Khaberni - María Branias Moreira lived an exceptional life lasting 117 years before her death in 2024, but her medical legacy is still alive. A recent scientific study showed that the secret behind her longevity might lie in the diversity of her gut microbiome, which resembles that of much younger people.
A youthful microbiome in an aged body
Through analyzing the gut bacteria of Branias, scientists discovered that her microbiome's diversity unusually remained high with age, a factor believed to contribute to longevity and quality of life.
Researchers point out that her lifestyle and dietary regimen, based on daily yogurt and a Mediterranean diet rich in fruits, vegetables, whole grains, and olive oil, played a pivotal role in supporting this diversity.
Bacteria "Bifidobacteria".. a mark of health
Analyses showed an abundance of bifidobacteria known to boost the immune system, protect the digestive system, and regulate cholesterol. This unusual diversity likely helped strengthen her immunity and maintain her health over decades of her life.
Dietary habits supporting longevity
Branias consumed three types of yogurt daily, nourishing the beneficial bacteria in the gut. The Mediterranean diet she followed is known for its ability to enhance the health of the digestive system and reduce the risk of chronic diseases. Foods that also support a healthy microbiome include kefir and fermented vegetables such as kimchi and sauerkraut, plus prebiotic-rich foods like onions, garlic, bananas, and legumes.
Genetic interactions with lifestyle
Although Branias carried protective genetic variants that helped her avoid common diseases, the study confirms that genetic factors are not alone decisive. Daily choices, especially dietary ones, significantly impact the health of the microbiome, and thus the quality and length of life.
Lessons from the world's oldest survivor
The case of María Branias Moreira reveals the deep connection between nutrition, gut health, and longevity. While a healthy diet does not guarantee a life extending over a century, it reduces the risks of serious diseases like heart disease, cancer, and diabetes.
Simply put, we can't change our genes, but we can support our bodies from the inside by taking care of our gut microbiome, which may give us a better chance for a longer and healthier life.
