Coffee may surprise: scientists find link to liver cancer
The largest observational study of nearly 355,000 people found that regular coffee drinkers have significantly lower rates of cirrhosis and liver cancer. Scientists at Cedars-Sinai discovered that the effect is noticeable with just 1-2 cups, with the strongest association in the group drinking 3-4 cups per day. Even decaffeinated coffee showed a similar effect, suggesting that not only caffeine but also other compounds in the beverage play a role.
A large observational study conducted by scientists at the Cedars-Sinai Medical Center in the United States has found a link between regular coffee consumption and a reduced risk of cirrhosis and liver cancer. The study, published in the journal Clinical Gastroenterology and Hepatology, analyzed data from 354,957 participants in the UK Biobank, who were followed for 13 years. Coffee lovers who drank five or more cups per day had a 32% lower risk of liver cirrhosis, a 47% lower risk of liver cancer, and a 42% lower risk of death from liver disease compared to those who did not drink coffee. MRI scans showed that coffee drinkers had less liver fat, excess iron, scar tissue, and inflammation. Interestingly, even decaffeinated coffee showed a similar effect, indicating that not only caffeine but also other compounds are responsible. The authors emphasize that the study is observational and does not prove a direct causal relationship. Doctors do not recommend starting to drink coffee solely for liver protection, noting that it is more important to maintain a healthy weight, limit alcohol, and lead an active lifestyle.
