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)

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

11. 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).

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.

16. 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.

Yogurt also provides fat, calcium, protein and potassium, making it bone- and muscle-friendly. A 1-cup serving of yogurt provides 8 percent of the DV for potassium.

19. Milk: 322 mg, 7% DV

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.
