I am writing today's column from a small, remote, magnificent Greek island. Blue sky, glorious sun, empty beaches. Be happy for me. A generous spirit is one of the marks of a healthy, happy lifestyle.

I am here, on my towel, researching quality of life issues. The Mediterranean style of eating is considered by many experts to be the "healthiest diet in the world." Why take Harvard Medical School's word for it when I can walk to a tiny Greek taverna right on the beach, where the owner cooks a fish he bought from his brother the fisherman, just after sunrise?

The much-revered Mediterranean style of eating is based on real food, locally grown, lovingly prepared by people who quote Homer. Today's field research also consisted of a slice of spinach pie (made next door, by the owner's ancient aunt) and four sensational tomatoes cut into chunks, splashed with olive oil and oregano. The meals are relaxed and emphasize unprocessed foods, healthy fats, fish, vegetables, legumes, a glass of wine. Or two ...

If every child, woman and man in the U.S. followed the basic characteristics of the Mediterranean, we'd solve the heath care crisis overnight. I am serious. Eating this way — more or less, adjusting for ethnic preferences and level of activity — would be hugely helpful for preventing cancer, heart disease, strokes, asthma, allergies, Alzheimer's and more. And there's no suffering involved. The Med-as-in-medicine diet is delicious.

Pretty much.

Not everything.

Have you ever tasted a boiled zucchini?

So what are those basic characteristics of the Mediterranean style of eating? This is exactly the kind of question a person on vacation in Greece likes to hear. For many more details and good recipes, visit www.mediterraneandiet.com

1. High consumption of olive oil. It's sold here by the bucket and is used to cook just about everything. OK, some locals are now using corn oil to make their taramosalata creamier, but just looking around at the tables, olive oil goes on beans, on greens, on cheese, on tomatoes, on fish, on bread, on chins galore.

2. High intake of vegetables, fruits and legumes. "Eat your greens" was one of the first signs excavated at the Acropolis. The Greeks love their veggies, their local fruits, and their peas and beans, and so should you.

3. Use of non-refined carbs. Rice, potatoes and whole grains are celebrated and made delicious. The trick is to adjust your carb portion according to the amount of physical activity you get in a day.

4. Consumption of fish, especially oily or "bluish" ones, three or four times a week. This is getting to be a challenge in the Greek islands, since the Mediterranean seas are overfished and under scrutiny by concerned marine biologists everywhere. Even suspect fish is expensive. At dinner the other night, a Greek friend ordered fried meatballs instead of the only "fresh fish" on the menu because she knew it came from a fish farm. Trouble in Paradise.

5. Consumption of milk and derivatives. Greeks love their simple cheeses — especially goat cheese — and the stores are loaded with variations on the theme of yogurt. You can't force feta into someone's life, but if I could, I would.

6. Three or four eggs a week. The West went wrong went it scared people off eggs. Come back! Eggs from healthy, happy chickens are good for you. On this Greek island, I have a chance to taste eggs from hens I see prancing and scratching around their little houses on my late afternoon runs. It's a thrill, and the eggs can't be beat.

7. Moderate consumption of meat and saturated fat. Moderate is the key word here. Balance in life. The middle way. Avoid excess. The Mediterranean style of eating is part of the laid-back Mediterranean lifestyle that contributes to long life. (I'm saving that research for another day.)

8. One or two glasses of wine a day, preferably red, at main meals. White wine and beer are alternatives.

9. Nuts as snacks. It's almost too good to be true, but it is. Mediterranean-style eaters love their walnuts, their almonds, and so will you, if you decide to look into this Mediterranean Diet thing a little more.

Not me. My work is over for today, and I'm so full I could faint. It might have been that second piece of spinach pie. Opa!
