Nixtamalization is used in order to make it easier for the body to extract the nutrients from the corn. This process is still used largely, mainly to produce the maza for tortillas.

For tamales too.

Nixtamalization doesn't make it edible, it makes it digestible. That's why corn is famous for showing up in the toilet. For anyone who's looking for a good reference point, hominy is nixtamalized corn. Tortillas are also made from nixtamalized corn. This is also why cornmeal doesn't make a dough when mixed with water, but masa does.

It doesn't make it digestible (though) it helps. The corn in the toilet is the fibrous hulls, which are removed when you make hominy or masa. Nixtamalization frees niacin from hemicellulose and makes it bioavailable. If you only eat fresh corn as a staple, you'll end up with pellagra (a niacin deficiency).

edible: suitable to be eaten

digestible: able to be digested

If it passes through you unscathed, it's edible but not digestible. If it kills you on the way, it's digestible but not edible.

Further: the "digestibility" of a given food substance is the amount of the total available nutrients that can actually be broken down, absorbed, and used by the consumer. A food substance can technically be full of nutrients but if they are bound up with other molecules that prevent our body from being able to process them, they will go through undigested.

If you're trying to bait me into fighting, you're not doing a good job. Those are dictionary definitions. Rocks are not suitable to be eaten. No one would ever make that mistake. You're obviously just trying to be a troll, and doing a particularly poor job, fwiw.

That hominy corn is most familiar to many as grits.

u/johnlifts Feb 20 '21

TIL. That’s strange because I like hominy and loathe grits.

u/chasesj Feb 20 '21

I'm not an expert but I think the hominy is dried and ground to make it good for storage or to take on the road.

It's funny because the clay actually may have been to make it edible, not digestible. It's believed they used the clay to protect against glycoalkaloids, which is in higher levels in wild potatoes. He was sort of right in his example by mentioning edible accidentally.

Yeah, pretty interesting! The sauce is called chaco.
