Potassium Rich Foods

Quick Highlights

• Potassium is a natural mineral that the body uses in the form of ions to keep cells working properly.
• Too little or too much potassium can cause symptoms such as weakness, tiredness, or even irregular heartbeats.
• Fresh fruits and vegetables are the best natural sources of potassium.
• When you eat potassium-rich foods, the amount of potassium in your blood increases. To maintain balance, your kidneys flush out the extra through urine, and some of it moves into your cells.
• While bananas are a good source, foods like beetroot, legumes, and sweet potatoes actually provide more potassium per serving.
• Eating a variety of plant-based foods daily ensures you get enough potassium. Fish is also a good animal-based source.

Which Foods are High in Potassium?

Potassium is a vital electrolyte and mineral that your body needs to support healthy muscle and nerve function, transport nutrients into your cells and maintain normal blood pressure. It’s considered a vital nutrient because your body can’t produce it.

Your recommended daily needs of potassium can be met with foods, such as:

Sweet Potatoes

Sweet potatoes are usually used as an alternative to white potatoes and are a nutritious way to support your potassium intake. Mashed sweet potato boasts 16% of the daily value in a one-cup serving.

They are also a good source of fibre and complex carbs, offer a small amount of protein, are low in fat, and are an excellent source of vitamin A (which is critical for vision).

For a filling and balanced meal, you can pair these delicious root vegetables with a protein source such as a little fat, some colourful or dark green vegetables, meat or beans.

Spinach

It is one of the most nutrient-dense vegetables. One cup of frozen spinach contains 12% of your daily requirement for potassium, and 3 cups of raw spinach contains about 11% of your daily requirement.

There are other nutrients as well, as the same serving of frozen spinach contains 127% of the daily value for vitamin A, 37% of magnesium, 58% for folate and 857% of vitamin K.

Watermelon

Watermelon is a delicious and large fruit with high water content. Just 2 wedges (about 1/8 of a melon) provide just under 14% of the daily value for potassium. The same serving also contains 2.2 grams of fibre, 0.8 grams of fat, 3.5 grams of protein and 44 grams of carbs. It is also a great source of vitamins A and C and magnesium.

Coconut Water

Coconut water is a hydrating drink. It contains key electrolytes that help draw water into your cells, so it is an excellent natural alternative to sports drinks. Its natural sugars also help replenish lost glycogen stores afterwards and also provide energy during exercise.

Just 1 cup of coconut water contains 13% of the daily value for potassium. It’s also a good source of manganese, sodium and magnesium.

After a sweaty workout, coconut water is very refreshing when served chilled with ice. The varieties with added sugar should be avoided.

Beans

Beans are a nutritious source of plant-based protein and complex carbs. Just one cup of white kidney beans contains twice as much potassium as a banana or a whopping 21% of your daily requirement.

Phytates, an antinutrient that may reduce your body’s mineral absorption, are present in black beans, so you can soak dried beans overnight to help decrease their phytate content, as this compound will leach into the water. Both black and white beans are versatile and easy to add to stews.

Legumes

Apart from beans, the legume family includes peanuts, soybeans, chickpeas and lentils, all of which are high in potassium. One cup of lentils contains 15% of your daily requirement for minerals, and the same amount of peanuts, soybeans and chickpeas contain 23%, 19% and 10% of your daily requirement respectively.

Certain legumes, such as chickpeas and lentils, contain phytates, so remember to soak them overnight to reduce their phytate content.

Tomato Paste

Tomato paste is made from cooked tomatoes that are seeded and peeled. 3 tablespoons contain more than 10% of the daily value. Tomato paste is also a good source of lycopene and vitamin C, a potent antioxidant with cancer-fighting properties.

This concentrated condiment adds flavour to all tomato-based dishes and sauces, but try to avoid products which have preservatives, additives or added sugars.

Potatoes

It is a starchy root vegetable that remains a staple food in numerous countries. One medium-boiled potato offers 12% of the daily value for potassium. There are many varieties of potatoes, and their potassium content might depend on the soil in which they are grown.

