One
of the
biggest controversies
surrounding food in recent years
is the entry of genetically modified
organisms (GMOs) into our food system. If you don’t know about GMOs by now, here’s the concept in a nutshell: Genetically modified foods have had their DNA changed through genetic engineering, using advanced techniques to insert foreign genes (from such varied sources as bacteria and viruses) in order to enhance or change certain characteristics of the organism. The most common modified foods are derived from plants such as soybean, corn, canola, and cotton, but the list of GMOs also includes hormones given to dairy cattle (rbGH). Now even the animals themselves are being genetically engineered.

Supporters of genetic engineering say that modification of organisms on a genetic level is safe, and is similar to how conventional plant breeding has taken place for thousands of years. They also state that in order to gain efficiency in food production to feed the world, GM foods are necessary. The producers of these GMOs maintain that they are as safe as any other food, and have no negative effect on the people consuming them or the environment.
GMOs and the intermingling of foods in our food system during harvest, storage, and processing, most U.S. consumers have been eating genetically modified foods for years. Even those of us who focus on eating all organic probably have been ingesting these foods if we eat out or dine at someone’s house who isn’t as strict as we are with their food purchases. Some 60 to 70% of the products in a grocery store contain some type of genetically engineered ingredient, with the biggest offenders being soy, corn, canola oil, and cottonseed oil.
seeds increases crop yields and decreases the use of pesticides and herbicides for food production (hence the claim that GMOs will help feed the world). However, contrary to the information coming from the supporters of genetic engineering, studies have shown that just as many pesticides and herbicides are being applied to GM crops as non-GM crops, and in some cases at even higher quantities. For crops modified to be resistant to herbicides, farmers can spray even heavier without damaging the plants, leading to increased use of herbicides worldwide. These herbicides end up in our groundwater, and may also be present in food even after harvest and processing. A recent study sponsored by the Committee for Independent Research and Information on Genetic Engineering (CRIIGEN), published in Chemical Research in Toxicology journal, found that Roundup (glyphosate) diluted 105 times was toxic to three different human cell types. This level is significantly lower than the currently accepted residue levels. What this means is that every bite of GM food (modified to be tolerant of glyphosate application) will
