Coffee is one of the most popular drinks on the planet, and the good news is that a newly published report says it may reduce the risk of liver disease by 70 percent. You may want to put the kettle on before you read the rest of this.
Mud, dirt, java, liquid energy, cupped lighting, jitter juice — whatever you call it, coffee has long been a favorite mug-filler for humans.
Here at Medical News Today, we always cover research that involves coffee because you folks out there in MNT-land seem to be fascinated. I guess we all want to know whether this black gold we pour into our mouths every few hours is a blessing or a curse.
Over the years, we’ve charted its ups, downs, and falls from favor, but according to the latest report, our daily fix could be a lifeline for our livers.
This latest batch of good news comes fresh from a roundtable event, which was held at the Royal Society of Medicine in London in the United Kingdom. The event was chaired by Prof. Graeme Alexander, a senior advisor to the British Liver Trust, from University College London.
Also involved were media medics, academics, and representatives from liver associations across seven European countries, all of whom discussed current issues and challenges and mulled over the latest research regarding coffee and the liver.
Chronic liver disease is one of the most common disease-related causes of death in the United States. An estimated 31,000 U.S. individuals die from cirrhosis each year. Worryingly, liver disease appears to be on the rise in the Western world, too. This is primarily due to excess alcohol, calorie, and fat intake.
One of the major concerns debated at the event is that most people with liver disease are unaware that they have a problem. And, although the liver is a vital organ, it is not often seen as such a high priority as the heart.
Against this stark backdrop, the latest report brings some welcome relief: that cup of joe you’re holding might go some way toward saving the day. Prof. Alexander explains the importance of these talks.
He says, “Liver disease is on the rise across Europe, and it is important that we understand how coffee, one of the most popular drinks in the world, and diet affects the disease.”
“Research suggests that coffee,” Prof. Alexander notes, “may reduce the risk of liver diseases and it is important patients have access to dietary information and advice from healthcare professionals in a manner that is easy for them to understand and act upon.”
Among the research papers discussed were a number of positive
It is thought that liver cancer often develops from an existing problem with the liver. Therefore, this reduction in risk may be due to its protective effect on the liver overall.
To add to this ever-growing list of liver ailments eased by coffee, some studies looked at its effects on non-alcoholic fatty liver disease (NAFLD). Again, the findings were positive.
Some of the studies focused on coffee consumption and chronic liver disease in general. Again, the coffee drinkers seemed to come up trumps with an average risk reduction of
It is possible that some of the positive results have been partially skewed.
However, the effect is so strong across numerous studies that this could not account for the entire association.
Because liver disease is increasing in the Western world, these findings are incredibly valuable.
“Liver disease is a silent killer as often there are no symptoms until it’s too late. Coffee is something that is easily accessible to everyone and regularly drinking it — filtered, instant, or espresso — may make a difference in preventing and, in some cases, slowing down the progression of liver disease — it is an easy lifestyle choice to make.”

The exact mechanisms behind coffee’s protective role are not understood, but there are some theories being bounced around. Caffeine, one of coffee’s major players, might be involved. In particular, paraxanthine — one of caffeine’s main metabolites — has come under the spotlight.
It suppresses the synthesis of connective tissue growth factor, which slows down connective tissue growth. This, in turn, may decelerate the development of liver fibrosis, alcoholic cirrhosis, and liver cancer.
One problem with this theory is that tea drinking does not seem to impart the same miraculous benefits to the liver, so perhaps this is not the entire story.
Other researchers have pointed their fingers at other constituents of coffee — namely,
Whatever the mechanism, as far as your liver is concerned, coffee can do no wrong. That being said, it’s important to chuck in a couple of important caveats: caffeine is not safe for everyone.
As Yella Hewings-Martin, Ph.D., explains in MNT‘s dive into coffee and health, “The groups most at risk of potential negative effects from caffeine consumption include […] expectant mothers and lactating women, children and teenagers, and possibly patients with underlying conditions.”
But, if you’re not in an at-risk group, having a few cups every day might be just what your liver wanted for Christmas.
