What was done
A narrative review comparing the Cilento region of Italy with five established Longevity Blue Zones (Okinawa, Nicoya Peninsula, Loma Linda, Icaria, and Ogliastra). The authors searched PubMed/Medline, Scopus, and Google Scholar for literature from 2004 onward in English, German, and Italian, synthesizing 18 selected texts using a descriptive comparative approach across environmental, nutritional, and lifestyle domains.
What was found
Cilento shares multiple descriptive characteristics with established Blue Zones: - Environment: hilly terrain with altitudes between 355 and 600 m, and a mild climate with year-round temperatures between 17.4 and 23.5 °C. - Occupation and lifestyle: traditional employment in agriculture and animal husbandry, active intergenerational family ties, religious devotion, and close community integration. - Nutrition: a predominantly Mediterranean or plant-based diet characterized by legumes, tubers, vegetables, and extra virgin olive oil. No quantitative demographic or longevity metrics (such as centenarian prevalence or validated survival rates) were reported in the abstract.
Why it matters
Synthesizes common lifestyle, dietary, and ecological patterns across recognized longevity hotspots and suggests Cilento as an additional region for investigating determinants of healthy aging.
Limits
The paper is a narrative review limited to 18 non-systematically selected references. It provides descriptive parallels rather than quantitative epidemiological verification of exceptional longevity or validated healthspan outcomes in Cilento.

- supports Epidemiological studies of Blue Zones show that populations with exceptional longevity consume mostly plant-based diets.
