Soy-Cause Of Adverse Health Exposed:
HHS Director of National Institute of Mind Health (NIMH) Dr. Thomas Insel says, "Soy has estrogen disruptor properties." A former FDA Director Of Centers for Food Safety Dr. Michael Shelby when questioned if soy is an endocrine disruptor replies a straight forward "Yes." HHS, FDA, NIH, USDA acknowledge that endocrine disruptors are highly dangerous to health, especially developmental health.
There is a right to know about the existing vast multitude of published studies all concluding soy is an active hormone disruptor. Hormone disruptors are well-known as highly toxic to health, and especially toxic during most fragile developmental (fetal, infant, child) exposure. To ensure best health, everyone deserves an opportunity to review the following fraction of thousands of existing NIH Pubmed or Toxnet studies all revealing severe and sometimes irreversible soy phyto-toxic adverse effects.
Like environmental estrogens, pesticides, BPA plastics, and pharmaceutical DES estrogens, soy is another hormone disruptor, capable of damaging several hormone systems throughout the brain and body.
Soy's multiple naturally toxic components include; Isoflavone endocrine disruptors: genistein, daidzein, equol, glycitein, phytic acid, heavy metals, anti-nutrients, and soy's natural inhibition of several essential enzymes. You may think you don't eat soy, but only in the USA is it nearly impossible NOT to swallow soy as soy fillers are added to nearly all packaged foods. Pregnant women whose dietary intake includes soy are study proven to transfer soy-contamination to her developing fetus. Feeding your baby soy formula is also repeatedly study concluded as highly risky to your child's health. Alarmingly soy is being added as a filler to infant milk formulas.
1999 FDA Federal Register confirms, "GRAS status of soy did not include thorough evaluation of the safety of potentially harmful (soy) components, e.g. lysioalanine, nitrites and nitrosamines, trypsin inhibitors, phytates and isoflavone (hormone disruptors). Trypsin inhibitors (have) potential effects on pancreatic function.....(causing) deleterious effects in the pancreas. Trypsin inhibitors are responsible for hyperplasia and formation of nodules seen in animal studies...and high levels of trypsin inhibitors in humans can evoke this mechanism."
Janice Oliver, Deputy Director Of FDA Center for Food Safety states that "FDA acknowledges that concerns have been voiced about oossible effects of isoflavones in soy infant formulas on sexual development, neurobehavioral development, immune function, and thyroid disease."
FDA Oliver continues with, "A food is deemed to be misbranded if its labeling is false or misleading." With no Warning labels on soy formulas that reveal FDA acknowledged toxic "concerns" soy infant formulas ARE misbranded.
You will be witness to multiple published studies that in fact reveal soy estrogenic hormone disruptors in many foods, fillers, and formulas marketed in the USA are indeed "Misbranded," as soy phyto-toxic labeling remains FDA withheld from public disclosure.
