Top 10 Foods Highest In Electrolytes: Eat These To Prevent Imbalances

top 10 foods high in electrolytes

Electrolytes are substances found in the body that affect its electrical balance. Electrolyte imbalances can lead to life-threatening health conditions, especially for people with chronic kidney disease or heart failure. Fortunately, for those of us without any underlying conditions, eating foods high in electrolytes is an easy way to maintain a healthy balance of these essential elements. In this article, we’ll cover  the top 10 foods highest in electrolytes, along with their benefits for promoting good health.


Why Are Electrolytes Important?

An electrolyte is a substance that separates ions when dissolved in water that carries current in solution. Your brain, heart and muscles function because of electrolytes.

Ions are minerals that carry either a positive or negative charge which enables them to conduct electricity when dissolved in water. The most common electrolytes include:

  • Sodium (Na+)
  • Potassium (K+)
  • Calcium (Ca2+)
  • Chloride (Cl-)
  • Bicarbonate(HCO3-) 
  • Magnesium (Mg2+)
  • Phosphate (PO4 3-). 

Electrolyte levels are mainly regulated by the kidneys. They keep an optimal balance between the ions for homeostasis. Sodium is one of the primary electrolytes that causes many health problems if levels get too high or low (12).

The good thing is that your body can easily handle changing levels of electrolytes because it has mechanisms in place to keep them within a safe range. If those mechanisms aren’t working correctly due to a chronic illness or dehydration, sodium can build up in your interstitial fluid, causing water retention. Excessive water retention leads to swelling of hands, face and legs which then becomes oedema (22).

Electrolytes help regulate the amount of water and other fluids in and around cells, as well as maintain the normal function of nerves and muscles. They also play a role in proper digestion and muscle contractions, including those that occur during exercise or periods of intense activity (10).

This herb is packed with nutrients like magnesium, manganese and potassium. It’s also a great source of calcium as well as vitamins A and C.

What Causes Electrolyte Imbalances?


The most common cause of electrolyte imbalances is dehydration (6). If you don’t drink enough water, your levels of sodium and other minerals can drop or rise to dangerous or even fatal levels. If you feel thirsty, you’re already dehydrated. Be sure to drink plenty of water throughout the day, and drink extra water when it is hot and when you exercise. You can lose both water and electrolytes through sweat, so if you are participating in an activity that causes you to sweat a lot, you may need to replace both water and electrolytes using either a commercially prepared or homemade oral rehydration solution.

Kidney Function

Another common cause of electrolyte imbalances is impaired kidney function. If your kidneys aren’t working properly due to an acute or chronic condition, you may have trouble excreting excess sodium, potassium, phosphate or other minerals (6).

Eating Disorders

Eating disorders like bulimia and anorexia can lead to problems with electrolyte balance as well. When these conditions involve vomiting after eating or laxative abuse, the body loses important electrolytes and minerals that are needed for cellular structure and function. In the case of anorexia or chronic undereating, the body doesn’t get in enough of those electrolytes in the first place, which often leads to imbalances.

As you get older, your body might become less efficient at maintaining electrolytes in the blood. This means that elderly people should be especially careful about their intake of salt as well as foods high in sodium (9).


People with diabetes can be prone to electrolyte imbalances due to a variety of factors associated with their diabetes, such as impaired kidney function, malabsorption, acid-base disorders, and medication regimens (5). If you have diabetes, talk to your health care provider about signs to look out for and how to address electrolyte imbalances if they occur.


There are a number of medications that can cause problems with electrolytes. Kidney problems, heart failure and other conditions may require people to take diuretics, which make the kidneys release more water into the urine. Those who use these medications should regulate their intake of salt as well as potassium-rich foods like bananas and keep an open dialogue with their health care providers. Laxatives and other medications can cause problems with electrolyte balance as well (7).

What Are The Signs Of Electrolyte Imbalance?

When the level of electrolytes in your body is too low or high, it causes symptoms such as:

Fatigue And Weakness

Common symptoms of low sodium levels are fatigue and weakness (12). When your body can’t produce enough energy due to an imbalance of electrolytes, it will try to preserve its resources by slowing down metabolism which then makes you feel fatigued all day long. 

