Potassium is an essential nutrient used to maintain fluid and electrolyte balance in the body.
A deficiency in potassium causes fatigue, irritability, and hypertension (increased blood pressure).
Overdose of potassium from natural sources is nearly impossible, however, it is possible to consume too much potassium via potassium salts which can lead to nausea, vomiting, and even cardiac arrest.
For those with chronic kidney disease (CKD) who need to lower their potassium, this list can serve as a guide on what vegetables to eat or avoid depending on your own restrictions. Most people with CKD should not consume more than 200mg of potassium per serving, or 2000mg per day. This article can only be used as a guide, but the amount of potassium you eat each day should be set by your care provider. See also our list of low potassium vegetables for more ideas.
Vegetables high in potassium include beet greens, lima beans, swiss chard, potatoes, acorn squash, spinach, boy choy, mushrooms, tomatoes, and, sweet potatoes. The current daily value (%DV) for potassium is 4700mg, recently increased from 3,500mg by the FDA.