Factual soy studies reveal a host of toxic effects:
1998, FDA NCTR Reports: Our results may be interpreted that soy phytoestrogen genistein is a chromosomal mutagen. www.ncbi.nih.gov/pubmed/9729267
1999, FDA Scientists Against Soy: NIH NIEHS scientists Dr. Doerge and Dr. Sheehan have for decades consistently proven highly toxic soy-cause of multiple adverse body & brain effects, especially caused to most developmentally fragile fetus, infants, and children. www.alkalizeforhealth.net/Lsoy2.htm
2001, NIEHS Report: Dietary (soy) genistein produced effects in multiple estrogen-sensitive tissues in male and female mice consistent with estrogenic activity…...within exposure ranges in humans. www.ncbi.nlm.nih.gov/pubmed/117385181999 & 2004, Phytoestrogens are compounds found in plant foods (largely soybeans) that exhibit estrogen-like activity, and display both estrogen-like activity and anti-estrogen effects. Interindividual diversity and complexity in dietary phytoestrogen absorption and metabolism make their bioactivity unpredictable. Their actions in specific cells are determined by many factors; levels of estrogen receptor-alpha and -beta, and the diverse cocktail of co-activators and co-repressors present in any given cell type. Overall, it is naïve to assume that exposure to these compounds is always good. Inappropriate or excessive exposure to phytoestrogens may be detrimental to health. www.ncbi.nlm.nih.gov/pubmed/10548876
Soy-Cause of Multiple CANCERS:
2004, Findings suggest that oxidative DNA damage by (soy) isoflavone metabolites play a role in tumor initiation and that cell proliferation by isoflavones via Estrogen Receptors (ER) to Estrogen response elements (ERE) was largely consistent with cell proliferative activity of isoflavones. www.ncbi.nlm.nih.gov/pubmed/14992594
Leukemia: Soy-Cause of Infant Leukemia: 2010, Genistein is a bioflavonoid enriched in soy products. High levels of maternal soy consumption linked to the development of infant leukemia. Genistein induced infant leukemia. www.ncbi.nlm.nih.gov/pubmed/20638367
Maternal Diet and infant Leukemia: A Role for DNA topoisomerase II inhibitors caused to fetus in utero: 10 fold increase risk of infant acute myeloid leukemia with increased maternal consumption of DNA topo-2 inhibitor containing foods. www.ncbi.nlm.nih.gov/pubmed/9876473
(Soy is in fact an established topoisomerase II inhibitor and in fact an inhibitor of several other essential enzymes).Dietary topoisomerase II-poisons: Contribution of soy products to infant leukemia- DNA topoisomerase are nuclear enzymes inducing transient breaks in the DNA allowing DNA strands to pass through each other. Maternal exposure to low doses of dietary topoismerase II poisons, including genistein may contribute to development of infant leukemia. This study found at: excli.de/Vol1/hengstleretal02-02.pdf
Timing of phytoestrogen use is important. Recent studies have indicated that soy phytoestrogens could be contributive factors in some forms of breast cancer, penile birth defects, and infantile leukemia. Genistein might increase the risk of leukemia because it inhibits the enzyme topoisomerase which result in double strand DNA breaks which are mutagenic. Genistein may not be safe for women with estrogen-dependent breast cancer. Soy phytoestrogens or isoflavones have been definitely shown to depress thyroid function and to cause infertility in every animal species studies so far. Soy isoflavone can act like estrogen, stimulating development and maintenance of female characteristic or block cells from using cousins of estrogen. www.genistein.net/cancer.html
2007, Study demonstrates that biologically relevant concentrations of soy genistein flavonoids can induce abnormalities in mixed-linage leukemia. Particularly alarming knowing mother’s metabolism can lead to higher flavonoid concentration on fetal side. Raise public awareness and set guidelines for marketing flavonoid supplements to reduce risk of infant leukemias. www.ncbi.nlm.nih.gov/pubmed/17468513
2011, Isoflavone research revealed adverse effects on reproductive system. This is also the case with tumor-promoting effects on breast tissue. Questions about the effectiveness and safety of isoflavones have to be clarified. There are concerns about the maternal consumption of isoflavones due to the development of leukemia in infants. www.ncbi.nlm.nih.gov/pubmed/21438720
Soy-Cause of Bladder Cancer: USC Study reports soy increases risk of bladder cancer www.ncbi.nlm.nih.gov/pubmed/12496060
