This article has some suggestions, excerpted below:
What to eat:
“Include foods in your diet that promote the good health of your biliary system and your digestive system in general. Fiber sources such as lettuce and grains are wonderful, as are vitamin-rich fruits and vegetables such as beets, tomatoes, cucumbers, avocados, grapes and carrots. Foods high in Omega-3 fatty acids such as flax-seed oil and salmon are also beneficial.”
What not to eat:
“Avoid foods that have a high fat or acid content. Until your body has had time to heal and adjust, stay away from red meat, pork, butter, fried foods, dairy products and eggs. In regards to drinks, stay away from fruit juices (aside from grape and apple) and all caffeinated, alcoholic or carbonated beverage. Even decaf coffee and tea should be avoided.”
