Kidney Disease Diet: What to Eat and Avoid

Diet plays a critical role in managing chronic kidney disease and slowing its progression. The kidneys regulate fluid, electrolytes, and waste; dietary modification helps compensate when they fail.

Key restrictions include reducing sodium, limiting potassium (in advanced CKD), controlling phosphorus, and moderating protein intake. Needs are highly individualized.

Working with a renal dietitian is essential, as restrictions change with disease progression. Many healthy foods may need to be limited in advanced CKD due to high potassium or phosphorus content.

Adequate caloric intake and protein (without excess) are critical to prevent malnutrition. Plant-based proteins may offer advantages over animal proteins in CKD.
