilding with Soy resulted in gain in lean muscle body mass. Soy had no effect on androgen levels-no effect on testosterone. Soy was no different in terms of its effect on androgens than Whey Protein. Soy isoflavones did not reduce testosterone. Soy phytoestrogen had no effect on humans in the actual measured study. If anything, there was a slight (beneficial) INCREASE in the testosterone/estradiol ratio for men who ate the soy.]

NEWS: OMNIVORES DONT HAVE HIGHER TESTOSTERONE THAN VEGANS.

VEGANS ACTUALLY BEAT MEAT-EATERS IN HIGHER LEVELS OF SHBG.


STUDY: Sex hormone concentrations in male vegans and omnivores

In an investigation of factors thought to influence the risk of developing prostate cancer, concentrations of total testosterone, total estradiol, and sex hormone binding globulin (SHBG) were determined using plasma samples from 108 male subjects (51 vegans and 57 omnivores) who were nonsmokers, were not using long-term medication, and had no history of cardiovascular disease (15). There were no significant differences in mean concentrations of testosterone (total or free) or estradiol between vegans and omnivores, but SHBG was 23% higher in the vegans (P = 0.001). In 40 of these subjects who completed a diet diary, there were statistically significant correlations (adjusted for age, body mass index, and diet group) between total testosterone and polyunsaturated fatty acid intake (partial r = 0.37), and between SHBG and each of total fat, saturated fatty acids, polyunsaturated fatty acids, and alcohol (partial r = 0.43, 0.46, 0.33, and -0.39, respectively).

1. THE SOY CONTAINS ESTROGEN, DANGERS OF SOY, SOY IS EVIL MYTH IS AN INTERNET HOAX.

2. THE SOY ESTROGEN MYTH IS FALSE, AND IT WAS TRACED BACK TO A KNOWN FRONT-GROUP CALLED THE "WAPF" WHICH HAS BEEN FOUND TO SPREAD INCORRECT HEALTH INFORMATION.

3. SOY THYROID MISINFORMATION HAS BEEN FOUND FALSE. THE SOY INFANT FORUMULA HOAX HAS BEEN FOUND FALSE. THE SOY PHYTATE INFORMATION HAS BEEN FOUND DOCTORED UP. THE SOY GENISTEIN POSTINGS ARE DISCREDITED. THE GMO SOY IMPLICATORS WERE FOUND DUBIOUS AS IT IS THE NON-GMO SOY MAINLY USED FOR HUMANS, AND THE GMO VARIETY MAINLY GOES TO ANIMAL FEED. WHICH MEANS SOY GMO MAINLY ENDS UP IN MEAT. EATING MEAT WOULD GET YOU A DOSE OF 50x MORE GMO THAN THE PERSON EATING THE TOFU.

4. SOY DOES NOT CONTAIN ESTROGEN. PHYTOESTROGEN IS A PLANT ISOFLAVONE IT IS NOT IDENTICAL TO MAMMALIAN ESTROGEN. MEAT IS WHAT POTENTIALLY HAS ACTUAL MAMMALIAN FEMININE ESTROGEN. ESPECIALLY BEEF, INCLUDING GRASSFED BEEF.

5. SOY DOES NOT LOWER MEN'S TESTOSTERONE. IN FACT VEGANS HAD HIGHER TESTOSTERONE, MEAT EATERS HAD LOWER TESTOSTERONE.

 

Please make a note of it.
