Scientists at King College London (UK) have developed a blood test that could predict how long a person will live, what their long-term health will be and how quickly they will age . The analysis, described in the International Journal of Epidemiology and based on studies with more than 6,000 twins, is based on the detection of a metabolite called C-glyTrp and linked to aging, which functions as a chemical "fingerprint" that is configured in the womb and can be modified by the mother's diet during embryonic development. In fact, this substance is related to the weight of the baby at birth . Certain forms of the molecule are linked to a tendency to undergo accelerated aging and could be identified with a simple blood test that would help prevent the diseases of senescence.
Scientists have identified or tracked 21 substances linked to aging that can be detected in a blood test , which could further refine the prognosis of adult health and the rate of future aging of a person from the moment they are born .
