13 Jun 2024 --- A recent study conducted by researchers from Harvard TH School of Public Health, US, found that people with a higher adherence to the Planetary Health Diet (PHD) — also known as the planetary or planetarian diet — had a 30% lower risk of premature death compared to those with the lowest adherence. PHD is a flexitarian diet created by the EAT-Lancet Commission in 2019. The current study developed a PHD Index (PHDI) to quantify adherence to the EAT-Lancet reference diet.
