"A great piece about soy. Through my many years of research of health and nutrition I have never come across any real science that states or confirms the many myths of the dangers of soy. This misleading information written by two women has spread like wild fire across the internet over the years creating much confusion and fear about this bean, and even health advisors have succumbed into believing this vegetable is deadly without looking further into the source of the information or evidence (or lack thereof) to support the claims. This is a basic article which highlights the many myths but is a good place to start to become informed if soy is a concern for you. As with all health claims - do your research. Who is saying what? What is their agenda? What of the peer reviewed studies? Who is behind/backing the studies? I believe in eating whole foods, and supplementing your diet with processed soy foods is not a healthy choice. Like all processed foods processed soy protein can be harmful in many number of ways - you do not need science to tell you that!! I will try and post more info on this matter. Good reading, and good health!"
The Whole Soy Story? Half Truths and Untruths Do Not A Whole Story Make
"While the vast majority of studies of soy and health are neutral or positive, it has to be said that a small proportion of weak, preliminary or otherwise inconclusive studies suggest soy may increase the risk of other health disorders...I know that sounds scary, but... Even scarier is a health book that persistently misleads and manipulates readers while pretending to enlighten them."
"Despite the abundance of scientific evidence demonstrating the benefits of whole soy foods, many people have been scared off from healthful foods like edamame by anti-soy propaganda (lacking responsible scientific integrity) that continues to float around the internet."
"Despite how ubiquitous soy and its derivatives have become in our diets, confusion persists... That's why we're setting the record straight on some of the biggest soy myths that just won't go away. Here are a few biggies to stop believing, stat."
"The anti-soy crusade has needlessly frightened many away from a food source that has long been a boon to humankind, a food source that can, if we are respectful of our bodies and of nature, nourish and bless us in countless ways."
"Evidence to date is reassuring. Soy products may reduce the risk of breast cancer and breast cancer recurrence. They do not appear to have adverse effects on male hormone function or on the thyroid gland, but may reduce the absorption of thyroid medications"
"About 75 percent of breast cancer tumors have estrogen receptors, meaning they grow in response to estrogen. And so, if breast cancer runs in your family, it stands to reason that you'd want to closely regulate exposure to a hormone that promotes tumor growth. For many people, doing so includes avoiding soy -- but luckily for those who love their edamame or veggie burgers, this isn't necessary at all."
Soy Consumption Associated with Improved Survival and Lower Recurrence Rates in Breast Cancer Patients
Association between Soy Isoflavone Intake and Breast Cancer Risk for Pre- and Post-Menopausal Women: A Meta-Analysis of Epidemiological Studies
"Soy isoflavone intake could lower the risk of breast cancer for both pre- and post-menopausal women in Asian countries. For women in Western countries, pre- or post-menopausal, there is no evidence to suggest an association between intake of soy isoflavone and breast cancer."
"Even though animal studies have shown mixed effects on breast cancer with soy supplements, studies in humans have not shown harm from eating soy foods. Moderate consumption of soy foods appears safe for both breast cancer survivors and the general population, and may even lower breast cancer risk"
Case-Control Study of Phyto-Oestrogens and Breast Cancer
"Phyto-oestrogens are a group of naturally occurring chemicals derived from plants; they have a structure similar to oestrogen, and form part of our diet...There is a substantial reduction in breast-cancer risk among women with a high intake (as measured by excretion) of phyto-oestrogens-particularly the isoflavonic phyto-oestrogen equol and the lignan enterolactone. These findings could be important in the prevention of breast cancer."
"Soyfoods are unique among commonly-consumed foods because they contain large amounts of isoflavones. And in order to understand the controversy around soyfoods, it’s necessary to understand what isoflavones are—and why they aren’t the same as estrogen. Sometimes referred to as phytoestrogens, isoflavones have a chemical structure that is very similar to the hormone estrogen, but small variations in their structure translate to important differences in physiological effects."
Soy Phytoestrogens, Osteoporosis and Menopausal Women
"Osteoporosis is the gradual declining in bone mass with age, leading to increased bone fragility and fractures... In view of beneficial effect of soy protein on bone metabolism indicators, inclusion of this relatively inexpensive food in the daily diet of menopausal women, will probably delay bone resorption, thereby preventing osteoporosis."
"Epidemiologic studies have shown that the consumption of soy foods may be associated with a reduction in cancer risk in humans... The results of this analysis suggest that consumption of soy foods is associated with a reduction in prostate cancer risk in men. This protection may be associated with the type and quantity of soy foods consumed."
Phytoestrogen: Foods High in Phytoestrogens and Health Benefits
"Phytoestrogens are estrogen hormone-like chemicals found in plants... Several studies associate phytoestrogens with reduced risks of breast cancer, prostate cancer and cardiovascular diseases. Other phytoestrogen health benefits are reduced osteoporosis (bone loss) and menopausal symptoms. Both flavonoid and lignan phytoestrogens also have antioxidant activity."
FALSE: Soy Inhibits the Digestion of Nutrients (Anti-Nutrients)
"Claims that unfermented soy foods (such as tofu and soy milk) contain toxins that block the action of enzymes needed to digest protein, and that these toxins cause pancreatic enlargement, cancer and stunted growth in animals are misleading. While soy does contain substances (trypsin inhibitors) that may adversely affect the pancreas in animals, there's no solid evidence that they cause similar problems in humans. Furthermore, trypsin inhibitors are found in all of the vegetables of the cabbage family as well as in beans other than soy."

Soy: A Complete Source of Protein
"Soybeans contain all of the essential amino acids necessary for human nutrition and have been grown and harvested for thousands of years. Populations with diets high in soy protein and low in animal protein have lower risks of prostate and breast cancers than other populations. Increasing dietary whole soy protein lowers levels of total cholesterol, low-density lipoproteins, and triglycerides; may improve menopausal hot flashes; and may help maintain bone density and decrease fractures in postmenopausal women."
Enjoy Soy: Plant Protein Complete With All 9 Essential Amino Acids
"Soy is a nutrient-rich plant protein complete with all nine essential amino acids, which makes it unique to other plant protein sources. Soybeans are a good source of fiber, vitamins, and minerals, including folate, selenium, potassium and magnesium. They also contain antioxidants and phytochemicals, including isoflavones, phenolic acids and sapanonins, and are the only bean containing omega 3-fatty acids. Over the years, however, soy has been subject to debate."
