Dozens of fruits are rich in potassium, and many of them deliver more per serving than the banana most people think of first. A medium banana contains about 451 mg of potassium, which is solid but far from the top of the list. Dried fruits, plantains, and several tropical options all surpass it, sometimes by a wide margin.
How Much Potassium You Need
The recommended daily intake is 3,400 mg for adult men and 2,600 mg for adult women. Those numbers stay the same past age 50. During pregnancy the target rises slightly to 2,900 mg, and during breastfeeding it’s 2,800 mg. Most people fall short of these targets, which makes fruit an easy way to close the gap since you can eat it without any preparation.
The Highest-Potassium Fruits
Based on USDA nutrient data, these fruits top the list per standard serving:
- Dehydrated apricots (1 cup): 2,202 mg
- Dehydrated peaches (1 cup, stewed): 1,341 mg
- Plantain, raw (1 whole): 1,315 mg
- Dried currants (1 cup): 1,119 mg
- Breadfruit (1 cup): 1,078 mg
- Dried apricots, stewed (1 cup halves): 1,028 mg
- Passion fruit (1 cup): 821 mg
- Dried pears, stewed (1 cup halves): 658 mg
- Kiwi (1 cup, sliced): 562 mg
- Pomegranate juice (1 cup): 533 mg
A single cup of dehydrated apricots covers nearly two-thirds of a man’s daily potassium needs and almost an entire day’s worth for a woman. Even a cup of sliced kiwi gives you more potassium than a banana.
Why Dried Fruit Ranks So High
You’ll notice dried fruits dominate the top of the list, and there’s a simple reason. Removing water concentrates everything else in the fruit, including potassium. Half a cup of dried apricots contains roughly 750 mg of potassium, while the same amount of fresh apricots has about 200 mg. That’s nearly four times more potassium from the dried version.
The tradeoff is that dried fruit also concentrates sugar and calories. A cup of dried apricots has significantly more calories than a cup of fresh ones. If you’re using dried fruit to boost your potassium intake, smaller portions go a long way. Ten dried apricot halves, a much more realistic snack size, still deliver about 407 mg. Half a cup of dried dates provides 584 mg.
Fresh Fruits Worth Adding to Your Diet
If you prefer fresh fruit, plantains are the standout. One raw plantain packs 1,315 mg of potassium, nearly triple what a banana offers. Plantains are starchier and less sweet than bananas, so they’re typically cooked rather than eaten raw, but the potassium holds up through cooking.
Passion fruit is another strong option at 821 mg per cup. It’s not a fruit most people eat in large quantities, but even half a cup puts you well ahead of a banana. Kiwi is more accessible for everyday eating. A cup of sliced green kiwi delivers 562 mg, and since kiwis are small, that’s roughly three to four fruits.
Breadfruit, common in Caribbean and Pacific Island cuisines, provides 1,078 mg per cup. It’s less widely available in typical grocery stores but worth seeking out if you cook with tropical ingredients.
Pomegranate juice rounds out the top ten at 533 mg per cup. Since it’s a beverage, it’s one of the easiest ways to add potassium without changing your meals.
Bananas in Context
Bananas aren’t a bad source of potassium. At 451 mg per medium fruit, they’re convenient, inexpensive, and widely available. But their reputation as the potassium fruit is somewhat exaggerated. A single plantain delivers about three times more. A cup of dried apricots delivers nearly five times more. Even a cup of kiwi edges bananas out.
The reason bananas get all the credit likely comes down to familiarity. They’re the most consumed fruit in many countries, so they end up being the default recommendation. If you like bananas, keep eating them. But if you’re specifically trying to increase your potassium intake, the fruits listed above will get you there faster.
What Potassium Does in Your Body
Potassium is an electrolyte that works alongside sodium to manage fluid balance in your cells. Sodium pulls fluid into cells, and potassium helps move byproducts out. This back-and-forth keeps your cells properly hydrated and functioning.
Beyond fluid balance, potassium plays a direct role in muscle contraction, nerve signaling, and heart rhythm. Your kidneys use it to filter blood and regulate how much fluid your body retains. When potassium runs low, the most common early signs are muscle cramps, fatigue, and weakness, all consequences of disrupted electrical signaling in muscle and nerve cells.
Fruits are a particularly useful source because they tend to be low in sodium. Since potassium and sodium work in opposition when it comes to blood pressure, getting potassium from a low-sodium food amplifies the benefit. A high-sodium, low-potassium diet pushes your body to retain fluid, which raises blood pressure. Shifting that ratio by eating more potassium-rich fruit helps your kidneys excrete excess sodium and fluid.
Practical Ways to Get More
The simplest strategy is to add one high-potassium fruit to a meal you already eat. Sliced kiwi on yogurt, a handful of dried apricots as an afternoon snack, or a glass of pomegranate juice with breakfast can each add 400 to 750 mg without requiring any recipe changes.
Smoothies are another easy vehicle. Blending a banana with a cup of kiwi gives you over 1,000 mg in a single drink. Toss in a few dried dates and you’re approaching half your daily target from one glass. Cooked plantains work as a side dish at dinner, prepared the same way you’d make pan-fried potatoes, and a single one covers about 40% of the daily recommendation for men.
If you eat a variety of fruits throughout the day rather than relying on one, you’ll hit your potassium target more easily. A breakfast kiwi, a mid-morning handful of dried apricots, and a plantain at dinner could bring in over 2,500 mg from fruit alone, before counting any vegetables, beans, or other foods in your diet.