Colon Cancer, Gastric Cancer, & Intestinal Tumorigenesis:
2005, Soy increases colon epithelial cell proliferation measures in the sigmoid colon a common location of colon cancer. In the cecum and sigmoid colon the proliferation count increased as the serum (soy) genistein concentration increased. Cells that multiply indiscriminately can encourage the cause of colon cancer. www.ncbi.nlm.nih.gov/pubmed/16155276
2007, Maternal consumption to soy protein isolates increased the percentage of animals bearing multiple colon tumors. IGF-1 was elevated in soy protein isolate during pregnancy and casein-fed group thereafter. Elevated levels of insulin or IGF-1 are associated with increased colorectal cancer risk in humans and rodents. In summary, dietary exposure to a soy protein-based diet during pregnancy followed by the switch to casein at delivery increased colon tumor multiplicity (a measure of tumor promotion) in the male progeny as later adults. The present results raise the possibility that colon cancer, which conventionally is considered to be a cancer of the elderly, may be influenced by dietary/metabolic perturbations or programming occurring during development. joe.endocrinology-journals.org/content/195/1/79.full
2007, Soy isoflavone genisten can affect cell metabolism by specifically inhibiting protein tyrosine kinase (PTK) and/or interacting with the estrogen receptors (ERs). Synthesis of GAGs/PGs (glycosaminoglycans/proteoglycans by colon cancer cell line HT-29 cells in the presence of genistein was dependent on their type and localization which implies the active participation of the PTK interaction with ERs, which was further supported by the observed growth stimulation at low concentrations of genistein. www.ncbi.nlm.nih.gov/pubmed/18225578
2012, Soy food which is rich in isoflavones are structurally similar to 17 B-estradiol. We found an increasing trend in risk of gastric cancer associated with higher isoflavone intake among female hormone drug users. www.ncbi.nlm.nih.gov/pubmed/221703622008, ….genistein in the diet enhanced intestinal tumorigenesis in male mice. This study demonstrates that although genistein can enhance EGCG (antioxidant found in teas and many supplements) bioavailabilty this combination enhances intestinal tumorigenesis in male mice. www.ncbi.nlm.nih.gov/pubmed/18684728
2007, Several adverse effects of soy supplementation in female rats were observed. 5 of 21 rats fed soy supplement died before the end of the experiment while all animals on the control diet survived. Density of normal crypts lining the colonic mucosa was reduced, indicating gastrointestinal damage. Uterine weights, serum estradiol and serum isoflavone levels were increased in soy-supplemented diets. These adverse effects of soy isoflavones need further examination in target population of consumption of soy supplements. www.ncbi.nlm.nih.gov/pubmed/17157426
Intestinal Damage A high dose of soy genistein may potentially compromise intestinal growth. Study found at: jn.nutrition.org/content/134/6/1303Soy-Cause of Pancreatic Cancer: www.ncbi.nlm.nih.gov/pubmed/1897396

1986, Animal studies have indicated a link between pancreatic cancer and high fat and/or high protein diets as well as raw soybean consumption. Nitrosamines may also be related to pancreatic cancer. (Soy contains nitrosamines). www.ncbi.nlm.nih.gov/pubmed/3775080
Toxic Factors In Edible Legumes: Best known of the anti-nutritional factors causing nutritional stress due to toxic components found in soybeans is trypsin inhibitors that inhibit growth. Recent evidence implicates pancreatic hypertrophy as one of the main physiologic responses to trypsin inhibitors. Many legumes such as soy contain hemagglutinins also inhibit growth. Other toxic components in soybeans include goiterogenic factors, cyanogenetic glucosides, saponins and alkaloids. http://www.ajcn.org/cgi/content/abstract/11/4/281

Soy-Cause Of Breast Cancer in Women and/or Men:
2009, Environmental estrogens affect breast development in male rats: NIEHS study; Clearest evidence to date: Abnormalities which could have the potential to become cancerous developed in the mammary gland tissue of male rats that were exposed to either the soy-based phytoestrogens genistein or ethinyl estradiol- an estrogen used in birth control pills. Findings support a growing concern that exposure to low levels of estrogen….might increase the risk of breast cancer. Genistein and ethinyl estradiol exposure in multigenerational and chronic studies induce similar proliferative lesions in mammary gland. www.environmentalhealthnews.org/ehs/newscience/environmental-estrogens-affect-breast-development-in-male-rats
