Laparoscopic cholecystectomy has been widely used, and this surgical procedure is the most suitable surgical method for treating benign gallbladder diseases (cholecystitis, gallbladder stones, gallbladder polyps) with few complications, little trauma and exact results, but after removal of the gallbladder, attention to dietary regulation is still needed . The normal gallbladder has the functions of storage, concentration, bile excretion and secretion. After the removal of the gallbladder, the body loses the above-mentioned functions of the gallbladder. The problem of fat digestion is that there is no concentrated gallbladder bile entering the small intestine, the concentration of bile acids in the intestine does not reach the critical microcolloid concentration, and the content of bile salts is reduced by half compared with normal people. However, after a period of time, the body will gradually adapt and compensate, and this process takes 2 – 3 months. Therefore, during this period of adaptation, the intake of fat should be limited, especially not to eat food containing too much animal fat at one time. Generally, small and frequent meals are used, and one meal should not be too full. Food content can be low-fat semi-fluid or low-fat soft meals. Such as a variety of porridge, noodles, pasta, bread, cookies, tofu, egg whites, fat-free milk and low-fat lean meat, less fiber vegetables, fruits, etc.. Cooking with stewing, steaming, boiling and blanching to make the food soft and less oily is appropriate.
