Hard to tell what the kitavans ate after they immigrated that ruined their health, but I'd be willing to bet it was the grains that was most responsible.
The kitavan diet was high in % of saturated fat, if I recall correctly, not necessarily super high in total fat though. So if they ate 30% of their calories in fat, that's not high. But if 85% of that 30% was saturated fat (coconut fats) then if you don't read carefully, it sounds like it is a super high fat diet.
In fact, from the blog you probably got your info, they ate a rather low fat diet:
Quote:
Grains, refined sugar, vegetable oils and other processed foods are virtually nonexistent on Kitava. They get an estimated 69% of their calories from carbohydrate, 21% from fat, 17% from saturated fat and 10% from protein. Most of their fat intake is saturated because it comes from coconuts. They have an omega-6 : omega-3 ratio of approximately 1:2. Average caloric intake is 2,200 calories per day (9,200 kJ). By Western standards, their diet is high in carbohydrate, high in saturated fat, low in total fat, a bit low in protein and high in calories.

So I think that means they had about 38% of calories from fat total. Which isn't all that high fat by our standards.
I can think of a number of ways they could've been healthy from that diet, none are provable yet:
Coconut fat is really good for you.
Fish is really good for you.
Maybe the carbs in tubers and the sort of fruit they ate are not bad.
or some combination of those things.
And they ate that way from childhood, coming from healthy mothers who also ate that way.
It might be a totally great diet, but only if you're healthy to begin with.
