The Truth About Soy

As many of you know, I am not a fan of soy (or more accurately UNFERMENTED SOY). I believe it should be avoided by all those with Thyroid issues, history of any cancers, and males in general. After reading this article from The Weston A. Price Foundation, I thought it merited reposting it here.
They  compiled a list of soy dangers and myths to get the truth out once and for all. Again, I just want to stress that they are referring to UNFERMENTED soy. I will post some top reasons why SOY is a 'risky' food to eat on Thursday. What are your thoughts on soy??




Soy Dangers Summarized

•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, but only with long fermentation. High-phytate diets have caused growth problems in children.

•Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders. In test animals, soy containing trypsin inhibitors caused stunted growth.

•Soy phytoestrogens disrupt endocrine function and have the potential to cause infertility and to promote breast cancer in adult women.

•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.

•Vitamin B12 analogs in soy are not absorbed and actually increase the body's requirement for B12.

•Soy foods increase the body's requirement for Vitamin D. Toxic synthetic Vitamin D2 is added to soy milk.

•Fragile proteins are over-denatured during high temperature processing to make soy protein isolate and textured vegetable protein.

•Processing of soy protein results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines.

•Free glutamic acid or MSG, a potent neurotoxin, is formed during soy food processing and additional amounts are added to many soy foods to mask soy's unpleasant taste.

•Soy foods contain high levels of aluminum, which is toxic to the nervous system and the kidneys.

Myths and Truths About Soy

Here we dispel the myths of the "Diet Dictocrats" and reveal the scientific validity behind our wise ancestors' nutrient-dense diets.



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 estrogen-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.



Soy Infant Formula: Birth Control Pills for Babies

Babies fed soy-based formula have 13,000 to 22,000 times more estrogen compounds in their blood than babies fed milk-based formula. Infants exclusively fed soy formula receive the estrogenic equivalent of at least four birth control pills per day.



Male infants undergo a testosterone surge during the first few months of life, when testosterone levels may be as high as those of an adult male. During this period, baby boys are programmed to express male characteristics after puberty, not only in the development of their sexual organs and other masculinity traits, but also in setting patterns in the brain characteristic of male behavior.



In animals, studies indicate that phytoestrogens in soy are powerful endocrine disrupters. Soy infant feeding -- which floods the bloodstream with female hormones that inhibit testosterone -- cannot be ignored as a possible cause of disrupted development patterns in boys, including learning disabilities and attention deficit disorder.



Male children exposed to DES, a synthetic estrogen, had testes smaller than normal on maturation and infant marmoset monkeys fed soy isoflavones had a reduction in testosterone levels up to 70 percent compared to milk-fed controls.



Almost 15 percent of white girls and 50 percent of African-Americans girls show signs of puberty, such as breast development and pubic hair, before the age of eight. Some girls are showing sexual development before the age of three. Premature development of girls has been linked to the use of soy formula and exposure to environmental estrogen-mimickers such as PCBs and DDE.



Intake of phytoestrogens even at moderate levels during pregnancy can have adverse affects on the developing fetus and the timing of puberty later in life.


Here is just a sampling of the health effects that have been linked to soy consumption:




•Breast cancer

•Brain damage

•Infant abnormalities

•Thyroid disorders

•Kidney stones

•Immune system impairment

•Severe, potentially fatal food allergies

•Impaired fertility

•Danger during pregnancy and nursing

Soy proponents will argue that soy-based foods (they lump the fermented ones with the unfermented) will protect you from everything from colon, prostate and breast cancer to strokes, osteoporosis, and asthma.



But said enthusiasts never mention the studies that illuminate soy’s downside and all of the dangers posed to your health, which are based on sound research.



Another unfortunate fact is that 80 percent of the world’s soy is used in farm animal feed, which is why soy production is contributing to deforestation. Some soy propagandists have suggested that the solution to this is for all of us to become vegetarians—a reckless recommendation rooted in total ignorance about nutrition—whereas a far better solution is a major overhaul in how farm animals are fed and raised.
