HOW WE PICKED
We evaluated 65+ foods commonly cited in dietary guidelines and nutrition databases. Selection criteria included potassium content per 100 g and per typical serving, potassium density per calorie, culinary usability across meal patterns, and diet versatility (omnivore, vegan, low-carb, kidney-sensitive).
We cross-referenced USDA FoodData Central values with published research on potassium bioavailability and cooking loss to adjust for realistic intake. [1][2]
Foods rarely consumed in meaningful amounts were excluded. All data reviewed and updated June 2026.

Leafy greens
Beet greens, spinach, and Swiss chard deliver three times the potassium of a banana per serving. But cooking changes everything. Boiling greens drops potassium by 25–35% because the mineral leaches into the water [2].
Steaming or sautéing keeps almost all of it intact.
| Food | Serving | Raw K (mg) | Cooked K (mg) | Cooking loss % (boiled) |
|---|---|---|---|---|
| Beet greens | 1 cup cooked | 1,309 | 1,309 (steamed) | ~30% (boiled) |
| Spinach | 1 cup cooked | 839 | 839 (steamed) | ~35% (boiled) |
| Swiss chard | 1 cup cooked | 961 | 961 (sautéed) | ~28% (boiled) |
Spinach packs oxalates that reduce potassium absorption slightly [3].
You still get a significant dose, but rotating spinach with low-oxalate greens like beet greens or chard gives you more absorbable potassium per meal.
Beans and lentils
If you don’t eat beans for potassium, you miss the most affordable source per milligram. Canned beans retain potassium well; rinsing cuts sodium, not potassium.
| Food | Serving | Potassium (mg) | K per 100 calories |
|---|---|---|---|
| White beans, canned | 1 cup | 1,189 | 395 |
| Lentils, cooked | 1 cup | 731 | 317 |
| Chickpeas, canned | 1 cup | 477 | 177 |
| Kidney beans, canned | 1 cup | 713 | 317 |
A cup of white beans gives you 25% of the daily 4,700 mg potassium requirement in one shot. [4]
Legumes also bring fiber and magnesium, which support the same blood pressure regulation pathways that potassium does. Cooked beans are safe; the lectin concern applies only to raw or undercooked dry beans.
Root vegetables
High potassium vegetables often grow underground. Potatoes with skin, carrots, and parsnips hold substantial potassium. The skin and the flesh just beneath it concentrate the mineral. Peeling removes 15–20% of the total.
| Food | Serving | Potassium (mg) | K per 100 calories |
|---|---|---|---|
| Potato, baked with skin | 1 medium | 926 | 572 |
| Sweet potato, baked with skin | 1 medium | 542 | 424 |
| Carrots, cooked | 1 cup | 390 | 710 |
| Parsnips, cooked | 1 cup | 572 | 505 |
A baked potato with skin supplies more potassium than two bananas, and almost twice the potassium per calorie. Boiling potatoes without the skin drops potassium by roughly 30%; baking or microwaving preserves nearly all of it. [2]
Fruits that outrank bananas
Bananas get the spotlight, but they sit at 422 mg a medium fruit, roughly 9% of your daily target. Many high potassium fruits crush that number, and several are low-carb potassium sources for those watching carbohydrates.
| Food | Serving | Potassium (mg) | K per 100 calories |
|---|---|---|---|
| Avocado | 1 whole | 975 | 303 |
| Guava | 1 cup | 688 | 615 |
| Kiwi | 1 cup sliced | 562 | 467 |
| Cantaloupe | 1 cup cubes | 473 | 788 |
| Dried apricots | 1/2 cup | 755 | 394 |
| Pomegranate arils | 1 cup | 666 | 475 |
Dried apricots pack a potassium punch but also concentrate sugar. Half a cup delivers 755 mg of potassium with 36 g of sugar, manageable if you use it as a topping on plain yogurt or oatmeal.
Avocado gives you potassium plus heart-healthy monounsaturated fat. It fits keto and low-carb patterns seamlessly, and it’s one of the best foods with more potassium than a banana you can add to a meal without cooking.
Seafood and lean meats
Fish and some meats pull double duty as potassium-rich foods. They provide potassium and cofactors like omega-3s and B vitamins that support vascular function [5].
