Soy - myths and truths - Historian - 05-17-2006

<B><FONT face="Georgia, Times New Roman, Times, Serif">Revealing the myths and truths about soy </FONT></B> <FONT face="Georgia, Times New Roman, Times, Serif"></FONT> <FONT face="Georgia, Times New Roman, Times, Serif">by the Weston A. Price Foundation </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Due to the acceleration of the adulteration of animal sources of protein, including those labeled "organic," it is important to make sure our readers know that soybeans, which are listed as an ingredient on a variety of processed food product labels, are not a viable source of protein. It is interesting to note that the famous vegan herbalists and naturopaths in recent history never advocated the use of soybeans as a source of dietary protein. Since we have had many requests for a lucid dissertation on soy and its known risks while witnessing many of our associates using soy products, we felt this information is extremely timely. Many people do not do well on a strictly vegan vegetarian diet and need access to unadulterated sources of animal protein. The Weston A. Price Foundation is an invaluable source of accurate information and is a credible advocacy organization for the health benefits of raw, unadulterated dairy products, grass fed beef and natural husbandry practices.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Use of soy as a food dates back many thousands of years.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: Soy was first used as a food during the late Chou dynasty (1134-246 BC), only after the Chinese learned to ferment soy beans to make foods like tempeh, natto and tamari. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Asians consume large amounts of soy foods. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy foods provide complete protein. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: Like all legumes, soy beans are deficient in the sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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 </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy formula is safe for infants. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy foods can prevent osteoporosis. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Modern soy foods protect against many types of cancer. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy foods protect against heart disease. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol improves one’s risk of having heart disease. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy estrogens (isoflavones) are good for you. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: Soy foods can stimulate the growth of estrogen-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Phytoestrogens in soy foods can enhance mental ability. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy foods are good for your sex life. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">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. Japanese housewives feed tofu to their husbands frequently when they want to reduce their virility. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy beans are good for the environment. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: Most soy beans grown in the U.S. are genetically engineered to allow farmers to use large amounts of herbicides. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Myth: Soy beans are good for developing nations. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Truth: In third world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Soy Dangers Summarized</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">High levels of phytic acid in soy reduce assimilation of calcium, magnesium, copper, iron and zinc. Phytic acid in soy is not neutralized by ordinary preparation methods such as soaking, sprouting and long, slow cooking. High phytate diets have caused growth problems in children. </FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders. In test animals, soy containing trypsin inhibitors caused stunted growth.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Soy phytoestrogens are potent antithyroid agents that cause hypothyroidism and may cause thyroid cancer. In infants, consumption of soy formula has been linked to autoimmune thyroid disease.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Vitamin B12 analogs in soy are not absorbed and actually increase the body’s requirement for B12.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Soy foods increase the body’s requirement for vitamin D. Toxic synthetic vitamin D is added to soy milk.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Fragile proteins are over-denatured during high temperature processing to make soy protein isolate and textured vegetable protein.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Processing of soy protein results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Free glutamic acid or MSG, a potent neurotoxin, is formed during soy food processing and additional amounts are added to many soy foods.</FONT>
<FONT face="Georgia, Times New Roman, Times, Serif">Soy foods contain high levels of aluminum which is toxic to the nervous system and the kidneys.</FONT>
