What foods do you recommend for biliary tract disease?

Low-Fat: The most common biliary tract problem is gallbladder disease. Fatty foods tend to precipitate gallbladder attacks because fat in the stomach releases a hormone, cholecystokinin, that stimulates gallbladder contraction. Of course, not everybody "follows the book": some people will get attacks after eating any food or even when fasting. This problem is easily solved by surgery, though.
