Drinking over seven pints of beer a week is the point at which alcohol starts to age your DNA, a study found.
People consuming more than the 17-unit threshold – equal to five large glasses of wine – were found to have ‘older’ DNA.
Data from half a million Britons enrolled in the Biobank was used to look for genetic markers showing how much alcohol a person drinks. People with longer telomeres – repetitive DNA sequences that protect chromosomes – are thought to have longer lifespans.
