☕ Coffee and the liver is one of the most consistent findings in nutrition research, and it does not seem to be the caffeine.
A UK Biobank study of more than 355,000 adults, published in Clinical Gastroenterology and Hepatology in July 2026, followed people for about 13 years.
Compared with none, 5 or more cups a day was linked to 32 percent less cirrhosis, roughly half the liver cancer risk, and 42 percent fewer liver related deaths.
Decaf showed a similar pattern, which points at chlorogenic acids and other compounds rather than caffeine.
An earlier meta analysis found any coffee at all was tied to about 39 percent lower cirrhosis risk.
This is all observational, so other habits could explain part of it.
One trade off worth knowing. Unfiltered coffee keeps compounds that raise cholesterol.
Paper filters remove most of them.
