People who eat a healthy, sustainable diet may substantially lower their risk of premature death in addition to their environmental impact, according to a new study. This large study directly evaluates the impacts of adherence to recommendations in the landmark 2019 EAT-Lancet report. The researchers have named the dietary pattern outlined in the report — which emphasizes a variety of minimally processed plant foods but allows for modest consumption of meat and dairy foods — the Planetary Health Diet (PHD).
