Centenarian-Style Eggplant Flatbread


This year, the Fun Food Feed is featuring longevity blue zone regions (BZ) from around the world, and dishes inspired by them.

Spring’s featured longevity blue zone region is Sardinia, Italy.


A blue zone region is a “small, homogenous geographical area where the population shares the same lifestyle and environment and its exceptional longevity has been scientifically proven.”

National Geographic researchers originally identified five blue zone regions: first Sardinia Italy, next Okinawa Japan, and the Seventh Day Adventists of Loma Linda California, then the Nicoya Peninsula of Coast Rica, and Icaria, Greece.

Nine shared lifestyle habits were found in all five populations:

  1. Plant-Based Diet with legumes as a staple
  2. Moderate Calorie Intake, stopping eating when feel 80% full
  3. Moderate Alcohol of 1-2 glasses per evening (except Adventists, who abstain)
  4. Moving Naturally, growing gardens, walking to the store, house and yard work by hand
  5. Life Purpose
  6. Stress Reduction, with meditation, prayer, naps and socializing
  7. Belonging to a positive community, often faith-based
  8. Family, with members committed to helping each other
  9. Social Circle of several supportive members with healthy behaviors

These populations with a high proportion of centenarians have not lasted indefinitely, depending on the above factors being maintained.



A common greeting on the island of Sardinia, Italy is a kent’ annos, meaning “may you live to be 100.”

Sardinian blue zone region centenarians occupy the rocky highland slopes of the Supramonte mountains.  The longest living here are the men, who spend most days shepherding their flocks of slender sheep and goats over rugged hills of wild grasses and herbs.


One might guess that these pastoral roots would make the cornerstone of their diet meat, but meat is reserved only for holidays.

Daily fare for a traditional Sardinian centenarian family is durum wheat and barley bread and sourdough, fava and garbanzo beans, and whatever is ripe in the garden, including eggplant, zucchini, tomatoes, cabbage, fennel, onions and potatoes.  Their grass-fed pecorino and chopped almonds are common condiments.

These plant-based foods are rich in vitamins, minerals, carbohydrate, protein, phytonutrients and prebiotic fiber.

This Spring’s Featured Recipe is for Centenarian-Style Eggplant Flatbread.  What better way to bring Sardinia’s traditional foods together into one dish!  And what better way to bring friends and family together than with good food.




If time is of the essence, substitute pre-made refrigerated whole grain pizza dough, slices of sourdough bread or english muffins, or your favorite flatbread for our overnight flatbread dough below.

Vegetables can be finely diced and mixed with tomato sauce before topping pizza, for a more “classic” look and for the more reluctant vegetable eater.
