Patients with kidney disease can only be vegetarian?

Diet management is an extremely important part of the treatment of chronic kidney disease. Many nephrologists put it in the same position as drug treatment. "Managing your mouth and opening your legs" is not only for diabetic patients, but also for patients with chronic kidney disease. Very important. However, there are three common dietary misunderstandings in patients with kidney disease.

Misunderstanding 1: People with kidney disease can only be vegetarian? Some nephrologists spontaneously eat vegetarian food after being diagnosed with kidney disease, and do not eat meat, eggs, milk. As a result, the kidney disease was not well controlled. Instead, symptoms of malnutrition such as anemia, fatigue, lack of energy, and poor sleep quality soon appeared.

In fact, animal protein is rich in essential nutrients such as inorganic salt, iron, vitamin B12, vitamin B1, etc. It is also necessary to supplement 1 to 2 taels of lean meat a day for poor kidney function. If you really don’t like eating animal protein, Soybean products should be supplemented daily.

Misunderstanding 2: Can't eat soy products for kidney disease? Everyone knows that protein includes animal protein and plant protein. Although soybeans are plant proteins, their protein content is very high. Each 100 grams of soybeans contains 36.3 grams of protein, which is more than the same weight of lean pork and beef (16.7 grams of protein, respectively). And 20.2 grams). Therefore, it is called high-quality protein together with animal protein.

For kidney friends with proteinuria, it is recommended to use high-quality protein as the mainstay, so soy products can be consumed. But it should be noted that there are many types of soy products, soy beans, black beans, green beans and their soy products are high-quality protein. Mung beans, red beans, peas, broad beans, and kidney beans are starchy beans, and their nutritional value is equivalent to ordinary food. Kidney friends must pay attention when choosing.

Misunderstanding 3: The more protein in urine, the more protein should be supplemented? Many nephrologists think that if there is too much protein loss in the urine, they should eat more and make up more. However, with the increase of protein intake, the amount of urine protein leakage also increases, the kidneys are in a state of high filtration, the burden on the kidneys increases, and renal function declines faster. That is to say, the more protein you eat, the faster the leakage and the more kidney damage. serious.

At present, patients with kidney disease recommend a low-protein diet, that is, limiting protein intake while ensuring sufficient calories (30-35kcal/kg·d). At the same time, with the gradual decline of kidney function, the requirements for protein intake have become more stringent. It is advisable to reduce protein intake at the beginning of stage 1 and stage 2 of chronic kidney disease. Generally, 0.8 g/kg/day is recommended for chronic kidney disease; 0.6 g/kg/day is recommended for chronic kidney disease stage 3 and supplemented with compound alpha keto acid tablets; For kidney disease stages 4-5, the patient should restrict protein more strictly. The recommended protein is 0.4 g/kg/day and supplemented with compound alpha keto acid tablets. In the protein diet, about 50% of the protein should be high biovalent protein.
