The Claim
Geographic isolation and historical starvation events may have intensified natural selection for insulin resistance in certain human populations, such as the Pima Indians and Nauruans, leading to a higher genetic predisposition to type 2 diabetes when these populations adopt modern high-carbohydrate diets.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Some groups, like the Pima Indians and Nauruans, might have genes that store energy more efficiently because of past famines and being cut off from others — which helped them survive back then, but now makes them more likely to get type 2 diabetes when eating modern diets full of carbs.

Geographic isolation and historical starvation events may have intensified selection for insulin resistance in certain populations, such as the Pima Indians and Nauruans, contributing to their high genetic predisposition to type 2 diabetes when exposed to modern high-carbohydrate diets.
What the research says
1 studyStudy: The carnivore connection: dietary carbohydrate in the evolution of NIDDM
The study says people who ate very little sugar and carbs for many generations evolved to become insulin resistant to survive, which now makes them more likely to get diabetes when eating modern diets. This supports the idea that some groups are more at risk because of their ancestors' diets.
