Sean Murphy’s claim that l in 5 vegans are nutritionally deficient is insane and he offers no evidence to back up his claim. For the “millionth” time a recent study in the Journal of the American Medical Association showed vegetarians live longer than meat eaters. He gives no evidence (as usual!) that vegans are vitamin B12 deficient (many vegans take vitamin B12 supplements to be on the safe side). If people stopped eating meat, farm animals would soon become extinct and then the environment would greatly improve.
