Nuts are rich in several compounds that may protect against gallstone disease.
In this study, doctors from Boston evaluated the association between nut consumption and the risk of cholecystectomy in 80,718 women who had no history of gallstone disease.
The women completed questionnaires every 2 years.
The team found that during 1,393,256 person-years of follow-up (1980 to 2000) there were 7831 cholecystectomies.

They determined that women who ate 5 units of nuts (1 unit = 28.6g) per week had a significantly lower risk of cholecystectomy than women who never or rarely ate nuts.
When the consumption of peanuts and other nuts was analyzed separately, both were associated with a lower risk of cholecystectomy.
Dr Chung-Jyi Tsai and colleagues concluded, "In women, frequent nut consumption is associated with a reduced risk of cholecystectomy".
