Potassium is an essential mineral necessary for proper nerve function. For some individuals, too much potassium can cause problems. The potassium in your blood can rise to dangerous levels if you take certain medications or if your kidneys aren't working well. In this case, your physician will likely recommend a low-potassium diet. Potassium is found primarily in fruits and vegetables as well as dairy, grains, legumes, nuts and seeds. When it comes to fruit, you have low-potassium options to choose from.
Safe but Sweet
Low-potassium fruits contain under 200 milligrams of potassium per serving. Apples, cherries, grapes, peaches, pears, pineapple, rhubarb, plums, tangerines and watermelons fall into this category. The serving size for most of these fruits is 1/2 cup. A single peach, plum, apple or tangerine represents one serving. A general guideline is to choose up two to three servings of low-potassium fruits each day, according to Reliant Medical Group.
