It wasn't quite Spring in 2010. I had had a recurring cold all winter and couldn't seem to get rid of it for longer than two weeks. Finally, my body had enough and I became severely ill, coughing up alarming amounts of blood. It took doctors weeks to figure out what was causing my lungs to bleed. I was self-destructing. I had p-ANCA vasculitis, a rare autoimmune disease that causes, in my case, antibodies to attack the blood vessels in my lungs. After an internal battle that took me to the intensive care unit by life-flight to the regional hospital and nearly two weeks of unconsciousness, my life was spared with the help of hefty drugs and lots of machines. There I laid wondering, what sparks autoimmune diseases to wreak such havoc? Little did I know that genetically-modified foods play a part in cases like mine.

Before my encounter with p-ANCA vasculitis, I had a pretty care-free life. It didn't matter to me what foods I ate, as long as they tasted good. I led a pretty active lifestyle, in fact, I was ascending up a mountain bike trail when my bloody cough became severe. I really didn't even know what autoimmune diseases were or how they affect us. Autoimmune diseases are unlike any other disease because the immune system becomes confused and attacks parts of one's own body, mistaking the body's tissue for a foreign invader.
According to research by medical author Donna Jackson Nakazawa, autoimmune diseases have been on the rise for the last forty years. Most common conditions include type 1 diabetes, multiple sclerosis, celiac, fibromyalgia, psoriases, and lupus and there are more than eighty known types of autoimmune diseases. And the rates of these conditions keep rising. Lupus and multiple sclerosis have nearly tripled over the past four decades. Type 1 diabetes has increased during the same time period. Approximately one in twelve Americans have an autoimmune disease (Nakazawa, 2008). Traditional medicine really can't pinpoint the cause for this epidemic of autoimmune disorders, but this dramatic increase over such a short period of time must be caused by things other than heredity. Virginia T. Ladd, President and Executive Director of the American Autoimmune Related Diseases Association said, “With the rapid increase in autoimmune diseases, it clearly suggests that environmental factors are at play due to the significant increase in these diseases. Genes do not change in such a short period of time.” (Rattue, 2012).
Despite the lack of concrete causes that trigger autoimmune diseases, there is evidence that food allergies could be the culprit. I'm not talking about IgE-mediated allergies where you eat seafood or peanuts and your throat swells shut or you break out in hives, but a much less-noticeable battle going on in your digestive tract. Hidden food allergens reduce the digestive system's ability to absorb nutrients of certain foods, leaving them undigested. Undigested food particles can leak through the wall of the intestines, becoming foreign invaders that the immune system creates antibodies to attack. This sparks inflammation in our bodies, weakening our immunity. Prolonged exposure to these allergens confuses our immune systems, so that they attack us instead of the offending food, resulting in an autoimmune disease (Lopez, 2007).
So how do genetically-modified foods affect our bodies? In GMOs, the DNA that is being inserted into the target organism's genes is from a completely different species, often from bacteria, animals, and humans. This creates a transgenic organism. These species wouldn't usually mate or have offspring together. Jeffrey Smith, an expert in GMOs, explains why this is a problem: “The process of genetic engineering can cause hundreds or thousands of mutations up and down the DNA and up to 5 percent of the existing natural genes can change their levels of expression. And these are not evaluated in the superficial studies that are being done before the crops get on the market as food,” (Phillips, 2012). Now the problems that can occur with these new organisms are health issues caused by unknown allergies from things that normally wouldn't have to be tested for because humans naturally wouldn't be consuming them. Do you think that you would like to know which of your foods are made with GMOs?
Proponents for GMOs argue that humans have been genetically altering our crops for thousands of years, since the beginning of agriculture. But there is a difference between cross-breeding and genetic engineering. Cross-breeding is natural and produces traits without any lab experiments. Genetic engineering has begun within the last 20 years and has minimal safety studies on its impacts upon our health and the environment.

GMO producers also claim that GMOs help to reduce world hunger. Due to modern agriculture, we produce much more food than we need. So it's not the lack of food that is causing world hunger, but limited access to it. GMOs like Golden Rice, which was bioengineered to contain beta-carotene, helps the human body produce Vitamin A. But the very countries that need these foods the most are also the ones that can't afford the additional irrigation systems and fertilizer that these crops require to grow properly (Robbins, 2011). Also, Monsanto and other biotech companies patent their seeds and use what they call a “Technology Protection System” - their crops produce seeds that are sterile, preventing farmers from saving some from the harvest and planting them for next year's crop. These “suicide seeds” keep customers coming back year after year to get the desired seeds. Will GMOs really help end world hunger?
Are GMO crops better for the environment and do they pose a more sustainable way to grow than traditional crops? Proponents of GMOs claim that because GMOs are engineered for resistance to insects and weeds, they require less insecticides and herbicides. But Monsanto's “Roundup Ready” seeds are engineered with chemicals in them so when the herbicide Roundup is sprayed on the fields, the crops survive and the weeds die from the toxic chemicals. Unfortunately, we are now seeing super-weeds developing greater resistance to Roundup and other herbicides and more toxic levels of herbicides are being used. Bt (Bacillus thuringiensis) crops are engineered to contain a bacterial gene that kills insects when eaten. Again, we are seeing super-bugs evolve with resistance to Bt (GM Crops).
