"All of our grains are the product of selection, crossing and re-selection; GMO in the slow lane."

I dont' think corn is cross breeding with insecticides in nature.

"In a study released by the International Journal of Biological Sciences, analyzing the effects of genetically modified foods on mammalian health, researchers found that agricultural giant Monsanto's GM corn is linked to organ damage in rats.

According to the study, which was summarized by Rady Ananda at Food Freedom, "Three varieties of Monsanto's GM corn - Mon 863, insecticide-producing Mon 810, and Roundup® herbicide-absorbing NK 603 - were approved for consumption by US, European and several other national food safety authorities."
