From https://en.wikipedia.org/wiki/Dent_corn https://en.wikipedia.org/wiki/Dent_corn > Dent corn is the variety used in food manufacturing as the base ingredient for cornmeal flour (used in the baking of cornbread), corn chips, tortillas, and taco shells. It is also used to make corn syrup. After a quick search, you need "flint" corn instead of "dent" corn for polenta (it appears to be similar to grits). I guess in case of an emergency anyone is better than nothing. Also, it would be much easier to switch if the people has the know-how. (I'm worried about the availability of enough seeds of the other corn.)
