"The central question about vegetarian diets used to be whether it was healthy to eliminate meat and other animal foods … Now, however, the main question has become whether it is healthier to be a vegetarian than to be a meat eater. … The answer to both questions, based on currently available evidence, seems to be yes. A properly planned vegetarian diet can provide all the essential nutrients, even for growing children … And, on the whole, vegetarians are less likely to be afflicted with the chronic diseases that are leading killers and cripplers in societies where meat is the centerpiece of the diet."
