The US is the biggest producer of corn. To an almost excessive level. Our government actually subsidizes corn farmers to grow more than we need so we have a surplus of corn to trade. Corn actually can be made into a whole bunch of other things including many artificial flavorings and additives to food. High fructose corn syrup is a byproduct of corn and is generally cheaper than sugar to put in food. That's why it's everywhere. So to answer your question the U.S grows the most by far.
