Researchers from the University of Southampton and the University of Edinburgh have found that it’s possible that the more coffee you drink, the less likely you are to develop hepatocellular cancer (HCC) — the most prolific form of liver cancer. Analyzing data from 26 studies, which involved more than 2.25 million participants in total, they concluded that people who drink 1 cup of coffee per day have a 20% reduced risk, 2 cups per day reduces risk by 35%, and 3 cups per day decreased risk by 50%. These findings showed that decaffeinated coffee also affects your risk, but the team could not deduce the precise amount.
Lead author Dr. Oliver Kennedy, a member of the Primary Care and Population Sciences Faculty of Medicine at the University of Southampton, told The Guardian: “Coffee is widely believed to possess a range of health benefits, and these latest findings suggest it could have a significant effect on liver cancer risk.” Coffee has also been said to have painkilling capabilities and the potential to prevent heart attacks.
The main consequence of this study is that doctors may be able to use coffee to help in the prevention of liver cancer. It’s a step that is both inexpensive and easy for people to incorporate into their daily lives, if they haven’t already. These benefits are also present in decaffeinated coffee, meaning that this means of prevention would also be accessible to those who can’t or do not drink caffeinated coffee.
The study authors wrote “It may be important for developing coffee as a lifestyle intervention in chronic liver disease, as decaffeinated coffee might be more acceptable to those who do not drink coffee or who limit their coffee consumption because of caffeine-related symptoms.”
Now, this development is not necessarily an encouragement to drown yourself in Starbucks. There are dangers in consuming too much caffeine, and much more research still needs to be done before coffee can be used medically with certainty. There is not enough existing research into the possible repercussions of consuming large quantities of caffeine over time, especially as a preventative medical measure. Hopefully in the future, preventing liver cancer will be cheap, easy, and delicious.
