While bananas might be the first fruit to come to mind, watermelon actually reigns supreme when it comes to potassium. In just 2 wedges, or about 1/8th of a melon, you'll get 640 mg of potassium, or about 14% DV. Watermelon is also a great source of vitamin C, vitamin A, and the antioxidant lycopene.
Although bananas are a good source of potassium, many other nutritious foods, including sweet potatoes, legumes, and beets, offer more potassium per serving. Swiss chard, yams, and white beans even have twice as much potassium per cup as a medium banana.
Adults should consume about 3,500mg of potassium per day, according to the UK's National Health Service. The average banana, weighing 125g, contains 450mg of potassium, meaning a healthy person can consume at least seven-and-half bananas before reaching the recommended level.
Juice from potassium-rich fruit is also a good choice: Orange juice. Tomato juice. Prune juice.
A healthy adult should aim to consume 3,500–4,700 mg daily from foods. To increase your intake, incorporate a few potassium-rich foods into your diet such as spinach, yams, avocados, bananas, and fish, such as salmon.
One large egg contains about 63 mg of potassium. 1 Eggs are considered a low-potassium food, but check with your doctor or dietitian to find out how often you should eat them.
Some of the best sources of potassium are dark leafy greens such as spinach, which when cooked has an astounding 1,180 mg per cup, per USDA data. Swiss chard is a close second, with almost 1,000 mg per cooked cup, and even bok choy has around 445 mg per cup when cooked.
A fast-food cheeseburger contains between 225 and 400 mg of potassium. And one small order of fries? A whopping 470 mg of potassium in just 3 oz. Just 1 oz of salted potato chips contain 465 mg.
Low-potassium fruits:
Apples (plus apple juice and applesauce) Blackberries. Blueberries. Cranberries.
A ½ cup serving of blueberries has less than 150 milligrams potassium making them a low potassium fruit choice. Blueberries are also low in sodium and phosphorus making them suitable for a kidney friendly diet. They are safe to eat for all of the following kidney conditions and treatments: CKD/Transplant.
Vomiting, diarrhea or both also can result in excessive potassium loss from the digestive tract. Occasionally, low potassium is caused by not getting enough potassium in your diet. In most cases, low potassium is found by a blood test that is done because of an illness, or because you are taking diuretics.
Usually, 60–80 mmol of supplements per day for a few days to weeks is sufficient for treating mild to moderate hypokalemia. That said, always follow the recommendations of your healthcare professional ( 1 , 19 ). In severe hypokalemia cases, intravenous (IV) treatment may be recommended.
Most meats add some potassium to your meals. Chicken breast has the most per 3-ounce serving with 332 milligrams, but beef and turkey breast contain 315 and 212 milligrams, respectively.
Whole grains, including oats, are considered good potassium sources. One serving of instant or steel-cut oatmeal provides about 130 milligrams of potassium. If you're aiming to increase your potassium intake, you can bring this amount up significantly by adding high-potassium fruit to your oatmeal.
There are limited or no options for at-home kits to test potassium levels. If you are prescribed a 24-hour urine test, you will need to collect your urine wherever you are during the day, including at home. However, this testing is still prescribed by your doctor rather than sold as a separate at-home test kit.
If you're looking to jumpstart your day with potassium, a cup of plain, regular yogurt can provide up to 573mg, or 12% DV, of potassium. Don't get Greek yogurt, though! It isn't the same thing, and doesn't have the same potassium and calcium as regular yogurt.
A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop. The diagnosis is based on blood tests to measure the potassium level. Usually, eating foods rich in potassium or taking potassium supplements by mouth is all that is needed.
You can reduce your risk of developing hypokalemia by eating a diet full of foods that contain potassium. Discuss your diet with your healthcare provider. Foods that contain potassium include many fruits and vegetables, lean meat and fish, dairy and legumes.
Chocolate and nuts contain high amounts of phosphorus and potassium.
What is the best form of potassium to take? A person should prioritize getting potassium from their diet. Sources of potassium include dried apricots, lentils, squash, prunes, potato, kidney beans, and bananas. Apricots offer the most potassium.
