ERS Explores How Healthier Diets Would Affect Natural Resource Use
USDA’s Economic Research Service (ERS) reported in Amber Waves on how adopting a healthier American diet would change natural resource use in the U.S. food system. A study by ERS looked at how all Americans adopting a diet in keeping with the Federal Dietary Guidelines for Americans would affect use of five natural resources: agricultural land, fresh ground and surface water, fossil fuels, forest products, and air (in terms of greenhouse gases). The study found that adoption of this healthier diet would decrease use of agricultural land, fossil fuels, and forest products by the food system. Meanwhile, greenhouse gas emissions would remain essentially unchanged, but more freshwater would be withdrawn from rivers, lakes, and aquifers.
