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. The work is yet to be published in a peer reviewed journal, so we need to be skeptical about these numbers for now. But such bold claims are worth further investigation. 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.
