#2 yellow dent corn is an essential food?

Aside from ethanol, is it used for anything else than the food supply chain?

Corn meal is made from #2 as is High Fructose Corn Syrup. HFCS has undesirable qualities but there is no doubt it is used in many foods and drinks in the US.

Mmmm. More high fructose corn syrup for me.

As an aside, less than 5% of the US corn harvest is consumed by this product (which is hardly an "essential" food).
