What exceptional characteristics do people have who live a long time, maintaining their quality of life even at an advanced age? Researchers have discovered some very interesting things about Brazilians.
In our modern world, longevity is an intensely discussed topic, especially from the point of view of biohacking strategies: cold baths, expensive wellness clinics that analyze your hormones in detail, superfoods, intermittent fasting, etc. We think more and more how to cheat aging, how to live up to 150 years with a body that functions almost as well as in youth.
And yet, something very different is happening in Brazil, say the health specialists from Mindbodygreen.
Without access to luxury longevity clinics or experimental anti-aging therapies, many Brazilians routinely live to be 100, 105 or even over 110 years old. In fact, Brazil is home to three of the ten longest-living men in recorded history, including the world’s oldest living man, born in 1912. Even more remarkable is the fact that many of these men remained independent, clear-minded and relatively healthy into extremely advanced ages.
A new scientific point of view, published by researchers who study Brazilian centenarians and supercentenarians, analyzes more carefully the reasons why these people have such a long and healthy life. And while there is no single “secret,” their findings challenge some of our most common assumptions about aging and the true source of longevity.
The remarkable advantage of longevity in Brazil

Researchers have long studied centenarians because they represent something rare: people who have managed to avoid or delay many of the major diseases associated with aging, including cardiovascular disease, cancer and dementia.
From this point of view, Brazil offers a special opportunity. It is a country with one of the most genetically diverse populations in the world, shaped by centuries of indigenous heritage, African influences, European immigration and a significant Japanese population. This rich genetic diversity creates biological patterns that do not appear in more genetically homogeneous populations, and many of these patterns are still missing from global genomic databases.
It is also important that many Brazilian centenarians grew up and lived in regions with limited access to modern medical care. This allows researchers to study longevity that is not heavily influenced by advanced medicine, making it easier to identify biological and lifestyle factors that can support long-term health.
What the researchers discovered
Scientists are studying over 100 Brazilian centenarians, including 20 supercentenarians, to understand what keeps them in shape. The research reveals three key biological advantages that differentiate them from ordinary patterns of aging.
One of the most striking discoveries involves the maintenance of proteins, sometimes called “cellular cleanliness”. As we age, the body becomes less efficient in eliminating damaged or incorrectly folded proteins. This degradation contributes to inflammation, neurodegeneration and loss of function.
Supercentenarians seem to defy this decline. Their cells maintain protein quality control systems—such as autophagy and proteasome activity—at levels similar to those of much younger adults. In short, their cells remain better organized and less “crowded” over time.
The immune system tells a similar story
Instead of a steady decline, the immune systems of supercentenarians seem to adapt. They show signs of resilience, not exhaustion, with immune cells that remain effective in fighting infections and managing inflammation. Some even show unusual immune profiles for advanced age.
Genetics also play a role. Long-lived individuals often carry rare genetic variants associated with immune regulation, DNA repair, mitochondrial health and genomic stability. These are not “longevity genes” in the simplistic sense, but rather combinations that support resilience when the body is under stress.
What does this mean for the rest of us?
Most of us were not born in Brazil and we cannot choose our genetics. But this research reinforces something that longevity science constantly returns to: the length of a healthy life matters more than the total length of life.
Experts draw attention to several recurring themes that appear in long-lived populations:
Metabolic health is a priority
Maintaining muscle mass, blood sugar balance and low inflammation support almost all systems involved in aging.
Movement matters more than intensity
Many supercentenarians have remained physically active through daily activities. Constant walking, maintaining strength and mobility seem more important than extreme training.
Muscles are protective
Bone strength and density are closely related to survival during diseases and injuries in old age.
Small habits count over time
Regular sleep, reduced stress, eating whole foods and social connections play important roles over decades, not weeks.
What is happening in Brazil is a reminder that longevity is not built only in luxury laboratories or clinics. In many cases, it is shaped slowly, through a resilient biology, daily movement and strong muscles.
Scientists hope that ongoing genomic and cellular research will uncover new targets for extending healthy life spans. But what we learn from here is that aging well does not require perfection. It requires habits that support the body’s ability to repair itself, adapt and remain functional over time.
