Put the words "genetically engineered" in front of anything -- especially fruits, since they're supposed to be intrinsically healthy -- and it pretty much turns you off eating it in the first place.

In this case, Dr. Mercola points out that, "Most Hawaiian papaya is now genetically engineered to be resistant to ringspot virus," and that studies now show that, "animals fed genetically engineered foods, such as corn and soy, suffer a wide range of maladies, including intestinal damage, multiple-organ damage, massive tumors, birth defects, premature death, and near complete sterility by the third generation of offspring."
