There are no foods that contain corn, soy, canola, papayas, or any foods that are known to have been genetically modified that can be guaranteed NOT to contain any GMOs, not even foods labeled "100% organic" or foods on the Non-GMO Project's list of non-GMO foods. This is due to GMO varieties cross-pollinating with organically grown crops, which has resulted in the possibility, if not probability of organically grown foods having small amounts of GMOs in them. The foods on the Non-GMO Project list can actually contain up to 0.9% GMOs (as stated on the Non-GMO Project's website).

GMO foods asummably have the same vitamins as the equivalent non-GMO foods.

If you are a farmer, you know the corn you are gowing is GMO because you buy seeds that are known to be GMO. If you are gowing non-GMO varieties, you do not know if GMO vaieties have cross pollinated with your corn unless you get it tested.

If you are a consumer, you do not know if the corn or processed foods containing corn is GMO unless it is labeled as such. In the United States GMO foods are not labeled.

GMO stands for genetically modified organism. To confirm the GMO status of the sample, it must be labeled as GMO by the producers.

GMO corn and soy are no more productive than non-GMO corn and soy.
