yes,
and the original corn was very different than what we know today.
It only had several kernels per cob and was mostly undigestable cellulose.
Quite honestly corn gets WAY to much credit.
Corn has almost no nutrional value , its mostly cellulose that our bodies cant break down, when consumed as a staple and major part of the diet corn
will "leach" vital nutrients out of of the body.
What doesnt get enough mention is that along with corn the native americans also domesticated beans, peppers, tomatoes, squash, potatoes and
harvested wild rice.
Studies have shown that skeletons of coastal indians from the south east have much better overall health, pre-contact than they do after the european
conquest.
In this particular case the diet of the native americans is pretty well documented, the lived on a varied diet of food they gathered: fish,
shellfish, small game and birds, acorns, wild greens and rice .They grew corn,squash and beans, and they had pretty good health.
But after the europen conquest they were forced to survive on a meager diet of corn and a little dried meat.
The deterioration of the health of native americans is quite drastic, there are signs of a whole host of conditions and diseases that can be traced
to malnutrition.
