Ancestral populations like the Inuit, who consumed up to 95% animal products at times, and equatorial populations with high plant food intake, both appeared to do well without developing common modern chronic diseases like diabetes, heart disease, hypertension, and obesity.

“you know you have the Inuit who are at some times of the year at least probably up at that ninety-five percent animal product ratio at other times a year probably lower and there's some evidence that they were pretty active in trading for some you know some plant foods and then you look at like the Catawba and the tuka senta and other more equatorial populations that had a much higher intake of plant foods and they both seem to do pretty well”
