Planetary Health Diet
The EAT-LancetCommission is a global, interdisciplinary group of world-leading researchers with expertise in nutrition, health, agriculture, sustainability, social justice, and policy – working together towards a healthy, sustainable, and just food system. (1) In 2019 this group’s research developed the Planetary Health Diet being a diet that is both healthier for us and for the planet. It is a dietary outline that can be adapted to suit different cultural traditions and different social contexts – in other words it is a diet that everyone could follow with out difficulty.
“The PHD is rich in plants: whole grains, fruits, vegetables, nuts, and legumes comprise a large proportion of foods consumed, with only moderate or small amounts of fish, dairy, and meat recommended.” (2)
This year their research was updated producing the 2025 EAT-Lancet Commission Report. This report demonstrates that the PHD could both bring the human behaviour back within safe planetary boundaries as well as cutting greenhouse gas emissions.
This 2025 report outlines eight areas where transformation can lead to positive outcomes. Protect and promote traditional healthy diets –
- Create accessible and affordable food environments that increase demand for healthy diets
- Implement sustainable production practices that store carbon, create habitat, and improve water quality and availability
- Halt agricultural conversion of intact ecosystems
- Reduce food loss and waste
- Secure decent working conditions across the food system
- Ensure meaningful voice and representation for food systems workers
- Recognise and protect marginalised groups (3)
