Commercial yellow dent corn (non-GMO) grown on our farm in Grundy, county Illinois. It's straight from the combine and stored in a bulk storage bin. It's not been cleaned any further. It contains some field debris, cob pieces, small stalks, cracked kernels, etc.

Corn is an excellent source of several important nutrients, including vitamin A, manganese, and potassium. It does contain protein, but it is not a particularly good source. Many other grains contain a greater quantity of protein than corn.
