That headline is partly true but oversimplified. If you have high creatinine, the best diet depends on why your creatinine is elevated and what stage of kidney disease (if any) you have. There is no universal list of “3 good fruits” and “3 bad fruits.”
Here are some general points:
Fruits that may fit well into a kidney-friendly diet (for many people)
- Blueberry – Low in potassium and rich in antioxidants.
- Apple – A good source of fiber and relatively low in potassium.
- Strawberry – Contains vitamin C and antioxidants with moderate potassium.
Fruits that some people with advanced kidney disease may need to limit
These are not unhealthy fruits, but they are relatively high in potassium:
- Banana
- Orange (and orange juice)
- Avocado
Whether you need to limit high-potassium foods depends on your blood potassium level and your healthcare provider’s advice. Many people with mild kidney disease do not need to avoid these fruits.
A few important facts
- Creatinine is a marker of kidney function, not a disease itself.
- High creatinine can result from dehydration, certain medications, muscle mass, strenuous exercise, or kidney disease.
- Simply eating certain fruits is unlikely to lower creatinine if there is an underlying kidney problem.
If you’ve been told your creatinine is high, the most helpful next step is to know your:
- Creatinine level.
- Estimated glomerular filtration rate (eGFR).
- Potassium level.
Those results are much more useful for choosing the right diet than a generic list from a social media post.
