14 Potassium-Rich Foods to Add to Your Diet

Potassium is a major dietary mineral that helps balance your body's pH and body fluids. It's important for normal blood pressure regulation (it works in opposition to sodium). It's also needed for normal muscle growth, and for the nervous system and brain function. According to the Institute of Medicine, the average adult should consume about 4,700 milligrams of potassium every day.

Your body's potassium levels may be affected by kidney disease, diabetes, vomiting, fluctuating hormone levels, or as a side effect of certain medications. It's best to get your potassium from the foods you eat; please don't take potassium supplements without speaking with your health care provider first.

Fruits and vegetables are the richest sources of potassium, so you may be getting plenty in your diet right now. But if you're like most people who eat a Western diet and get fewer than five servings of fruits and vegetables a day, there's a good chance you could use more of this mighty mineral. 

To boost your intake, consider adding more of these 14 foods to your diet.

Baked potatoes rock the potassium world. One medium baked potato packs 926 milligrams potassium, more than a quarter your daily requirement. That potato is also an excellent source of vitamin C and vitamin B6. It also contains 4.3 grams of protein and 3.8 grams of fiber for 161 calories.


Beet Greens

If you're tossing beet greens into the compost instead of sautéing them, you're missing out on a ton of good nutrition. A cup of these cooked greens has over 1,310 milligrams potassium, plenty of other minerals, as well as four grams of fiber, 35 milligrams vitamin C, and 11,000 International Units of vitamin A.

Dry beans of any kind are rich in potassium, but white beans have the most: For example, a 1/2 cup serving of lima beans delivers 477 milligrams. Beans are also an excellent source of minerals in general, as well as fiber—that serving of lima beans has 6.5 grams and just over 100 calories.

If opting for canned beans, be sure to rinse off the excess sodium before eating or preparing them.


Nonfat Yogurt

Plain yogurt

Plain nonfat yogurt is a good source of potassium with more than 500 milligrams in 1 cup of yogurt. Low-fat yogurt is also a good source, but yogurt made with whole milk isn't quite as impressive potassium-wise.

It's also important to note Greek yogurt isn't nearly as potassium-rich as plain old nonfat yogurt. In that 150-calorie cup of yogurt, you'll also get plenty of calcium, protein, vitamin D, and the healthy bacteria known as probiotics.


Baked Sweet Potatoes

That sweet spud also packs about 4 grams fiber but only 100 calories.

Most fish, such as salmon and tuna, will supply you with some potassium, but halibut is the top dog, so to speak. A 5-ounce baked halibut filet has 500 milligrams potassium plus several minerals, essential fatty acids, and niacin.

Clams are best known as a source of zinc, a mineral that's important for so many chemical reactions to occur in the body. But clams are also an excellent source of potassium, with 3 ounces containing around 530 milligrams. Clams are also low in calories, high in protein, and an excellent source of iron.


Tomato Products

Tomatoes are a fair source of potassium, but when they're cooked and concentrated into sauces, stews, and paste, the amount of potassium goes up quite a bit.
