Corn and soybeans have become major crops in the United States. Soybeans are grown for their health benefits, as they are high in nutrients like calcium, omega-3, and fiber, and are linked to reducing heart disease and cancer risks. They are also a major part of the American diet. Corn is also widely used, found in 90% of American foods and used to feed livestock. The United States produces over 300 million tons of corn annually, with over 78 million acres harvested in 2006 alone. These crops have significant impacts on diet, health, and industry in the United States.
