Here’s an excellent article on the phenomenon of longevity on the Greek Island of Ikaria: “The Island Where People Forget to Die”.
In a study of 673 Ikarians, it was found that:
“… subjects consumed about six times as many beans a day as Americans, ate fish twice a week and meat five times a month, drank on average two to three cups of coffee a day and took in about a quarter as much refined sugar — the elderly did not like soda. [It was] also discovered they were consuming high levels of olive oil along with two to four glasses of wine a day.”
Note that most everything the Ikarians consume is home grown, including the wine and the livestock. Which supports my recent contention that being healthy doesn’t necessitate a raw diet, nor does it require one to be vegetarian. What it requires is for food to be the way nature intended, not the way man engineered.

Of course, lifestyle and the lack of stress are also key. The Ikarians live so well that they forget to die. We should learn from their wisdom.
