The Mediterranean diet has some of the strongest evidence in nutrition research.
But that does not mean everyone needs to eat a Mediterranean diet to support healthy aging.
Japan provides an important example.
Traditional Japanese eating looks very different from Mediterranean eating. Rice is a staple food. Soy foods, fish, seaweed, mushrooms and green tea are common. Olive oil is not a defining feature.
Yet long-term research has also linked Japanese dietary patterns with lower overall and cardiovascular mortality.
Why can two different diets both be associated with favorable health outcomes?
Because healthy eating is about more than following a particular menu.
Different dietary traditions can provide nutritious foods in different combinations.
This is especially important when thinking about longevity. A healthy diet should not only provide appropriate nutrition. It should also be realistic enough to maintain for many years.
Mediterranean-style eating is one excellent model.
It is not the only possible model.
