__________________________________________________________ What are the potential side effects of soy products? Sperm count They may lower your sperm count. Dr Jorge Chavarro from the Harvard School of Public Health found that high soya food intakes are associated with lower sperm concentration. [1] However, the Soya Protein Association refutes his article. The study on which his article is based is incomplete and does not tell the full story. The estimate of the participants' soya foods intake was only based on a questionnaire of their recall of their previous soya foods consumption. The study did not determine what other factors such as foods, medications, sexual activities or environmental factors may have directly affected the drop in sperm count. The study also did not find a negative relationship between soya and sperm mobility or sperm quality, both of which are key factors to fertility. Thyroid and reproductive functions Some studies have documented potential safety concerns on increased consumption of soy products. Impacts of soy products on thyroid and reproductive functions as well as on certain types of carcinogenesis require further study in this context. [2] |
Cognitive Impairment The Honolulu Asia Aging Study reported an increased risk for cognitive impairment and other dementia markers with high tofu (soybean curd) intake. ( Dement Geriatr Cogn Disord. 2008;26(1):50-7. Epub 2008 Jun 27.) Safety and Adverse Events A phase I double-blind clinical trial was conducted to evaluate the effects of a high oral dose of soy isoflavones administered daily for 84 days to healthy postmenopausal women. Very few adverse events occurred, and the only drug-related adverse events were mild or grade 1 in severity. CONCLUSIONS: Unconjugated soy isoflavones appear to be safe and well tolerated in healthy postmenopausal women at doses of 900 mg/day. (Menopause. 2008 Jul-Aug;15(4 Pt 1):684-92.) Uterine bleeding Abnormal uterine bleeding with endometrial pathology in three women was found to be related to a high intake of soy products. The first woman had postmenopausal bleeding with uterine polyp, proliferative endometrium and a growing leiomyoma. The second woman presented with severe dysmenorrhea, abnormal uterine bleeding, endometriosis and uterine leiomyoma not responding to treatment. The third woman with severe dysmenorrhea, abnormal uterine bleeding, endometriosis and uterine leiomyomata presented with secondary infertility. All three women improved after withdrawal of soy from their diet. {Complement Ther Clin Pract. 2008 May;14(2):132-5. Epub 2008 Mar 7C) Animal Studies in laboratory have shown that exposure to genistein causes deleterious effects on the developing female reproductive system. Neonatal treatment with genistein at environmentally relevant doses caused adverse consequences on female development which is manifested in adulthood. (Mol Nutr Food Res. 2007 Jul;51(7):832-44.) |
What soy products may benefit us? It may benefit people at risk of cardiovascular disease Epidemiological investigations suggest that soy consumption may be associated with a lower incidence of certain chronic diseases. Clinical studies also show that ingestion of soy proteins reduces the risk factors for cardiovascular disease. This led to the approval of the food-labeling health claim for soy proteins in the prevention of coronary heart disease by the U.S. FDA in 1999. [2] Similar health petitions for soy proteins have also been approved thereafter in the United Kingdom, Brazil, South Africa, the Philippines, Indonesia, Korea, and Malaysia. However, the purported health benefits are quite variable in different studies. [2] Some research has already suggested that consuming soy protein and low-fat dairy products may help lower blood pressure. In a study of 350 people with mild hypertension, the participants took the soy and milk protein supplements, their systolic blood pressure dropped by about two points, on average. [CNN.COM, July 18, 2011] It may have benefit of cholesterol lowering The Nutrition Committee of the American Heart Association has assessed 22 randomized trials conducted since 1999 and found that isolated soy protein with isoflavones (ISF) slightly decreased LDL cholesterol but had no effect on HDL cholesterol, triglycerides, lipoprotein(a), or blood pressure. The other benefits of soy consumption were not evident. [2] Soy may benefit people at risk of GI cancer Researcher at Georgia Tech found soy glucosylceramide (soy GlcCer) reduced the formation and growth of tumor cells in the gastrointestinal tracts of mice. [A Report from HealthDay, May 20, 2004] Soy may benefit people at risk of endometrial cancer Dr. Xiao Ou Shu, Vanderbilt University, TN concluded that soy may protect against endometrial cancer by comparing the soy intake of 832 women with endometrial cancer with that of 846 unaffected women. [Reuters Health, May 28, 2004] Soy may benefit people at risk of breast cancer Meta-analysis of the 8 (1 cohort, 7 case-control) studies conducted in high-soy-consuming Asians show a significant trend of decreasing risk on breast cancer with increasing soy food intake. However, soy intake was unrelated to breast cancer risk in studies conducted in the 11 low-soy-consuming Western populations whose average highest and lowest soy isoflavone intake levels were around 0.8 and 0.15 mg per day, respectively. [3] Soy may benefit people at risk of kidney diseases Using soy protein instead of animal protein reduces development of kidney disease in animals. Reducing protein intake preserves kidney function in persons with early diabetic kidney disease. Our clinical observations led us to the soy-protein hypothesis that "substitution of soy protein for animal protein results in less hyperfiltration and glomerular hypertension with resulting protection from diabetic nephropathy." These components of soy protein may lead to the benefits: specific peptides, amino acids, and isoflavones. Substituting soy protein for animal protein usually decreases hyperfiltration in diabetic subjects and may reduce urine albumin excretion.

Email received from XXXXXX@yahoo.com on Sat, 11 Oct 2008 13:53:07 -0700 (PDT) Look up the amount of side effects and health issues from these products. Look into how they are made: soy -- irradiated/biogenetically engineered abarration; and Canola from rape seed, a family of plants used for mustard gas. These are not natural; what the heck are they doing listed with vegetables on your site? LOL. Then, after you look into these and perhaps remove them from your site or list them as toxic waste, ask yourself why those products have been legitimized and to what end do the masters of those products wish that we consume them.... Again, if you can make diesel fuel with the products, if you look at how they make those products and from what, if you study how they turn blood into sludge and clog veins and arteries, you'll freak out, just as much as you'l FREAK OUT ABOUT THE TOPIC OF FLUORIDE My Reply on Sat, 11 Oct 2008 20:20:54 -0700 (PDT) I'll search if there are any new report(s) about their toxic/side effects. If you have any reference, please, forward t me. Thanks for your email. Send your comment to zhion@zhion.com |
