Hey,
Corn is among the few crops which including rice and wheat which consumed all over this blue planet. You have explained it clearly why should we eat maize more instead of other kind of crops.
Maize is one of the fewest crops which are being consumed by the humans from ancient times. It is easier to grow and cultivate and can be grown in almost every kind of environment. When it comes to it's nutritional values, it is overloaded with vitamins, good cholesterol, protein, antioxidants and tons of other healthy elements.
Thanks
