Acciaroli, a seaside village in Pollica nel Cilento, has been on the international research radar for years due to a striking fact. This area of Cilento is home to an unusually high number of people over ninety and centenarians in good general health. This phenomenon has been studied since 2016 by the project CIAO (Cilento Initiative on Aging Outcomes)This is a collaboration between Italian and American researchers born precisely to understand why people in these countries often age better and longer.
The first answer, the most solid, is that there is no single secretThe same researchers insist on this point: the longevity of Cilento seems to arise from a combination of biological, nutritional, environmental, psychological, and social factors. In other words, in Acciaroli there is no magic formula, but rather a lifestyle that for decades has combined a simple diet, daily exercise, close relationships, and a less stressful pace than the urban one.
The most cited factor is the authentic Mediterranean dietCilento has historically been one of the symbolic areas of this dietary model, already studied by Ancel Keys. The CIAO project materials emphasize that many elderly people in the area still follow a diet consisting of vegetables, legumes, fruit, cereals, olive oil, fish, and little red meat. Among the most curious elements that emerged from the initial research is also the frequent use of rosemary, an herb widely used in local cuisine and rich in antioxidants. Researchers, however, urge caution: rosemary is an interesting clue, not a complete explanation.
Then there is the movement, but not the kind you'd find in the gym. In Acciaroli and surrounding towns, physical activity has been a part of everyday life for years. Walking, gardening, climbing up and down steep streets, working outdoors, and commuting between the sea and the hills. According to the American and Italian researchers involved in the study, this constant and natural activity could play a significant role in the cardiovascular protection observed in many older adults in Cilento.
Another very interesting fact concerns the blood circulationIn one of the first presentations of the results, the researchers noted that older participants showed a surprisingly efficient microcirculation. Comparable, therefore, to that of much younger people. Specifically, lower levels of a biomarker called bio-Adrenomedullin They have been associated with a better-functioning microcirculatory system. It's a technicality, but the meaning is simple: organs and muscles appear to receive blood more efficiently, and this could contribute to healthier aging.
The research then shed light on an often overlooked aspect: the psychological profileStudies conducted in Cilento on nonagenarians and centenarians have revealed common traits such as resilience, optimism, strong family ties, sense of duty, attachment to the land and a certain stubbornness of characterThis isn't folklore: these traits have been described in scientific publications as possible components of a "robust" longevity, capable of navigating grief, hardship, and change without losing inner balance.
Finally, there is the social dimension. The elderly studied in Cilento often live in family and community networks still strongThere's less isolation and more daily contact. And the cognitive results are also surprising. In a study published in 2020, the nonagenarians and centenarians in the sample showed an overall good cognitive state, comparable in some parameters to that of much younger cohabitants.
The point, then, is this: Acciaroli isn't a place where several favorable elements seem to have converged in one place for a long time. And it's precisely this combination, rather than a single miracle, that makes it so interesting to science.
