To conduct their research, scientists used data from the United States National Health and Nutrition Examination Survey (NHANES 1999-2010). They selected 27,793 participants age 20 or older.

Volunteers filled out a survey about their coffee drinking habits and researchers tested their blood, measuring different markers for liver function. The purpose of this study was to measure the health of participants’ livers.

They discovered that those who drank three or more cups of coffee a day had lower liver enzyme levels compared to non-coffee drinkers.

Researchers also found that other compounds in coffee, besides caffeine, may promote liver health when consumed in moderation.

Drinking coffee may reduce your risk of fatty liver and fibrosis

A fatty liver and a normal liver.

Another study, also published in Hepatology, showed that drinking coffee may significantly reduce the risk of accumulating connective tissue in the liver (fibrosis) in patients who suffer from non-alcoholic fatty liver disease.

The study determined that the caffeine in coffee can reduce the accumulation of connective tissue in those suffering from chronic liver diseases, like fibrosis.

To conduct their study, researchers interviewed 306 people about their caffeine consumption and divided them into groups: patients without signs of fibrosis, those with steatosis, and those with non-alcoholic steatohepatitis (NASH) stages 0-1 and 2-4.

Patients with steatosis who drank coffee showed a significant difference in comparison with stage 0-1 NASH patients.

Coffee consumption was higher among NASH stage 0-1 patients with 58% reporting regular coffee intake as compared to 36% of stage 2-4 patients.
