Using NMR/MS based metabonomics and targeted lipidomics approaches the inventors have explored the metabolic phenotypes of aging and longevity in a cohort compromising centenarians, elderly and young adults. The inventors have identified biomarkers for a reduced risk of developing ageing related chronic inflammatory disorders and propose an in vitro method of diagnosing a lifestyle that allows to delay and/or avoid ageing related chronic inflammatory disorders using p-cresol sulphate as biomarker.
