About this food

In a CKD diet, Fruits deserve attention: Rhubarb - 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.

Nutrient insight

Potassium is the highest of the three at 14%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
