In principle, patients after liver transplantation should be given a light, easily digestible diet, which should be supplied with sufficient calories, and a diet high in vitamins and appropriate protein, such as fruits, vegetables, soy products, dairy products, lean meat, fish, etc. When cooking these foods, try to avoid the application of frying. The diet should also be careful to avoid spicy, cold, high-fat, greasy and indigestible foods such as chili peppers, animal offal, egg yolk, fatty meat, etc. If esophagogastric fundic varices are already present, avoid eating rough and sharp foods, such as nuts and pancakes. Pay attention to immunity-enhancing foods that may cause postoperative rejection, so mushrooms, ginseng, royal jelly, etc. should not be consumed; pay attention to controlling the intake of sugar and sodium to avoid diabetes or increased ascites.
