Comment: This is why...

people need to look for the Non-GMO Project aproved label: http://www.nongmoproject.org

also you can pick up a Non-GMO shopping guide here:
http://www.responsibletechnology.org/buy-non-gmo

also from this site:
Currently commercialized GM crops in the U.S. include soy (94%), cotton (90%), canola (90%), sugar beets (95%), corn (88%), Hawaiian papaya (more than 50%), zucchini and yellow squash (over 24,000 acres)

So either avoid these foods that are not labeled non-GMO or grow your own.

Even at farmers markets vendors are selling GMO food with the perseption that they are natural. You need to ask the farmer what variety they are growing and verify it's non-GMO
