7. Celery Root
Celery root contains both potassium and sodium. It gives the kidneys everything they need to perform their job. Celery root is also high in water, which increases the amount of urine produced by your body. This helps to eliminate residual toxins. Celery root may prevent infections in the urinary and kidney tracts. Celery root has been shown to shrink cysts in the reproductive organs.
Celery contains a low level of potassium. Even a large stalk only contains 4% of the basic RDI. Speak to your doctor if you already have kidney disease about adding celery into your diet.
