Will it be possible to provide all those people with a nutritious diet in a way that’s environmentally sustainable? The Harvard team created a Planetary Health Diet Index, which quantifies the degree to which a person’s diet adheres to the goals put forth by the commission. The researchers assigned PDHI scores to more than 200,000 people enrolled in the Nurses’ Health Study, the Nurses’ Health Study II and the Health Professionals Follow-up Study. This isn’t the first study to link planetary health diets to a reduced risk of premature death — researchers have seen the connection in the United Kingdom and in Sweden. However, he said more work is needed to show that planetary health diets are as good for the Earth as they are for Earthlings.
