The January issue of the American Journal of Clinical Nutrition posted an article claiming that vegetarians had 32% less heart disease than those eating meat and fish. The type of meat eaten was not disclosed. There are major differences between feed lot beef and grass fed beef or wild game that went unaddressed.
Of course it is misleading and generalizing to put all meats into the same category when there are major differences in each of them. So, the conclusion that vegetarians have a lower risk for heart disease may well be true for feed lot beef, but we need another study to evaluate both grass fed beef and wild game.
