Are genetically engineered foods safe to eat?  Well ask some environmentalists and they’ll tell you it’s Frankenstein food, but a growing number of health officials say otherwise.  According to the Farm Journal, at a World Food Prize symposium  recently held in Des Moines, Iowa, an FDA official acknowledged that not only are biotech foods safe, but may indeed be safer than foods grown through hybridizaiton, namely because there is less genetic variation when only one or two genes are being modified by an agricultural scientist.   Since biotech is now allowing scientists to grow tomatoes that can act as vaccines against cholera, and new varieties of rice to cure vitamin a deficiency, maybe its time to start labeling biotech crops as “health food.”