Muscle Cramps Or Spasms

Electrolytes also play a vital role in muscle contraction and nerve impulses. This is why having optimal levels maintains strength and flexibility. If there’s a lack of electrolytes, your muscles may either cramp or spasm (12).  

Heart Palpitations And Irregular Heartbeat

When levels of potassium, calcium and magnesium decline rapidly it can lead to heart palpitations or irregular heartbeat which then causes shortness of breath and fainting. These symptoms are very similar to a recent myocardial infarction (heart attack). However, if you feel them after exercising for more than an hour they’re likely caused by electrolyte imbalance (12). This can be serious and requires medical attention.


Seizures And Fainting

Rapid shifts in water and/or sodium levels increase the risk for seizures or loss of consciousness (fainting). Usually, these serious symptoms appear when there’s a rapid decline or increase of sodium levels (12). If you have a seizure or loss of consciousness, medical attention is required.

Nausea And Vomiting

When you vomit, you lose both fluid and electrolytes. The lack of these nutrients causes an imbalance that makes you feel dizzy, weak and tired throughout the day (8).

Diarrhoea Or Constipation

Water and fluid are absorbed in the digestive tract. When things move too quickly, your body doesn’t get a chance to absorb them. In some cases, diarrhea even pulls fluid and electrolytes from the bloodstream back into the GI tract and they are then lost through the stool  (8). Constipation, on the other hand, can be a sign of dehydration, which is a major contributor to electrolyte imbalance.

Heart Palpitations

If there’s a sudden decline in any level of calcium, potassium or magnesium, it can lead to heart palpitations which is one of the most common symptoms. Also, this is what happens when electrolytes are regulated too rapidly or they’re depleted quickly (12). If you experience heart palpitations, discuss it with your healthcare provider as you may need to be evaluated.

Electrolytes are able to regulate fluid balance in your brain which then reduces headaches. However, if there’s a rapid rise or decline the headache might cause the vision to blur and become sensitive to light (12).

Changes In Blood Sugar Levels

When levels of magnesium drop it affects insulin production which controls blood sugar levels. This increase or decrease can cause fluctuating energy levels, irritability, nausea or fatigue throughout the day (12).

Memory Loss

Low levels of potassium might trigger memory loss due to neurotransmitters that govern cognitive functions such as decision-making, memory retention and learning abilities (26).

How To Keep Your Electrolytes In Balance

The importance of electrolytes in the human body cannot be overemphasized. A number of common health problems are directly related to electrolyte imbalances. Additionally, the endocrine system relies on proper electrolyte balance for optimal function. Here are a few things you can do to ensure consistent balance:

Be Well-Hydrated

Drink at least six glasses of water per day. Water helps maintain proper hydration and prevents electrolyte imbalances by providing adequate minerals needed for reactions involving enzymes. You need to drink extra water if it is hot out or you are exercising. If you aren’t sure how much to drink, you can monitor your urine to gauge your hydration status – it should be pale yellow or clear, not dark and concentrated.

Don’t Drink Too Much Water

Drinking too much water in a short period of time may also cause electrolyte imbalances. This condition, known as hyponatremia, is caused by an overabundance of water relative to the amount of salt in the blood. Too much fluid dilutes essential minerals and can lead to dangerous or even fatal consequences if countermeasures are not taken (17). This is most likely to happen in a situation where you are losing both water and electrolytes (due to heavy sweating, vomiting, or diarrhea) and only replacing the water, but not the electrolytes. If you are losing water and electrolytes, it’s best to drink an oral rehydration solution instead of just plain water.

Eat Foods Rich In Electrolytes

It’s best to get your minerals from food whenever possible. Electrolytes found in whole foods have been paired with cofactors that help them function properly within the body.

Increase your intake of potassium-rich fruits, vegetables, beans, seeds or nuts daily (23). These foods are also high in B vitamins—particularly folic acid—and vitamin C which are essential cofactors responsible for protein metabolism and energy production.

