Health: Coffee protects against gallstones

UNITED STATES, WASHINGTON (OBSERVATORY) — According to a new international study, drinking large amounts of coffee helps reduce the risk of gallstones.

The data of 104,493 people over 38 years were studied. Those who drank more than six cups of coffee a day had a 23% lower risk of developing symptomatic gallstone disease than people who did not drink coffee.

On average, each cup of daily coffee helped reduce the risk of gallstones by 3%. In addition, people with certain genetic variants associated with increased coffee consumption had, in principle, a lower likelihood of gallstones.

The study revealed not only a correlation: using Mendelian randomization, scientists found that the relationship between high coffee consumption and low risk of gallstone disease is actually a causal one. Communication mechanisms are currently under discussion.
