An Italian study links extreme longevity to inherited DNA from Ice Age Western Hunter-Gatherers, finding centenarians more likely to carry this ancestry and reporting a 38% higher odds of centenarians with that ancestry; paleogenomics shows this pattern, but researchers caution that ancestry alone isn’t a predictor of aging and call for further biological follow-up.
A Swiss study analyzing blood from centenarians (100–105) found 37 of 724 serum proteins resemble those of younger people, suggesting key aging mechanisms can slow rather than stop; centenarians show lower oxidative stress markers, more youthful extracellular-matrix proteins, and a metabolism that remains balanced, with lifestyle factors highlighted as a powerful longevity lever.
Swiss researchers comparing blood from ages 30–60, 80–90, and 100+ found 37 proteins (about 5% of the 700+ measured) in centenarians that resemble the young group more than octogenarians, suggesting key aging mechanisms can be slowed. These proteins affect immunity, metabolism, red blood cell recycling, extracellular matrix maintenance, and oxidative stress, aligning with inflammaging and underscoring lifestyle factors—nutrition, exercise, and social connections—as actionable ways to promote healthy aging.

A Chinese study of more than 5,000 adults aged 80 or older found that non-meat eaters were less likely to reach 100, but this only applied to participants who were underweight. Those who included modest amounts of animal-source foods such as fish, eggs, or dairy had similar odds of becoming centenarians as meat eaters, suggesting that maintaining adequate protein and key nutrients to prevent malnutrition and loss of lean mass is crucial in late life. The study is observational, so it shows associations rather than causation, and it emphasizes that nutrition needs change with age: for the very old, sustaining muscle and preventing frailty may matter more than long-term disease prevention.
A study notes Brazil’s unusually high number of long-lived men and seeks genetic and cellular signatures of aging, while experts emphasize metabolic health, regular exercise, sleep, stress management, and a plant-predominant diet as practical steps to extend healthspan.
Italian researchers analyzed DNA from over 1,000 individuals and found that centenarians carry more Western Hunter-Gatherer DNA, particularly the Villabruna cluster from about 14,000 years ago, which is linked to immune response and cellular repair. In a comparison of 333 centenarians and 690 younger adults, those with hunter-gatherer ancestry had about 38% higher odds of living to 100+, with the signal strongest in women. The study suggests ancient genomic patterns may influence aging and inflammaging, though environment and healthcare remain important and further lab work is needed to confirm functional effects.
An Italian study finds centenarians are more likely to carry Western Hunter-Gatherer DNA, with about 38% higher odds of reaching 100, suggesting ancient ancestry may influence aging, but causation isn’t proven and more research is needed.
Scientists are studying the blood of long-lived individuals like centenarians and supercentenarians to identify biomarkers and factors that contribute to exceptional longevity, with the aim of developing interventions to promote healthier aging for everyone.
A study finds that Italian centenarians have a higher proportion of DNA inherited from ancient Western Hunter-Gatherers, which may contribute to longevity, especially in women, by improving metabolism and stress resistance.
A study of Swedish individuals born between 1920 and 1922 suggests that people who live to 100 or older tend to have a healthy cardiovascular system and maintain a positive outlook on life, which may contribute to their resistance to age-related diseases and exceptional longevity.
Research indicates that people who live to 100 tend to avoid or delay serious diseases, especially cardiovascular conditions, and develop fewer health issues overall, suggesting that resilience and disease management play key roles in exceptional longevity.
A large Swedish study of 44,000 individuals identified biomarkers such as lower levels of glucose, creatinine, and uric acid as associated with reaching 100 years of age, suggesting that metabolic health and nutrition play roles in exceptional longevity, although genetics and chance also contribute.
A comprehensive study reveals that human longevity results from a complex interplay of genetics, epigenetics, metabolism, immune function, and lifestyle choices, with long-lived individuals like centenarians providing insights into healthy aging and potential interventions to extend lifespan and healthspan.
A study of Swedish centenarians reveals that certain blood biomarkers related to metabolism, organ function, and inflammation in midlife can predict exceptional longevity, emphasizing the importance of early health monitoring and lifestyle choices in extending healthspan.
Scientists studying Italian centenarians in Cilento have identified diet, lifestyle, and biological factors, such as a Mediterranean diet rich in olive oil, physical activity, social engagement, and unique immune responses, as key contributors to their exceptional longevity and health. Advanced bio-analytical tools reveal these individuals are biologically younger than their chronological age, with genetic and epigenetic factors playing a significant role, offering insights into promoting healthy aging for others.
