Soy has long been recognized as a nutrient-dense food and as an excellent source of protein by respected dietitians and clinical nutritionists. The soybean contains all of the essential amino acids, as well as an impressive list of micronutrients (vitamins and minerals). Micronutrients in rich supply in soy include: calcium, iron, magnesium, manganese, phosphorus, potassium, vitamins B1, B2, B3, B5, B6, B9, C and zinc. Fiber and omega-3 and 6 fatty acids are also present in soy. The composition of these nutrients varies among preparations, but is in the highest quantity in whole soy foods such as edamame (whole soy beans), soy milk, tofu and tempeh.
Yet despite the powerful health benefits of whole soy foods, myths and misinformation regarding the ‘dangers’ of soy consumption are being widely circulated and presented as fact. I will address a few of these myths by taking a closer look at some of the sources of confusion and controversy.
“All soy is GMO!”
I would like to begin by explaining that the largest consumer of commercially grown GMO soybeans, both in the US and globally, is farmed animals. GMOs are genetically modified organisms, and their safety for human consumption is a hot topic of debate; many European countries have banned GMOs. While long term studies and conclusive data on the health effects of GMOs are lacking, GMOs are ubiquitous in our food supply. Soybeans are one of several major food staples now dominated by genetic modification. Currently, 81% of the global soybean crop is genetically modified, and approximately 85% of all GMO soybeans
