It proves that it is possible. Is a lot in my opinion.

Okinawans aren't vegan people. They eat fish or cephalopods 3 days a week on average, that is less that other Japanese people, but more than a lot of europeans. They eat more pork than average japanese. Its diet includes potatoes, cucumbers, tea, relatively few rice, some meat, all parts of pork, squids, octopus, shellfish, echinoderms, poultry and eggs. As much other lactose intolerant Asian people, they don't use dairy products but this is not for ideological reasons.

In sum, this is not a vegan style life, is an omnivorous low fat content diet combined with a lot of exercise and frequent exposure to cold temperatures.

Many people living in blue zones have several things in common. They are located in coastal areas or next. They exercise moderate but regularly, and avoid stress. Eat small portions and low fat content diets but including both animals and vegetables, and a lot of sea food. They are omnivorous with a wide food spectrum, not vegan.

I never claimed Okinawans were vegan, but they eat less animals, specially fish, than the rest of Japan. That was a counter argument to your correlation between eating fish and longevity.

Again, for the only long term study on a vegan population, look at the US adventists studies, who live longer than any other population in the US.
