Hum, Portugal, Japan, South Korea and China (with a really low deathrate for their population), all eat lots of fish... many african countries and australia have both lots of sun and depend on fish also for their diet.

Spain, eat lots of fish also... but maybe food served on hospital and home retirement was not so equilibrated and many of those people were on other medications that could break the intake before.

Is a promising idea
