What humanity should eat to stay healthy and save the planet (Nature)

Nature published an article on how what we eat needs to be nutritious and sustainable. Researchers are trying to figure out what that looks like around the world. For researchers exploring future diets in some low- or middle-income nations, one hurdle is finding out what people are eating in the first place. “It’s literally like a black box to me right now,” says senior research fellow Purnima Menon, who has been studying diets in India. The data on what people are eating are a decade old, she says.
