Salt is Life

Salt: The Most Essential Nutrient and Electrolyte in the World

Salt is life. It is woven into the fabric of our existence, our physiology, and even our history. Yet, for decades, we have been bombarded with the notion that salt is harmful, that it leads to hypertension, and that we should avoid it at all costs. I used to believe this too—until I read The Salt Fix by Dr. James DiNicolantonio, which challenged everything I thought I knew about salt. That book, along with my own research and experience as a fitness and nutrition expert, changed my perspective entirely.

Now, I want to set the record straight: Salt is not the enemy. In fact, it is one of the most crucial substances for human life, athletic performance, and overall well-being. Let’s dive deep into what salt is, why it is essential for life on earth, and why it needs to be a priority in your diet.

What Is Salt and Why Is It Essential?

Salt, scientifically known as sodium chloride (NaCl), is a compound that plays a foundational role in our bodies. It regulates fluid balance, supports nerve function, aids in muscle contractions, and is crucial for maintaining blood pressure. Every cell in your body relies on the presence of salt to function correctly.

When we eat salt, our bodies use the sodium component to facilitate electrical signals between nerve cells, maintain proper hydration, and regulate the body’s acid-base balance. Without adequate salt intake, our energy levels plummet, our mental clarity diminishes, and our athletic performance suffers.

The Medical Myths: Why Salt Was Demonized

For years, medical professionals and governmental dietary guidelines have warned us that salt intake leads to high blood pressure and heart disease. But is that really true?

Modern research suggests otherwise. While some individuals with salt-sensitive hypertension may need to moderate intake, for the vast majority of people, the real culprit behind heart disease and chronic inflammation isn’t salt—it’s sugar. Excess sugar consumption leads to insulin resistance, obesity, systemic inflammation, and arterial damage, which are far more concerning than salt when it comes to cardiovascular health.

Studies have shown that individuals who consume adequate salt, rather than excessively restricting it, have better metabolic function, improved insulin sensitivity, and reduced sugar cravings.

The Chronic Dehydration Epidemic

Most people today walk around in a state of chronic dehydration, not because they aren’t drinking enough water, but because they lack adequate electrolytes—especially salt. Drinking plain water without sufficient sodium can actually dilute essential minerals in the body, leading to symptoms like fatigue, headaches, muscle cramps, and brain fog.

This is especially true for athletes, who lose significant amounts of salt through sweat. Replenishing salt is vital to avoiding dehydration, maintaining performance, and preventing cramps. I always tell my clients: When you sweat, you lose salt, just like when you cry. That alone tells you how crucial it is to our bodies.

The Benefits of Proper Salt Intake

Adding the right amount of salt to your diet provides tremendous benefits:

• Improves Athletic Performance – Salt helps retain hydration and enhances muscle function.
• Supports Weight Loss – Adequate sodium levels help regulate metabolism and curb sugar cravings.
• Enhances Brain Function – Electrolytes like sodium are critical for nerve signaling and cognitive function.
• Boosts Energy Levels – Sodium supports adrenal function, preventing fatigue and burnout.
• Reduces Sugar Cravings – Salt helps balance blood sugar levels, reducing the body’s need for quick energy from processed sugar.

The Biblical and Historical Significance of Salt

Salt is deeply embedded in human history. The Bible references salt repeatedly, symbolizing purity, preservation, and covenant. Jesus himself said, “You are the salt of the earth” (Matthew 5:13), emphasizing its importance not just for physical sustenance, but for spiritual significance.

In ancient cultures, salt was so valuable that Roman soldiers were sometimes paid in salt—a practice that gave rise to the word salary. Wars have been fought over salt, and entire economies were built upon its trade.

Beyond its spiritual and economic significance, salt also played a crucial role in food preservation before refrigeration. By drawing moisture out of food, salt inhibits bacterial growth, making it a natural method of keeping food fresh. Our ancestors survived harsh conditions thanks to salt, and it continues to be a staple in traditional food preparation around the world.

The Best Salts to Use

Not all salt is created equal. While standard table salt is heavily processed and often contains anti-caking agents and additives, natural salts provide a much richer mineral profile.

Some of my favorite salts include:

• Sea Salt – Rich in trace minerals and harvested from evaporated seawater.
• Celtic Salt – Known for its grey color and high mineral content, sourced from coastal regions in France.
• Himalayan Pink Salt – Mined from ancient salt deposits in Pakistan, packed with minerals.
• Red Hawaiian Salt – Contains volcanic clay, giving it a unique flavor and nutrient profile.
• Black Lava Salt – Infused with activated charcoal for added detoxification benefits.

I’ve had the privilege of receiving salts from clients all over the world—Turkey, India, Paris, Hawaii—each with its unique taste and texture. It’s a testament to how salt connects cultures, geography, and even personal experiences.

Salt and Fasting: Why You Need More When You Fast

During fasting, the body excretes more sodium because it is not getting it from food, particularly carbohydrates, which typically provide a steady stream of salt. Therefore, replenishing electrolytes during fasting is crucial for preventing fatigue, headaches, and muscle weakness.

I recommend adding a pinch of high-quality sea salt to water during fasting periods to maintain electrolyte balance and prevent dehydration. It makes an immediate difference in energy levels and overall well-being.

Conclusion: Embracing Salt as a Vital Nutrient

Salt is not the enemy—it’s an essential, life-giving nutrient. Whether you’re an athlete, someone focused on longevity, or just looking to optimize your health, increasing your intake of high-quality salt can dramatically improve your well-being.

As a surfer, I’ve always loved the taste of salt on my skin after being out in the ocean. There’s something deeply primal about it, a reminder that salt is in our blood, our sweat, and even our tears. It’s time to reclaim salt as the nutritional powerhouse it is, reject the outdated fear of it, and embrace its benefits for a healthier, stronger, and more vibrant life.

Salt is life. Let’s start treating it that way.
