Corn? Not so much. Most Americans simply do not understand that 80% of non-organic supermarket processed foods (basically every product containing soy, corn, canola, cottonseed oil, sugar beet derivatives or ingredients from animals fed soy or corn) are contaminated with genetically modified organisms. While nearly everyone in North America has eaten genetically modified foods, only 26% believe that they have.
People don't think they're eating genetically modified foods because they have no way of knowing whether they are or not. Genetically modified foods aren't labeled.
Gen-M, "Generation Monsanto," the first generation of humans force-fed genetically modified foods, hasn't reached reproductive age yet (they were born in the late 1990s). But, if a critical mass of animal feeding studies are any indication, the millennial generation, reared on Food Inc.'s unlabeled "Frankenfoods" can look forward to a long-term epidemic of cancer, food allergies, sterility, learning disabilities, and birth defects.