Similar across all generations exposed to genistein…..predominant tubuloalveolar growth in females and lobuloalveolar in males. Hyperplasia in male rats was similar induced by genistein or ethinyl estradiol…substantiate previous reports that mammary gland hyperplasia in the male rat is most sensitive markers for estrogenic endocrine disruption. www.ncbi.nlm.nih.gov/pubmed/19383540
Journal National Cancer Institute: Chemical structure of isoflavones is similar to that of estrogens, and isoflavones bind to both estrogen receptors ERa and ERb and exert estrogen-like effects. The main soybean isoflavone genistin may stimulate the growth of estrogen sensitive tumors. Research recommendation is that the impact of isoflavones on breast tissue needs to be evaluated at the cellular level in women at high risk for breast cancer. www.ncbi.nlm.nih.gov/pubmed/16985246
2008, Low concentrations of the soy phytoestrogen genistein induce Proteinase Inhibitor 9 and block killing of breast cancer cells by immune cells. A significant population consumes levels of genistein in soy products that may be high enough to induce PI-9, perhaps potentiating the survival of some preexisting breast cancer by enabling them to evade immunosurveillance. www.ncbi.nlm.nih.gov/pmc/articles/PMC2584580
2004, DNA damage by isoflavone metabolites plays a role in tumor initiation and that cell proliferation by isoflavones via estrogen receptors induces tumor promotion and or progression, resulting in cancer of estrogen-sensitive organs. www.ncib.nlm.nih.gov/pubmed/14992594
Soy-Causes Proliferation of Breast Cancer Cells:

2004, An E-screen assay revealed that genistein and daidzein enhanced proliferation of estrogen-sensitive breast cancer MCF-7 cells. www.ncbi.nlm.nih.gov/pubmed/14992594
2004, Genistein, at 1microM, stimulated the growth of MCF-7 cells and insulin-like growth Factor-I receptor pathway is involved in the proliferative effect of low-dose genistein in MCF-7 breast cancer cells. www.ncbi.nlm.nih.gov/pubmed/15126563Estrogenic properties of soy isoflavones, genistein can stimulate growth of breast cancer. www.ncbi.nlm.nih.gov/pubmed/14578162
2010, Genistein is a major isoflavone with known hormonal and tyrosine kinase-modulating activities. Genistein has been shown to promote the growth of estrogen receptor positive breast cancer cells. Breast cancer cells are particularly susceptible to the growth-promoting effects of genistein across a wide range of doses. www.ncbi.nlm.nih.gov/pubmed/20067990
Soy Blocks Anti-Estrogen Breast Cancer Drugs:
2001, Soy phytoestrogens, genistein and daidzein may stimulate existing breast tumor growth and antagonize the effects of tamoxifen. Women with current or past breast cancer should be aware of the risk of potential tumor growth when taking soy products. www.ncbi.nlm.nih.gov/pubmed/11573864

Soy Increases Risk of Diabetes: 2007, Serum insulin and leptin concentrations were decreased by soy protein isolates. (Low levels of insulin may cause of diabetes type 1. Leptin is a hormone involved in regulating appetite, body weight, fat and glucose activity. The absence of leptin leads to uncontrolled food intake and resulting obesity). joe.endocrinology-journals.org/content/195/1/79.full
2005, Findings demonstrate that genistein directly acts on pancreatic B-cells, leading to activation of the cAMP/PKA signaling cascade to exert an insulinotropic effect, providing a novel role of soy isoflavones in the regulation of insulin secretion.2004, Logistic regression analyses showed soy milk formula consumption at 4-6 and 7-12 months of age was associated with a twofold higher risk of type 1 Diabetes. www.ncbi.nlm.nih.gov/pubmed/15331209
2011, Indeed, higher soy food intake was associated with a weakly elevated diabetes risk across ethnic groups among Caucasian, Japanese American, and Native Hawaiian men and women. www.ncbi.nlm.nih.gov/pubmed/20924394
2006 Soy Genistein acutely stimulates insulin secretion in pancreatic beta-cells through cAMP-dependent protein kinase pathway. Evidence that genistein increases rapid glucose-stimulated insulin secretion in both insulin-secreting cell lines and mouse pancreatic islets. Genistein elicited a significant effect at concentration as low as 10 nmol/l. Insulinotropinic effects of genistein is primarily mediated through protein kinase A. www.ncbi.nlm.nih.gov/pubmed/16567527
