What is interesting about Seventh-day Adventists, aside from being a slightly different protestant denomination, is that they preach a very strong health message -- it's not like don't do these things and you'll go to hell, they don't actually believe in a literal hell anyway, it's closer to "The body is the Temple of God so you should take care of it".
Anyway, I digress. Adventists are by and large vegan or vegetarian (even after leaving the church I grew up in I'm still vegetarian), they don't drink and they don't smoke. They live on average a decade longer.
There are many factors that can lead to longer life and longer quality of life, as evidenced by other bluezones, but these are relatively easy changes that you can make to your life that will have a positive impact.
Hell you don't even have to be fully vegan/vegetarian to get the benefits. Just swap out a bunch of meals that would otherwise have meat with vegetarian alternatives. Have a steak once a month vs once a week (etc).
Note: My father is a retired Adventist pastor in Australia. I am no longer religious but was within the Adventist church from 0 to 22ish.
