Since gallstone patients should go on a low-fat diet to control fat intake and eat less fried and greasy food, it is recommended to eat less or no meat jelly. Since bile promotes the digestion and absorption of fat, when fat is ingested, it can cause the gallbladder to contract and secrete bile. When the gallbladder contracts, it can cause gallstones to irritate the gallbladder wall and cause pain, and when bile secretion increases, it can push gallstones to the gallbladder duct and cause blockage, so substances with high fat content may cause aggravation of the condition of gallstones. Meat jelly is processed from pork skin, which contains high fat content, so it is recommended to eat less or not eat meat jelly for gallstones. Gallstones patients should have a low-fat diet, such as eating less fatty meat, egg yolks, animal offal and so on. They should consume more food rich in high quality protein and vitamins.
