Coffee improves liver health.

coffee1A study, published in the journal Hepatology, has specified that caffeinated and decaffeinated coffee may benefit health. Higher coffee consumption regardless of caffeine content was linked to lower levels of abnormal enzymes suggesting that the compounds in coffee may protect the .

It is estimated that 50% of Americans drink three cups each day on average. Prior has touted the of coffee including protecting from diabetes, , non-alcoholic , cirrhosis, and cancer.

The participants for this study included 27,793 participants, 20 years of age or older, who provided coffee intake in a 24-hour period. The team measured blood levels of several markers of function, including aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP) and gamma glutamyl transaminase (GGT) to determine health.

The findings revealed that study participants who reported drinking three or more cups of coffee per day had lower levels of ALT, AST, ALP and GGT compared to those not consuming any coffee. Researchers also found low levels of these enzymes in participants drinking only decaffeinated coffee.

“Prior found that drinking coffee may have a possible protective effect on the . However, the evidence is not clear if that benefit may extend to decaffeinated coffee,” explains lead Dr. Qian Xiao from the in Bethesda, Maryland.

Dr. Xiao concludes, “Our findings link total and decaffeinated coffee intake to lower enzyme levels. These data suggest that in coffee, other than caffeine, may promote health. Further studies are needed to identify these components.”
