Some people live past 100 with remarkable health, and researchers at Boston University may have identified part of the reason why in the chemistry of their blood.
A study published in GeroScience by researchers at Boston University's Chobanian & Avedisian School of Medicine found that centenarians carry a distinct metabolic profile that is not simply an older version of the typical aging pattern. Specifically, people who reached 100 years of age showed elevated levels of certain primary and secondary bile acids — including chenodeoxycholic acid (CDCA) and lithocholic acid (LCA) — and preserved levels of several steroids, compared to their non-centenarian counterparts.
