Potassium is an essential mineral that is needed by all tissues in the body. It is naturally found in many foods and is also available as a supplement. Potassium helps regulate critical body functions, such as nerve and muscle function, and a potassium-rich diet is linked to numerous health benefits. For example, it can lower blood pressure and reduce the risk of cardiovascular problems. To increase your potassium intake, you can consume potassium-rich foods such as bananas, oranges, soybeans, lentils, salmon, and yogurt.

What You'll Learn
Eat potassium-rich fruits and vegetables
Eating plenty of fruits and vegetables is a great way to boost the potassium in your diet. Potassium is a mineral that is essential for all of the body's functions, helping your nerves, muscles, and heart to work properly. It also helps to move nutrients and waste around your cells.
Fruits that are rich in potassium include bananas, oranges, cantaloupes, honeydew, apricots, grapefruit, and prunes, raisins, and dates (when it comes to dried fruit). A medium banana, for example, contains 422 milligrams of potassium. Other fruits and vegetables that are good sources of potassium include tomatoes and tomato products, such as tomato paste and tomato puree. A quarter-cup of tomato paste contains 670 milligrams of potassium, while a half-cup of tomato puree has 560 milligrams. A medium fresh tomato has about 290 milligrams.
You can also get potassium from legumes, with one cup of cooked soybeans providing nearly 890 milligrams of potassium, and lentils and kidney beans containing about 730 milligrams and 600 milligrams respectively for the same serving. A cup of cooked squash has 640 milligrams of potassium, which is about 15% of your daily requirement.
Fruits and vegetables rich in potassium may also have a positive impact on bone health. Observational studies have found that a high potassium intake from these food groups is associated with higher bone density.

Choose potassium-rich legumes and meat
Consuming a diet rich in potassium is essential for normal cell function, helping your nerves, muscles, and heart to function properly. The recommended daily intake of potassium for adults is 4,700 milligrams. However, most people do not meet this goal. To boost your potassium levels, include a variety of potassium-rich legumes and meat in your diet.
Legumes, such as beans, lentils, and peas, are excellent sources of potassium. For instance, a cup of cooked soybeans provides about 890 milligrams of potassium, which is approximately 18% of the recommended daily value. Similarly, lentils offer about 730 milligrams of potassium per cup, while kidney beans contain around 600 milligrams in the same serving size. These legumes can be easily incorporated into various dishes, such as soups, stews, salads, and breads.
In addition to legumes, meat can also contribute to your potassium intake. Chicken breast, in particular, stands out as a good source, providing 332 milligrams of potassium per 3-ounce serving. If you prefer other types of meat, beef and turkey breast are also decent sources, containing 315 milligrams and 212 milligrams of potassium, respectively, in the same serving size. Including these meats in your meals can help boost your potassium intake.
For those who do not consume meat, fish is an excellent alternative. Fatty fish like salmon provide 326 milligrams of potassium per 3-ounce serving and are also rich in heart-healthy omega-3 fatty acids. Canned tuna is another option, offering 153 milligrams of potassium in the same serving size. By including these fish options in your diet, you can effectively increase your potassium intake while also benefiting from their additional nutritional qualities.

Consume dairy products with high potassium
Dairy products are a good source of potassium. Milk and yoghurt, in particular, are known to contain good amounts of potassium. For instance, one cup of reduced-fat milk contains 366 milligrams of potassium, while yoghurt has slightly more for the same serving with 440 milligrams.
If you are lactose intolerant or concerned about the saturated fat content in whole milk, opt for low-fat or non-fat milk and yoghurt products. These options still contain a good amount of potassium while helping you avoid the unpleasant side effects of lactose intolerance and the negative health impact of saturated fats.
If you are looking for a dairy product with an even higher potassium content, consider Gjetost cheese. In 100 grams of cheese, Gjetost contains 1409 mg of potassium, which is almost a third of the daily recommended amount. However, it is important to note that Gjetost also has a high sodium content, with 600 mg of sodium. If you prefer lower sodium options, opt for low or no-sodium varieties of Swiss, Cheddar, Colby, American, and Cottage Cheese. These cheeses have a favourable ratio of potassium to sodium but contain lower amounts of potassium, usually less than 100 mg in a 3.5 oz serving.
In addition to milk, yoghurt, and cheese, remember that dairy products also include creamers. Adding milk or creamer to your tea or coffee can significantly increase the potassium content of your drink.

Use salt substitutes with potassium
Salt substitutes are a great way to add potassium to your diet. They have been around for decades and are a healthy alternative to regular salt. Salt substitutes that contain potassium can help reduce sodium intake and increase potassium intake. Potassium is a mineral that helps lower blood pressure and reduce the risk of cardiovascular problems.
However, it is important to note that some people should avoid salt substitutes with potassium. While potassium has many health benefits, it can also raise blood potassium levels to dangerous levels in people with certain medical conditions. For example, people with kidney disease, heart disease, liver disease, or diabetes may be at risk of hyperkalaemia if they consume too much potassium. Similarly, those taking certain blood pressure-lowering medications, such as ACE inhibitors or potassium-sparing diuretics, should be cautious about using salt substitutes with potassium.
If you are considering using a salt substitute, it is important to consult your doctor or healthcare team first. They can advise you on whether it is safe for you to use these products and recommend alternatives if necessary. It is also crucial to read the product information on salt substitutes carefully, as some may not be suitable for those with certain medical conditions or dietary restrictions.
Overall, salt substitutes with potassium can be a healthy way to add more potassium to your diet and reduce your sodium intake. However, it is important to be aware of any potential risks and consult a healthcare professional before making any changes to your diet.

Take potassium supplements (with caution)
While potassium is found naturally in many foods, it is also available as a supplement. However, it is important to exercise caution when taking potassium supplements. Potassium is sometimes referred to as an electrolyte because it carries a small electrical charge that activates various cell and nerve functions. It is needed by all tissues in the body and helps the nerves, muscles, and heart to function properly.
The recommended daily intake of potassium for adults is 4,700 milligrams. However, most people do not meet this goal through their diet alone. If you are considering taking potassium supplements, it is important to speak to your doctor first. This is especially important if you have kidney disease or take certain medications, as your potassium levels may already be too high. Too much potassium can be dangerous for people with kidney problems because their kidneys cannot effectively eliminate excess potassium from the body. This can lead to a condition called hyperkalemia, which can cause irregular heartbeat or a heart attack.
Even if you do not have kidney disease, taking potassium supplements without medical advice can be harmful. Your doctor may advise you to get your potassium from dietary sources instead, as foods high in potassium are usually also high in other nutrients and low in sodium. This balance contributes to the health-boosting effects of potassium.
If your doctor does recommend potassium supplements, be sure to follow their instructions carefully. Do not exceed the recommended dosage, and be mindful of any side effects or interactions with other medications you may be taking. It is also important to note that salt substitutes are sometimes made from potassium chloride, which can be dangerous for people with kidney or liver disease. Therefore, it is always best to consult a healthcare professional before taking any form of potassium supplement.
