Here's another potential benefit of coffee: It may help reduce the risk of cirrhosis of the liver, according to a review of nine studies, published in Alimentary Pharmacology and Therapeutics. Worldwide, more than one million people die from this liver disease every year.
The new review found that the more coffee people drank, the less likely they were to develop cirrhosis, compared to their matched counterparts who didn’t drink coffee. Daily consumption of two cups of coffee was found to be associated with a nearly 50 percent reduction in the risk of cirrhosis.
It is “biologically plausible” that the caffeine and certain other compounds (such as chlorogenic acid, kahweol, and cafestol) in coffee could help protect against the inflammatory and scarring processes leading to cirrhosis, according to the British researchers.
The evidence for a protective effect from decaf is weaker but still plausible, they said.
