The Sardinian Diet May Be the Secret to Longevity
Sardinia is the second largest island off Italy’s coast. Besides being beautiful, there is a medical mystery about Sardinians that have scientists scratching their heads. Sardinia claims its place as one of the top “blue zones” for longevity, where people live to be well over 100.
At least 220 of Sardinia’s current 1.6 million people have reached 100, twice the average of the rest of the world, and 20 times as many as in the United States. Interestingly, men and women share longevity equally, whereas elsewhere, women reach 100 4 times more often than men.
Sardinia, particularly the central-eastern part of the island, is one of five blue zones that have been discovered by National Geographic Magazine writer Dan Buettner. The other zones of longevity include:
- The islands of Okinawa, Japan – home of some of the longest lived people on earth
- Nicoya Peninsula, Costa Rica
- Ikaria, Greece – the most recently discovered blue spot has the highest percentage of 90-year-olds on earth. Nearly 1 out of 3 people live into their 90s. they also have 20% lower rate of cancer, 50% lower rate of heart disease, and almost no dementia, according to Buettner.
- Loma Linda, California – the only location known in the United States, this area is home to a group of Seventh-day Adventists who live to be centenarians.
Scientists believe Sardinian men share a genetic trait passed from father to son that makes them less likely than the general population to die from heart disease or stroke. But while researchers look for genetic clues, the people of Sardinia attribute this phenomenon to their unpolluted air, lack of stress, and a healthy diet, including wine with very high levels of antioxidants.