2008, Soy isoflavones may influence insulin action by means of their well-known receptor-mediated estrogenic activity. Isoflavones also bind to peroxisome proliferator-activated receptors that are strongly associated with insulin action. www.ncbi.nlm.nih.gov/pubmed/1855850
2007, Results support the hypothesis that diabetes may have a role in the development of breast cancer, influencing risk via both sex hormone and insulin pathways. Our results also show that the diabetes-breast cancer association we observed only in low/intermediate soy consumers. www.ncbi.nlm.nih.gov/pubmed/17440036

Soy-Cause of Severe and Irreversible Adverse Brain Effects:
2008, Endocrine disrupting chemicals (EDCs) exert hormone-like activity and exposure to these compounds may induce both short- and long-term deleterious effects. The EDCs examined included estradiol, androgen active compounds, soy phytoestrogens, and atrazine. Effects on behavior and hypothalamic neuroendocrine systems were examined. All EDCs impaired reproduction. Several hypothalamic neural systems proved to be EDC responsive, including arginine vasotocin, catecholamines, and gonadotropin releasing hormone system. Exposure to EDCs during embryonic development has consequences beyond impaired function of the reproductive axis. Behavioral alterations reveal both direct and indirect effects of exposure to EDC. www.ncbi.nlm.nih.gov/pubmed/18006066
Soy isoflavones provide a useful model to investigate the actions of endocrine disruptors. Isoflavonoids act in vivo through both ERalpha and ERbeta. Small physiologically relevant exposure levels can alter estrogen dependent gene expression in the brain and affect complex behavior in wide range of species. www.ncbi.nlm.nih.gov/pubmed/15720476
FDA Study: “FDA Scientists Against Soy” NIH scientists Drs. Doerge and Sheehan report, “Thus during pregnancy in humans, (soy) isoflavones per se could be a risk factor for abnormal brain and reproductive tract development. Our conclusions are that no dose is without risk; the extent of risk is simply a function of dose. ….the public will be put at potential risk from soy isoflavones in soy protein, isolate without adequate warnings and information.” www.alkalizeforhealth.net/Lsoy2.htm
2001 Studies show that soybean-based formulas contain large quantities of phytoestrogens, particularly isoflavones. Because of experimental data suggesting possible deleterious effects of phytoestrogens on neuroendocrine maturation, the reduction of soy content in formulas must be considered. www.ncbi.nlm.nih.gov/pubmed/11760676
Soy phytoestrogens influence estradiol estrogenic induced mechanism results in modified brain functions: www.ncbi.nlm.nih.gov/pubmed/116026492004, Major source of endocrine disrupting substances soy derived isoflavones are most abundant and most studied are known endocrine disruptors. Isoflavones exert estrogenic and antiestrogenic properties. Soy daidzein can be metabolized to the potent equol. Equol has important ability to bind testosterone and in turn inhibits the action of androgen. Specific influence of dietary soy phytoestrogens on consumptive, learning and memory and anxiety-related behaviors is identified. www.ncbi.nlm.nih.gov/pubmed/15454683
Soya isoflavone content of rat diet can increase anxiety and stress hormone release in the male rat. Major changes in behavioral anxiety and stress hormones www.ncbi.nlm.nih.gov/pubmed/12618915
2005, Soy isoflavonoids provide a useful model to investigate the actions of endocrine disruptors. Isoflavonoids act in vivo through both ERalpha and ERbeta. Their neurobehavioural actions are largely anti-estrogenic. Small physiologically relevant exposure levels of soy isoflavonoids can alter estrogen-dependent gene expression in the brain and affect complex behavior in a wide range of species. www.ncbi.nlm.nih.gov/pubmed/15720476

Soy Damages Multiple Brain Neuro-Transmitter Systems:
2008, Endocrine disrupting chemicals (EDCs) exert hormone-like activity and exposure to these compounds may induce both short- and long-term deleterious effects. The EDCs examined included estradiol, androgen active compounds, soy phytoestrogens, and atrazine. Effects on behavior and hypothalamic neuroendocrine systems were examined. All EDCs impaired reproduction. Several hypothalamic neural systems proved to be EDC responsive, including arginine vasotocin, catecholamines, and gonadotropin releasing hormone system. Exposure to EDCs during embryonic development has consequences beyond impaired function of the reproductive axis. Behavioral alterations reveal both direct and indirect effects of exposure to EDC. www.ncbi.nlm.nih.gov/pubmed/18006066