Bananas are an excellent source of potassium as well as magnesium, a mineral that helps regulate calcium levels in the body. Vitamin B6 is necessary to convert tryptophan into niacin (vitamin B3) which enhances metabolic function and supports healthy bowel elimination (1).

Cut Back On Caffeine

Reduce sources of caffeine intake in your diet. Caffeine causes loss of water and important minerals through increased urination, therefore, affecting electrolyte concentrations (2).

Cut Back On Alcohol

Reduce sources of alcohol intake in your diet. Alcohol causes loss of water and essential minerals through increased urination resulting in altered electrolyte concentrations (24).

Cut Back On Salt

Avoid salty foods such as salted popcorn, chips, sausage, ham, corned beef, bacon and the like which are high in sodium chloride (salt). When combined with high carbohydrate snacks or beverages—like sugar or caffeine-containing soft drinks—this can result in an accelerated loss of potassium that may induce hypokalemia which can lead to muscle weakness/cramps and slow reflexes (16).

Don’t Overuse Diuretics Or Laxatives

Many over-the-counter medications, including diuretics and laxatives, can induce electrolyte imbalances. Consult  your healthcare professional before using any medications to determine safe dosages and associated side effects.

Herbal supplements are not regulated by the FDA which means that it is possible they may interact with prescription medication or cause adverse reactions when taken together. It’s best to avoid any herbal supplements until you’ve talked with your healthcare provider.

Don’t Do Strenuous Exercise In Hot Weather

When you are dehydrated, your blood becomes more concentrated which increases the risk of developing hyponatremia (17). Strenuous exercise in hot weather can cause body fluid loss through perspiration. Ensure that you drink plenty of fluids before and after strenuous physical activity to prevent electrolyte imbalances due to dehydration or excessive salt loss. 

Be Aware Of Certain Medical Conditions

A number of medical conditions may increase your chances of developing an electrolyte imbalance. These conditions include: diabetes, Addison’s disease, kidney disease, liver cirrhosis, Crohn’s disease or ulcerative colitis, certain endocrine disorders, wasting syndromes, malnutrition, metabolic alkalosis and certain cancers (8).

Consider Electrolyte Supplements

These supplements can help replenish essential minerals during times of increased loss due to vomiting, diarrhea, excessive perspiration or malabsorption. Electrolytes can also assist in restoring mineral balance following strenuous exercise (18). You can purchase supplements or commercially prepared electrolyte solutions, or make your own oral rehydration solution using a recipe based on the WHO’s recommended concentrations.

If you’ve been diagnosed with a specific electrolyte imbalance or medical condition, seek advice from your healthcare provider to determine whether using electrolytes supplements is right for you. 

The Bottom Line

Electrolytes are minerals that carry an electrical charge. They’re vital for health and survival. If you are experiencing any symptoms of electrolyte imbalance, it’s important to consult your healthcare provider for advice on how to keep your electrolytes in balance.

I've struggled to maintain programs…

I've struggled to maintain programs before, but somehow I've been able to stick with this. I enjoy the workouts and have made healthy changes to my diet with the challenges. Its nice for something to really have stuck and worked. I did the sugar free challenge and it's really changed how I relate to the signals my body is giving me about the food I'm eating.

Our Journey

This has been an awesome journey for my wife and I. Not only are we losing weight , but we are living a new life style. Our eating habits have been reformed by following the meal plan and our bodies have become stronger by simply doing the ten minute, sometimes twenty minute workouts. It really has been easy and convenient to transition into a healthier routine and has truly re energized our lives moving forward into the future.

It Works! This program is working for me!

lynne R.
This program is working for me! After a little over a month, I have lost 10 pounds. Slow, but steady. Guided exercises are done daily and there is an option to do other routines beside the one chosen for the day. It is very helpful having the recipes for all meals plus a snack. Would like if we could know the ingredients the day before. Makes preparing alot easier. I like the fact that alternative foods are suggested in case you can't eat(or don't like) the recipes listed. This is a very good program. Stick to it and YOU will see results. I have!
