Changing the way the world eats could reduce premature deaths, save trillions of dollars and slow the impact of climate change, according to a report from the 2025 EAT-Lancet Commission.
70 leading experts from 35 countries came to the conclusion that the adoption of the “Planetary Health Diet” (PHD) could prevent 15 million premature deaths a year and halve the global emissions of the food system.
The diet is more so a set of clear guidelines that benefit both our health and the planet. However, across all dietary preferences and requirements, the recommendations are the same. Eat more vegetables, fruits, nuts, legumes and whole grains.
These guidelines are made to be flexible as Walter C. Willet, the co-chair of the commission and a professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health, says, “[The diet] allows for cultural diversity and individual preferences, providing flexibility within clear guidelines to achieve optimal health and sustainability outcomes worldwide.”
Our current food system contributes one third of global greenhouse gas emissions as well as contributing immensely to deforestation, biodiversity loss and water pollution. By adopting the PHD, researchers believe we could cut our food emissions by half.
The report also points to severe inequalities in the food system. It found that the wealthiest 30% of the world’s population generates more than 70% of food-related environmental damage. Plus, 2.8 billion people cannot afford a healthy diet and 1 billion are undernourished, despite the world producing enough food to feed everyone.
The shift in diets is necessary, according to the report, but calls for other changes to the food system, including cutting food waste (according to the UN the world wastes one third of its food), eco-friendly farming practices, and decent working conditions, as a third of food workers earn below living wages.
“Investing in and scaling up efforts to reshape global food systems now is the best way to build toward a sustainable, equitable future," said Line Gordon, a commissioner and the director of the Stockholm Resilience Centre at Stockholm University.
