If you are not petrified of eating non-organic corn after reading the attached article then I don't know what would scare you. Most corn on the market is genetically modified. I believe the number is around 85% of corn. The only way you can guarantee not eating genetically modified products is to buy organic. I only buy organic corn, even popcorn. My only exception was going to the theater but after finding out about the results of the French study in which guinea pigs grew huge tumors (see below) after being fed a lifetime of GM corn, I won't be buying popcorn at the theater either. By the way, a majority of soy (~70%)on the market is genetically modified also. You should never buy corn or soy that is not organic if you care about your health. Check packages because most processed foods have either soy or corn in them. Better yet, just don't buy processed foods. Eat organic whole foods, especially corn, soy, and russet potatoes (yeah, Monsanto has tampered with these veggies too).
Below are the pictures of the guinea pigs (poor animals) with tumors. Click on the link below the pictures for additional information regarding GMOs and the French study.
Russia bans all GM corn imports; EU may also ban Monsanto GMO in wake of shocking cancer findings
