If you’ve ever looked up how to lower your blood pressure, reduce muscle cramps, or support heart health, chances are potassium popped up as an essential nutrient. But even though it’s crucial, most people don’t get nearly enough of it in their daily diet.
So the big question is — which food is highest in potassium? And what other options can help you meet your needs naturally without relying on supplements?
Let’s explore the top potassium-rich foods, why your body needs this mineral, signs of low potassium, and how to add more into your meals without overthinking it.
Why Potassium Matters More Than You Think
Potassium is an electrolyte that helps regulate fluid balance, muscle contractions, and nerve signals. It’s also vital for your heart — helping to control blood pressure and reduce the risk of stroke.
Your kidneys are responsible for maintaining the right potassium levels in your body. If levels drop too low (hypokalemia), it can cause weakness, fatigue, cramps, irregular heartbeat, or even serious complications. If levels rise too high (hyperkalemia), it can also be dangerous, though this is rare and usually occurs in people with kidney problems.
The recommended daily intake for potassium is about 2,600 mg for women and 3,400 mg for men, though this may vary depending on health conditions.
So, Which Food Has the Most Potassium?
The surprising winner: Avocados.
A medium avocado can contain up to 975 mg of potassium — that’s more than a banana. It’s also rich in heart-healthy fats, fiber, and antioxidants, making it a powerhouse food for overall wellness.
But if you’re not an avocado fan, don’t worry — there are plenty of other options.
Top 15 Foods High in Potassium (With Approximate Values)
1. Avocados – 975 mg per medium fruitCreamy, versatile, and packed with good fats. Great in salads, sandwiches, or mashed on toast.
2. Sweet Potatoes – 540–700 mg per medium potato
They’re not just a tasty side dish — they also come with fiber, beta-carotene, and antioxidants.
3. Spinach (Cooked) – 840 mg per cup
When cooked, spinach shrinks, meaning you get a lot more potassium per bite. Add it to pasta, eggs, or smoothies.
4. Bananas – 420 mg per medium banana
5. White Beans – 1,000 mg per cup
One of the highest sources among plant-based foods. Excellent in soups, stews, or tossed into grain bowls.
6. Beet Greens – 1,300 mg per cooked cup
Often overlooked, beet greens are packed with potassium, calcium, and fiber. Don’t throw them out!
7. Yogurt (Plain, Low-Fat) – 570 mg per cup
8. Coconut Water – 600 mg per cup
Naturally hydrating and full of electrolytes — just watch for added sugar in flavored varieties.
9. Tomato Paste – 650 mg per quarter cup
Concentrated tomatoes mean more potassium per spoonful. Add it to sauces, chili, or soups.
10. Butternut Squash – 580 mg per cup (cooked)
Slightly sweet and full of potassium and vitamin A. Try it roasted or in soups.
11.Prunes (Dried Plums) – 640 mg per half cup
12. Edamame – 675 mg per cup
13. Salmon (Wild-Caught) – 570 mg per 3 oz

Affordable, filling, and packed with nutrients. Use in curries, salads, or soups.
15. Pomegranates – 660 mg per fruit
These ruby seeds are rich in antioxidants and help deliver a solid potassium hit.
How to Add More Potassium to Your Diet
You don’t need to memorize every milligram. Just focus on a variety of whole foods, especially fruits, vegetables, legumes, and dairy. Here are some practical tips:
- Add avocado slices to your toast or lunch bowl
- Swap your regular potato for a baked sweet potato
- Use white beans in pasta or grain salads
- Choose plain yogurt over sugary versions for breakfast
- Keep bananas or prunes as grab-and-go snacks
- Make smoothies with spinach, banana, and coconut water
- Use tomato paste to enrich soups, stews, or sauces
- Snack on edamame instead of chips
Watch Your Balance — Especially if You Have Kidney Issues
While potassium is crucial, too much can be harmful for people with kidney disease or those on certain medications like ACE inhibitors or potassium-sparing diuretics. If that applies to you, talk to your doctor before loading up on potassium-rich foods.
In those cases, your potassium levels might need to be monitored, and certain foods might need to be eaten in moderation.
Potassium Isn’t Just About One Food — It’s About the Big Picture
While it’s great to know the top foods, your overall eating pattern matters most. If you’re eating a mix of vegetables, fruits, legumes, nuts, seeds, and lean proteins — chances are you’re on the right track.
What’s more, potassium doesn’t work alone. It works with sodium to balance fluids, and with magnesium and calcium to support muscles and nerves. So, focusing on a nutrient-dense diet — rather than just one mineral — is the most sustainable way to feel better and stay healthier long-term.
Final Thoughts
So, which food is highest in potassium? White beans and beet greens top the list, but avocados, sweet potatoes, and bananas are close behind — and often easier to eat daily. The key is variety.
Potassium plays a powerful role in keeping your heart steady, your muscles strong, and your nerves calm. And the best part? You don’t need pills or powders — just real, wholesome food.
Whether you're eating avocado toast, sipping coconut water, or loading your plate with spinach and squash, you’re giving your body what it needs to thrive.
Let your meals work for you — one potassium-packed bite at a time.
