The Importance of Potassium for Good Health
Getting enough potassium is crucial for overall health and wellbeing. As an essential electrolyte, potassium is vital for proper muscle and nerve function, maintaining fluid balance, supporting bone density, regulating blood pressure, and much more. Despite its importance, many people do not get adequate potassium in their diets.
Recommended Daily Intake of Potassium
The 2020-2025 Dietary Guidelines for Americans recommend that adults consume at least 4,700mg of potassium per day as part of a healthy eating pattern. Unfortunately, research shows that most Americans only get about half that amount on average.
Consequences of Low Potassium Levels
Consistently failing to meet potassium needs can contribute to unwanted health consequences over time. Some problems linked to potassium deficiency include:
- High blood pressure
- Increased risk of kidney stones
- Higher risk of osteoporosis and bone fractures
- Muscle cramps and spasms
- Fatigue and weakness
- Irregular heartbeat
Making a conscious effort to include more high potassium foods in your meals and snacks can help safeguard against these issues.
10 Potassium Powerhouse Foods
While bananas tend to dominate conversations about dietary sources of potassium, many other nutritious and delicious foods also deliver ample amounts. These 10 options can help you meet your potassium needs and make progress toward better health:
1. Baked Potatoes
Baked potatoes are potassium superstars. One large russet potato with the skin provides 926 milligrams of potassium. Potatoes are also highly nutritious, providing fiber, vitamin C, vitamin B6, and resistant starch.
2. Prunes
Tasty prunes are dried plums that contain many key nutrients. Just 1⁄2 cup of prunes offers 654mg of potassium. Prunes also supply antioxidants, vitamin K, copper, boron, and fiber.
3. White Beans
Incorporating more beans and lentils into your diet is an easy way to increase potassium intake. One cup of canned white beans packs in 1004mg. Beans are also loaded with plant-based protein, magnesium, folate, iron, and zinc.
4. Avocados
Creamy, versatile avocados provide a hefty dose of heart-healthy potassium. One medium avocado contains 1067mg of potassium along with fiber, vitamin K, vitamin C, magnesium and healthy fats.
5. Spinach
Leafy green spinach is one of the most potassium-rich vegetables available. A half-cup of cooked spinach contains a stellar 839mg of potassium plus vitamins A, C and K. Use spinach generously in salads, scrambles, casseroles and soups.
6. Sweet Potatoes
Like white potatoes, sweet potatoes excel when it comes to potassium. One large baked sweet potato with skin provides 542mg. Sweet potatoes also contain ample vitamin A, vitamin C, manganese and antioxidants.
7. Tomato Sauce
Simmering tomatoes into sauce concentrates their nutrient content. Just half a cup of tomato sauce delivers 494mg potassium, making it easy to add to pasta, pizza and more. Tomatoes are also rich in lycopene, an antioxidant that promotes heart health.
8. Beet Greens
While beets get more attention, beet greens are the real potassium powerhouses. One cup of cooked beet greens contains a whopping 1309mg potassium along with healthy amounts of vitamins A, C, E, K and magnesium.
9. Yogurt
Plain yogurt naturally contains potassium and makes a versatile high-potassium ingredient to include in smoothies, parfaits, dips and dressings. One cup of nonfat yogurt provides 573mg of potassium plus calcium, probiotics and protein.
10. Fish
Many varieties of fresh and canned fish provide considerable amounts of potassium. A 3-ounce serving of baked salmon contains 534mg potassium, for example. Halibut, snapper, tuna and cod are other fish high in this essential nutrient.
