What naturally repairs kidneys?
Foods for Healthy Kidneys A balanced diet low in sodium, phosphorus, and potassium, while high in quality protein, is essential for healthy kidneys. For example, red bell peppers are low in potassium (and high in flavor), which make them a great snack. Foods that cause kidney stones include products high in oxalates: spinach, rhubarb, almonds, cashews, miso soup, cereals, baked potatoes (with the skin), beets, cocoa powder, okra, bran, French fries, raspberries, stevia, and sweet potatoes.
