Protein diet in patients suffering from chronic renal failure

The treatment diet of kidney failure is to prevent and stop the progress of renal failure, slow down early lesions of renal function, a method which is most fundamental, the most effective. The most crucial is the entry of proteins, therefore, limit the intake of protein to ease the burden on the kidneys, reducing the production of toxins, relieve the condition of the disease, it plays an important role. The suggestion: the low protein diet reduce the generation and accumulation of metabolites of protein degradation, thus reducing the state high load of residual renal units, reduce the rate of glomerular filtration, slow the progression of glomerular sclerosis and chronic renal failure. Therefore, the low protein diet is an important means for treating patients suffering from chronic renal failure without dialysis. (1) It is generally believed that when the serum creatinine> 220μmol / L (2.5 mg / dl) or the rate of endogenous creatinine clearance should be 25-20 ml / min as follows, now, we must limit the intake of protein. (2) Entry of proteins of patients suffered from chronic renal failure per day should be limited to 0.5 to 0.7 g / kg. At the same time, adding essential amino acids or α-keto acid, to ensure the admission of suitable proteins. For patients already hemodialysis or peritoneal dialysis, protein intake is higher than the early stage of dialysis. Admission protein hemodialysis patients is usually controlled from 1.0 to 1.2 grams per day per kilogram of body weight up to dialysis three times a week, admission of proteins can be increased to 1.5 grams per day per kilogram of body weight. That peritoneal dialysis patients is 1.2 to 1.5 grams per day per kilogram of body weight. (3) low protein regime to ensure that 50% - 70% is of high quality protein, that is to say most of the main animal protein. Limit the proportion of vegetable protein intake. The protein-rich food quality is uniformly distributed over three meals a day, do not take a meal to facilitate absorption and utilization. Everyday food such as vegetables, fruits, noodles, rice, beer, etc.. containing proteins, the calculation of the admission of protein should be taken into account. (4) The intake of protein, no matter how limited, the nitrogen balance is also an important criterion to measure the demand for protein. For patients suffering from chronic renal failure, a long-term protein intake control 0.6 grams per day and per kilogram of body weight to maintain good nutritional status.
