You bring up an excellent point about the glycemic index. I recently read that testing on carrots revealed that they actually do not raise the glycemic index all that much.

With respect to Mexican corn - Native Americans, be they born in Alaska, Canada, USA, Mexico, Central America, whatever - they stay skinny if they eat a native diet, but balloon up and get Type 2 diabetes if they eat a European diet.

My guess is that someday researchers will realize that what you can eat has a lot to do with where your ancestors came from.

White corn tastes yummy because it is genetically engineered to taste sweet. Native American ancestors are adapted to yellow corn, not sugar corn.

I'm pretty sure that the white corn that So Cal tortilla shops buy is a large kernel feed corn, not the kind you eat off the cob with butter and salt. The torties made from it aren't sweet at all, just soft and delicious.

Not all "Native Americans" were corn-eaters.
The Plains Indians ate MEAT - i.e.: Buffalo - and lots of it!
