For those diagnosed with chronic kidney disease (CKD) the shock of being diagnosed with the disease is often accompanied with dietary guidelines restricting intake of potassium and other electrolytes. The next realization is that almost all vegetables contain some amount of potassium.
While this is true, there are a few vegetables out there which are low in potassium, and the amount of potassium in vegetables can be further reduced by soaking the vegetables in water before cooking in a process called leaching. This works well for vegetables which will be eaten raw. Cooked vegetables should be boiled, and the water they are boiled in should be discarded.
For this list, a low potassium vegetable can be considered to have less than 200mg of potassium per serving (please watch portion sizes).
