Kidney Disease (CKD) Diet Guide

No — protein, potassium, and phosphorus targets all change as kidney function changes. A diet appropriate for early-stage CKD can be wrong for later stages, which is why this needs to be matched to your specific eGFR and labs, not a generic chart.

Yes, appropriately individualized nutrition is one of the most effective non-medication tools for slowing progression, alongside your nephrologist's medical management.

As kidney function declines, the kidneys become less able to clear excess potassium from the blood, and high potassium levels can become dangerous for heart rhythm — this is why potassium tracking matters more as CKD progresses.

No — protein needs to be carefully balanced, not just restricted; too little causes malnutrition, too much accelerates strain on the kidneys. This should always be set based on your specific labs and stage, ideally with a dietitian and your nephrologist together.
