A recent scientific study looked at the impact of different kinds of foods on both human health and the environment's health. To do this study, the scientists used statistics (calculations) to investigate the links between 15 different kinds of foods and five diet-related health conditions and five environmental impacts of producing these foods. For example, the scientists looked at if eating vegetables will prevent us from getting heart disease and how much greenhouse gases come from growing vegetables. They used big data sets from other studies, which they combined using a statistical method called a metanalysis. The scientists found that foods that were good for our health, like vegetables, fruits, whole grains, nuts, and legumes, were also good for the health of our planet. That is, these foods had a low environmental impact on things like greenhouse gas emissions, land use, water use, and two types of nutrient pollution.
