Which diets are the most healthy and environmentally sustainable? Many scientists have tried to answer this question by researching the impacts of peoples’ food choices on health and the environment. We compiled all this previous research to summarize how changes to what we eat would affect water use, land use, greenhouse gas emissions, and human health. Overall, we found that if people shifted their diets to eat less animal-sourced food and more fruits and vegetables, it would generally reduce environmental impacts. Furthermore, there would also likely be benefits to health.
