If you ever watched the Rick Moranis three-quel Honey, We Shrunk Ourselves, you probably know that bananas are a good source of potassium. (Recap: One of the kids passes out and he needs potassium, and Moranis' son pipes up, "Potassium, potassium, bananas have potassium!")
But while the yellow fruit is often thought of as the main source of the mineral, there are actually plenty of foods with more potassium than bananas.
Potassium is a crucial mineral needed to support kidney and heart health as well as muscle and nerve function, according to the National Institutes of Health (NIH). The mineral is an electrolyte and works with sodium (another electrolyte) to keep fluid levels balanced, according to the University of Michigan.
How Much Potassium Do You Need?
While the NIH recommends a daily potassium intake of 3,400 milligrams and 2,600 milligrams for adults assigned male and female at birth, respectively, the FDA calculates its Daily Value (DV) percentages based on eating 4,700 milligrams of potassium per day. So how much potassium do you really need?
"Aiming for 3,400 to 4,700 milligrams per day is generally regarded as safe and is recommended to decrease the risk of developing chronic diseases where the risk may be modifiable with adequate amounts of dietary potassium [such as high blood pressure]," says Maya Feller, RD, CDN.
Below, find a list of foods high in potassium to add to your shopping cart. Note that the DVs cited below are based on eating 4,700 milligrams of potassium per day.
1. Beet Greens: 1,309 mg, 28% Daily Value (DV)
Rich in a host of nutrients including folate, iron and vitamin C, leafy greens are powerhouses. They're also great sources of potassium, with beet greens taking the lead, providing 28 percent of the Daily Value (DV) per 1 cup.
2. Salmon: 1,067 mg, 23% DV
Not only is salmon an excellent source of lean protein (43 grams per 6 ounces) and heart-healthy omega-3 fatty acids, but it's also one of the best low-carb foods high in potassium.
A 6-ounce serving of cooked wild-caught salmon offers 23 percent of the DV and 6 ounces of cooked farmed salmon has 14 percent of the DV for potassium. Wild-caught salmon has less saturated fat than farmed salmon, but both are healthy options.
3. Cannellini Beans: 1,004 mg, 21% DV
In general, beans pack a punch when it comes to plant-based nutrition, but cannellini beans (also known as white kidney beans) provide the highest amount of potassium in the bean family — 21 percent of the DV per 1 cup cooked.
Using beans as a base for your cooking is a good way to bump up your nutrition, and they go great with any kind of veggie or meat. Try them in these high-protein canned bean recipes.
4. Avocados: 975 mg, 21% DV
Everyone's favorite fatty fruit — yes, avocados are fruit! — packs good-for-you unsaturated fats, vitamin E, fiber and vitamin C and just happens to be one of the best keto foods high in potassium. One whole avocado provides 21 percent of the DV for the nutrient. Avocados are filling and versatile, making them great for breakfast, lunch and dinner. Try them in these avocado recipes that aren't toast or guac.
5. Lima Beans: 969 mg, 21% DV
All beans are high in potassium, but lima beans (also referred to as butterbeans) top the charts. One cup of cooked lima beans has 21 percent of your potassium DV, 23 percent DV for iron, nearly 12 grams of plant-based protein and about 9 grams of satiating fiber. Plus, they have a mild taste and work beautifully in a variety of dishes.
6. Swiss Chard: 960 mg, 20% DV
Another leafy green to add to your potassium list is Swiss chard. Like its beet green friend, Swiss chard is a great low-carb food high in potassium — 1 cup cooked has 20 percent of the DV — and is a good source of non-heme (plant-based) iron and vitamin C. Swiss chard sautés well, making it a popular stir-fry ingredient.
7. Potatoes: 925 mg, 20% DV
Potatoes tend to get a bad rap because of people's fear of carbohydrates. But potatoes — yes, even white ones — are one of the best vegan foods high in potassium and provide a host of nutrients. Baked potatoes with their skin contain 20 percent of the DV for potassium (per medium cooked potato) as well as satiating fiber.
