food sources of potassium

Potassium is an essential mineral that our bodies require for hydration and proper cellular function. 

It's the third most abundant mineral in the body and works in a balance with sodium to regulate blood pressure and fluid transfer in/out of cells. 

Potassium is also critical for the proper function of many vital organs in your body including the heart, brain, kidneys, and more. 

Unfortunately, researches estimate that only 3% of Americans meet their daily recommended intake of potassium. This is likely due to poor dietary choices and not consuming enough potassium rich foods. (1)

Intaking adequate amounts of potassium-rich foods is essential for optimal health. 

This article will cover the best food sources of potassium, many of which may surprise you!

Wild salmon is an amazing source of healthy omega 3 fats, high-quality protein, and an assortment of micronutrients! 

It's not typically viewed as  high potassium food, but it actually contains a ton of potassium. (6)

Just be sure to avoid farmed-raised salmon which is far inferior to wild-caught. 

I believe wild salmon to be one of the best animal foods you can eat!

In addition to the top 5 foods listed above, here are some other food sources of potassium that are still great:

  • Pomegranate - 1 whole: 667 milligrams (19 percent DV)
  • Coconut Water - 1 cup: 600 milligrams (17 percent DV)
  • White Beans - ½ cup: 502 mg (15 percent DV)
  • Yogurt and Claims are also good potassium foods 

Are Bananas High In Potassium ? 

So many people have been mislead to believe that bananas are the best food source of potassium.

While they do contain some potassium, this is far from the truth. All 5 foods listed above are superior sources and provide more benefit to your overall health than bananas. 

I can't tell you how many people I've worked with that, during our initial consultation, express that their "healthy breakfast" consists of one or two bananas and a cup of coffee. 

Consuming solely a banana for breakfast will spike your blood sugar, while not supplying your body with the health fatty acids and essential amino acids it really needs. 

The high sugar content in the banana can also cause low energy and sugar cravings throughout the day. 

Additionally, the vast majority of store bought bananas have been hybridized to be bigger and sweeter (aka more sugar) than the heirloom varieties we used to consume in the past. 

They are typically picked pre maturely off the vine before the fruit has a chance to receive all the valuable nutrients from the plant. Then they are shipped far distances to then be flash "ripened" with ethylene gas. 

I am not saying bananas are the devil and should never be consume, but just explaining they aren't the healthy food many people are taught to eat daily. They do have a decent amount of potassium. 

If you do eat a banana, do so along side other healthy fats and high-quality protein

Harmful Effects of Low Potassium 

Since potassium and sodium act in conjunction with each other in your body, getting too much of one or the other can lead to issues. 

This is common in the Standard American Diet since folks are eating processed foods that contain a lot of salt, and not enough of the potassium rich foods listed above. 

Lack of adequate potassium intake can lead to: 

  • Constipation 
  • Weight gain 
  • Fatigue and low energy levels 
  • Heart problems 
  • Blood pressure issues 
  • Muscle and abdominal cramping 
  • Poor mood 
  • And much more 

For any athletes or individuals who are sweating regularly, getting enough potassium and other electrolytes is especially important for proper hydration status!
