To test the possible association between dietary factors and gallstones, we performed a case-control study on the dietary habits of 71 women with gallstones in a rural area of Sicily (mean age 63.2 years) and compared these with 142 women who did not have gallstones (mean age 63.6 years) selected at random from the same general population.
