Dr. Hammer's 5 Second Takeaways
Food systems sit at the center of almost everything
The report places food at the nexus of food security, human health, environmental sustainability, and social justice - so changing food changes all of them.
This is the full Commission report itself (the library also has a short editorial that introduced it). It's the in-depth scientific case for transforming how the world grows, shares, and eats food so it's healthy for both people and the planet.
The "planetary health diet" is the anchor
A mostly-plant, whole-foods pattern that's healthy for people and sustainable for the planet remains the central recommendation, updated from the 2019 Commission.
Food is the single biggest driver of planetary harm
Even though food systems mostly keep up with population growth, they're the largest single driver of crossing environmental "planetary boundaries."
Healthy food is out of reach for over half the world
More than half the global population struggles to access healthy diets - so fairness (food justice) is a central theme, not an afterthought.
It's a policy roadmap, not a personal meal plan
This is aimed at governments and institutions. For you, the takeaway is the same north star Wholist returns to: real, whole, mostly-plant foods.
Nerd-Out
The 2025 EAT-Lancet Commission (Rockström, Willett, et al.) updates the 2019 report against a backdrop of geopolitical instability, soaring food prices, and COVID-19. It positions food systems at the intersection of the Sustainable Development Goals, the Paris Agreement, and the Kunming-Montreal Global Biodiversity Framework; quantifies food systems as the dominant driver of planetary-boundary transgression; reaffirms and refines the planetary health diet; and foregrounds distributive, representational, and recognitional justice through transformative, sector- and geography-specific roadmaps.
