Before dialysis is needed, there's no special "kidney diet" that will slow the disease — but eating a healthy, balanced diet can help support your overall health and energy levels.
What Does a Healthy, Balanced Diet Look Like?
Here are some simple guidelines to follow:
🍎 Eat Plenty of Fruit and Vegetables
Try to include some fresh fruit, vegetables, or salad with every meal. They’re rich in vitamins, minerals, and fibre.
🥛 Include Dairy or Dairy Alternatives
Choose low-fat milk, yogurt, or plant-based alternatives like soya milk — they’re good sources of calcium and protein.
🍞 Choose Wholegrains When You Can
Opt for wholemeal or wholegrain bread, pasta, and rice. These provide more fibre and nutrients than white varieties.
🍗 Add Protein to Every Meal
Include a source of protein such as beans, lentils, eggs, fish, or lean meat to help maintain muscle and strength.
🧈 Use Healthy Fats in Small Amounts
Choose unsaturated fats like olive oil or vegetable-based spreads. Keep portion sizes small.
🥩 Cut Back on Red and Processed Meats
Try to limit red meat (like beef and lamb) and avoid processed meats like ham, bacon, and sausages — they’re high in salt and saturated fat.
💧 Stay Well Hydrated
Drink plenty of fluids unless advised otherwise by your healthcare team.

🧂 Diet and Fluids at Advanced Kidney Disease
As kidney function declines, it's essential to be even more mindful of your diet and fluid intake. At this stage, the kidneys are less able to remove waste products and excess minerals from your body — which means substances like potassium and phosphate can build up and make you feel unwell.
⚠️ Why This Matters
When the kidneys aren't working properly, excess levels of certain nutrients can lead to:
-
Tiredness or weakness
-
Nausea or poor appetite
-
Heart rhythm problems (from high potassium)
-
Bone and joint issues (from high phosphate)
👩⚕️ Will I Need a Special Diet?
Not everyone with kidney disease needs a restricted diet — but if you do, your nursing team or a renal dietitian will guide you. You may be asked to follow a:
-
Low potassium diet
-
Low phosphate diet
-
Fluid restriction plan
-
Or other specific dietary adjustments
These plans are personalised to your needs — please don’t make dietary changes unless advised by your healthcare team.
