|Resource title||Still No Free Lunch: Nutrient levels in U.S. food supply eroded by pursuit of high yields|
|Publication/ source||The Organic Center|
|Date published||September 2007|
|Summary text/ abstract||Farmers have doubled or tripled the yield of most major grains, fruits and vegetables over the last half-century. They have done so by capitalizing on the work of plant scientists, crop breeders and companies manufacturing a wide range of inputs – from fertilizer to water, pesticides, sophisticated machinery and diesel fuel. Yield increases per acre have come predominantly from two sources – growing more plants on a given acre, and harvesting more food or animal feed per plant in a given field. But American agriculture's single-minded focus on increasing yields over the last half-century created a blind spot where incremental erosion in the nutritional quality of our food has occurred. This erosion, modest in some crops but significant in others for some nutrients, has gone largely unnoticed by scientists, farmers, government and consumers.|
