Is GM food good for you?

“The argument advanced… for the safety of GM food is false… Yes, the DNA of all living organisms is made up of just four nucleosides, and yes, virtually all proteins are made up from just 20 amino acids. But this does not imply that everything containing these basic building blocks is without risk to human beings. The same units, arranged in different ways, are contained in the smallpox virus, bubonic plague and influenza, deadly nightshade and other poisonous plants, creatures such as poisonous jellyfish, scorpions, deadly snakes, sharks – and people who talk absolute nonsense.”
– G. D. W. Smith, Fellow of the Royal Society, professor of materials, Oxford University, UK1

“Most studies with GM foods indicate that they may cause hepatic, pancreatic, renal, and reproductive effects and may alter haematological [blood], biochemical, and immunologic parameters, the significance of which remains to be solved with chronic toxicity studies.”
