Recent analyses have highlighted the likely dual health and environmental benefits of reducing the fraction of animal-sourced foods in our diets. Here, we couple for the first time, to our knowledge, a region-specific global health model based on dietary and weight-related risk factors with emissions accounting and economic valuation modules to quantify the linked health and environmental consequences of dietary changes. We find that the impacts of dietary changes toward less meat and more plant-based diets vary greatly among regions. The largest absolute environmental and health benefits result from diet shifts in developing countries whereas Western high-income and middle-income countries gain most in peProceedings of the National Academy of Sciences of the United States of AmericaAnalysis and valuation of the health and climate change cobenefits of dietary change.PMC4839446NE/M021386/1FS/15/34/31656Springmann MGodfray HCRayner MScarborough PfalseAnalysis and valuation of the health and climate change cobenefits of dietary change.What we eat greatly influences our personal health and the environment we all share.
