After developing the disease, both patients with chronic renal failure and their families mistakenly believe that so-called "renal failure" means the kidneys are relatively weak and that the body needs to be nourished. Consequently, they allow patients to consume large amounts of nutritional supplements. This is a common misconception among patients with renal failure. This concept and practice are very wrong.
Protein is the primary building material for human cells and tissues and is extremely important for the body. When consuming protein-rich foods, it is first broken down by the liver and then excreted by the kidneys. Therefore, when kidney function declines, it is necessary to appropriately reduce protein intake to avoid加重 the burden on the kidneys. Some nutritional supplements, as well as foods like snake meat and dog meat, are all high-protein foods. After consuming so much high-protein food, patients with renal failure may be unable to handle the load, and toxins in the body cannot be excreted in a timely manner through urine, which can lead to a worsening of the condition. In the treatment of chronic renal failure, dietary control should be the top priority.
Professor Liu Guanxian reminds patients with chronic renal failure that excessive protein intake will worsen the condition, but too little intake can lead to malnutrition. The principle for protein intake is to meet the body's metabolic and nutritional needs without increasing the burden on the kidneys. Therefore, high-quality protein should be consumed—protein rich in essential amino acids for the body, such as chicken, lean pork, eggs, fish, and milk. The protein intake for patients with renal failure should generally be around 20 grams per day. Moderate alcohol consumption may prevent renal failure in men
So, for patients with chronic renal failure, how should they manage this amount in their daily diet? Professor Liu Guanxian gave an example: he said that eating one egg and 200 milliliters of milk every day is equivalent to consuming 12-15 grams of protein, and with the protein from other foods, it should be almost enough. At the same time, plant protein intake should be reduced, because plant protein contains many non-essential amino acids. Starch, water chestnut starch, sweet potatoes, honey, and sugar should be used as substitutes for part of the staple foods, such as rice and flour, as much as possible.
Professor Liu Guanxian said that according to statistics from the International Society of Nephrology, the annual incidence rate of chronic kidney disease is 2‰-3‰, and the annual incidence rate of chronic renal failure is 100/1,000,000-150/1,000,000. The number of patients is also increasing year by year. Chronic renal failure is slowly developed from kidney diseases, so the prevention of chronic renal failure is extremely important. In the treatment of patients with chronic renal failure, dietary control is the top priority. In the early stages of renal failure, diet combined with traditional Chinese medicine therapy can control the condition. Patients with renal failure must pay close attention to their diet.
In addition to protein, the intake of salt and water is also a problem that patients with renal failure must pay attention to. It is understood that in 2006, more than 80 patients with uremia who underwent hemodialysis at the Municipal People's Hospital, an increase of 47 from the previous year. The number of cases undergoing hemodialysis at the Municipal People's Hospital also increased compared to previous years.
Huang Yuhua, an associate chief physician in the Department of Internal Medicine at the Municipal People's Hospital, explained that the metabolic waste produced by the human body is mainly excreted by the kidneys. Due to the progressive and irreversible development of renal damage in patients with chronic renal failure, it inevitably leads to the retention of metabolic waste. At the same time, the retained waste in turn affects various organs in the body, forming a vicious cycle that worsens the condition. A reasonable diet for patients with chronic renal failure helps to reduce the retention of metabolic waste and delay the progression and deterioration of chronic renal failure. Patients with chronic renal failure who have symptoms of hypertension, edema, and oliguria must limit their salt and water intake to avoid excessive water and sodium retention, which can worsen edema and hypertension. However, not all patients with renal failure need to control their water and salt intake; this should be determined by a doctor based on the specific situation.
