"If you're looking for the definitive study that might persuade meat lovers to become vegetarians, this may not be it."

"New research published in JAMA Internal Medicine finds that vegetarian diets are linked to a slightly lower risk of early death — about 12 percent lower over a period of about six years of follow-up. But the link to longevity was more significant in men compared with women."

"The study is based on a one-time survey of more than 70,000 Seventh-day Adventists, a religion that emphasizes healthful diets and abstaining from alcohol, caffeine and tobacco as part of a godly lifestyle. Not all adherents are vegetarians, but the church considers a meatless diet to be the ideal."
