The selective pressure on being able to digest lactose as an adult is stronger than the selective pressure to not develop heart disease from eating too much meat, since the former kills you before you can reproduce. Lindeberg claims that humans have sufficiently recent common ancestry that, in absence of the kill-you-before-you-reach-childbearing-age selective pressures, we’re able to generalize from group-to-group fairly well. Non-Inuit probably do worse than Inuit on Inuit diets, and bool is_Inuit is a useful input in a program to produce an optimal soylent blend for someone, but the selective pressure isn’t strong enough for the Inuit to be mostly devoid of heart disease [1] simply because it was selected for.
Also, many other hunter-gatherers from all over eat large amounts of meat (though as much as the Inuit) and are just as devoid of Western disease as are the Kitavans, who consume relatively little, which supports the hypothesis that Inuit aren’t mostly devoid of heart disease because they’re genetically unusual.
[1] IIRC Inuit do suffer from slightly more Western disease than Kitavans (most calories from plants), but not by a very impressive margin.
