10 High Potassium Foods to Balance Your Electrolytes

Ultimate Guide to High Potassium Foods (> 300 mg) For Health and Longevity

You might die without it. Why?

Potassium is a crucial electrolyte to your well-being and longevity. There are countless delicious sources with way more than a banana. 

This article will list foods that are high in this important electrolyte. Simple as that.

Let me tell you why it is so important. It is the third most common mineral in your body. Fun fact right?

Potassium helps to regulate fluid balance, nerve signals and muscle contractions. It does this by interacting with salt -- the two work together to keep your minerals in homeostasis.

Before we get started, I want to mention that Chicken Bone Broth is among the highest potassium sources on the planet. Shocker right? It is the easiest and most delicious way to get more into your diet.

What are the health benefits of consuming foods high in potassium?

There are many powerful health benefits of high-potassium diets. For example, it can lower blood pressure and water retention, protect against stroke and prevent osteoporosis and kidney stones (1).

The big issue is that most adults in Canada and the USA get half of the recommended daily intake (2).

Most experts recommend targets of 3500-4700 mg per day. What’s interesting is that there are no additional pros to getting more, except under extreme conditions. 

Athletes or those who perform long, strenuous exercise will lose more potassium from sweat and may need some more.

High risk groups like those at risk for osteoporosis, kidney stones, stroke or high blood pressure may benefit from more than the recommended guidelines.

What are the signs and symptoms of potassium deficiency?

The symptoms of potassium deficiency are similar to those of sodium or salt deficiency, including fatigue and weakness.

The recommended daily intake is 4,700 milligrams a day, but the average American consumes only 2,600 milligrams a day.

It's an electrolyte that helps to regulate the amount of fluid and moves nutrients into cells, so a deficiency can lead to muscle weakness and heart problems.

How does potassium help balance electrolytes in the body?

Your electrolyte balance is directly related to your potassium intake. The amount of fluid in your body is regulated by the concentration of electrolytes.

It regulates fluid inside your cells, while sodium / salt is in charge of the water outside of your cells. 

There should be an equal balance of electrolytes both inside and outside the cells within your body. 

When they are unbalanced, fluid will move from one area to another to try to hit your electrolyte targets. Your cells will either swell up or shrink, leading to dehydration which can affect your heart and kidneys (3).

Key takeaway:

Eating things that contain potassium is important to keep you hydrated and regulate fluid balance.

Dietary Potassium Regulates Your Nervous System

Eating enough potassium also helps you maintain healthy nerve function. How? 

It is needed to generate nerve impulses inside your body. 

What are nerve impulses? They basically do everything: from regulating your pulse to reflexes and muscle contractions (4). 

Potassium Intake's Important Role in Heart Contractions and Muscle

Low potassium directly affects your muscles ability to work properly, making them weak and useless. 

It's also crucial to heart function. Overdo it or too little will cause an irregular beat (5). 

If it doesn't work properly then bad things happen. Eventually you won’t be able to effectively pump blood to your brain and organs (6). 

How can I know if I'm getting enough potassium in my diet?

You know if you're getting enough potassium if your urine is clear or pale yellow. If it's dark, you're not getting enough and your body needs more. In this case, eat more natural sources like fruit and vegetables to hit your targets and get your urine clear.

Potassium Health Benefits 

Potassium has many health benefits that protect you from stroke, osteoporosis, high blood pressure, kidney stones and bloating from water retention. Heres more information on each of these in detail.

Stroke

Studies show that a diet full of potassium is shown to reduce the likelihood of stroke and heart disease (7). 

Osteoporosis

Adequate targets in your diet helps your bones stay strong by reducing the calcium your body loses in urine (8).

Blood Pressure

A potassium-rich diet might lower blood pressure by assisting in the removal of excess sodium in your body (9).

Kidney Stones / Disease

Kidney stones are clumps of material, mainly calcium, that are concentrated in urine. Studies show that potassium lowers calcium in your urine to help fight kidney disease or stones (10). 

Water Retention

You can decrease your water retention by consuming large amounts of it. This will make you pee which reduces your sodium concentrations according to studies (11).

Food Sources of Potassium

1. Beet Greens or Chard

1 cup, cooked: 1309 mg - 28% DV

The green leaves of the beetroot plant are edible and have more potent nutrients than the actual beet. 

Greens are full of vitamins like Vitamin C to keep your immune system healthy and strong. The naturally occurring Vitamin C also assists in skin, bone, hair and teeth.

Greens also help with eye and vision because of the high amounts of Vitamin A. Lastly, they are full of fibre, Vitamin K2, iron, copper and manganese. 

