I am repeating for the third time, with consistency slightly tinted with lassitude, that I do not have any quantitative studies to support the claim meat is not unhealthy. I was asking for such studies. All I am saying is that countries that do have high meat consumptions per capita, COMPARATIVELY are also countries that have high life expectancy, COMPARATIVELY. I am also stating the factual observation that life expectancy increased in the past 200 years at the same time as people stopped eating dough and potatoes and started to enjoy hamburgers.

These are facts that do not coincide with the stereotype that vegans live longer.

That stereotype actually originated from one study called The Adventist Health Study, a huge study of Seventh Day Adventists who ate little or no meat and showed longevity increases of 7.28 years in men and 4.42 years in women. These data are confounded by the fact that Seventh Day Adventists follow healthy lifestyles free of tobacco and alcohol.

Most other studies either show no difference or are inconclusive. A fascinating paper recently published in the journal Mechanisms of Aging and Development presents an entirely new theory to explain why vegetarians do not live longer. It turns out that those who avoid eating beef suffer a deficiency of a nutrient (carnosine) that is critical to preventing lethal glycation reactions in the body.
