Drinking coffee may do more than provide a morning boost, it could also help protect the liver, according to one of the largest studies on the subject.

Researchers at Cedars-Sinai Health Sciences University analysed data from nearly 355,000 adults in the UK Biobank over a median of 13 years. They found that people who drank coffee were less likely to develop cirrhosis, liver cancer or die from liver disease than those who did not drink coffee.

Participants who consumed five or more cups a day had a 32% lower risk of cirrhosis, a 47% lower risk of liver cancer and a 42% lower risk of liver-related death. However, researchers said benefits were also seen in people who drank just one or two cups a day, with the strongest associations observed at around three to four cups daily.

MRI scans and blood tests also suggested coffee drinkers had healthier livers, with lower levels of fat, inflammation and scarring, as well as healthier protein markers linked to liver function.

The study found similar benefits for both caffeinated and decaffeinated coffee, suggesting compounds other than caffeine may play a role.

Researchers stressed that the study only found an association and does not prove that coffee directly prevents liver disease. They also said coffee should not replace proven ways of protecting liver health, such as maintaining a healthy weight, exercising regularly, limiting alcohol and managing conditions like diabetes and high blood pressure.
