Nutritional Management

When you suffer from chronic kidney disease (CKD), nutritional management is an essential part of your treatment plan. Depending on the severity of your disease, your recommended diet may change over time. In predialysis, a low protein diet is a key pillar of a CKD therapy. Read more about the recommended food intake when suffering from CKD.

Diet in chronic kidney disease (CKD)

The recommended renal diet depends on numerous factors such as the patient´s body size, weight, age, stage of CKD, activity level and other health conditions. The goal of the CKD diet is to preserve existing kidney function and to delay the progression of CKD, ultimately delaying dialysis or gaining time while waiting for a transplant.

If you are suffering from CKD, several nutrients (foods good for kidneys) should be carefully monitored.

While choosing or preparing food, you should have the following nutritional rules in mind:

  • Low amounts of sodium (especially table salt)
  • Low amounts of phosphate (e.g. seafood, cereals, chocolate, bean products etc.)
  • Sufficient calories (energy to avoid malnutrition)
  • Protein:
    • Low amounts of protein (in predialysis stages)
    • High amounts of protein in dialysis stage

Low protein diet in predialysis

Nutritional management, including adjustment of protein, as well as a regular medication prescribed by your doctor can lead to improved symptom control and slow down the progression of CKD.

Although proteins are important for various functions of your body, over-consumption of protein will lead to a waste build-up, especially when your kidneys are weak. A protein-restricted diet will help you to reduce waste products from protein in your body and provide you several benefits (see figure below).

Benefits of protein-restricted diet

Benefits of protein-restricted diet

  • KIDNEY FUNCTION
    • decreased workload of kidneys and thereby preserved renal status
  • METABOLIC COMPLICATIONS
    • reduced risk of metabolic complications of CKD
  • DIALYSIS START
    • delayed onset of dialysis

Eating less protein helps to preserve kidney function and prevent additional stress on the kidneys. Your dietitian or doctor will tell you how much protein you should consume daily.

Treatment options

Treatment of chronic kidney disease (CKD) varies according to the severity. However, steps can be taken in all cases to: control hypertension, correct salt and water imbalance, treat urinary tract infections, and reduce risk of heart and blood vessel diseases. Most people with CKD will be able to slow down progression through regular check-ups and medication intake.
