The Secret of Italian Longevity: Scientists Reveal Where the Most Centenarians Live in Italy

Italy continues to rank among the world’s most “ageing” countries, with the number of people reaching 85, 90, and even 100 years of age steadily increasing. A new study published in the journal Nutrients has shown that life expectancy varies significantly across different regions of the country.

Researchers found that the highest levels of longevity are more often observed in central and northern Italy. The regions of Liguria, Tuscany, Emilia-Romagna, and Trentino-Alto Adige stand out, with some of the highest proportions of people living beyond the age of 90.

At the same time, several southern areas also demonstrate remarkable longevity patterns. For example, the Cilento region showed survival rates into advanced age comparable to those seen in famous “longevity zones” such as Sardinia.

The researchers noted that over recent decades, Italy has experienced a decline in mortality from many chronic diseases, including heart disease, stroke, and diabetes. However, significant regional differences remain: northern areas tend to have healthier dietary patterns, higher vegetable consumption, and more regular breakfast habits, while southern regions show higher rates of overweight and obesity.

The connection between diet and longevity was particularly noteworthy. Regions with higher vegetable consumption generally had more people reaching their 90s and 100s, while higher obesity rates were associated with less favorable longevity outcomes.

The study also confirmed a well-known trend: women have a significant advantage in life expectancy, and their numbers among the oldest age groups are considerably higher than those of men.

The authors emphasize that the study identifies broad regional patterns and does not prove that any single food or lifestyle habit can guarantee a longer life. However, the findings reinforce the importance of a healthy diet, weight management, and prevention of chronic diseases in promoting healthy ageing.

The Italian experience shows that longevity depends not only on genetics but also on lifestyle, the environment, and food culture.
