Kiwi and your kidneys
Potassium, phosphorus, protein and salt in kiwi, per 100 grams and per portion, and what it means when you have kidney disease. The figures come from the Norwegian food composition table.
Is kiwi good for your kidneys?
Yes, kiwi is healthy, but fairly high in potassium: one kiwi gives around 220 mg. With normal potassium it is perfectly fine. If you need to limit potassium, ask your dietitian how much fruit fits into your plan.

How much potassium is in kiwi?
Kiwi: 295 mg of potassium per 100 grams, which is medium by Metodebok's grouping: under 150 mg per 100 grams is low, 150 to 300 mg medium, and over 300 mg high. What you eat is the portion, so see the numbers per portion above.
With less potassium
If you need to limit potassium, these foods in the same group are low in potassium, per 100 grams.
- Apple: 63 mg
- Watermelon: 100 mg
- Blueberries: 122 mg
- Pineapple: 123 mg
- Mango: 149 mg
How much phosphorus is in kiwi?
Kiwi: 33 mg of phosphorus per 100 grams. Phosphorus from plants is absorbed less than phosphorus from meat, milk and additives. Phosphate added to processed food (E338 to E341, E450 to E452) is absorbed almost completely and is not in the table, so check the ingredient list.
What does this mean for you?
How much potassium, phosphorus and protein you should eat depends on your blood tests, your stage and whether you are on dialysis. Many people with kidney disease do not need to limit potassium at all. Do not cut out fruit and vegetables unless your doctor or a clinical dietitian has asked you to.
Salt applies to everyone with kidney disease: under 5 grams a day helps blood pressure and the kidneys.
