Good response and yes, while we don't need to be eating 'Okinawan foods' there is a lot we can learn from the way they approach eating!
I think it's an unfortunate yet predictable development for a city to adopt more fast food and processed foods when it modernizes, and traditional diets tend to drift out not always because of preference but sometimes necessity. While the elderly who live there still adhere to a traditional diet and are enjoying the benefits of it, Okinawa is no longer the healthiest prefecture in Japan because of a younger generation which is more reliant on processed foods.
Not to say we need to eliminate fast food joints and that the older way of living was always better, but we should be encouraging a more balanced approach to eating and ways to manage both the modern diet with traditional ways of healthful eating. To also demand more community-based intervention on the local and prefectural level would help this cause, to help citizens revert back to old ways of incorporating variety and plenty of vegetables into their meals 😊
