High Potassium Foods - What They Are & Why You Should Eat Them

Updated on March 8, 2011

Why Eat Potassium-Rich Foods?

Potassium is a mineral key to the efficient working of the human body. It is vital to neuron function in your brain and nerves, aiding in your body's communication with itself. It is also necessary for muscle contraction, and in balancing electrolytes and avoiding dehydration. For these reasons, it's especially important for athletes and those with active lifestyles, but even the average couch potato can benefit from a diet high in potassium.

In 2004, the Institute of Medicine recommended an intake of 4000 milligrams of potassium per day, but the average American eats less than half of that on a daily basis. A low-protein diet can result in muscle weakness, slowed digestion, and weaker reflexes. While severe protein deficiency is rare, it is very serious when it happens, manifesting in labored breathing and irregular heartbeat.

Most people would benefit from an increased intake of potassium, but there are exceptions. Since the kidneys control the excretion of potassium, people suffering from kidney diseases must observe a low-postassium diet for health reasons. For these individuals, potassium buildup in the blood of these individuals can prove fatal.


Foods High in Potassium

While meat and fish and most fruits and vegetables contain potassium, some sources are better than others. A list of high potassium foods is as follows:


  • Papaya
  • Prune
  • Honeydew melon
  • Canteloupe
  • Banana
  • Apricot
  • Kiwi
  • Mango
  • Orange
  • Raisins
  • All dried fruit




  • Avocado
  • Tomato
  • Potato
  • Sweet potato
  • Winter squash
  • Pumpkin
  • Asparagus
  • Spinach
  • Mushroom
  • Brussel sprouts
  • Artichoke
  • Beets
  • Carrots


  • Lima beans
  • Pinto beans
  • Lentils
  • Soy
  • Salmon
  • Beef
  • Dark-meat poultry
  • Peanuts
  • Sunflower seeds

Note that different forms of these foods can be good sources of potassium as well: for example, orange juice, soy milk, and peanut butter. Of course, you want to eat the leanest, least-processed version of each high-potassium food that you can.

In the end, however, it's more important that you get your potassium than how you get it. And it's important that you get it from food, rather than supplements, which do not absorb as well as potassium from food sources does. For the sake of your heart health, for the sake of your muscles and cells and neurons, up your potassium. Your body will thank you.

      Does potassium have a bitter aftertaste? My chimpanzee Bow will not take antibiotics that are mixed with potassium. When he had strep throat, I had to tell the pharmacy to make sure that they used a sugary flavoring and no potassium, otherwise he wouldn't swallow it.

      Bananas are the obvious choice, but you give such a great example of so many other foods. Great hub. Thanks for sharing.

      Anyone who takes medication for high blood pressure should be aware that you can become dangerously low on potassium. Several years ago my postassium level wasn't being checked and I ended up having a heart attack. Now I make sure I get plenty of potassium in my diet. Very worthwhile hub!

      Thank you for this hub Maddie. My mother has had kidney surgery and will be coming to visit me next week. Whenever I ask her what foods she can eat, she basically says "nothing". She is on a very restricted diet and I am having a hard time trying to figure out what foods to get for her while she visits. Not much to choose from since the doctors have also told her to keep her protein to a minium as well. At least I know what not to buy. Thanks again Maddie, as always an excellent hub.

      I like potatoes and sweet potatoes, but I prefer light-colored meats (e.g. chicken) over dark meats.
