Egg whites are the ideal dialysis protein — nearly zero phosphorus and low potassium. Whole eggs add the yolk's phosphorus and cholesterol, so dialysis patients typically use whites as the protein workhorse and limit yolks.
Dialysis raises protein needs to 1.2 g/kg/day while phosphorus must stay controlled — a tension that makes egg whites (15 mg phosphorus/100g) the single best protein source in renal diets.
The yolk carries most of the egg's phosphorus (~120 mg per yolk) and the cholesterol. One whole egg is fine for most dialysis patients, but making whites the staple protects the phosphorus budget.
Bottom line: eat egg whites freely as a protein anchor; treat whole eggs as a counted, limited item on dialysis.
