Eating for Kidney Disease
A kidney-friendly diet helps protect the kidneys and manage symptoms in chronic kidney disease. It usually means adjusting salt, protein, potassium and phosphate to individual needs.
Causes & risk factors
- Supports management of chronic kidney disease
- Helps control blood pressure and fluid
- Reduces the buildup of waste products the kidneys struggle to clear
Common symptoms
- Not a disease — a management plan
- Helps reduce fluid swelling
- Can ease tiredness from waste buildup
Tests & diagnosis
- Creatinine
- Kidney function (RFT)
- Potassium
- Electrolytes
- Urine protein
Treatment & management
- Reduce salt to help control blood pressure and fluid
- Adjust protein to the amount your team advises
- Limit high-potassium foods if potassium is high
- Watch phosphate (dairy, processed foods) as advised
- Personalise the plan with a renal dietitian — do not self-restrict blindly
When to see a doctor urgently
- A new diagnosis of kidney disease needing diet advice
- High potassium or phosphate on blood tests
- Swelling or blood pressure that is hard to control
- Before making big diet changes, check with your kidney team
Frequently asked questions
Should everyone with kidney disease cut protein?
Not the same way — protein needs vary with the stage and whether you are on dialysis. A renal dietitian sets the right amount; cutting too much can cause malnutrition.
Which foods are high in potassium?
Bananas, potatoes, tomatoes, coconut water and many fruits are high in potassium. If your level is high, your dietitian will guide which to limit and how to prepare them.
