Planetary Health Diet can reduce risk of early death and help planet, study finds. What is it?

Can a diet that's good for the planet also be good for your health? A new study is pointing to yes. 

In the study, published in The American Journal of Clinical Nutrition Monday, researchers found those who most closely adhered to the Planetary Health Diet had a 30% lower risk of premature death compared to those with the lowest adherence.

Following the diet also had a substantially lower environmental impact, including 29% lower greenhouse gas emissions and 51% lower land use.
