Corn
America's number one field crop
The origins of corn remain uncertain. But, it is believed to be a native plant of Central America or Mexico. The United States is one of the major commercial producers of this vegetable. Corn contains vitamins B1, B2 and C, dietary fiber, folate, phosphorus and manganese. These nutrients can help you to maintain a healthy heart and a good set of lungs, as well as a sharp mind. According to The George Mateljan Foundation, dark colored corn products are considered better than the white and yellow varieties, because they contain more antioxidants.
