Renal failure diet control principle

2017-01-25 16:42

Chronic renal failure patients with a reasonable diet, help to reduce the retention of metabolic waste, delaying the 

progression and deterioration of chronic renal failure.

 

First, the protein intake

(a) the principle of high quality and low protein.

Try to limit the intake of vegetable protein in the staple food, you can use wheat starch instead of some ordinary flour, rice.

 Intake of animal protein, such as eggs, milk, lean meat, etc., require such high-quality protein accounted for more than half of the total protein.

(two) intake

1 patients without dialysis control protein intake in order to reduce the production of nitrogenous metabolites, delay the 

progress of the disease, while preventing malnutrition.

When a kidney damage, while serum creatinine was normal, no obvious symptoms, should also limit the intake of protein, about 

0.8g/kg.d; the serum creatinine is less than 450 umol/l, protein intake 0.6g/kg.d, adding alpha keto acid or essential amino 

acids; the serum creatinine greater than 450 umol/l, the protein quantity of 0.4 0.6g/kg.d, at the same time add alpha keto 

acid or amino acid.

Patients with diabetic nephropathy, as long as the emergence of proteinuria (24 hours urine protein greater than 300 mg), that

 should limit the intake of protein, about 0.8g/ kg.d. When serum creatinine rises, the protein intake should be controlled by

 reference to the above criteria.

2 dialysis patients with hemodialysis, protein intake 1.2g/kg.d. Peritoneal dialysis patients, protein intake of 1.2 1.3g/kg.d

, while adding a-ketoacid preparation 0.075-0.12g/kg.d.

[note] low protein diet, should ensure adequate intake of calories, to avoid the use of protein decomposition.

 

Two, carbohydrate intake

The first is to ensure adequate heat, caloric intake is 30 35kcal/kg.d, about 55-60% calories from carbohydrate supply (such 

as 60kg 1800 kcal weight patients need heat heat, intake of rice or flour is about 270g), may be appropriate to eat more 

calories and protein containing relatively low food, such as potatoes, sweet potatoes, yam, taro, lotus, water chestnut, 

pumpkin, vermicelli, lotus root starch, water chestnut powder, rice flour, instead of part of. Increase the amount of sugar 

or vegetable oil when the intake is reduced to increase the heat.

 

Three, salt intake

Principle is a low salt diet.

(a) without hypertension, edema, heart failure, ascites or pleural effusion, general salt 5 g / day;

(two) patients with hypertension or heart failure, oliguria, severe edema in patients with dialysis whether or not, should

 strictly control the amount of salt or salt free diet, daily general does not exceed 1 2g;

(three) patients with normal dialysis, urine volume of normal without complications, can not control the amount of salt,

 according to the ordinary diet treatment.

[note] sodium intake in addition to salt, including food and drug containing sodium, such as pickled foods, monosodium 

glutamate, sodium bicarbonate.

Three, salt intake

Principle is a low salt diet.

(a) without hypertension, edema, heart failure, ascites or pleural effusion, general salt 5 g / day;

(two) patients with hypertension or heart failure, oliguria, severe edema in patients with dialysis whether or not, should 

strictly control the amount of salt or salt free diet, daily general does not exceed 1 2g;

(three) patients with normal dialysis, urine volume of normal without complications, can not control the amount of salt, 

according to the ordinary diet treatment.

[note] sodium intake in addition to salt, including food and drug containing sodium, such as pickled foods, monosodium 

glutamate, sodium bicarbonate.

 

Four, low phosphorus high calcium diet

Patients with chronic renal failure have low calcium and phosphorus. In addition to relying on drugs to supplement calcium,

 but also on the diet every day to supplement 1000-1500 mg of calcium. Milk, lean meat, egg white, etc. are rich in calcium.

At the same time should avoid intake of high phosphorus foods. A variety of fish and other aquatic products, animal offal, 

beef, lamb, rice, chicken, walnuts, sunflower seeds, peanuts and other high phosphorus.

Five, high vitamin diet

Vitamins are essential to the human body. Most vitamins cannot be synthesized in the body, dependent on food intake. Patients 

with chronic renal failure should be a daily supplement of folic acid 5 mg, vitamin C0.5 mg, vitamin B6 mg 5-10. Vitamin D 

dosage according to the clinical needs, can not be used in the early stage of renal failure, uremia period will be used. 

Vitamin A levels are elevated in patients with chronic renal failure.

Six, water control

When kidney failure and reduce urination, water will accumulate in the body and the cardiovascular system load increases,

 systemic edema, weight gain, shortness of breath while lying down, and hypertension, heart failure, pericarditis, and dialysis 

due to excessive dehydration, prone to headaches, nausea and vomiting, weight gain is limited to no more than a day one kilogram,

 and the amount of water for the day before the total amount of urine with 500-700ml. All day long drink water, including boiling

 water, milk, soup and drink Rice porridge.
