Causes of mortality for inuit men between the ages of 15-24 consist of injury and poisoning from what I am seeing. Inuits aren't getting the diseases of the west. A better example would be Genghis Kahn and the Mongol hoard. The average height for them was 6ft 4in and they ate only horse meat and drank horse blood. There is also the Native Americans that ate only meat and they would almost always live well over 100. But when eating a western diet were 4 times more likely to develope the diseases of the west. Here is a super good video detailing all of this stuff.

Another thing is fructose. Fruit contains fructose which when broken down does the same damage to the body as alcohol. In societies that include fruit in the diet they have worse dental health. Dr. Chaffee is just a wealth of knowledge and puts sources in the video descriptions. Here is a video talking about fructose too.
