Does science back the blue zone diet?Further reading
The concept of blue zones originated when a large proportion of male centenarians were identified in Sardinia by Michael Poulain and Gianni Pes, who published their findings in the Journal of Experimental Gerontology. Olive oil, which has been found to lower bad cholesterol and increase the level of good cholesterol in the body, is commonly used. Oleocanthal, a vital component of olive oil, has proven anti-inflammatory properties. According to a report in Ikaria , a daily consumption of six tablespoons of olive oil can reduce the risk of death by 50% in middle-aged people.
Eggs form an important part of the blue zone diet and are consumed by Okinawans , Nicoyans , and Mediterranean people as well. These are eggs hatched from healthy chickens that grow naturally and mature without any intake of hormones or antibiotics. They are thus rich in omega-3 fatty acids. Liquid intake, especially red wine, is also a major dietary habit followed by individuals residing in the blue zone areas. Sardinians moderately consume Cannonau wine, which contains twice the amount of artery-scrubbing flavonoids than other wines.
