Bananas may be known as potassium-rich foods, but you can also get potassium from avocados, sweet potatoes, spinach, coconut water, and other delicious food and drinks.
Potassium is a vital mineral and electrolyte that your body needs to maintain normal blood pressure, transport nutrients into your cells, and support healthy nerve and muscle function (1).
It’s considered an essential nutrient because your body can’t produce it. Therefore, you must get potassium from foods to meet your recommended daily needs, also known as the Daily Value (DV) (2).
However, most people don’t get enough potassium through their diets. It’s estimated that less than 0.015% of American adults meet their daily potassium needs (3).
Since a medium banana contains around 9% of the DV for this mineral, most people consider it the go-to food to increase their potassium intake. However, bananas are not the only good source of potassium (4).
A list of high-potassium foods
Share on PinterestHere are 18 foods that pack more potassium than a banana.
1. Avocados
Avocados are packed with healthy fats, vitamin K, and folate.
Half an avocado without the skin and seed (68 grams) contains 345 mg of potassium, or 7% of the DV. If you eat a whole avocado, you’ll get almost 15% of the DV at once (5).
What’s more, avocados may benefit people with high blood pressure, who often need to increase their potassium and reduce their sodium intake. Like most other fruits, avocados are low in sodium, with half an avocado providing just 0.2% of the DV (1, 3, 5).
SummaryAvocados are packed with nutrients, and one avocado provides roughly 15% of your daily potassium needs. They’re also rich in vitamin K and folate.
2. Sweet potatoes
Sweet potatoes are often used as an alternative to white potatoes.
They’re an exceptionally nutritious way to support your potassium intake. A 1-cup (328-gram) serving of mashed sweet potato boasts 16% of the DV (6).
What’s more, sweet potatoes are low in fat, offer a small amount of protein, and are a good source of complex carbs and fiber.
They’re also an excellent source of vitamin A, which is critical for vision. The same serving of sweet potatoes provides more than 200% of the DV of vitamin A (1, 6, 7).
For a balanced and filling meal, you can pair these delicious root vegetables with a protein source such as beans or meat, some dark greens or colorful vegetables, and a little fat.
SummarySweet potatoes boast 16% of the DV for potassium in just 1 mashed cup (328 grams), plus some protein, fiber, and vitamin A.
3. Spinach
Spinach is one of the most nutrient-dense vegetables.
Just 1 cup (190 grams) of frozen spinach packs 12% of the DV for potassium. Similarly, about 3 cups (90 grams) of raw spinach contain roughly 11% of the DV (8, 9).

How much potassium do you need?
Like other vitamins and minerals, potassium is a micronutrient, meaning that you need to consume it only in small amounts — think milligrams (mg).
As previously mentioned, vitamin and mineral needs are measured according to their Daily Values (DV), the recommended amounts to consume per day (2).
The DV for potassium for healthy individuals is 4,700 mg. You can consume this amount by following a wholesome, varied diet (2).
Many Western diets are low in potassium and high in sodium — two factors that can increase your risk of heart disease. However, eating foods from the list above may help you increase your potassium intake (44).
