to her cardiovascular health. Even at 117, her blood pressure and other vital markers were comparable to those of a much younger person.
The Role of the Gut Microbiome
Beyond her DNA, researchers were equally fascinated by Maria’s gut microbiome—the community of trillions of bacteria and other microorganisms that live in the digestive tract. The microbiome plays a critical role in digestion, immunity, and overall health, and an imbalance in gut bacteria has been linked to numerous diseases, including obesity, diabetes, and dementia.
Maria’s gut microbiome was remarkably diverse and
resembled that of a much younger individual. It contained high levels of beneficial bacteria, particularly Bifidobacterium, which is associated with healthy aging and reduced inflammation. This unique microbial profile was likely influenced by her diet, which was rich in fiber, fermented foods, and plant-based nutrients.
