For the average person, consuming foods high in potassium provides a wealth of benefits, from relief of cramps to improved electrolyte balance. However, people with chronic kidney disease can experience unpleasant symptoms such as numbness and tingling, difficulty breathing, palpitations, and irregular heartbeat if they consume too much of the nutrient. In such cases, doctors often recommend a eat low-potassium diet.
Potassium is measured in milligrams. A normal, healthy person should consume 3500 to 4500mg of potassium per day through their diet. For those on a restricted diet, experts recommend 2000mg or less per day. Foods with more than 200mg per portion are considered high in potassium; patients with renal failure or other kidney problems must consume foods much lower in the mineral.
