Centenarian Blood Reveals a 37-Protein Blueprint for Slower Aging

Swiss researchers comparing blood from ages 30–60, 80–90, and 100+ found 37 proteins (about 5% of the 700+ measured) in centenarians that resemble the young group more than octogenarians, suggesting key aging mechanisms can be slowed. These proteins affect immunity, metabolism, red blood cell recycling, extracellular matrix maintenance, and oxidative stress, aligning with inflammaging and underscoring lifestyle factors—nutrition, exercise, and social connections—as actionable ways to promote healthy aging.
