People without a gallbladder need to reduce their fat intake and abstain from high-fat as well as fried foods. The main function of the unfed gallbladder is to store bile, and after eating, the bile will be discharged from the gallbladder into the intestines to help digest and absorb fatty foods. After gallbladder removal, the excretion and concentration of bile will be affected, which will affect the digestion of fatty foods and cause indigestion such as steatorrhea. Therefore, fatty foods such as barbecue and fried foods should be avoided as much as possible. It is recommended that a light diet high in protein and vitamins should be the mainstay, with fresh fruits and vegetables as well as fish and meat, etc. Steaming, boiling, stewing and processing of food should be preferred for cooking. It should also pay attention to the regularity of the diet, regularity, small and frequent meals.
