A third of early deaths could be prevented by this diet change, say Harvard scientists

A third of early deaths could be prevented by this diet change, say Harvard scientists:
"Up to a third of early deaths could be prevented if we all switched to a vegetarian diet, according to new calculations by Harvard Medical School scientists.
While we already know about many of the benefits of not eating meat, this latest figure is much higher than previous estimates.
The researchers presented the figures at the Unite to Cure Fourth International Vatican Conference in Vatican City last week.
...Estimates vary between countries but roughly 30 million deaths every year across the globe are classed as "preventable" – those caused by things we can arguably do something about, such as obesity, smoking, poor diet, and so on.
...What this latest research suggests is that cutting back on meat could be better for us than we ever realised – at least in terms of avoiding an early death.
...Neal Barnard, president of the Physicians Committee for Responsible Medicine, told the conference, as The Telegraph reports..."But when these diets are properly constructed I think they are enormously powerful.""

Quit meat totally and "save" (extend) the lives of .... 1/3 of 30 million whose deaths "could be prevented" divided by 7 billion (world population) = 1.4% possible "lives saved" if we ALL end eating meat for all the world's population..
Right!
