Coffee Study of 354,957 Links Daily Cups to Lower Liver Disease Risk

Summary
354,957 UK Biobank participants followed for a median 13 years showed a stepwise drop in cirrhosis, liver cancer and liver-related death among coffee drinkers versus non-drinkers, Dr. Hyun-Seok Kim reported.
2,970 cirrhosis cases, 342 hepatocellular carcinoma cases and 852 liver-related deaths were recorded, with the lower-risk pattern appearing in both caffeinated and decaffeinated coffee and also among sweetener users.
MRI and proteomic subgroups—28,961 and about 50,000 people—also linked coffee intake to lower liver fat, liver iron and fibroinflammation, suggesting possible biological pathways behind the association.
Diabetes appeared to blunt the benefit somewhat, and an outside expert said the cohort's lower artificial sweetener use and excessive alcohol intake than the broader UK population could mean healthier habits partly explain the findings.
Kim called coffee a low-cost intervention that may complement metabolic disease prevention, but the research was observational and does not replace standard medical advice on diet and liver health.
Why does coffee's liver-protecting magic nearly vanish for individuals who have diabetes?
This study hails coffee as a liver superfood, but could other healthy habits be the real hero?
Coffee Consumption Linked to Up to 47% Lower Liver Cancer Risk: New Evidence and Public Health Implications
Overview
A major 2026 Cedars-Sinai study revealed that coffee consumption is strongly linked to significant protection against severe liver diseases. This breakthrough advances our understanding of how diet can influence liver health, highlighting that coffee may help by affecting biological pathways related to inflammation and scarring. The findings have sparked further scientific research to identify which compounds in coffee are responsible for these benefits and to explore how coffee works at the cellular level. Researchers are also aiming to discover which individuals might gain the most from coffee’s liver-protective effects, paving the way for more targeted health recommendations.
