Corn - Research
While there is animal research investigating the effects of purple corn on inflammatory and other diseases,6 there are currently no human clinical studies on the internal or external uses of corn or cornstarch.
Advances in biotechnology are promising for the corn industry where ongoing research is being directed to improve pest resistance.7 Researchers expect to deliver essential nutrients through food enhancement, such as fortifying corn with lycopene. Research has shown an increased bioavailability when lycopene is consumed with corn oil.7
There are several varieties of corn including dent, flint, flour, popcorn, and sweet corn, the vegetable found in grocery stores.2 Corn by-products include corn syrup, bran, flour or starch, germ, flakes, cornmeal, oil, grits, dried corn, masa, parched corn, hominy, polenta, and posole.1
Yellow corn is said to be helpful in building muscle and bone, and corn in general is said to aid in supporting the skeletal and cardiovascular systems.1
