23 Foods That Have More Potassium Than a Banana
Shake up your post-run snack with these tasty swaps.
When you think of the best sources of potassium, what's the first food that comes to mind? That's right, bananas. They're incredibly popular, with Statista finding that Americans consumed about 27 pounds of the yellow fruit per person in 2021. That's pretty—dare we say—bananas.
But what if you're allergic to bananas, or just straight up don't like them? Well, you might actually be in luck. As it turns out, they're not as high in potassium compared to some other foods. For reference, each medium banana provides 422 mg of the mineral, which is about 9% of the recommended daily value (DV)—but more on that later. So, yes, while the banana is known for its ability to help keep potassium levels in check, it's not the only way you can get your recommended dose of the much-needed mineral—which is important, considering just how much of the heavy lifting potassium does when it comes to your health.
According to Rima Kleiner, MS, RDN, potassium is responsible for critical functions within the body, including the regulation of blood pressure, neural communication, muscle contractions, fluid regulation, shuttling nutrients into cells, and taking waste out. "[Additionally,] potassium-rich diets may help counter the effects of high sodium, lower blood pressure, help reduce the risk of stroke and kidney stones, and may help prevent osteoporosis.
"The average adult will need around 4,700 mg a day," Kleiner explains, noting that people with compromised kidney function or those taking blood pressure medications should confirm those numbers with their doctor before making changes to their diets. "While too low potassium (hypokalemia) or potassium deficiency is rare, there may be instances where you lose potassium due to rapid fluid loss (like chronic diarrhea, chronic vomiting or diuretic use)," she says.
All of that being said, extremes in either direction can be extremely dangerous for your heart, according to Stephanie Nelson, MS, RD, Lead Nutrition Scientist at MyFitnessPal, who says nailing down the correct amount of the mineral can have benefits "associated with lower risk of heart disease, lower blood pressure, and better bone health."
Here's what the experts—including Kleiner, Nelson, Natalie Rizzo, MS, RD, founder of Greenletes, and Roxana Ehsani, MS, RD, CSSD, LDN— say you can eat instead of a banana when you're looking to increase your potassium intake. (The potassium levels below are pulled from the USDA nutrient database.)