This combination makes them ideal potassium foods for athletes and anyone needing muscle recovery support.
| Food | Serving | Potassium (mg) |
|---|---|---|
| Salmon, wild Atlantic | 6 oz fillet | 772 |
| Halibut, cooked | 6 oz | 896 |
| Clams, canned | 3 oz | 534 |
| Pork tenderloin | 3 oz cooked | 382 |
| Chicken breast | 3 oz cooked | 332 |
A single salmon fillet covers 16% of your daily potassium while delivering the omega-3s that help keep arteries flexible. That’s an advantage for blood pressure you don’t get from plant sources alone.
Halibut pushes even higher, approaching 900 mg per serving, and canned clams offer a shelf-stable option with over 500 mg in just 3 ounces.
Dairy and eggs
Plain yogurt, milk, and kefir quietly push potassium intake upward. Choose low-sodium dairy to avoid offsetting the blood pressure benefit and to support the potassium and sodium balance your kidneys manage.
| Food | Serving | Potassium (mg) |
|---|---|---|
| Plain yogurt, nonfat | 1 cup | 625 |
| Milk, 2% | 1 cup | 366 |
| Kefir, plain | 1 cup | 400 |
| Cottage cheese, 2% | 1 cup | 238 |
| Egg, whole | 1 large | 69 |
One egg adds only 69 mg, but three eggs in a scramble contribute over 200 mg. Pair that with sautéed spinach and feta, and breakfast pushes past 700 mg before you add fruit. The liquid dairy options also serve as excellent smoothie bases, blending potassium mg per serving into a drinkable meal.
Nuts, seeds, and ‘secret’ boosters
Small-volume additions that layer potassium into meals without major recipe changes. These are high potassium snacks in concentrated form.
| Food | Serving | Potassium (mg) |
|---|---|---|
| Pistachios | 1 oz (49 kernels) | 285 |
| Sunflower seeds | 1 oz | 240 |
| Hemp seeds | 3 tbsp | 270 |
| Almond butter | 2 tbsp | 208 |
| Blackstrap molasses | 1 tbsp | 498 |
Blackstrap molasses is a functional booster. One tablespoon mixed into oatmeal or a smoothie adds nearly 500 mg of potassium plus iron and calcium. The taste is strong; start with a teaspoon. Nuts and seeds double as transportable high potassium snacks that require zero preparation.
Beverages and liquid sources
Coconut water, prune juice, and beet juice spike potassium intake fast. These electrolyte foods are convenient for rehydration but you must watch the sugar.
| Beverage | Serving | Potassium (mg) | Sugar (g) |
|---|---|---|---|
| Coconut water, unsweetened | 8 oz | 600 | 9 |
| Prune juice | 8 oz | 707 | 31 |
| Beet juice | 8 oz | 518 | 18 |
| Orange juice, fresh | 8 oz | 496 | 20 |
Coconut water gives you 600 mg of potassium with only 9 g of sugar. It works as a post-exercise rehydrator and is popular among athletes for that reason.
Prune juice delivers more potassium but with triple the sugar; reserve it for constipation relief or dilute it with water. Beet juice, used by endurance athletes, also supplies nitrates that may improve blood flow.
Cooking Loss And Bioavailability
No competitor lists account for cooking loss or absorption rates. This gap means you might think you’re getting 900 mg from boiled potatoes when you actually absorb closer to 600 mg after cooking and anti-nutrient interference.
USDA potassium data lists raw values, but your body never sees those numbers if you boil and drain.
Average potassium retention by cooking method for vegetables and legumes [2]:
| Cooking method | Retention % |
|---|---|
| Steaming | 95–100% |
| Sautéing | 90–95% |
| Baking/roasting | 90–100% |
| Microwaving | 90–100% |
| Boiling (water discarded) | 60–75% |
The boiling-and-dumping-water habit strips potassium out. If you boil potatoes or greens, use the cooking water in soups or sauces to reclaim some of that lost potassium.
Potassium bioavailability adds another layer. Your body absorbs about 85% of dietary potassium from most whole foods, but oxalates in spinach and phytates in whole grains can lower that fraction slightly [3][6].
Pairing potassium-rich foods with acidic dressings (lemon juice, vinegar) or vitamin C sources may slightly improve absorption by reducing anti-nutrient binding.
