In China, there are already 120 million people with chronic kidney disease. Kidney disease patients must pay attention to these seven small details. Although they may seem insignificant, they are crucial in the treatment process and should not allow them to prolong the healing process.
1. High-salt beverages
Edema and blood volume have a significant relationship with sodium salt in chronic nephritis. Therefore, it is necessary to restrict salt intake and provide a low-salt diet. The daily intake of salt should be controlled below 2-4 grams to prevent worsening of edema and increase in blood volume, leading to unexpected complications.
2. High-fat foods
Patients with nephritis often have symptoms of hypertension and anemia. If there is a large amount of animal fat present, it will have a detrimental effect on hypertension and anemia. This is mainly because animal fat can aggravate arteriosclerosis and inhibit hematopoietic function. Therefore, patients with nephritis should be cautious in their consumption.
However, without fat intake, the body will become weaker. Therefore, in daily life, vegetable oil can be used as a substitute, with a daily intake of about 60 grams.
3. Foods high in purines and nitrogen
To reduce the burden on the kidneys, foods that stimulate kidney cells should be restricted, such as spinach, celery, radish, beans, bean products, sardines, chicken soup, fish soup, and meat soup. These foods are high in purines and nitrogen, which can have a negative impact on kidney function when there is renal insufficiency as their metabolic by-products cannot be excreted in a timely manner.
4. Strong seasonings
Strong seasonings are detrimental to kidney function and should be avoided. Monosodium glutamate (MSG) can cause thirst, so it should be used sparingly when water intake is restricted.
5. Foods with high potassium content
Patients with nephritis accompanied by high creatinine levels should never eat foods that contain potassium ions, such as mushrooms, amaranth, cauliflower, spinach, hollowhearted vegetables, bamboo shoots, tomatoes, carrots, melons, mustard greens, passion fruit, loquat, peaches, tangerines, hard persimmons, oranges, and jackfruit. These foods are high in potassium ions. Also, avoid eating raw vegetables.
Other foods with high potassium content include coffee, strong tea, chicken essence, beef essence, ginseng essence, concentrated meat soup, low-salt soy sauce, salt-free soy sauce, half salt, and salt substitutes. When cooking, blanch the food in boiling water, remove the soup, and then stir-fry with oil to reduce potassium intake.
6. Plant protein
The protein intake should be adjusted according to the condition of kidney function. When patients develop oliguria, edema, hypertension, and nitrogen retention, reducing the burden on the kidneys and avoiding the accumulation of non-protein nitrogen in the body is important. Especially in plant protein, there is a large amount of lysine, which can further burden the kidneys' intermediary metabolism. Therefore, beans and bean products should not be used as nutritional supplements.
7. Limit fluid intake
For patients with nephritis and hypertension or edema, fluid intake should be limited. The daily intake should be controlled between 1200-1500 milliliters, including 800 milliliters from beverages and dishes. If edema is severe, the water intake should be strictly controlled. If there is normal urine output, the restriction can be relaxed.