VASOPRESSIN:
Increase vasopression; was significantly elevated in the 1250ppm genistein group consistent with known actions of estradiol and previous study the estrogenic endocrine disruptors such as genistein increase sodium preference www.ncbi.nlm.nih.gov/pubmed/12660364
Vasopressin: Soy Isoflavones form one of the main classes of phytoestrogens and exert estrogenic and anti-estrogenic effects on the central nervous system. Effects are not limited to reproductive behavior, but include effects on learning and anxiety and actions on the hypothalmic-pituitary axis. The group fed soy isoflavones 150 microg/g diet spent significantly less time in active social interaction, displayed anxiogenic effects, and had significantly elevated stress-induced corticosterone concentrations. Stress-induced plasma vasopressin concentrations were also significantly elevated. Major changes in behavioral measures of anxiety and in stress hormones can result from the soy isoflavone. These changes are as striking as those seen following drug administration. www.ncbi.nlm.nih.gov/pubmed/12618915
OXYTOCIN:
2011, Phyotestrogens have widespread effects in the adult human brain which have been previously reviewed in detail elsewhere. Genistein stimulates ER (estrogen receptor) -beta mRNA expression in the PVN, (paraventricular nucleus), an effect opposite to that of 17b estradiol. PVN is primary site of oxytocin production. ER-alpha is required for the up-regulation of oxytocin. Consumption of prepared phytoestrogen supplement attenuated estrogen-dependent upregulation of oxytocin in the rat ventromedial nucleus. www.ncbi.nlm.nih.gov/pmc/articles/PMC3074428/
Soy Inhibits GABA, A Chief Inhibitory Brain Neurotransmitter: 2007, Neurotoxic Effects of soy genistein and daidzein could be due to their inhibition of the GABA (A) receptor resulting in further enhancement of excitation by glutamate and leading to cellular damage. (GABA, Gamma-aminobutyric Acid. Inhibition of GABA can cause: anxiety disorders, panic attacks, seizure disorders, headaches, Parkinsen’s Cognitive impairment, depression, bipolar, infertility, lowers insulin levels). www.ncbi.nlm.nih.gov/pubmed?term=Genistein and daidzein induce neurotoxicity at high concentrations in primary rat neuronal cultures
2007, Soy isoflavones possess estrogen-like activity. Specifically genistein and daidzein are toxic to primary neuronal culture at high concentrations, indicating a significant cellular damage. Both genistein and daidzein increases intracellular calcium level (CA2)i, significantly. The toxic effect of soy genistein and daidzein could be due to their inhibition of the GABA(A) receptor resulting in further enhancement of excitation by glutamate and leading to cellular damage. http://ncbi.nlm.nih.gov/pubmed/17245525
2007, It is surprising that contrary to estrogen, isoflavones, specifically soy isoflavones genistein and daidzein are toxic to primary neuronal culture at high concentrations. Toxic effect of genistein and daidzein could be due to their inhibition of the GAMA(A) receptor resulting in further enhancement of excitation by glutamate and leading to cellular damage. www.ncbi.nlm.nih.gov/pubmed/17245525
Soy genistein significantly potentiated dopamine release in males. Genistein exposure may act similarly to estradiol (potent estrogen) in augmenting dopamine release. www.ncbi.nlm.nih.gov/pubmed/11836070
ZINC DEFICIENCY: Levels of estradiol of rats receiving phytoestrogens were significantly higher than control group. In abnormal levels estradiol is a dangerously potent endogenous estrogen. Soy treated group showed statistically significant decreased concentrations of zinc in blood serum. Study evidence links low zinc levels to brain disorders including autism. www.ncbi.nlm.nih.gov/pubmed/21167684
Soy Inhibits Essential Enzyme Tyrosine Kinases Related To Brain Dysfunction: 1991, Long-term potentiation (related to learning and long-term memory) in the hippocampus is blocked by tyrosine kinase inhibitors such as genistein. Tyrosine kinases participate in a kinase network with serine and threonine kinases. www.ncbi.nlm.nih.gov/pubmed/16562712
SEROTONIN: Brain cell changes are involved in the interplay between estrogen and serotonin’s effects on mood and cognition. Serotonin functions are implicated in depression, anxiety disorders, and some aspects of schizophrenia.
