The diet should be rich in vitamins, especially B vitamins, vitamin C and folic acid. These vitamins are mostly found in fruits and vegetables, such as tomatoes, rape, leeks, oranges, hawthorn and so on. Fresh vegetables and fruits should be added to the daily diet.
2, high calorie intake.
Intake enough carbohydrates can provide enough calories for human body, reduce the decomposition of protein to provide calories, improve azotemia, and make full use of amino acids in low-protein diet. The daily calorie requirement is about 125.6j/kg, which is obtained by daily intake of staple food, mainly supplied by cereals such as rice, wheat and corn rich in carbohydrates. In addition, it also exists in sweet potatoes, taro, potatoes, apples and lotus roots.
3. Restrict protein's diet.
Reducing the content of protein in diet can improve azotemia and reduce the damage of proteinuria to kidney. It is also beneficial to reduce blood phosphorus and acidosis, because the intake of protein is often accompanied by inorganic acid ions such as phosphorus. Generally speaking, 0.6/kg protein per day can meet the physiological needs of the body, and 30-36g protein per day is enough. The choice of food in protein should be mainly fish, lean meat, chicken and milk. Try to eat less substances containing plant protein, such as peanuts, soybeans and bean products, because plant protein contains many non-essential amino acids. Eating too much in nutrition supply will not help, but will aggravate the phenomenon of urinary protein.
