Which are the healthiest countries on this planet? Of course a scientific survey such as this would take into consideration a multitude of factors but in general the longevity is taken into consideration and the reasons for their health looked into what that society provides its citizens, to maintain a lifestyle that helps them lead a healthy life.
Those of us who are acquainted with USA know that it is one of the unhealthiest countries, in fact it comes at number 35, four places behind our little CUBA..

SPAIN
ICELAND
NORWAY
SWITZERLAND 
JAPAN
SINGAPORE
AUSTRALIA
ITALY 
SWEDEN
AND JUST GUESS THE LAST ONE 
ISRAEL 
Being a frequent visitor to Israel I can tell you the reason for their inclusion : excellent food based on Mediterranean Nutritional guidance based on culture and history.
I have either lived or visited repeatedly most of these countries and this list requires an anthropological explanation.

Spain and Italy are not surprises, because of their longstanding cultural nutrition and as well as leisure habits.
I would put Iceland Sweden Norway and Singapore in one category for an innate (and in the case of Singapore, artificial) sense of order of things. Australia and Israel share a genuine desire among its enterprising young people to live a healthy lifestyle which includes good food. We have also to thank the multitudes of Greeks and Italians who migrated to Australia after the war and contributed the mediterranean element .

Thank you Gracias Toda Grazie
