Reconfirmed: Vegetarians Live Longer

Vegetarians live longer than meat-eaters, according to a study published Monday in JAMA Internal Medicine, a Journal of the American Medical Association.

The authors tracked 73,308 members of the Seventh-day Adventist Church for almost six years. The church is known for promoting a vegetarian diet, though not all of its followers adhere to that teaching. Researchers found out what type of diet participants ate, then followed up to find out how many of those participants had died and how.

Vegetarians in the study experienced 12% fewer deaths over the period. Dietary choices appeared to play a big role in protecting the participants from heart disease, from which vegetarians were 19% less likely to die than meat-eaters.

There also appeared to be fewer deaths in the vegetarian group from diabetes and kidney failure.

Caloric intake didn’t seem to matter. The different participant groups generally ate around the same amount of calories daily. Researchers found that the beneficial associations weren’t related to energy intake.

The advantage appeared stronger in men than women, whose diet didn’t seem to make as much of a difference. Eating plant foods didn’t seem to protect participants against cancer, which struck both the vegetarians and non-vegetarians in roughly equal measure.

The paper, written by researchers at Loma Linda University in Loma Linda, California, is larger and includes a more diverse population than previous research, says lead author Michael Orlich, director of the preventive medicine residency program there. “People are confronted with all sorts of nutritional information, but the bottom line is, ‘How will your diet pattern affect your risk of dying?”‘ he says.
