But there is a broad consensus from the best science in the world that GMOs are safe.
Well, I would reword that sentence and say there is "broad consensus from the best science in the world that there is no evidence to support the assertion that GMO's are harmful."

Crazyguy: You stated that "being allergic to gluten is in direct relation to the changes in GMO foods." I will go out on a limb and say that that is absolutely NOT the case. Gluten is a protein found in wheat. Although there have been experiments in genetically modifying wheat in the laboratory, there are no commercially available genetically modified wheat.
So, in conclusion, a gluten allergy in no way can relate to GMOs as there are no commercially available GMO grains that contain gluten.
EDIT: See DJS information above also about gluten allergy being falsely linked to GMOs.
