The risks that GMOs pose to us are more likely to come from the companies that grow them. The corn they grow here in the states is used for everything from plastics to soda and new uses are undoubtedly being uncovered all the time. Personally, I don't like corn THAT much. A corn takeover is not much of a doomsday scenario.
There are some environmental issues that arise from supporting corn crops. Some crops 'give back' to the soil. Corn is not one of them.

Another, keener health risk concerns something I heard about The Omnivore's Dilemma. The problem with some GM foods I hear is that they are far lower in nutritional value than other foods.

It's been a while since I looked this up, but if memory serves several GM crops have been modified to produce extra nutrients. Except for knock-on effects of modification for e.g pesticide resistance I don't see any reason why someone would engineer nutrients out of a crop. And of course, if you eat a balanced diet with a variety of foods you'll probably be fine nutrition-wise.
I was raised to believe that genetically-modified foods are unhealthy to eat and bad for the environment, and given a variety of reasons for this, some of which I now recognize as blatantly false (e.g., human genetic code is isomorphic to fundamental physical law), and a few of which still seem sort of plausible.
Because of this history, I need to anchor my credence heavily downward from my sense of plausibility.
The major reasons I see to believe that GMOs are safe are:
