Study of world’s oldest person reveals key to ageing well
Scientists who studied the genome, gut health, and lifestyle of the world’s oldest person, who died in 2024 at age 117, have made a breakthrough in their understanding of longevity.
They found that Maria Branyas Morera Morera's cells functioned as if they were about 17 years younger than her actual age, and her gut microbiome resembled that of a child, rich in anti-inflammatory bacteria.
The American-Catalan Caucasian woman’s genome likely contained variations linked to a stronger immune system, reduced cancer risk, and heart disease protection, scientists say.
Ms Morera's lifestyle included avoiding alcohol and smoking, going on daily walks, and enjoying a diet rich in fruits, vegetables, and yoghurt.
The study, which has not yet been peer reviewed, also found that Ms Morera had low levels of VLDL cholesterol and triglycerides, which are linked to heart disease.
