Diet for Patients with Renal Failure in Advanced Stage

Diet for patients with renal failure in advanced stage who are not under dialysis is as follows:
1. Keep low salt diet. Generally, patients should take in 2 to 3g salt every day. However, those who have severe edema, high blood pressure or heart failure should keep the intake of salt under 1g. After urine increase or edema disappears, the intake of protein can turn 2 to 3g.
2. Avoid food which is rich in potassium. Disorder of potassium metabolism is common, which should be adjustment immediately or else it will damage heart as well. Food which is rich in potassium is such as tomatoes, cabbage, garlic, fresh mushroom, kelp, peach, date, bananas and so on.
3. Avoid food which is rich in phosphorus. Usually, in advanced stage of renal failure, patients are in high phosphorus state. At the same time, long time declined absorption of calcium of guts lead to high phosphorus and low calcium. Long time intake of food rich in phosphorus can also lead to the unbalance of calcium and phosphorus. Food rich in phosphorus is such as sea food, internal organs of animals, peanuts, nuts, egg yellow, tea and so on.
4. Keep low protein intake. Patients in advanced stage of renal failure should take in good quality protein such as lean meat, egg white and milk, etc. The total intake of protein should be not more than 20 to 30g. For those whose renal function deteriorates, they should control the intake of food more strictly according to Ccr. If Ccr is less than 5ml/min, the intake of protein should be 18 to 20g per day. If Ccr is 5 to 10 ml/min, the intake of protein should be 20 to 25g. If Ccr is more than 10, the intake of protein should be at 25 to 35g per day.
5. Keep low fat diet.
