Eggs are a high-quality, kidney-friendly protein — low in potassium and sodium, moderate in phosphorus. The egg yolk is higher in phosphorus than the white; most renal dietitians allow both in moderation.
One large egg: ~6 g protein, ~63 mg sodium, ~65 mg potassium, ~95 mg phosphorus. Compared to other proteins, eggs are one of the friendlier choices for CKD.
Phosphorus in eggs is less absorbable than additive phosphorus in processed foods — the whole-egg phosphorus load is acceptable within a normal renal diet.
Egg whites alone are sometimes recommended in advanced CKD when phosphorus is high — they give pure protein without yolk phosphorus.
Preparation matters: skip frying with salt; boiled or poached is best for kidney patients.
