It is usually believed that the high numbers of centenarians in the Okinawa archipelago result form specific dietary habits.
It is partly true whereas the whole lifestyle may also play a role.
To investigate the issue, we have spent several weeks in Okinanawa.
We then tried to interpret the data at the light of the published scientific literature.
We have recently published in an International Review, the report of our mission in Okinawa.
[Salen P, de Lorgeril M. The okinawan lifestyle: a modern view of an ancestral healthy lifestyle.World review of nutrition and dietetics. 2011;102:114-23].
I recommend to read that article to anyone interested in the role of lifestyle on our health.
