Researchers published a new study in the Proceedings of the National Academy of Sciences that examined for the first time health and climate change benefits of global dietary changes in major regions of the world.
"We project that health and climate change benefits will both be greater the lower the fraction of animal-sourced foods in our diets," the study said.
By adopting a Vegan diet, 8.1 million deaths could be averted per year by 2050, researchers found. Just adopting a diet that is in line with the global dietary guidelines of healthier eating and lower energy intake could save 5.1 million lives. The equivalent for a vegetarian diet translates to 7.3 million lives saved.
The economic benefits of improving diets could translate up to $31 trillion in U.S. dollars or the equivalent of up to 13 percent of global domestic product (GDP) in 2050, the Oxford University researchers said. That's real money, even in Trump's world!
