Is spinach harmful for kidney failure?
First of all, I’d like to say spinach is indeed a good nutritious foods, but it is not necessary for everyone. For kidney failure patients, it’s better for them to ask their nephrologist whether they can enjoy this food due to the disturbance of calcium metabolism.
Normally, our serum potassium level remain between 3.5 and 5.0mEq/L. Keeping calcium level in the normal range is essential, as calcium plays a crucial role in our bone and many other body parts. However, for kidney failure patients, due to impaired kidney function, they run a high risk for low calcium level in blood. For this reason, it is necessary for them to avoid foods that may cause decrease of their serum calcium level.
For raw spinach, it is high in oxalate which has a tendency to bind to the mineral calcium. Therefore, if not enough calcium is eaten with spinach, it will take calcium from bones, thus causing osteoporosis. Besides, oxalate joints with excess calcium in the kidney, which can cause kidney stone. For these reasons, kidney failure patients are usually not suggested to eat spinach.
