The people inhabiting Blue Zones share common lifestyle characteristics that contribute to their longevity. Among the lifestyle characteristics shared among the Okinawa, Sardinia, and Loma Linda Blue Zones are the following:[4]

Family - Family is put ahead of other concerns.

No Smoking - Centenarians do not typically smoke.

Plant-Based Diet - The majority of food consumed is derived from plants.

Constant Moderate Physical Activity - Moderate physical activity is an inseparable part of life.

Social Engagement - People of all ages are socially active and integrated into their communities.

Legumes - Legumes are commonly consumed. ------
