About this food

How to think about Fruits: Grapes is worth a closer look - 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.

Grapes's potassium is the top contributor (10% of its limit), so its potassium density deserves attention. In CKD stage 3-4 the kidneys clear potassium less well - control portions, and peeling, slicing or boiling can help.
