I agree with Nancy LC - that the issue is that much of the GMO involves toxins being combined into products like corn:
"Upwards of 85 percent of U.S. corn crops contain a special gene added that allows them to produce an insecticide. This way, when bugs attempt to eat the corn they're killed right away (specifically their stomach is split open) because the plant contains an invisible, built-in pesticide shield.
The particular gene added to most corn crops is a type of Bt-toxin -- produced from Bacillus thuringiensis bacteria. Genetic engineers remove the gene that produces the Bt in bacteria and insert it into the DNA of corn (and cotton) plants.
They claim that Bt-toxin is quickly destroyed in human stomachs -- and even if it survived, it won't cause reactions in humans or mammals ...
But studies are now showing that this is not the case, as Bt toxin is readily passing into the human bloodstream and animal studies have already shown that Bt-toxin does cause health effects in animals, including potentially humans."

The article goes on to say that these health effects include cancer, arthritis, Lou Gehrig's disease, atherosclerosis, osteoporosis and allergies.
So, if you are eating any corn that is not organic - you are ingesting these toxins. That includes high fructose corn syrup - which is in a high majority of our foods.
And we feed this stuff to our kids? These diseases will cost us a lot more than what we will ever save in "cheap food".
