Truthfully, I’ve not heard of the education tribe before or since. But it is the Pima Indians that have horrific problems with diabetes.
The Pima are an odd bunch. Often black in skin tone, but a purplish black, not a brownish black like Negroes. The theory is that after centuries of living in near starvation conditions, their livers became extremely efficient, to the point where a hard working adult Pima could comfortably survive on 600-800 calories a day. (Hard working White Americans need over 2000 for adult women and 2800 for adult men.)
But there’s more. One of the main staples of the Pima diet was flour from ground mesquite bean pods. It is very low on the glycemic index, so diabetes was unheard of in the Indians of the time.
Yet you feed a Pima Indian a white style diet and they will balloon up.
It was a very tough life back then. Some of my Ute relatives used to war with the Navajo way back when. Both were damn proud of the fact that the Spanish never succeeded in enslaving them.
They had that in common with the Pima and Pueblo, though some in the Pueblo group did eventually surrender to the Spanish and come into the Missions. These ancient wars come with deep regret even to this modern day because we really didn't hate each other. We were just trying to survive the Spanish, Comanche and other more aggressive groups that wouldn't just leave us alone.
Some say we always lived in what is now the American Southwest. Some say we may have moved there to escape the deprivations of the Aztec further south. Probably some of both. My Navajo friend claims dependency from the Anasazi which, as you probably know, predate the Aztec by at least a millennium.
Sorry.
Lamanites!
