A simple urine test could measure how much our bodies have aged and even how long left we have to live, new research suggests.
Scientists discovered a certain substance, known as 8-oxoGsn, which indicates cell damage, increases in people’s urine as they get older.
By determining people’s ‘internal age’, it may be possible to assess their risk of suffering age-related illnesses and even premature death, according to the researchers.
The efficient urine-analysis technique used by the scientists, which assessed the samples of up to 10 individuals in an hour, may be useful in future studies investigating the link between 8-oxoGsn and biological ageing, they add.Critics argue, however, ageing alone does not accurately indicate the onset of diseases, adding the study did not investigate a link between 8-oxoGsn and conditions associated with the elderly, such as Parkinson’s.
Study author Dr Jian-Ping Cai, from the National Centre of Gerontology in China, said: ‘Urinary 8-oxoGsn may reflect the real condition of our bodies better than our chronological age, and may help us to predict the risk of age-related diseases.’
