Potassium Sodium Ratios

author avatar Dr. Eric Berg 11/26/2023

Have you ever felt like a wind-up toy running out of steam despite eating well and getting enough rest? That's how I first knew something was off. My body was missing an essential piece in its health puzzle - potassium.

Potassium is no small player; it keeps our heart beating right and our muscles moving smoothly. Yet so many of us don't know the signs when this critical mineral starts to run low in our bodies.

Are you consuming enough bananas or maybe avocados? Could that nagging fatigue be more than sleep debt?

This post will unravel the mystery behind potassium deficiency symptoms for you. We'll dig into why we need it, what happens when we don't get enough, and even debunk some common misconceptions about assessing your levels accurately.

By sticking around till the end, you'll make some fantastic discoveries and gain insights that could be game-changers for you.

Understanding Potassium and Its Role in the Body

Potassium, a critical mineral for our body, is essential in various bodily functions. Men consume about 3,000 milligrams of potassium daily, while women take slightly more than 2,000 daily. But this is not enough.

The Recommended Daily Allowance (RDA) for potassium is a whopping 4,700 milligrams.

The Sodium-Potassium Pump and Energy Production

Every cell within us houses the sodium-potassium pump that uses these minerals to create energy and facilitate movement. It's like having billions of tiny power plants inside us.

In contrast with modern consumption levels of potassium, though, our prehistoric ancestors had diets rich in it.

They consumed between 7,000 and 15,000 milligrams daily – quite a bit compared to today's standards. Imagine if we could go back to eating such healthy amounts now.

We'll explore how current dietary habits affect our intake level next time. Stay tuned.

The Impact of Diet on Potassium Levels

What we eat significantly affects our body's potassium levels. But how? It's all about the equilibrium between sodium and potassium.

The Prehistoric Diet vs Modern Consumption

Our prehistoric ancestors consumed high-potassium diets that maintained a healthy sodium-potassium ratio. Believe it or not, the prehistoric diet consisted of an average intake between 7K and 15K milligrams of potassium per day. Today's diet looks quite different, though.

In contrast to the past, modern Americans have an imbalanced sodium-potassium ratio of around 1:4 due to the inadequate consumption of potassium-rich foods.

Instead of munching on bananas or sweet potatoes rich in this essential mineral, most people opt for processed food.

Foods That Deplete Potassium Levels

Pesky culprits like refined carbohydrates and sugars have been linked with lower potassium levels. Stress doesn't help either - it can deplete your body’s reserves. Think about that next time you reach for a sugary soda.

Health Risks Associated with Potassium Deficiency

Your body is like a finely tuned machine. But what happens when an essential cog, potassium, isn't at the proper level? Let's dig into that.

Potassium Deficiency and Cardiovascular Health

If you've ever had your heart race after a good fright or during intense exercise, imagine that feeling but all the time. Not so much fun anymore. Insufficient potassium can lead to elevated blood pressure & even a stroke.

The beat doesn't stop there either; deficiency in this mineral might cause cardiac hypertrophy—a fancy term for an enlarged heart.

The Role of Potassium in Blood Sugar Regulation

Imagine trying to get somewhere without directions—chaos, right? That's what it’s like for insulin without enough potassium—it struggles to regulate your blood sugar levels effectively.

Luckily, though, increasing your intake could help improve insulin resistance. It just shows that everything works better when it needs what it needs.

Assessing Potassium Levels Accurately

You might think a simple blood test could reveal your potassium levels, right? Well, not quite. Only about 2% of your body's total potassium reserves are found outside the cell.

Blood tests may not accurately represent the potassium in your body, as only a tiny portion is outside cells. They're trying to judge the size of an iceberg by looking at what's above water - it just doesn't work.

We need intracellular testing to get around this problem and accurately measure our body’s supply of this essential mineral. This method gets up close and personal with our cells where most (98%, remember?) of our stored potassium lives.

Research shows that relying on regular blood tests alone can miss out on identifying people with low levels but appear normal due to their minimal extracellular concentrations.

Factors That Increase the Need for Potassium

Your body's demand for potassium can rise in certain situations. Stress is a primary culprit. When you're under pressure, your body needs more energy, requiring additional potassium.

Injury or shock are other triggers. They cause cellular damage, increasing the need for this essential mineral in the repair process.

Surgery also raises your requirements because healing from surgical wounds demands extra nutrients like potassium. 

This information highlights why monitoring our dietary intake during such times is essential - something many might overlook amidst life's stressors.

Keto Friendly High in Potassium Food

In ketogenic diets, finding foods high in potassium that are also keto-friendly can be a bit challenging. However, some options exist to help you maintain your potassium levels while staying in ketosis.

Avocado, for example, is a fantastic choice as it is rich in healthy fats and packed with potassium. Spinach and other leafy greens can also be included in your keto diet to boost potassium intake.

These foods high in potassium play a vital role in maintaining proper muscle function, heart health, and overall electrolyte balance, making them valuable additions to your ketogenic lifestyle.


Who would have thought that a lack of potassium could cause such drastic consequences in our bodies? It's no longer a mystery now, right?

We've learned about the crucial role of potassium in energy production and maintaining heart health. And how modern diets can contribute to its lack?

Potassium Deficiency Symptoms are not always obvious. But knowing them is half the battle won.

The other half? Making sure we get enough from our diet or supplements if necessary, especially when under stress or after an injury.

Intracellular testing - it's essential for accurate assessment. So, let’s not rely solely on standard blood tests anymore!
