Nephropathy patients need high-quality protein diet, which is the high-quality protein? Understand these will facilitate your diet.（part 1）

The pros and cons of a protein is determined by the type and amount of amino acids in the protein's composition. In the general, the high-quality protein have three characteristics:

1. Easily digested by the body.

2. After being absorbed by the body has high utilization.

3. Contained the essential amino acids are abundant,complete in variety, proper proportion.

At the same time the amino acid utilization rate of the protein is high, the ratio of various amino is acids accord with the ratio of human protein amino acids.  A lot of animal protein, such as fish, chicken, milk, eggs contained in the protein, are high-quality protein. Soybean in vegetable protein, kidney disease patients can edible ( Can check out the latest nutritional standards for chronic kidney disease dietary guidance) . Eating these high-quality proteins can reduce the excretion of proteinuria in patients with kidney disease, reduce glomerular hyperfiltration state, thus reducing kidney damage.

Daily protein intake: Standard body weight × Daily protein intake per kg body weight= Daily protein intake. Chronic kidney disease GFR<80 ml/min, it is recommended protein intake 0.6g/Kg day.

For example: Patient body weight with 65 kg, daily protein intake is: 65×0.6=39g. It should be noted that, of which high-quality protein should account for more than 50%.

1. Chronic kidney disease(Chronic nephritis) compensatory stage of renal insufficiency, (50 ml/min<GFR<80 ml/min, serum creatinine <130μmol/L) daily protein intake of patients, 0.6g/Kg (Which high-quality protein 0.4g / Kg)

2. Nephrotic syndrome protein turn negative don't have edema and kidney function is normal (GFR>80ml/min) protein intake can be give normal diet; A large number of proteinuria, edema, normal renal function(GFR>80ml/min) daily protein intake: 1.0g/Kg(Which high-quality protein 0.6g / Kg).

3. Renal insufficiency azotemia period (FR25-50 ml/min,130μmo /L< serum creatinine ≤450μmo/L). Daily protein intake: 0.5g/Kg  (Which high quality protein 0.3g / kg).

4. Renal insufficiency renal failure period (GFR10-20ml/min，450μmol/L< Serum creatinine ≤707μmol/L) Daily protein intake 0.5g/Kg (Which high quality protein 0.3g / kg).

5. Renal insufficiency uremia period (GFR<10ml/min, Serum creatinine >707μmol/L) not dialysis patients. Daily protein intake:0.5g / kg (Which high quality protein 0.3g/kg).

6. Renal insufficiency uremia period (GFR<10ml/min, serum creatinine >707μmol/L) Strengthen dialysis more than twice a week or every other day once. Daily protein intake 1.0g / kg. (which high quality protein 0.6g/Kg).
