If you were to carefully review the thousands of studies published on soy, we believe you would reach the same conclusion. The health risks associated with unfermented soy products FAR outweigh any possible benefits. However, there’s an important distinction that must be made any time you talk about soy, and that is the difference between traditionally fermented and unfermented soy products. For centuries, Asian people have been consuming fermented soy products such as natto, tempeh, and soy sauce, and enjoying the health benefits associated with them. Fermented soy does not wreak havoc on your body like unfermented soy products do.
Additionally, there’s the issue of eating genetically modified (GM) soy. In the US, over 90 percent of all soy grown is genetically modified Roundup Ready soy, which has an array of additional health hazards all of its own. Unfortunately, many Americans who are committed to healthy lifestyles have been mislead and grossly manipulated into believing that unfermented and processed soy products like soymilk, soy cheese, soy burgers and soy ice cream are health foods. As the Weston A. Price Foundation so clearly shows (below), this is far from true.
Dr. Kaayla Daniel, author of The Whole Soy Story, points out thousands of studies linking soy to malnutrition, digestive distress, immune-system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility—even cancer and heart disease. What Soy Products are Good For You? The only soy with health benefits is organic soy that has been properly fermented, and these are the only soy products I ever recommend consuming.
After a long fermentation process, the phytate and “anti-nutrient” levels of soybeans are reduced, and their beneficial properties become available to your digestive system. The primary fermented soy products I recommend are:
•Tempeh a fermented soybean cake with a firm texture and nutty, mushroom-like flavor
•Miso, a fermented soybean paste with a salty, buttery texture (commonly used in miso soup).
•Natto, fermented soybeans with a sticky texture and strong, cheese-like flavor.
•Soy sauce, which is traditionally made by fermenting soybeans, salt and enzymes; be wary because many varieties on the market today are made artificially using a chemical process.
Please note that tofu is NOT on this list. Tofu is not fermented, and is therefore not among the soy foods recommend. The Weston A. Price Foundation has compiled a list of soy dangers and myths to get the truth out once and for all. ( By Dr. J. Mercola from www.mercola.com )
MYTHS AND TRUTHS ABOUT SOY:
Myth: Use of soy as a food dates back many thousands of years.
Truth: Soy was first used as a food during the late Chou dynasty (1134-246 BC), only after the Chinese learned to ferment soybeans to make foods like tempeh, natto and tamari.
Myth: Asians consume large amounts of soy foods.
Truth: Average consumption of soy foods in Japan and China is 10 grams (about 2 teaspoons) per day. Asians consume soy foods in small amounts as a condiment, and not as a replacement for animal foods.
Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods.
Truth: Most modern soy foods are not fermented to neutralize toxins in soybeans, and are processed in a way that denatures proteins and increases levels of carcinogens.
Myth: Soy foods provide complete protein.
Truth: Like all legumes, soybeans are deficient in sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine.
Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets.
Truth: The compound that resembles vitamin B12 in soy cannot be used by the human body: in fact, soy foods cause the body to require more B12
Myth: Soy formula is safe for infants.
Truth: Soy foods contain trypsin inhibitors that inhibit protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted growth and pancreatic disorders. Soy foods increase the body’s requirement for vitamin D, needed for strong bones and normal growth. Phytic acid in soy foods results in reduced bioavailabilty of iron and zinc, which are required for the health and development of the brain and nervous system. Soy also lacks cholesterol, likewise essential for the development of the brain and nervous system. Megadoses of phytoestrogens in soy formula have been implicated in the current trend toward increasingly premature sexual development in girls and delayed or retarded sexual development in boys.
Myth: Soy foods can prevent osteoporosis.
Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths and vitamin D from seafood, lard and organ meats prevent osteoporosis in Asian countries—not soy foods.
Myth: Modern soy foods protect against many types of cancer.
Truth: A British government report concluded that there is little evidence that soy foods protect against breast cancer or any other forms of cancer. In fact, soy foods may result in an increased risk of cancer.
Myth: Soy foods protect against heart disease.
Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol with soy protein improves one’s risk of having heart disease.
Myth: Soy estrogens (isoflavones) are good for you.
Truth: Soy isoflavones are phyto-endocrine disrupters. At dietary levels, they can prevent ovulation and stimulate the growth of cancer cells. Eating as little as 30 grams (about 4 tablespoons) of soy per day can result in hypothyroidism with symptoms of lethargy, constipation, weight gain and fatigue.
Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years.
Truth: Soy foods can stimulate the growth of estrogenic-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause.
Myth: Phytoestrogens in soy foods can enhance mental ability.
Truth: A recent study found that women with the highest levels of estrogen in their blood had the lowest levels of cognitive function; In Japanese Americans tofu consumption in mid-life is associated with the occurrence of Alzheimer’s disease in later life.
Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status.
Truth: Archer Daniels Midland (ADM) recently withdrew its application to the FDA for GRAS status for soy isoflavones following an outpouring of protest from the scientific community. The FDA never approved GRAS status for soy protein isolate because of concern regarding the presence of toxins and carcinogens in processed soy.
Myth: Soy foods are good for your sex life.
Truth: Numerous animal studies show that soy foods cause infertility in animals. Soy consumption enhances hair growth in middle-aged men, indicating lowered testosterone levels.
Myth: Soybeans are good for the environment.
Truth: Most soybeans grown in the US are genetically engineered to allow farmers to use large amounts of herbicides.
Myth: Soybeans are good for developing nations.
Truth: In third-world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations.
