Kidney disease is a common disease, regardless of the cause (primary nephropathy, secondary nephropathy), if not effectively treated, after reaching a certain degree of kidney damage will occur renal failure, progressive and irreversible consequences. Ultimately, it results in uremia dialysis treatment to sustain life. Therefore, many patients with chronic kidney disease in the early and middle stages of renal failure are in urgent need of some therapeutic methods to delay as well as terminate renal failure. From the analysis of the current treatment methods, patients, in addition to the doctor’s regular medication and the combination of traditional Chinese and Western medicine treatment measures, dietary control dietary treatments, such as low-protein diet (LPD), which restricts the protein intake to 0.6/kg body weight, and maintains sufficient calorie supply, as well as limiting the supply of potassium, phosphorus, low-sodium, and low-purine diets, etc., can effectively delay the progression of the course of chronic renal failure. At present, through a large number of clinical studies at home and abroad, it has been confirmed that continuous dietary treatment can: 1) slow down the deterioration of renal function in chronic renal failure; 2) reduce the index of urea nitrogen and creatinine; 3) alleviate the effects of high potassium, high phosphorus and high purine on the body; 4) reduce the excretion rate of proteinuria; 5) improve the clinical symptoms of uremic renal failure. Continuous dietary therapy is an important part of assisting renal failure in chronic kidney disease that cannot be ignored. Therefore, dietary therapy and drug therapy have equal roles in alleviating the progression of renal failure. As a patient should pay attention to carry out scientific dietary methods and actively cooperate with drug therapy in order to maximize the protection of renal function to alleviate the deterioration of renal function. Patients with chronic renal failure, in order to prevent and control the deterioration of renal function at an early stage it is recommended to start dietary treatment before CKD-3 stage, the principles of low protein diet (LPD): 1, total amount of control: the total amount of daily intake of protein in patients with chronic renal failure, generally 0.6g/kg/day is appropriate. However, according to the degree of renal function damage and excretion of urinary toxins, the patient’s own nutritional status can be appropriately adjusted, such as renal function GFR (glomerular filtration rate) in more than 60 can be adjusted to 0.7g/kg/day, such as the GFR in less than 30 is adjusted to 0.5g/kg/day. 2.Limit the proportion of vegetable protein intake Generally for vegetable protein such as soy products, coconut milk, vegetable protein powder and so on to give restrictions to reduce consumption. 3.Reasonable distribution of protein intake in the daily meals Take starch food (special starch rice cakes, noodles, pastries) as the main food, and reasonably allocate meat, poultry, eggs, freshwater fish, shrimp, vegetables, fruits and other foods. Do try to be delicious to adjust the pattern can be accepted for long-term consumption 4, choose food containing phosphorus, potassium, purine, low fat food is appropriate Egg yolk containing phosphorus, fat more should not be eaten, in order to reduce the phosphorus in the food, the purine content of meat, fish, some vegetables with boiling water to cook and then abandon the water to eat is a kind of effective method. 5, must adhere to a sustained dietary regimen once the patient carries out the diet program, should continue to adhere to, so as to get a more significant effect. And combined with regular laboratory tests to check renal function, electrolytes, blood routine, plasma protein volume, lipids, proteinuria, etc. in order to further observe the efficacy and adjust the diet program. 6, pay attention to diet control, pay special attention to diet control, low-protein diet is effective for patients with early and mid-stage renal failure, as early as possible to carry out in order to benefit as early as possible. If patients enter the advanced stage of uremia, vomiting, diarrhea, dyspepsia, inability to ensure a normal diet, uremia comorbidities such as: pericarditis, peripheral neuropathy, severe hypertension can not be controlled, severe edema, plasma hypoproteinemia and a large amount of proteinuria, it is not appropriate to carry out the low-protein diet treatment.
