Moderate amount of coffee can prevent cholelithiasis

Harvard University researchers found that men who drank two or three cups of coffee a day were 40 per cent less likely to get gallstones than those who did not drink coffee, while drinking more than four cups of coffee a day, Harvard University researchers found that men who drank two or three cups of coffee a day were 40 per cent less likely to get gallstones than non-coffee drinkers, according to the Journal of the American Medical Association. The chance of getting gallstones dropped to 45.

However, non-caffeinated coffee can not have this effect, only caffeinated coffee can stimulate gallbladder contraction and reduce bile content easy to form gallstone cholesterol. As for the reason for the effect of coffee, it is not clear, while other drinks such as tea and cola, which also contain caffeine, cannot achieve the same effect because their caffeine content is lower than that of coffee.

Dr Leizman, who led the study, said: I wouldn't really recommend coffee to prevent gallstones, but it doesn't hurt to keep drinking it because it doesn't cause any major disease. He said the findings should also be valid for women. Gallstones are mainly caused by cholesterol, and lack of exercise, greasy diet or overweight are the main causes.