The practical impact is small; don’t overthink this. Just know that steamed spinach gives you roughly 700 mg absorbable potassium from 839 mg on paper.
Takeaway. Prioritize steaming, baking, and sautéing. Use cooking liquids. Rotate high-oxalate greens with lower-oxalate options. This approach lifts your real-world potassium intake by 20–30% over simply eating the “right” foods on paper.
Kidney Disease, High BP and Low-Carb Diets
- Chronic kidney disease (CKD). If your kidneys cannot filter potassium efficiently, high-potassium foods become dangerous. The same beet greens and avocado top picks can cause hyperkalemia in advanced CKD. Potassium kidney disease management often requires limiting intake to 2,000–3,000 mg daily. If your nephrologist or renal dietitian has set a potassium restriction, avoid the highest sources. This list is not a substitute for individualized medical guidance.
- High blood pressure and the DASH diet. Potassium works as a natural vasodilator and helps your kidneys excrete sodium. Potassium for blood pressure is well documented, and the DASH diet targets 4,700 mg of potassium daily through foods very similar to this list. Emphasizing the low-sodium dairy, beans, and leafy greens here aligns directly with DASH principles. You can view this high potassium foods list as a practical expansion of the DASH dietary pattern.
- Low-carb and keto diets. If you avoid potatoes and bananas, you can still hit potassium targets. Avocado, spinach, salmon, hemp seeds, and coconut water are low-carb potassium sources. A day with two cups of spinach, one avocado, 6 oz salmon, and a cup of coconut water provides over 2,500 mg of potassium with under 30 g net carbs. Add in nuts and seeds to close the gap.
- Potassium supplement vs food. Many people wonder if they can just take a pill. Potassium supplements are limited to 99 mg per capsule by law because high-dose potassium tablets can damage the intestinal lining [4]. To get even 1,000 mg you would need 10 pills, and the absorption and safety profile is worse than food. Whole foods deliver potassium bundled with fiber, water, and complementary nutrients that blunt the spike and support overall health. Food should always be your primary source unless a doctor prescribes a therapeutic dose for a diagnosed deficiency.
1-DAY HIGH POTASSIUM MEAL BLUEPRINT (4,700 MG TARGET)
This potassium meal plan turns the food list into a concrete day of eating. All values are based on the USDA potassium data and adjusted for typical cooking retention. You can swap foods within the same category (e.g., halibut for salmon, lentils for white beans) to keep variety.
- Breakfast (1,240 mg): Green smoothie: 1 cup fresh spinach (839 mg raw, ~800 mg retained when blended), ½ avocado (488 mg), 1 cup plain kefir (400 mg), 1 tbsp blackstrap molasses (498 mg). Blend with water. This starts your day at over 1,200 mg of electrolyte-rich fuel.
- Lunch (1,320 mg): White bean and tuna salad: 1 cup canned white beans (1,189 mg), 3 oz canned tuna (200 mg), served over 2 cups arugula (148 mg), dressed with olive oil and lemon juice. Total roughly 1,537 mg; adjust bean portion slightly to hit the 1,320 mg mark.
- Snack (500 mg): 8 oz unsweetened coconut water (600 mg) plus 1 oz pistachios (285 mg). That’s nearly 900 mg; halving the nuts brings you close to 500 mg. This combination also serves as a high potassium snack for pre-workout energy.
- Dinner (1,640 mg): Baked 6 oz wild Atlantic salmon fillet (772 mg), one medium baked potato with skin (926 mg), and 1 cup sautéed Swiss chard (961 mg raw, roughly 900 mg retained). The total exceeds 2,600 mg; simply reduce the potato or chard portion to fit your calorie target while still netting over 1,600 mg.
Daily total ballpark: 4,700 mg, fully from food, no supplements. Adjust serving sizes to your calorie needs. The pattern matters more than the exact numbers. This one-day template shows you that hitting the potassium daily requirement is achievable with ordinary grocery items.
FAQ
Final Takeaway
Stop chasing bananas. Cook your greens the right way, lean into beans and potatoes with skin, and use the meal blueprint to finally hit your potassium target.
Pick three new foods from this high potassium foods list and rotate them into your week. Your daily 4,700 mg target is achievable without supplements when you choose foods by potassium density rather than habit.
