Genetically Engineered Soybeans May Cause Allergies

"I used to test for soy allergies all the time, but now that soy is genetically engineered, it is so dangerous that I tell people never to eat it—unless it says organic."

-Allergy specialist John Boyles, MD

 

Beginning in 1996, genes from bacteria and viruses have been forced into the DNA of soy, corn, cotton, and canola plants, which are used for food. Ohio allergist John Boyles is one of a growing number of experts who believe that these genetically modified (GM) foods are contributing to the huge jump in food allergies in the US, especially among children.

The UK is one of the few countries that conduct a yearly food allergy evaluation. In March 1999, researchers at the York Laboratory were alarmed to discover that reactions to soy had skyrocketed by 50% over the previous year.

Genetically modified soy had recently entered the UK from US imports and the soy used in the study was largely GM. John Graham, spokesman for the York laboratory, said, “We believe this raises serious new questions about the safety of GM foods."

Genetic engineering may provoke allergies

There are many ways in which the process of genetic engineering may be responsible for allergies. The classical understanding is that the imported genes produce a new protein, which may trigger reactions. This was demonstrated in the mid 1990s when soybeans were outfitted with a gene from the Brazil nut. While scientists attempted to produce a healthier soybean, they ended up with a potentially deadly one. Blood tests showed that people allergic to Brazil nuts reacted to the beans. It was never marketed.

The GM variety planted in 91% of US soy acres is called Roundup Ready—engineered to survive otherwise deadly applications of Monsanto’s Roundup herbicide. The plants contain genes from bacteria, which produce a protein that has never been part of the human food supply. Since people aren’t usually allergic to a food until they have eaten it several times, no tests can prove in advance that the protein will not cause allergies.

As a precaution, scientists compare this new protein with a database of proteins known to cause allergies. According to criteria recommended by the World Health Organization (WHO) and others, if the new GM protein contains amino acid sequences that have been shown to trigger immune responses in other proteins, the GM crop should not be commercialized (or additional testing should be done). Sections of the protein produced in GM soy, however, are identical to shrimp and dust mite allergens. But the soybean got marketed anyway.

Frighteningly, the only published human feeding study on GM foods ever conducted verified that the gene inserted into GM soy transfers into the DNA of our gut bacteria and continues to function. This means that years after we stop eating GM soy, we may still have the potentially allergenic protein continuously produced within our intestines.

Damaged soy DNA creates new (or more) allergens

The process of creating a GM crop produces massive collateral damage in the plant’s DNA. Native genes can be mutated, deleted, permanently turned on or off, and hundreds may change their levels of protein expression. This can increase existing allergen, or produce a new, unknown allergens. Both appear to have happened in GM soy.

Levels of one known soy allergen, trypsin inhibitor, were up to seven times higher in cooked GM soy compared to cooked non-GM soy. Another study discovered a unique, unexpected protein in GM soy, likely to trigger allergies.

In addition, of eight human subjects who had a skin-prick (allergy-type) reaction to GM soy, one did not also react to non-GM soy, suggesting that GM soy is uniquely dangerous.

Increased herbicides, digestive problems and allergies

Farmers use nearly double the amount of herbicide on GM soy compared to non-GM soy; higher herbicide residues might cause reactions.

GM soy reduces digestive enzymes in mice. If proteins “digest” slowly in humans, there is more time for allergic reactions (possibly to many food proteins).

Eating GM foods is gambling with our health

Documents made public from a lawsuit revealed that FDA scientists were uniformly concerned that GM foods might create hard-to-detect allergies, toxins, new diseases, and nutritional problems. Their urgent requests for required long-term feeding studies fell on deaf ears. The FDA doesn’t require a single safety test. The person in charge of that FDA policy was Monsanto’s former attorney, who later became their vice president.

Buying products that are organic or labeled non-GMO are two ways to limit your family’s risk. Another is to avoid products containing any ingredients from the seven GM food crops: soy, corn, cottonseed, canola, Hawaiian papaya, and a little bit of zucchini and crook neck squash. This means avoiding soy lecithin in chocolate, corn syrup in candies, and cottonseed or canola oil in snack foods.

Help Support GMO Labeling

The Grocery Manufacturers Association (GMA)—Monsanto’s Evil Twin—is pulling out all the stops to keep you in the dark about what’s in your food. For nearly two decades, Monsanto and corporate agribusiness have exercised near-dictatorial control over American agriculture. Finally public opinion around the biotech industry's contamination of our food supply and destruction of our environment has reached the tipping point. We're fighting back.

The insanity has gone far enough which is why I encourage you to boycott every single product owned by members of the GMA, including natural and organic brands. More than 80 percent of our support comes from individual consumers like you, who understand that real change comes from the grassroots.

Thankfully, we have organizations like the Organic Consumers Association (OCA) to fight back against these corporate giants. So please, fight for your right to know what’s in your food and help support the GMO labeling movement by making a donation today.

Together, Let's Help OCA Get The Funding They Deserve

Let’s Help OCA get the funding it deserves. I have found very few organizations who are as effective and efficient as OCA. It’s a public interest organization dedicated to promoting health justice and sustainability. A central focus of the OCA is building a healthy, equitable, and sustainable system of food production and consumption.

Please make a donation to help OCA fight for GMO labeling.