Dried Apricots

Dried apricots are normally pitted and have a long shelf life. Just half a cup provides 16% of the daily value of potassium. These fruits are also a good source of vitamins E and A and fibre. Dried apricots are used as a healthy snack for camping trips or hikes and are deliciously mixed into muesli.

Beetroot

1 cup of boiled beetroot gives you 11% of the daily value for potassium. This root vegetable contains nitrates, which your body converts to nitric oxide, which has been shown to support overall heart health and help blood vessels function.

Beetroot is also an excellent source of folate (a vitamin needed for DNA repair and synthesis) with 1 boiled cup providing 34% of the daily value. You can consume beetroot raw, pickled or boiled.

Pomegranate

Pomegranates are a many-seeded and extremely healthy fruit that vary in colour from purple to red. One whole fruit gives you 14% of the daily value of potassium. They are also packed with vitamins K and C, folate and have more proteins than most other fruits, at 4.7 grams per fruit.

Vegetable and Fruit Juices

Drinking vegetable and fruit juices is another easy way to increase your potassium intake. Citrus juices provide the most potassium. One cup of 100% orange juice provides about 10% of your daily recommended amount of potassium, and the same amount of grapefruit juice provides 9% of your daily recommended amount.

Potassium-rich fruit juices like pomegranates are also great alternatives. A 1-cup serving of pomegranate juice packs 11% of the daily value. Vegetable juices like one cup of carrot juice provide 15% of your daily requirement, and the same amount of tomato juice provides 10% of your daily requirement.

Salt Substitutes

Excess salt consumption might lead to high blood pressure, so salt substitutes were designed to help reduce sodium intake. These substitutes replace sodium with another element or mix of elements, usually potassium, to reduce heart disease without diminishing the taste or reducing the perceived salt intake.

Regular salt is 100% sodium chloride, however, salt substitutes might be composed of 10% magnesium sulphate, 25% potassium chloride and 65% sodium chloride. Others might have 100% potassium chloride, which packs 11% of the daily value in just 1 gram. Salt substitutes that are high in potassium should be avoided by people with liver or kidney disease.

Health Benefits of Potassium

Blood Pressure Control

Potassium helps balance the effects of sodium. High sodium intake raises blood pressure, but potassium relaxes blood vessel walls and helps the body excrete excess sodium through urine. This lowers the risk of hypertension.

Heart Health

Adequate potassium intake is linked with a reduced risk of stroke and other cardiovascular diseases. By stabilising heartbeat and supporting proper circulation, potassium directly contributes to heart protection.

Fluid Balance

Potassium helps regulate fluid levels inside and outside cells, ensuring proper hydration and nutrient transport. This balance is essential for energy production and cell function.

Bone Health

High-potassium diets may help reduce calcium loss from bones, improving bone mineral density and lowering the risk of osteoporosis.

Kidney Stone Prevention

Potassium reduces calcium excretion in urine, which helps prevent calcium-based kidney stones from forming.

Muscle Contraction & Nerve Signals

Potassium supports the transmission of electrical impulses in nerves and muscles, including the heartbeat. Deficiency or excess can disrupt these signals, leading to cramps, weakness, or irregular heartbeats.

Consequences of Potassium Imbalance

Hypokalemia (Low Potassium)

Symptoms: Weakness, fatigue, muscle cramps, constipation, irregular heartbeats.

Causes: Prolonged vomiting, diarrhoea, excessive sweating, use of diuretics, or poor dietary intake.

When to seek help: If you experience heart palpitations, severe weakness, or paralysis, consult a doctor immediately.

Hyperkalemia (High Potassium)

Symptoms: Numbness, tingling, muscle weakness, irregular heartbeat, nausea, or vomiting.

Causes: Kidney disease, certain blood pressure medications, dehydration, or excessive potassium supplements.

Why it matters: Unlike low potassium, high potassium can be life-threatening if untreated. Healthy kidneys usually excrete excess potassium, but those with kidney problems need close monitoring.
