You know those nutrition guidelines the government issues every few years?

It turns out that following them isn't just good for your health.

It's good for the planet, too.

What we found is that impacts vary across nations, but in high-impact nations, in general,

you can see that if you follow a

nationally recommended diet, despite the fact that these diets don't mention explicitly, or most of

them don't explicitly mention environmental impacts, that you are going to have lower environmental

impacts due to that. So that's sort of fairly clear across all the high-income nations.

The food we eat takes a big toll on the environment. A third of the ice-free land on Earth is used for

agriculture, and according to some estimates, producing food accounts for roughly a fifth of all

human-caused greenhouse gas emissions. Fertilizer runoff also leads to other problems, like the

algae blooms in Lake Erie and the dead zone in the Gulf of Mexico. However, following dietary

guidelines would reduce those impacts, especially in wealthy countries like the U.S.

And most of the reductions come from meat and dairy.

Which have an outsized impact on land use and pollution and are a major source of greenhouse gases.
