Good dietary control after kidney transplantation not only provides patients’ quality of life, but also delays the decompensation of transplanted kidney function and reduces complications caused by anti-rejection drugs. Water: Kidney transplant patients should drink more than 2000ml of water per day, and if oliguria (urine volume less than 400ml/day) occurs, the amount of water drunk in a day should be 500ml to 750ml plus the total urine volume of the previous 24 hours. Salt: It is necessary to limit salt intake except during the postoperative polyuria period. Generally, salt intake should be 3g to 4g per day, but in case of no edema and no hypertension, strict restriction is not necessary, and less than 6g per day as recommended by WHO is sufficient. Carbohydrates: including cereals, rice and bread. Due to the application of corticosteroids and other drugs, excessive intake of sugar products can cause drug-related hyperglycemia. Therefore, high sugar intake must be avoided. The recommended carbohydrate intake is 150g to 250g/day. Pumpkin, potatoes, yams and yams help to lower cholesterol. Protein: The daily intake during the postoperative recovery period is 1.2g to 1.5g/kg body weight. High-quality proteins such as meat, eggs, fish and poultry should be consumed, and less vegetable proteins such as soy products should be consumed. Fat: Kidney transplant patients should have a light diet, avoid greasy, do not eat fried food, and limit the intake of high cholesterol foods, such as animal offal, egg yolk, crab yolk, fish roe, pig’s feet, meat skin, chicken skin, etc. It is recommended to use “white meat” such as chicken and fish, and to consume less “red meat” such as beef, lamb and pork. Calcium: You can intermittently eat calcium-rich foods such as milk, rib soup, etc. to prevent osteoporosis. Adding vinegar when boiling soup can increase the dissolution and absorption of calcium. In addition, calcium supplementation should not be excessive, otherwise it will increase the burden on the kidneys. In addition, kidney transplant patients should also change their habits, advocate a small number of meals, eat more leafy greens, avoid gastrointestinal irritants such as coffee, tea, etc., and quit smoking and alcohol.
