Although there is no obvious dietary contraindications for gallstones, but if you eat a lot of crabs can lead to gallstone attacks, so eating crabs need to be moderate, and it is best to take steamed, boiled cooking method. It should be noted that, in addition to crabs, animal offal, fatty meat, as well as fried food, hot pot, etc., should also try to avoid eating. In normal life, it is still necessary to maintain a light and regular diet.
