Yes, I know what all the GMO corn and soy are in...which is why I avoid processed food as much as possible.
This use of pervasive use of corn and soy products is why the GMO industry doesn't want it labeled....
If you read up, you find that the GMO plants are increasing the amount of Round-up needed because of new "super-weeds". Farmers are less likely to rotate crops, so soils are becoming depleted, and other pests are lingering. Monsanto's GMO corn is producing resistant root borers with the Bt corn.
Round-Up should be used when the plant is young, it has a less developed immune system and is likely to be killed by the chemical. Instead of spraying twice, once to catch the early weeds, then to catch the weeds that grow after that, some farmers have started spraying only once when the weeds are a bit older. When the plant is more mature, it has a greater chance of surviving the chemical and developing a resistance to it.
I don't mean to say that Monsanto is always right in what their doing, but they do catch a lot of flack for things that aren't entirely their fault.

There are also health concerns with GMO foods. At minimum, they should be labelled, so that people can make a choice.
Theres way too much to label though. Pretty much everything in an American supermarket that isn't organic contains GMO products, be it corn, soybeans, canola... That sorta thing.
