A new study published in The American Journal of Clinical Nutrition reveals that following the Planetary Health Diet, which emphasizes plant-based protein and decreases animal-based sources of protein and added sugars, is linked to a lower risk of dying from various diseases such as cancer, cardiovascular, respiratory, and neurodegenerative diseases. The diet also has environmental benefits by reducing greenhouse gas emissions and land use.
According to the study analysis led by Harvard T.H. Chan School of Public Health and the EAT-Lancet Commission, specific foods associated with a lower risk of death include whole grains, nuts, healthy fats like olive oil and sunflower oil, and fruits and vegetables. Reducing red meat consumption is also crucial in reducing the risk of death.
The Planetary Health Diet was developed in 2019 as a more sustainable way to feed the world while considering its impact on human health and the environment. The diet suggests that half of your plate should consist of fruits and vegetables, with the other half being nearly all whole grains or plant protein. Dairy, animal proteins, starchy vegetables, sugars, and processed foods are allowed in smaller portions.
Research shows that transitioning to plant-based diets could reduce diet-related land use by 76% and greenhouse gas emissions by 49%. The top 10% of people who most closely followed the Planetary Health Diet had contributed 29% fewer greenhouse gas emissions, 21% lower fertilizer needs, and 51% lower cropland use compared to those who followed the diet least.
The study's findings emphasize the importance of considering both human health and environmental sustainability when making dietary choices. By following a planet-friendly diet rich in whole plant foods, we can reduce our risk of premature death while also contributing to a more sustainable food system.
