Who needs to limit potassium?
People with kidney disease can have too much potassium in their blood. Their care team may then advise them to limit high-potassium foods, says the National Kidney Foundation. Potassium can also run too low, so the right amount is set per person. Follow the amounts your own care team gives you.
What counts as low in potassium?
The National Kidney Foundation counts a food with less than 200 mg of potassium per serving as low, and one with 200 mg or more as high. Serving size matters: a large amount of a low-potassium food can turn it into a high-potassium one.
Soaking and boiling some vegetables (leaching) lowers their potassium. It removes some of it, not all.