2003, Soy and social stress affect serotonin neurotransmission in primates. Prescribed estrogens and soy phytoestrogen increased serotonin reuptake transporter that was accompanied by increased serotonin synthesis and neuronal firing. www.ncbi.nlm.nih.gov/pubmed/12746737
Soy Increases Levels of BDNF- A family of proteins that induce the development, survival, and function of neurons. High levels contribute to seizures, epilepsy, and hyperalgesia or increase sensitivity to pain.
1999, Both estradiol and soy phytoestrogens significantly increased the mRNA levels of BDNF (brain-derived neurotrophic factor) compared to controls in the frontal cortex of female rats. www.ncbi.nlm.nih.gov/pubmed/10081916
Soy-induced neuro-degeneration. A positive correlation between tofu consumption and brain atrophy in men. Has been shown that the soy phytoestrogen genistein inhibits neuroprotetcive functions in cell cultures, recent in-vivo findings strengthen the case for possible soy –induced neurodegeneration. Genistein has been shown to suppress both DNA synthesis and the effects of brain derived neurotrophic factor (BDNF) in the hippocampus and cerebral cortex. Seems reasonable that some individuals may chose to avoid soy until proven safe …avoidance of soy also seems reasonable and should not be discouraged as alarmist. www.ncbi.nlm.nih.gov/pubmed/15142435
Calbinin D28k: Endocrine disurptors many also alter brain development by mimicry or modulation of endogenous hormone systems. Genistein treated male rats increased volume of the calbindin D28k-labeled sexually dimorphic hypothalamus. www.ncbi.nlm.nih.gov/pubmed/1546915
TOFU: 2003- Soy-induced neurodegeneration. A positive correlation between tofu consumption and brain atrophy in men. Has been shown that the soy phytoestrogen genistein inhibits neuroprotetive functions in cell cultures, recent in-vivo findings strengthen the case for possible soy –induced neurodegeneration. Genistein has been shown to suppress both DNA synthesis and the effects of brain derived neurotrophic factor (BDNF) in the hippocampus and cerebral cortex. Seems reasonable that some individuals may chose to avoid soy until proven safe …avoidance of soy also seems reasonable and should not be discouraged as alarmist. www.ncbi.nlm.nih.gov/pubmed/15142435
2008 High tofu intake is associated with worse memory in elderly Indonesian men and women. Honolulu study also reported increased risk for cognitive impairment and other dementia markers with high tofu (soybean curd) intake. www.ncbi.nlm.nih.gov/pubmed/18583909
It is a fact that several hundred published studies confirm that soy estrogenic endocrine disruptors, soy enzyme inhibitors, as well as soy's phytic acid and heavy metals, block several essential minerals proven as highly toxic to the developing brain, or adult brain. Soy hormone disruptors and anti-nutrients are repeatedly proven to disrupt, rearrange, and damage several neurotransmitter systems throughout the brain. (http://causingautism.blogspot.com).
According to 2006 Combating Autism Act, it is against the law that the HHS National Institute Of Mind Health (NIMH) and the FDA acknowledge, yet continue to conceal mass evidence that especially proves fetal, infant, and child exposure to soy's neuro-toxic components are in fact capable of causing irreversible brain disorders reported in the cause of; autism, behavioral disorders, gender chaos, homosexuality, seizures, male and female reproductive disorders, cancers, and more. The question remains: Is there a disease or disorder that soy's toxic components are proven NOT to cause?
