Healthy plant-based diets better for the environment than less healthy plant-based diets — ScienceDaily

Healthier plant-based dietary patterns were associated with better environmental health, while less healthy plant-based dietary patterns, which are higher in foods like refined grains and sugar-sweetened beverages, required more cropland and fertilizer, according to a new study led by researchers at Harvard T.H. Chan School of Health and Brigham and Women’s Hospital.
