Sweet corn belongs to the same species as field corn (Zea mays) but has a genetic mutation (or mutations) that results in the corn kernels storing relatively more sugar than commonly grown field corn. Varieties with this mutation were first discovered and grown in Pennsylvania in the mid-1700s.Sweet corn is a good natural source of iron which might help form blood cells. Thus, it may help manage anaemia. It also contains folic acid and niacin, which are important for forming blood cells. In addition, folic acid and vitamin B12 may prevent the development of anaemia resulting from vitamin deficiency.
