Maria Branyas, who passed away in August 2024 at the age of 117, was officially the world’s oldest living person—and she may have held some clues to extreme longevity. According to a new study from the Josep Carreras Leukemia Research Institute in Spain, Branyas’ long life was no accident. Researchers discovered that she had several rare genetic variants, including ones linked to brain health, heart disease resistance, and slower aging. Her cells also had a much younger “biological age” than expected, suggesting they functioned more like those of a younger person.
But her genes weren’t the only factor. Branyas also made lifestyle choices that may have helped her live so long—most notably, her love for yogurt. She ate about three yogurts daily, likely promoting healthy gut bacteria. Researchers highlighted that gut microbes play a significant role in everything from reducing inflammation to supporting brain and bone health.
Her Mediterranean lifestyle also included quality sleep, strong family bonds, mental stimulation through hobbies like reading and gardening, and a nutrient-rich diet. All these factors combined may have contributed to her extraordinary lifespan.
Though she wasn’t the oldest person ever—Jeanne Calment still holds that record at 122—Branyas offers a valuable case study. The takeaway? Longevity seems to be a mix of genetics, lifestyle, and maybe a daily yogurt or two.
What Kind of Yogurt Is Best?
Not all yogurts are created equal. To get the gut-boosting benefits Branyas likely enjoyed, plain, unsweetened yogurt with live active cultures is the best choice. Look for varieties that include probiotics like Lactobacillus and Bifidobacterium, which are known to support digestive and immune health. Greek yogurt is also a good option, as it’s higher in protein and lower in sugar.
Avoid yogurts that are high in added sugars, artificial flavors, or thickening agents. These additives can counteract the benefits of probiotics and contribute to inflammation. Also, steer clear of heavily processed “dessert” yogurts that prioritize taste over nutrition.
