Diet for chronic renal insufficiency: 1. Low-salt diet If you have hypertension, swelling and poor heart function, it is advisable to limit salt and control salt intake to 2-3 grams per day (or 10-15 ml of soy sauce). Avoid foods containing sodium ions, such as salted vegetables, salted eggs, cured meat, seafood, salted bread, hanging noodles, etc. Low sodium salt can be consumed. It is mainly suitable for patients with kidney disease, hypertension, heart failure and edema. 2.High quality protein diet A diet based on eating high nutritional value protein (high quality protein), with high quality protein accounting for more than 50%. It is mainly applicable to kidney patients with normal kidney function. According to the nutritional value of protein in food, depends on the content and relative proportion of nutritionally essential amino acids in it. According to its nutritional value, protein can be divided into: (1) high nutritional value protein Mostly animal protein such as fish, lean meat, chicken, eggs, dairy products, animal protein contains more complete essential amino acids, easy to be used by the body, soy protein is the highest nutritional value of plant protein; (2) low nutritional value protein plant protein corn, wheat, rice in the egg fold, nutritional essential The content and ratio of amino acids differ greatly from human protein, and the human body has a low utilization rate. 3, high quality low protein diet daily diet of protein does not exceed 30-40 grams (adults), of which high-quality protein should account for more than 50%. Mainly applicable to patients with various chronic kidney disease. 4, low-fat diet Less animal oil, cooking oil mainly vegetable oil, limit cholesterol-containing food, such as egg yolk, animal offal, seafood, etc.. Mainly for hyperlipidemia, chronic kidney disease, hypertension, coronary heart disease, obesity and other patients. 5, low phosphorus diet Less animal offal, seafood, dairy products, meat and nuts. Mainly for patients with kidney failure, hyperphosphatemia. 6.Low purine diet Restrict the consumption of foods with purine content, such as animal offal, sardines, brains, gravy, hot pot soup, beer, etc. It mainly applies to patients with gout and hyperuricemia. If, after blood urea nitrogen, blood creatinine, endogenous creatinine clearing rate, renogram or ultrasound examination, it is determined that the patient’s renal function damage is not yet serious, it is not necessary to strictly restrict protein in the diet. Protein should be about 1 gram per kilogram of body weight per day, and attention should be paid to the selection of foods rich in high-quality protein, such as milk, eggs and lean meat. Calories should be maintained at about 2,000 kcal per day. You can also eat fresh fruits and vegetables to replenish a variety of vitamins, especially vitamin C. Tomatoes, cucumbers, heart radishes, various green leafy vegetables, fresh dates, watermelons, oranges, kiwis and natural fruit juices are rich in vitamins and minerals and can be selected appropriately. However, it should be noted that patients with chronic renal insufficiency should eat less fruits with high potassium, such as oranges and bananas, when eating fruits. The amount of salt should be decided according to the condition. When the patient’s swelling and hypertension are not serious, he can eat a diet with less salt. If the patient’s kidney function damage is becoming more serious, we should strictly limit the intake of protein and minerals such as sodium, potassium and phosphorus in the diet, and eat according to the chronic renal failure recipe.
