If you've 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 rich 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: 28% Daily Value (DV)

Yogurt also provides fat, calcium, protein and potassium, making it bone- and muscle-friendly. A 1-cup serving of yogurt provides 379 milligrams or 8 percent of the DV for potassium.

20. Milk: 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 322 milligrams or 7 percent of the DV.

21. Sunflower Seeds: 5% DV

Nuts and seeds add flavor, fat, plant-based protein and antioxidants to snacks and salads. And because they're high in healthy fats, a small serving goes a long way in helping you feel fuller for longer.
