If you were to google “foods to avoid with kidney disease,” bananas would likely be one of the most common foods you’d find on that list. Why do so many sources say those with Chronic Kidney Disease need to avoid bananas, and can you actually enjoy them when you have CKD? Let’s find out!
Bananas with Chronic Kidney Disease
Bananas are high in potassium, magnesium, and fiber. These nutrients are vital for the general healthy population. However, if you have CKD, sometimes you can eat too much potassium for your kidneys to handle.
This can result in hyperkalemia or high potassium levels in your blood. If you are experiencing hyperkalemia, you may be advised to limit the amount of potassium you are consuming in your diet.

Research on Bananas and Chronic Kidney Disease
There is limited research on bananas and chronic kidney disease; however, we know they can be enjoyed safely on a kidney-friendly diet. So many outdated sources and handouts may tell you to avoid bananas with CKD because they are high in potassium.
However, it’s important to remember that many other foods, not just bananas, contain potassium. Just like other high-potassium foods, if you need to limit potassium in your diet, you might want to be mindful of the portion size of your bananas or how frequently you are eating them. For example, you could try eating half a banana in your favorite dishes instead of eating one large banana daily.
Does Boiling Bananas Make it Easier for Chronic Kidney Disease?
According to a research study in Uganda, boiling bananas can effectively remove some of the potassium content. However, bananas are often enjoyed alone or in a baked good. Therefore, boiling your bananas may not be as palatable for you. Bananas go great in oatmeal, baked goods, smoothies, or just by themselves.

The Bottom Line of Bananas with Chronic Kidney Disease
Overall, bananas can be enjoyed with CKD. They are high in potassium, so if you need to limit potassium in your diet, it may be a good idea to be mindful of your portion size. Instead of one large banana daily, try having a small or half of a large banana.
Remember, everyone has different potassium needs, and it’s important to speak with your doctor and healthcare team to ensure that you are eating the right amount of potassium for your body.
