The only published human feeding study revealed what may be the most dangerous problem from GM foods. The gene inserted into GM soy transfers into the DNA of bacteria living inside our intestines and continues to function. [xxvi] This means that long after we stop eating GMOs, we may still have potentially harmful GM proteins produced continuously inside of us. Put more plainly, eating a corn chip produced from Bt corn might transform our intestinal bacteria into living pesticide factories, possibly for the rest of our lives.
When evidence of gene transfer is reported at medical conferences around the US, doctors often respond by citing the huge increase of gastrointestinal problems among their patients over the last decade. GM foods might be colonizing the gut flora of North Americans.
Warnings by government scientists ignored and denied
Scientists at the Food and Drug Administration (FDA) had warned about all these problems even in the early 1990s. According to documents released from a lawsuit, the scientific consensus at the agency was that GM foods were inherently dangerous, and might create hard-to-detect allergies, poisons, gene transfer to gut bacteria, new diseases, and nutritional problems. They urged their superiors to require rigorous long-term tests. [xxvii] But the White House had ordered the agency to promote biotechnology and the FDA responded by recruiting Michael Taylor, Monsanto's former attorney, to head up the formation of GMO policy. That policy, which is in effect today, denies knowledge of scientists' concerns and declares that no safety studies on GMOs are required. It is up to Monsanto and the other biotech companies to determine if their foods are safe. Mr. Taylor later became Monsanto's vice president.
Dangerously few studies, untraceable diseases
AAEM states, "GM foods have not been properly tested" and "pose a serious health risk." Not a single human clinical trial on GMOs has been published. A 2007 review of published scientific literature on the "potential toxic effects/health risks of GM plants" revealed "that experimental data are very scarce." The author concludes his review by asking, "Where is the scientific evidence showing that GM plants/food are toxicologically safe, as assumed by the biotechnology companies?"[xxviii]
Famed Canadian geneticist David Suzuki answers, "The experiments simply haven't been done and we now have become the guinea pigs." He adds, "Anyone that says, 'Oh, we know that this is perfectly safe,' I say is either unbelievably stupid or deliberately lying."[xxix]
Dr. Schubert points out, "If there are problems, we will probably never know because the cause will not be traceable and many diseases take a very long time to develop." If GMOs happen to cause immediate and acute symptoms with a unique signature, perhaps then we might have a chance to trace the cause.
This is precisely what happened during a US epidemic in the late 1980s. The disease was fast acting, deadly, and caused a unique measurable change in the blood-but it still took more than four years to identify that an epidemic was even occurring. By then it had killed about 100 Americans and caused 5,000-10,000 people to fall sick or become permanently disabled. It was caused by a genetically engineered brand of a food supplement called L-tryptophan.
If other GM foods are contributing to the rise of autism, obesity, diabetes, asthma, cancer, heart disease, allergies, reproductive problems, or any other common health problem now plaguing Americans, we may never know. In fact, since animals fed GMOs had such a wide variety of problems, susceptible people may react to GM food with multiple symptoms. It is therefore telling that in the first nine years after the large scale introduction of GM crops in 1996, the incidence of people with three or more chronic diseases nearly doubled, from 7% to 13%. [xxx]
To help identify if GMOs are causing harm, the AAEM asks their "members, the medical community, and the independent scientific community to gather case studies potentially related to GM food consumption and health effects, begin epidemiological research to investigate the role of GM foods on human health, and conduct safe methods of determining the effect of GM foods on human health."
Citizens need not wait for the results before taking the doctors advice to avoid GM foods. People can stay away from anything with soy or corn derivatives, cottonseed and canola oil, and sugar from GM sugar beets-unless it says organic or "non-GMO." There is a pocket Non-GMO Shopping Guide, co-produced by the Institute for Responsible Technology and the Center for Food Safety, which is available as a download, as well as in natural food stores and in many doctors' offices.
If even a small percentage of people choose non-GMO brands, the food industry will likely respond as they did in Europe-by removing all GM ingredients. Thus, AAEM's non-GMO prescription may be a watershed for the US food supply.
