When it comes to kidney disease, most people know to the control diet, but how to control, may not understand. Department of Nephrology experts, the most basic should be low salt and low-fat diet, because salt intake, lipid metabolism disorders can increase the burden on the kidneys, usually recommended daily intake of 6 grams of salt, but if there is edema or high blood pressure, can be the minimum to 3 grams per day. Control of low salt also have a protective effect on the cardiovascular changes. Dietary inorganic salt supply to the disease with the timely adjustment.

In addition to low salt, low fat, and the most important thing is the high quality low protein diet, patients should limit dietary protein intake, and as much as possible to improve the proportion of high-quality protein, at least 50% of the total intake to 70%.

Although the need to limit the intake of protein, but still adequate energy intake, daily intake of 30-35 kcal / kg body weight, high quality protein foods throughout the day shall provide on meals, so as to reduce the burden on the kidney, and can ensure the body better absorption and utilization. In addition, vitamin supplement should be enough, once the amount of urine reduce edema when water intake should be limited.

"Restrict protein diet" is the treatment of chronic kidney disease, especially an important link of chronic renal failure. Low protein diet can reduce the excretion of urine protein, renal protein, amino acid metabolism burden, retarding the rate of renal dysfunction, delay into the dialysis time.

In 2010 the American Society of Nephrology launched chronic kidney disease needs the recommended standard, China also proposed chronic kidney disease especially after the 3 period, the recommended kidney should be changed into a low protein diet. One of the important mechanisms of chronic kidney disease caused by the sustainable development of the "three high", namely high filtration, high perfusion and high pressure, low protein diet can also reduce the three high on the mechanism, delaying the progression of kidney disease.

However, edible protein low protein diet is not, but is necessary to ensure adequate intake of protein, not caused by malnutrition, and not cause too much burden to the kidney, only than the normal intake standard is low. The protein intake should be based on age, gender, weight, height, renal function and physiology and pathology to determine.

The amount of protein with non dialysis for 0.6-0.8g/kg/d, what is this concept? For example, 60 kg weight, at 0.8, daily 48 grams of protein intake may include: an egg (7 grams), 250 ml of milk (9 grams), one or two meat (8 grams), 24 grams of total protein 50%, plus half a catty of vegetables per day (4 grams), the remaining 20 grams of staple food, about 5 in two. But if you need to control protein intake can reduce further, but the common staple food, in order to ensure that heat can be exchanged for wheat starch.

So what are the requirements of the diet for chronic kidney disease? Zhang Kun pointed out that the body's intake of protein is mainly from the diet, and that patients should be reasonably combined with cereals and legumes

Plant proteins are mainly cereals and legumes. The content of protein in cereals is about 10% and the content of protein is not high. However, cereals are still an important source of dietary protein in our country due to the characteristics of dietary patterns in our country

Legumes are rich in protein, and the amino acid composition is reasonable. It is a good protein in plant proteins

In addition, animal protein contains essential amino acids, this kind of food such as egg white, milk, beef, poultry, fish, nutritionally superior to plant protein. Fruits and vegetables contain a lot of water, but the protein and fat content is very low, therefore it cannot serve as a source of protein.

Specifically, the sources of available proteins are as follows:

Meat (animal protein)

Patients with renal failure, should limit the intake of protein. Because of its in vivo metabolism can produce some nitrogenous waste, and through the kidney with the urine. This is not to eat meat, on the contrary, meat, egg, milk contains high biological value of protein, being absorbed by the human body must be a high degree of uptake the animal protein contains essential amino acids. More high bioavailability. As long as the daily intake does not exceed the recommended weight on the line. A vegetarian diet is containing plant protein, does not belong to the high protein, eating too much will produce too much nitrogen waste, but increased the burden on the kidneys.


Egg proteins contained a complete protein our body needs most, the fat, iron, calcium, and easily absorbed by the body. The egg is rich in vitamin A, vitamin B2, vitamin B1 and so on, we are in urgent need of body and trace element lack. Egg in the prevention of atherosclerosis, a the effects of cancer and other aspects, the egg protein can repair damaged liver, lecithin can promote the regeneration of liver cells.


Milk is a good protein food (8g/250mg); milk is a good source of calcium (260mg/250g); milk has moderate levels of phosphorus (183mg/250g)

Bean Products

The traditional idea that the soybean plant protein, renal failure patients can not eat. The low bioavailability of plant protein, non essential amino acid that contains more leads and excretion of nitrogenous substances more easily after ingestion, increase the burden on the kidneys. But recent studies have shown that soy protein as high biological value of complete protein, digestion and absorption rate 84% ~ 98%, and compared with animal protein, soy protein on renal blood flow and glomerular filtration rate had no obvious effect. In addition also has antioxidant, hypolipidemic, antihypertensive peptide and so on.

The first phase of chronic kidney disease, phase two recommended protein intake of 0.8g/ (kg.d)

The third phase of chronic kidney disease recommends protein intake of 0.6-0.8g/ (kg.d)

The recommended protein intake in phase fifth and phase fourth of chronic kidney disease was reduced to 0.4-0.6g/ (kg.d)

In low protein diet, about 50% protein should be high biological protein

In order to facilitate the selection of patients for patients with three meals a day, we designed a rapid method of low protein diet. The patient assumes the acceptable daily intake of 40 grams of protein, as long as the follow 5 principles of 1 can be easily done: 1 bags of milk, 1 egg, 1 two meat, 1 pounds of melons and vegetables; and then choose 2-3 two common staple food according to the energy needed to choose starchy foods and high quality vegetable oil to supplement the lack of energy, you can easily achieve a low protein diet "

Experts say, "also need to be reminded that chronic kidney disease drugs to control the primary disease, reduce proteinuria, promote intestinal detoxification, protect renal function, mainly to reduce the burden on the kidney. At present there is no special or cure" God medicine ", especially the unscrupulous websites widely publicized, so we can not listen to superstition or advertising, scientific treatment, Health Sciences, science and health is the most important, the most effective way"
