Potassium is a vital mineral and electrolyte for your body.
It helps maintain normal blood pressure, transports nutrients into your cells, and supports healthy nerve and muscle function.
The adequate intake (AI) for potassium is 4,700 mg in healthy individuals, but unfortunately, most people don’t get enough potassium through their diets.
Some people turn to bananas, as these are well known for being high in potassium, one medium-sized banana typically containing 422 mg or 9% of the adequate intake.
But bananas are not the only potassium heroes.
Here are 15 foods that pack more potassium than a banana.
Avocados have become extremely popular and trendy — and with good reason.

Packed with good fats, avocados are also a particularly great source of vitamin K and folate. One-half of an avocado (100 grams) contains 487 mg of potassium or 10% of the adequate intake. If you eat a whole avocado, you’d get 20% of your daily potassium needs at once.
What’s more, avocados may help people with high blood pressure, who are often told to increase their potassium and reduce their salt (sodium) intake.
This advice stems from a study called Dietary Approaches to Stop Hypertension (DASH). Further research has verified the benefits of potassium in reducing blood pressure.
Avocados, like most fruit, are low in sodium. Half an avocado provides 7 mg or just 0.5% of your recommended dietary intake (RDI) of sodium.
Summary: Avocados are jam-packed with nutrients — only half a fruit gets you 10% of your daily potassium needs. They’re also rich in vitamin K and folate and may even help lower your blood pressure.
2. Sweet potatoes
Like avocados, sweet potatoes have become increasingly popular and are often used as an alternative to potatoes.
They’re an especially nutritious way of supporting your potassium intake — one medium-sized sweet potato contains 541 mg or 12% of your potassium adequate intake.
What’s more, sweet potatoes are low in fat, pack a small amount of protein, and are a good source of complex carbohydrates and fiber. They’re also an excellent source of vitamin A, as one sweet potato provides over 400% of your recommended dietary intake.

One cup (156 grams) of frozen spinach contains 540 mg of potassium or roughly 12% of the adequate intake.
It also packs a punch with other nutrients. The same serving size contains 366% of your recommended dietary intake for vitamin A, 725% for vitamin K, 57% for folate, and 29% for magnesium.
Similarly, about three cups (100 grams) of raw spinach contain 558 mg of potassium, also around 12% of the adequate intake.

Summary: Spinach provides more potassium per serving than a banana — about 12% of the adequate intake per one cup (156 grams) frozen or three cups (100 grams) fresh. This vegetable also packs vitamins A and K, as well as folate and magnesium.
Watermelon is a large, delicious fruit with high water content.
Just two wedges of watermelon (about 1⁄8 of a melon or 572 grams) will give you 640 mg of potassium, just under 14% of the adequate intake.
The same serving size also contains 172 calories, 44 grams of carbohydrates, 3.4 grams of protein, 0.8 grams of fat, and 2.2 grams of fiber.
What’s more, this lush, red melon is a great source of vitamins A and C, as well as magnesium.
Summary: Watermelon is a tasty, summery fruit, just two wedges of which can give you almost 14% of your potassium adequate intake, as well as vitamins A and C at only 172 calories.
5. Coconut water
Coconut water is a fantastic, hydrating drink. You can shop for it online.

Summary: Coconut water is not only a great hydrating drink but also an excellent source of potassium, containing 13% of the adequate intake in just one cup (240 ml). It’s also a good source of magnesium, calcium, sodium, and manganese.
6. White beans
The term white beans can refer to navy (pea) beans, cannellini (white kidney) beans, great northern beans, or lima beans.
Though bananas are lauded for their potassium content, one cup (179 grams) of any of these beans has twice as much potassium as one banana. One cup of cooked white beans gives you 829 mg of potassium — a whopping 18% of the adequate intake.
One cup also provides 28–61% of the recommended dietary intake for various B vitamins. Additionally, white beans are a great source of iron and plant-based protein.

7. Black beans
Black beans, also known as turtle beans, are a staple food in Central and South America.
They’re often used in burritos and soups. You can even purchase them online.
Although white beans may have more potassium than black beans, the latter is still a great source of potassium. One cup (172 grams) of black beans gives you 611 mg or 13% of the adequate intake.
However, as black beans contain phytates that can reduce your body’s absorption of minerals, not all of that potassium may be put to use.
It’s difficult to know how much these phytates may affect the absorption of minerals like potassium, but if you’re using dried beans it’s best to soak them overnight. This step will help reduce the number of phytates.
Summary: Black beans are a versatile food that can provide you with 13% of your potassium adequate intake in one cup (172 grams). Soaking dried beans first may improve mineral absorption, including potassium.
Edamame, traditionally eaten in Japan, is immature soybeans served in the pod.
They too have more potassium in one cup than a banana. One cup (155 grams) provides 676 mg or just over 14% of the adequate intake.
They’re filled with many other nutrients, but most notably contain 121% of the recommended dietary intake for folate per cup (155 grams).
What’s more, they’re a great source of vitamin K, magnesium, and manganese.
Edamame is delicious lightly steamed as an accompaniment to meals.

10. Butternut squash
Butternut squash is sweet-tasting winter squash. While technically a fruit, it’s cooked like a root vegetable.
One cup (205 grams) of butternut squash can give you 582 mg of potassium — over 12% of the adequate intake.
It’s also a great source of vitamins A and C and has smaller amounts of B vitamins, vitamin E, and magnesium.
Butternut squashes can be roasted, boiled, steamed, or chopped up for use in hearty soups.
Summary: Butternut squash is a great source of potassium, boasting 12% of the adequate intake in a single cup (205 grams). This fruit also packs vitamins A and C, as well as smaller amounts of B vitamins, vitamin E, and magnesium.
