2017-02-10 15:02

(1) controlling potassium intake

Less urine or urine, we should strictly control the supply of potassium, water restrictions in the following 500ml/d, avoid eating foods containing high potassium, such as fresh mushrooms, letinous edodes, red dates, shellfish, beans, vegetables and fruits, etc..

(two) limit sodium and water

At the beginning of the disease, edema was the main symptom and the kidney could not excrete sodium. Drinking water and salt is a good way to eliminate edema. According to the condition, urine volume and edema, given low salt, no salt or low sodium diet. In addition to salt or soy sauce, avoid the use of sodium containing foods.

Edema and hypertension, should limit salt, 2 ~ 3g/d; severe edema, following control or given 2g/d salt, salt free diet, and regularly check the serum potassium and sodium levels, due to chronic nephritis polyuria or long-term sodium restriction will cause the content of sodium deficiency in vivo.

(three) low protein

Supply according to the condition that minor symptoms control in 20 ~ 40g/d, to reduce the burden on the kidney; low protein diet should not be too long, to prevent the occurrence of anemia. Once the blood urea nitrogen and creatinine clearance rate is close to normal, whether or not proteinuria, protein supply should be gradually increased to 0.8g/kg per day, in order to facilitate the repair of renal function. Selection of essential amino acids, rather than essential amino acids less high-quality protein, such as eggs, milk, lean meat and fish, etc., should not eat beans and their products.

According to the degree of renal impairment to determine protein intake, long course of disease, if the kidney damage is not serious, do not have to strictly limit the protein in food, every day should not exceed 1g/kg, including more than 50% high quality protein. When the disease is restricted by the disease.

(four) carbohydrate and fat

Most of the carbohydrate diet heat supply, add enough carbohydrates, can prevent the energy shortage, also make the food supply a small amount of protein completely used for tissue repair and growth; should add dessert, vermicelli, bean etc.. Do not need to strictly limit the amount of total fat, but less animal fat and oil containing more fried food. Acute nephritis is often accompanied by hypertension, should not eat animal fat, to prevent elevated blood lipids; increasing the dessert, carbohydrate containing high vegetable diet to light is better.

(five) heat energy

In the treatment of rest, drugs and dietary therapy combined with serious need to rest in bed, so the energy consumption is reduced, less activity decreased appetite, daily supply of heat without too high, by 0.10 ~ 0.13MJ (25 ~ 30kcal) /kg, all day long to 6.69 ~ 8.37MJ (1600 ~ 2000kcal).

(six) provide enough vitamins

More fresh green leafy vegetables and fruits. Fresh vegetables can improve the patient's appetite, except in oliguria period limit potassium, vegetables should be restricted; otherwise we should give fresh vegetables. The recovery period can be supplied to a plurality of yam, red dates, longan, lotus seeds, white fungus nourishing food. Vitamin A, vitamin B, vitamin C, folic acid, vitamin B1 and iron, are conducive to the recovery and prevention of renal anemia, adequate food supplement should be optional; slip cabbage, tomato fried egg vinegar fried carrots, food etc..

(seven) restricted irritant food

Limit the spices and excitant food, such as metabolites of fennel, pepper and other food containing purine excreted by the kidneys, can increase the burden of kidney, therefore, should not eat; animal liver, kidney and other organs containing nuclear protein, its metabolites containing purine and uric acid also, also should eat less.

(eight) supply more alkaline food

Uric acid was found in acute glomerulonephritis, and the pH of food could regulate the pH value of urine. The supply of alkaline food, so that urine near neutral, conducive to treatment. Oliguria should limit potassium containing more fruits and vegetables, to prevent the occurrence of hyperkalemia.

(nine) the principle of changing diet

Acute exacerbation of chronic nephritis, according to the principles of treatment of acute nephritis diet, a large number of proteinuria, should be treated according to the principles of dietary treatment of nephrotic syndrome. In short, the chronic nephritis should be closely combined with changes in the disease, diet formula, in order to improve the stability and recovery.
