Following the death of Maria Branyas Morera in August 2024 at the remarkable age of 117, a comprehensive study into the supercentenarian’s biology and lifestyle has offered unprecedented insights into extreme longevity. Researchers from the University of Barcelona analyzed the DNA and microbiome of the woman, who was once recognized as one of the world’s oldest people, discovering that her cells exhibited a biological age approximately 17 years younger than her chronological age, coupled with an exceptionally healthy, anti-inflammatory gut flora resembling that of an infant. Beyond genetic advantages, the study points to a steadfast commitment to healthy living, particularly a diet centered around Mediterranean principles and a daily intake of a specific, probiotic-rich food: three servings of natural yogurt.
Decoding the Supercentenarian’s Biological Advantage
Born in San Francisco in 1907 before settling in Catalonia, Spain, Morera’s life spanned two World Wars, the 1918 influenza pandemic, and the COVID-19 crisis, showcasing profound resilience. The genetic and microbiological analysis, led by Dr. Manel Esteller, a genetics professor at the University of Barcelona, represents the most detailed investigation ever conducted on an individual over 110 years old.
The study highlighted significant biological youthfulness. While Morera was 117, her cellular machinery functioned as if she were a century old, a difference of nearly two decades. However, the most compelling discovery lies in her gut health. Researchers found her intestinal microbiome in a remarkable “anti-inflammatory state,” characterized by high levels of beneficial bacteria, particularly Bifidobacteria.
Esteller noted that the supercentenarian maintained “completely clear thought… Her ability to remember fragments from when she was four years old is impressive, and she had no cardiovascular problems, which are very common in the elderly.” This cognitive and physical resilience, he suggested, was anchored partly in her superior internal biological environment.
The Role of the Gut Microbiome in Healthy Aging
The human gut microbiome—trillions of microorganisms residing in the digestive tract—is increasingly recognized as a pivot point for overall health, influencing immunity, metabolism, and chronic inflammation. A balanced, diverse microbiota can mitigate chronic inflammation, a known driver of age-related diseases such as heart disease and dementia.
The prevalence of Bifidobacteria in Morera’s system is critical. This genus of probiotics is known to suppress chronic inflammatory processes and maintain intestinal integrity. The researchers posited that this “baby-like” gut signature provided a crucial physiological foundation for her exceptionally long, healthy life.
Diet and Lifestyle: The Mediterranean Connection
While her genes provided a head start, Morera’s sustained health was intrinsically linked to her disciplined lifestyle and dietary choices, which closely adhered to the Mediterranean diet model.
Daily Dietary Cornerstones: Morera’s most distinguishing food habit was the consumption of three cups of natural yogurt daily. This staple supplied a consistent, potent source of active probiotics, reinforcing her beneficial gut flora, aiding digestion, and potentially reducing risks associated with chronic inflammation, cardiovascular disease, and Type 2 diabetes.
Her overall diet emphasized whole, unprocessed foods:
- Abundant Produce: High intake of fresh fruits and vegetables provided essential fiber and antioxidants.
- Mediterranean Focus: Long-term adherence to the Mediterranean pattern—rich in olive oil, whole grains, and modest consumption of lean proteins—supported systemic anti-inflammatory pathways.
- Avoidance of Toxins: She maintained a strict, lifelong abstinence from smoking and alcohol.
Further aspects of Morera’s routine included daily physical activity, such as walking, and a conscious effort to maintain good social relationships, emphasizing the holistic nature of her longevity strategy.
The findings from Morera’s extended life offer actionable takeaways for individuals seeking to enhance health span. While genetics play a part, prioritizing a nutrient-dense, anti-inflammatory diet—rich in foods like yogurt and fresh produce—along with healthy social engagement and regular movement, appears central to optimizing the biological state for a longer, healthier existence.
