In the diet for renal failure, it is necessary to control the intake of nutrients such as salt, phosphorus, potassium and proteins, and in the most severe cases, it is also necessary to control the consumption of fluids in general, such as water, juices and soups.
For example, these patients should avoid eating meat, fish, nuts, beans and certain types of fruits and vegetables, such as orange, kiwi, tomato and potato; however, there are also strategies to reduce the potassium content of fruits and vegetables, such as peeling vegetables and changing cooking water at the time of preparation.
- It is important to remember that the amount and food allowed or prohibited varies depending on the stage of the disease and the patient’s scans.
- So the diet for renal failure is specific to each person.
- And should be personally guided by a nutritionist.
In general, foods that people with kidney failure should consume sparingly include:
The kidney of patients with renal impairment has difficulty removing excess potassium from the blood, so these people need to control their intake of this nutrient. Potassium-rich foods include:
Excess potassium can cause muscle weakness, arrhythmias and cardiac arrest, so the diet in case of chronic kidney failure should be individualized and monitored by the doctor and nutritionist, who will value the appropriate amounts of nutrients for each patient.
People with chronic kidney failure should also avoid foods rich in phosphorus to control kidney function.
Symptoms of excess phosphorus include itching in the body, high blood pressure and mental confusion, and patients with kidney failure should be aware of these signs.
Patients with chronic renal impairment need to control their protein intake, as the kidney also cannot eliminate excess of this nutrient, for example, these people should avoid excessive consumption of meat, fish, eggs, milk and dairy products, as they are high in protein. Food.
Ideally, the patient with renal impairment should eat only about 1 small beef fillet for lunch and dinner and 1 glass of milk or yogurt a day, however, this amount varies depending on kidney function, being more restrictive for people in which the kidney is no longer functioning.
People with kidney failure should also monitor their salt intake, as excess salt increases blood pressure and forces the kidney to function, further impairing the function of this organ. The same goes for excess fluid, as these patients produce little urine and excess fluid builds up. causes problems such as swelling and dizziness.
Therefore, these people should avoid using
To avoid excess salt, a good option is to use herbs to season foods such as parsley, coriander, garlic and basil, the doctor or nutritionist will indicate the appropriate amount of salt and water allowed for each patient. See more tips on: How to reduce salt intake.
In addition to avoiding consumption of potassium-rich foods, there are also strategies that help reduce the potassium content of fruits and vegetables, such as:
Another important tip is to avoid the use of pressure cookers and microwaves when preparing meals, as these techniques concentrate the potassium content in food as they do not change the water.
Restrictions on the kidney patient’s diet can make it difficult to choose snacks, so the 3 most important guidelines for choosing healthy snacks for kidney disease are:

The diet for acute kidney failure is usually carried out in a hospital setting, the nutrients ingested by the patient are carefully calculated and food is often used through serums containing nutrients placed in the bloodstream.
Once renal function is restored, the patient receives specific instructions on what to eat, to prevent the accumulation of toxins that are normally eliminated by the kidneys. Usually, the developed diet is low in protein, potassium, salt and phosphorus, too. patients with chronic renal impairment.
