novapsycheCoffee May Lower Women's Gallstone Risk
Women who down lots of coffee may get more than a buzz--new research suggests they may also be cutting their risk of gallstones.
The large study of US nurses found that women who drank at least four cups of caffeinated coffee each day were about 25% less likely to need surgery for gallstones than non-drinkers were. This pattern has previously been found in studies of men.
[...] The investigators did not discover the same potential protective effect from tea, although they note that they were unable to distinguish between tea that did or did not contain caffeine. And in contrast to the coffee findings, they found that women who drank the most caffeinated soft drinks appeared to have a higher risk of gallbladder surgery than did women who drank the least.
