What foods should not be eaten by nephritis and what foods should be paid attention to

The function of the kidneys is to excrete metabolic products, regulate the balance of water, electrolytes and acid-base, secrete a variety of active substances, maintain the stability of the body's internal environment, and ensure the body's normal physiological functions. So what foods should not be eaten by people with nephritis?

1. High-salt diet: The edema of chronic nephritis is closely related to blood volume and sodium salt, so salt intake must be restricted and a low-salt diet should be given. Daily salt intake should be controlled below 2-4 grams to prevent worsening of edema and increase in blood volume, which may lead to accidents.

2. High-fat food. Patients with nephritis generally have symptoms of hypertension and anemia. If there is a large amount of animal fat, it will have a great negative impact on hypertension and anemia. This is mainly because animal fat can aggravate arteriosclerosis and inhibit hematopoietic function. Therefore, patients with nephritis must consume it with caution.

3. Foods high in purine and nitrogen: In order to reduce the burden on the kidneys, you should limit foods that stimulate kidney cells, such as spinach, celery, radishes, beans, soy products, sardines, chicken soup, fish soup, broth, etc. Because those foods are high in purine and nitrogen, when renal function is poor, their metabolites cannot be excreted in time, which has a negative impact on renal function.

4. Strong condiments

Strong seasonings are harmful to kidney function and should be avoided. Since MSG will make you thirsty after eating too much, you should also use less MSG when limiting your water intake.

5. Foods with high potassium ion content. Patients with nephritis and high creatinine must not eat foods containing potassium ions, such as shiitake mushrooms, amaranth, cauliflower, spinach, water spinach, bamboo shoots, tomatoes, carrots, pumpkin, mustard greens, guava, loquat, peaches, oranges, persimmons, oranges, sugar apples, etc. These all contain potassium ions. Also, do not eat raw vegetables.

6. Plant protein: The amount of protein intake should depend on the condition of kidney function. When patients experience oliguria, edema, hypertension and nitrogen retention, it can reduce the burden on the kidneys and avoid the accumulation of non-protein nitrogen in the body. In particular, plant protein contains a large amount of leuprorelin, which can aggravate the kidney's intermediate metabolism. Therefore, it is not appropriate to use beans and bean products as nutritional supplements.

7. Limit the amount of fluid. Patients with nephritis, hypertension and edema should limit their fluid intake. The daily intake should be controlled within 1200-1500 ml, including 800 ml of water in beverages and dishes. If edema is severe, the amount of water intake must be strictly controlled. In the case of urination, it can be relaxed appropriately.

8. Tofu: In daily life, patients with chronic nephritis should strictly limit the intake of tofu in their diet. This is because in order to effectively relieve the pain, patients with chronic nephritis should limit their protein intake to avoid the difficulty in excretion of protein metabolites in the body, such as urea, uric acid, and creatinine, which may lead to accumulation and poisoning. Tofu is a high-protein food, so you should not eat too much.

9. Patients with chronic nephritis need to avoid eating lamb liver in daily life, because it will hinder effective treatment. Normally, after protein is metabolized in the body, some nitrogen-containing wastes, such as urea and creatinine, will be produced, which need to be excreted through the kidneys in the urine. However, this is not good for the kidneys of patients with chronic nephritis, so it is easy to cause serious harm to the patients.

10. Hairtail is widely consumed in daily life, but patients with chronic nephritis should pay attention to reducing their consumption. This is because hairtail contains a large amount of fat and carbohydrates. After being metabolized in the human body, it will produce a large amount of water and carbon dioxide, which will increase the burden on the kidneys. Excessive retention of non-protein nitrogen in the body can cause uremia. Hairtail contains up to 18% protein, so it is not suitable for patients with acute nephritis to eat it.
