Can kidney patients eat potatoes?

Potatoes are high in potassium (421 mg/100g; ~728 mg per medium potato). Advanced CKD/dialysis: avoid or strictly limit. If eaten, use the leaching method: peel, cut into small cubes, soak in water for 2 hours, then boil in excess water and discard the water — this removes up to half the potassium.

Are sweet potatoes better for kidneys?

Sweet potatoes are also high in potassium (~337 mg/100g) and should be similarly limited. Neither variety is 'safe' for potassium-restricted patients without leaching. For renal diets, rice, lauki, and cauliflower are safer carbohydrate choices.

Potatoes are very high in potassium (421 mg/100g) — a medium potato has ~728 mg. For CKD stages 3-5 and dialysis, potatoes should be limited or leached (peel, slice, boil in excess water, discard water — removes ~50% potassium). Potato chips are worse: concentrated potassium + sodium + fat.