8. Acorn Squash: 896 mg, 19% DV
Thanks to its bright orange color, acorn squash (and its other squash relatives) is high in free-radical-fighting antioxidants, according to Harvard Health Publishing. One cup of cooked acorn squash provides 19 percent of the DV for potassium and 36 percent of the DV for fiber.
9. Pinto Beans: 745.6 mg, 16% DV
Add them to soups, salads, chilis and even sandwiches for a protein, fiber and potassium boost. Just 1 cup of cooked pinto beans provides 16 percent of your potassium DV.
10. Lentils: 730 mg, 16% DV
Similar to beans, lentils are high in plant-based protein, iron and potassium — 1 cup of cooked lentils offers 16 percent of your DV of the mineral. Thanks to their versatility, lentils make a hearty base to any meal, whether it's vegetarian or with meat.
Lentils come in a variety of colors, including green, black, red and yellow, all of which provide slightly different amounts of nutrients. Try them in these high-protein lentil recipes.
11. Tilapia: 646 mg, 14% DV
Tilapia is a mild-tasting white fish that contains a good dose of satiating protein. What's more, a 6-ounce cooked portion contains 14 percent of the DV for potassium. While tilapia does contain some omega-3 fatty acids, other fish, such as salmon, are higher in healthy fats, according to Harvard Health Publishing.
12. Coconut Water: 600 mg, 13% DV
Coconut water is having a moment, and for good reason: It's a great source of electrolytes, including potassium, making it a go-to for hydration. One cup of coconut water contains 13 percent of the DV of the mineral, deeming it a top drink high in potassium. But unlike good ol' H2O, coconut water does contain calories (46 per cup).
Small but mighty, these mushrooms provide fiber, iron and potassium, as well as a satisfying umami flavor when cooked. A cup of cooked white button mushrooms offers 12 percent of the DV for potassium. Mushrooms can easily add nutrition to omelets, stir-fries and pasta dishes. White button mushrooms even provide some vitamin D — 2 percent of the DV per cup — as well as 15 percent of the DV for iron.
14. Kiwi: 561 mg, 12% DV
Kiwi, the tiny sweet fruit that hails from New Zealand, is packed with nutrition, including fiber and vitamin C (185 percent of the DV!). A cup of kiwi also provides 12 percent of the DV for potassium while one fruit contains 5 percent of the DV.

Bright red thanks to lycopene, a powerful antioxidant, tomatoes are packed with nutrients, including vitamin C, iron and potassium. One cup of cooked tomatoes contains 11 percent of the DV for potassium. Cooked tomatoes contain a bit more potassium than ripe tomatoes, but both will add color and nutrition to your plate.
Lycopene found in tomatoes is linked to a lower risk of stroke, according to an October 2012 study in Neurology of more than 1,000 men.
16. Orange Juice: 496 mg, 11% DV
Your morning glass of OJ provides the sugar you need to kick start your day, plus vitamin C and other antioxidants to help support a healthy immune system. Orange juice, a good source of calcium, is also often fortified with vitamin D, and the combination makes OJ good for bone health, according to an October 2014 paper in the Journal of Medicinal Food.
An 8-ounce glass of orange juice provides 11 percent of the DV for potassium. Orange juice is high in sugar (it is a fruit juice, after all) with about 21 grams per cup, so it's important to enjoy it in moderation.
17. Bananas: 487 mg, 10% DV
Although many of us already know bananas have potassium, the fruit is also a good source of fiber and vitamin C. One large banana offers 10 percent of the DV for potassium.

Whole milk is a nutrient powerhouse: It's high in fat, protein and calcium and is often fortified with vitamin D. Milk is also a good source of potassium across all varieties (whole milk, reduced-fat, low-fat and skim). An 8-ounce glass has 7 percent of the DV.
21. Sunflower Seeds: 241 mg, 5% DV
Nuts and seeds add flavor, fat, plant-based protein and antioxidants to snacks and salads.
