Vegetarians aren't the only ones who should be concerned; there's soy in just about everything you eat these days -- including hamburgers, mac 'n cheese and salad dressing.

Soy is a lucrative industry. According to Soyfoods Association of North America, from 1992 to 2008, sales of soy foods have increased from $300 million to $4 billion. From sales numbers to medical endorsements, it would seem that soy has reached a kind of miracle food status.

But soy's glory days may be coming to an end. New research is questioning its health benefits and even pointing out some potential risks. Although definitive evidence may be many years down the road, the American Heart Association has quietly withdrawn its support. And some groups are waging an all-out war, warning that soy can lead to certain kinds of cancers, lowered testosterone levels, and early-onset puberty in girls.
Most of the soy eaten today is also genetically modified, which may pose another set of health risks. The environmental implications of soy production, including massive deforestation, increased use of pesticides and threats to water and soil, are providing more fodder for soy's detractors.
All of this has many people wondering if they should even be eating it at all. And you are most likely eating it. Even if you're not a vegetarian or an avid tofu fan, there is a good chance you're still eating soy. Raj Patel, author of Stuffed and Starved, explains that soy is now an ingredient in three-quarters of processed food on the market and just about everything you'd find in a fast food restaurant. It's used as filler in hamburgers, as vegetable oil and an emulsifier. It's in salad dressing, macaroni and cheese, and chicken nuggets.
"Even if you read every label and avoid cardboard boxes, you are likely to find soy in your supplements and vitamins (look out for vitamin E derived from soy oil), in foods such as canned tuna, soups, sauces, breads, meats (injected under poultry skin), and chocolate, and in pet food and body-care products," wrote Mary Vance for Terrain Magazine. "It hides in tofu dogs under aliases such as textured vegetable protein, hydrolyzed vegetable protein, and lecithin--which is troubling, since the processing required to hydrolyze soy protein into vegetable protein produces excitotoxins such as glutamate (think MSG) and aspartate (a component of aspartame), which cause brain-cell death."
(good grief!)

There is also a risk of breast and other reproductive cancers for women and the potential for testicular and infertility in men.
While there was much news about the American Heart Association endorsing soy in 2000, there was little attention given when the AHA changed its mind and quietly withdrew its pro-soy claims in 2006, O'Brien points out. She also learned that they were not the only ones who expressed concerned about soy. A study in the British medical journal Lancet in 1996 warned of the effects of soy in infant formula. The study found babies had levels of isoflavones that were five to 10 times higher than women taking soy supplements for menopause. The effects in girls could be early-onset puberty, obesity, breast and reproductive cancers. Boys could face testicular cancer, undescended testicles and infertility. Additionally, O'Brien says, a 2003 British study conducted by Gideon Lack of St. Mary's Hospital at Imperial College London followed 14,000 children from the womb through age 6 and found that kids who had been given soy formula as infants seemed almost three times as likely to develop a peanut allergy later on.
As if all this weren't disturbing enough, there's also another reason to be alarmed -- most of the soy we eat is genetically modified to withstand increasing doses of weed-killing herbicides, and really, we have no idea what the long-term affects of that might be. So, what's a person to do? Stay away from soy as much as possible, which also means avoiding processed foods. And, even if we choose not to eat those things, some of us may end up getting them anyway. "There are different sales channels that these companies are using to sell soy with little regard for the cost to people down the road," said O'Brien. "Soy that is not used in grocery stores, in restaurants, or consumed by livestock, is disposed of in school lunch programs, hospitals, and prisons."

One organization, the Weston A. Price Foundation, is actually engaged in a lawsuit on behalf of Illinois state prisoners who say they're eating a diet made of largely soy protein. "In their letters, the prisoners have described deliberate indifference to a myriad of serious health problems caused by the large amounts of soy in the diet," the WAP Foundation writes. "Complaints include chronic and painful constipation alternating with debilitating diarrhea, vomiting after eating, sharp pains in the digestive tract after consuming soy, passing out after soy-based meals, heart palpitations, rashes, acne, insomnia, panic attacks, depression and symptoms of hypothyroidism, such as low body temperature (feeling cold all the time), brain fog, fatigue, weight gain, frequent infections and an enlarged thyroid gland."

There are even some soy and biofuel plantations in Brazil where the International Labor Organization says there are 40,000 slaves working today. Slaves! In Brazil, producing biofuels and soy."
