About this food
About Bananas: Potassium levels vary widely across fruits - apples and berries are low-potassium, kidney-friendly picks, while bananas and avocados are high and need portion control. The natural sugar in fruit is usually not the issue; potassium is. As a Fruits item, its role in a kidney diet depends mainly on mineral content.
Nutrient insight
Potassium at 18% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.