I roast them in the oven for 5-10 minutes with some oil and salt, then add to whatever I am cooking. They are delicious! 

You’ll find similar potassium targets in vegetables like swiss chard.

2. Avocado 

1 whole portion: 975mg - 21% DV

Certainly having a moment, and for good reason. Avocados are nutrient dense, delicious and full of vitamins, fibre and monounsaturated fats (the ‘good’ kind). 

Research shows that those who eat avocados (toast anyone?) tend to have better diets with higher nutrient intake (thanks, captain obvious) but they’re also at a lower risk for metabolic syndrome (12). They are the most potassium rich fruits you'll find. Yes it's a fruit.

3. Acorn Squash

1 cup, cooked: 896mg - 19% DV

This is a cool looking vegetable with naturally occurring antioxidants and electrolytes. As a result of carotenoid antioxidants, it promotes overall wellness and may protect against heart disease, cancer and type 2 diabetes (13).

4. Wild-Caught Salmon 

4 oz portion: 712mg - 16% DV

Who would have thought a fish dinner had electrolytes? Salmon is also full of omega 3 fatty acids like EPA and DHA, which are important for just about everything from inflammation to brain development. 

It's also has high quality protein, Vitamin D, selenium and other fats that are beneficial for skin health too.

The great thing is that you get so much of it in small fish portions that you don't need to eat much to get the nutrition. Tuna, halibut, snapper filets or clams have some but not nearly as much.

5. White Potatoes (With Skin)

1 medium: 620mg - 14% DV

These guys get a bad rep due to the hype around sweet potatoes and yams. However, good ol’ fashioned white potatoes with skins on are a good source of potassium, magnesium, B6, fibre and antioxidants.

They are cost effective and easy to cook and eat. Great source of carbohydrates to fuel your needs.

6. Chicken Bone broth 

1 mug (375ml): 600mg - 13% DV

Chicken bone broth is among the best potassium sources, but it also contains hydration from phosphorus, chloride and sodium.

The slow simmer process and types of bones used is key to extracting the electrolytes into the broth. Bluebird Provisions makes the one with the highest at 400 mg per serving you'll find. Browse our website for more info.

Bone broth has 26 times more potassium than collagen powder and 1.5 times that of a banana.

7. Coconut Water

1 cup: 600mg - 13% DV

Another liquid with lots of it is coconut water. Be careful with drinking it as most of the over the counter versions are full of sugar and excess calories.

Check the nutrition label to ensure there are limited added ingredients. That being said, it is a great solution if you are low on electrolytes and hydration. 

8. Mushrooms (White or Portobello)

1 cup, cooked: 555mg - 12% DV

More powerful potassium vegetables! White mushrooms have a variety of vitamins and minerals offering many health benefits.

These include cholesterol-controlling effects, cancer-fighting properties and gut health (14). Mushrooms are also high in B vitamins, low in calories and relatively high in protein. 

9. Large White Beans or Lima Beans

½ cup, cooked: 502mg - 10% DV

White beans are one of the best foods for potassium. They are also full of fiber, protein and vitamin B6.

Kidney / navy / adzuki beans or lentils have some as well, but not as much. Fiber is important to your overall health and wellness as it helps you control blood sugar and protects you from chronic diseases. 

10. Vegetable Stock / Juices

1 mug (350ml): 450mg - 9% DV

Properly made stock from potassium rich vegetables is the perfect complement to your cooking. It also has all your electrolytes in perfect balance including: phosphorus, magnesium, chloride, calcium and sodium.

Vegetable juice and stock products with superfoods like reishi and shiitake mushrooms, and seaweed give you more benefits.

The Best Fruits High in Potassium

Fruits high in potassium include bananas, plantains, oranges, cantaloupe, honeydew, apricots, tomatoes and grapefruit.

I left most of these off of the list above because they have less mg per serving. But these fruits are great for maintaining hydration as well.

Many people ask about orange or pomegranate juice: these has it but are usually full of sugar, so I do not recommend them.

How can I add more potassium-rich foods into my diet?

You can add more potassium-rich foods (vegetables) to your diet by drinking chicken bone broth, eating tomatoes in salad, fish, potatoes and drinking coconut beverages.

Bone broth is the number one convenient source of potassium with up to 400mg per serving if you use the one from Bluebird Provisions.

Do I Need To Take Potassium Supplements?

You do not need to take a potassium supplement in most cases. Why? Most countries limit the dosage of supplements to 100mg per serving or 2% of your daily intake. 

This is because supplements are dangerous in high amounts to gut and heart health (15). You are better off getting it from whole sources.

The Bottom Line
