The world of nutrition has long been roiled by fractious debate, legitimate and otherwise, regarding everything from methods of inquiry to public health messaging. The simple reality of our time is that debates about diet for human health are increasingly moot as our options dwindle in tandem with rainforests, glaciers, biodiversity, and aquifers. The impact of our prevailing diets on the planet is fast becoming the only thing that really matters. There will be no point in debating diet for human health on a planet no longer hospitable to human habitation – and we are blithely, and blindly, blundering in that very direction. Obligated to reconcile the exigencies of public and planetary health – as highlighted in the report of the EAT-Lancet Commission on Food, Planet, Health – our pseudoconfusion on the topic of “best diets” for health must yield to a new suite of questions. What are the components making up the environmental footprint of our dietary patterns? What is the best way to measure each? Which matters most? Can they be aggregated? What are the confluences and conflicts between diet for optimal human health, and diet for minimal environmental impact? This talk will explore these issues, and distill them into practical and actionable guidance.
