Coffee and CKD: Potassium, Phosphorus & Sodium Reference
For a CKD diet at stage 3-4, Coffee comes out as Kidney-friendly. Coffee scores Kidney-friendly across all three minerals - Potassium leads at 3% of its limit, far from any caution threshold.
About Coffee
How to think about Beverages: Coffee is worth a closer look - Most beverages are low in mineral density, but colas with phosphoric acid and sugary drinks are not kidney-friendly - additive phosphorus absorbs at nearly 100%, often alongside a lot of added sugar.
Nutrient insight
Coffee's potassium is the top contributor (3% 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.
