There are immense benefits of foods rich in potassium. The mineral ranks third in the body’s mineral composition. Maintaining electrolyte balance in the body is a major function of potassium. Additionally, you need this mineral for the proper function of the heart, brain, kidneys, and muscles.

The lack of potassium in the body (also called hypokalemia) can cause palpitations, severe headaches, and other complications. This article discusses the importance of potassium in foods, the recommended intake, and dietary sources of potassium. Scroll down and take a look.

The adequate intake of potassium is 1600 to 2000 milligrams per day. This includes the potassium you get through foods and supplements combined.

One great way to meet this requirement is by taking foods rich in potassium.

A cup of white beans contains 3636 mg of potassium and 673 calories (meets 104% of your daily potassium requirement).

White beans are also a great source of fiber and folate – while the former improves digestive health, the latter is good for brain health and is crucial during pregnancy as well.

You can add white beans to your evening soup.

As per a study conducted by Purdue University, adequate dietary intake of potassium can also slow down the progression of kidney disease (1).

2. Dried Apricots

A serving of dried apricots contains 65 mg of potassium and 120 calories.

Dried apricots are also quite rich in non-heme iron, the deficiency of which can cause anemia.

You can add them to your oatmeal, breakfast smoothie, with a handful of almonds, or evening fruit salad.

3. Beet Greens

A cup of beet greens contains 1309 mg of potassium and 39 calories (meets 43% of your daily potassium requirement).

The zinc in beet greens helps boost immunity. It also strengthens your hair.

Beet greens can be added to your evening vegetable salad.

4. Prunes

A cup of prunes contains 290 mg of potassium and 100 calories.

Also being a great source of vitamin A, prunes help boost vision health and prevent eye ailments like dry eyes and macular degeneration and cataracts.

An avocado contains 975 mg of potassium and 322 calories (meets 28% of your daily potassium requirement). A typical serving is about ¼ of an avocado.

Apart from being rich in potassium, avocado is the only fruit offering a good amount of the healthy monounsaturated fatty acids (which are known to reduce cholesterol levels and protect the heart).

You can eat the fruit as it is or slice it and add to your breakfast toast.

7. Salmon

Half a fillet of salmon (about 3 ounces) contains 392 mg of potassium and 180 calories.

You can include salmon in salads or with cooked grains and vegetables for dinner.

8. Banana

One large banana (136 grams) contains 487 mg of potassium and 121 calories (meets 14% of your daily potassium requirement).

Bananas also offer an excellent energy boost. And the fiber in them improves digestive health.

You can simply have a banana with your morning breakfast or in the evening as a snack. Even a banana smoothie would work great.

According to a report by the Colorado State University, potassium is also required for muscle contraction and the proper communication between muscles and nerves (2).

9. Sweet Potatoes

A cup of sweet potatoes (133 g) contains 448 mg of potassium and 114 calories (meets 13% of your daily potassium requirement).

Given that sweet potatoes are low in glycemic index and high in fiber, these veggies can work great for improving diabetes conditions too. A ½ cup serving is generally recommended.

You can prepare your favorite curry using potatoes. Or chop and add them to your evening salad.

10. Acorn Squash

A cup of acorn squash cubes contains 896 mg of potassium and 115 calories.

One cup of carrot juice (236 g) contains 689 mg of potassium and 94 calories (meets 20% of your daily potassium requirement).

Carrots are super rich in vitamin A and other powerful antioxidants like beta-carotene, lutein, and zeaxanthin – all of which considerably boost eye health. The antioxidants also help fight cancer.

12. Coconut Water

A cup of coconut water (240 g) contains 600 mg of potassium and 46 calories (meets 17% of your daily potassium requirement).

Coconut water is also known to lower blood sugar levels, thereby benefiting diabetics. The water also lowers blood cholesterol levels, and this can promote heart health as well.

Coconuts are found in abundance – have coconut water every day.

13. Pomegranate

A pomegranate (282 g) contains 666 mg of potassium and 234 calories (meets 19% of your daily potassium requirement).

Pomegranates are also a rich source of flavonols, antioxidants that help fight inflammation and related conditions like arthritis. These antioxidants in pomegranates can also improve memory.

You can have pomegranate seeds along with yogurt – that would make for a great afternoon snack.

14. Yogurt

A container of plain whole milk yogurt (227 g) contains 352 mg of potassium and 138 calories (meets 10% of your daily potassium requirement).

You can simply include Swiss chard in your vegetable salad every evening.

So yes, why are we talking about these foods? Is potassium so important? Why?

What Are The Benefits Of Taking Enough Potassium?

The most important benefit of potassium-rich foods is improved heart health. Potassium ensures your heart rhythm is healthy. It also lowers blood pressure, and this can prevent heart attacks.

Here are the benefits in a little detail.

1. Boosts Heart Health

Potassium plays an important role in maintaining heart rhythm. It also reduces the risk of stroke, as per studies. Research also shows that a diet high in potassium can help lower blood pressure, which is another major contributor to heart disease.

2. Reduces Cramps

Potassium-rich foods also lead to reduced muscle cramping and increased muscle strength. The mineral also helps alleviate cramps associated with premenstrual syndrome.

3. Helps Prevent Osteoporosis

Increased potassium intake has also been associated with a reduced risk of osteoporosis – the mineral helps preserve bones and prevent bone-related issues (3).

4. Reduces The Appearance Of Cellulite

Cellulite is caused by the stretching of the elastic tissue with a fat layer beneath – and potassium helps flush out the excess fluid from the cells. This, along with a low-fat diet and exercise, can help reduce cellulite.

5. Improves The Processing Of Food

Potassium also helps your body process and utilize the carbs you consume. This invariably boosts overall health.

Potassium not only helps maintain the electrolyte balance of your body but is also crucial for the proper functioning of your heart, brain, muscles and kidney. Coconut water, pomegranate, banana, spinach, carrots, and beet greens are some of the potassium-rich foods that you can include in your diet to avoid its deficiency. Having a balanced diet with regular exercise would help keep you fit and avoid many health complications in the long run.
