Walnuts cannot treat gallstones and can aggravate and induce gallstones and cholecystitis. Patients with gallstones usually need a light diet with fresh vegetables and fruits and a low-fat diet to reduce the need for bile acids because of the reduced contractile function of the gallbladder and the imbalance between cholesterol and bile acid dissolution. Walnuts are part of a high-fat diet, so they can aggravate gallstones cholecystitis or induce acute cholecystitis. Gallstones are mainly associated with cholesterol, bile acid dissolution imbalance, biliary tract bacterial infection, and gallbladder contraction hypofunction. Gallstones can induce acute cholecystitis and even jaundice, chills and fever symptoms. Bile acid bile is produced from the liver, concentrated by the gallbladder and discharged to the intestinal cavity via the common bile duct, mainly involved in the digestion and absorption of fats.
