A good diet menu to maintain low potassium levels consists of different fruits, vegetables, proteins, grains, and dairy products that have a low potassium content of less than 200 milligrams, states Healthline. The total daily diet should contain about 1,500 to 2,000 milligrams of potassium.
Almost all foods contain potassium, but differ in the potassium content, explains Healthline. Some low-potassium fruits are apples, apricot nectar, blackberries, blueberries and cranberries. Grapes, papaya nectar, canned peaches, peach nectar ad canned pears are additional options, as are pineapples, plums, strawberries, raspberries and watermelon. Low-potassium vegetables include alfalfa sprouts, canned bamboo shoots, bean sprouts, canned beets and cabbage. Other vegetables that fit the criteria are carrots, cauliflower, corn, cucumber and endive. Others with low potassium levels are eggplant, green beans, all types of lettuce, mushrooms, onions and radishes.
In addition to consuming foods with low potassium, it helps to avoid high-potassium foods such as potatoes, bananas, whole grains, milk and tomato products. The National Kidney Foundation recommends consuming only 1 cup or about 8 ounces of coffee per day, reports Healthline.com. Low-potassium cookbooks and free recipes are readily available online, including the National Kidney Foundation’s "My Food Coach and Kidney Cooking" family recipe book.
