Secret of long life in Italy village revealed
Print Edition
SCIENTISTS yesterday revealed part of the secret to why a small village in southern Italy has an unusual number of centenarians — low levels of a particular hormone that affects circulation.
Italian and US experts have spent the last six months investigating the extraordinary longevity of residents of Acciaroli, where more than one in 10 — 81 at the mayor’s last count — of the village’s population of 700 is over 100 years old.
Acciaroli is part of the Cilento coast, an area of outstanding natural beauty where the late US nutritionist Ancel Keys first established convincing evidence of the health benefits of a Mediterranean diet based on olive oil and rich in fresh fruit, vegetables and fish.
As well as reaching extremely old age, people in Acciaroli and tiny communities nearby also seem to be largely immune to dementia, heart disease and other chronic conditions associated with ageing in most of the Western world.
Researchers from Rome’s Sapienza University and the San Diego School of Medicine said yesterday that the explanation could lie in low levels of adrenomedullin, a hormone that acts to widen blood vessels.
Adrenomedullin is present “in a much reduced quantity in the subjects studied and seems to act as a powerful protecting factor, helping the optimal development of microcirculation,” or capillary circulation, they said in a statement.
Capillary blood vessels tend to degenerate in older people, but the seniors in Cilento had capillaries of the sort found in much younger people, even those in their 20s.
The study also found “metabolites present (in the bodies of those studied) which may have a positive influence on longevity and the well-being of Cliento’s centenarians,” the statement said, without giving further details.
The researchers have decided to extend the study and expand their research, including by launching a fundraising campaign.
The scientists are looking into whether genetics could combine with lifestyle factors — diet and physical activity — to extend the villagers’ longevity.
