FYI I did a bunch of research on the Blue Zones (I got sucked into a rabbit hole) and the community-oriented nature of these communities contributes just as much to if not more than the food. So the diets here aren’t necessarily better than reasonable diets anywhere else.

I also remember reading about a tight knit Italian community in Pennsylvania that ate a standard (read: horrible) American diet but were significantly healthier, and once they weren’t as isolated anymore, their health metrics became the same as everyone else.
