Salt: The Essential Mineral You've Been Told to Fear—But Shouldn't
The human body is a remarkable creation—a scoop of the Earth held together by breath. This analogy beautifully illustrates how our bodies are composed of the very elements that make up our planet. We are made of the atmosphere (the air we breathe), the ocean (the water and fluids we drink), and the soil (the produce and animal proteins we consume). These components, recycled again and again through the Earth’s natural processes, form the body we reside in. Understanding this connection helps us appreciate the essential role that elements like salt play in our health.
The Ocean Within Us:
The Body's Composition and the Role of Salt
It’s fascinating to consider that about 60% of the human body is water. But this isn’t just any water; it closely resembles ocean water in its composition. Our bodies contain a balanced mix of water and electrolytes—minerals like sodium, potassium, and magnesium, which are also found in seawater. Sodium, the main component of salt, is vital for maintaining fluid balance, nerve function, and muscle contraction.
Anyone who has tasted their perspiration has noted its salty taste. There’s a reason for that. When we sweat, our bodies release water along with essential electrolytes like sodium, which help regulate temperature and maintain fluid balance. The salty taste of sweat is a direct reminder of the ocean within us and our body's need to maintain a delicate balance of these vital minerals.
Salt is not just a dietary ingredient; it is a cornerstone of life. The trace minerals found in salt, such as magnesium and potassium, play crucial roles in our health. Magnesium is involved in over 300 biochemical reactions in the body, including energy production and muscle function, while potassium works with sodium to maintain normal blood pressure and support heart health.
Demystifying The Concerns About Salt:
Myth 1: Too Much Salt Is Bad for You
The idea that too much salt is harmful is one of the most pervasive health myths. While excessive salt intake in conjunction with a diet high in processed foods can contribute to health issues, the reality is that salt itself is not inherently bad. In fact, salt is vital for our survival.
The body has a sophisticated mechanism for regulating salt levels. When we consume more salt than the body needs, the excess is efficiently excreted through urine, sweat, and feces. The kidneys play a crucial role in this process by filtering out excess sodium from the bloodstream and excreting it via urine. This is why adequate hydration is essential—it assists the kidneys in this natural detoxification process.
Myth 2: Reducing Salt Intake Will Prevent High Blood Pressure
The connection between salt intake and high blood pressure has been overstated and has garnered more than its fair share of unnecessary concern. While there is a very small subset of the population that is salt-sensitive and may experience increased blood pressure with high salt intake, for most people, the relationship is not nearly as direct as commonly believed.
While reducing salt intake can help some individuals with salt-sensitive hypertension, the general population does not need to be overly concerned with moderate salt consumption. Moreover, other factors such as dehydration, chronic stress, and poor diet are more likely to contribute to high blood pressure, making it overly simplistic to blame salt alone.
Myth 3: All Salt is the Same
Not all salts are created equal. Most people are familiar with table salt, which is heavily processed and often contains anti-caking agents. However, there are other types of salt that offer considerably more health benefits:
Redmond's Real Salt: This salt is harvested from an ancient sea bed in Utah, and it is unrefined and free from additives, and free of microplastics. It retains a wide range of trace minerals that are beneficial to health, making it a superior choice over typical table salt.
Celtic Sea Salt: Harvested from the coastal regions of France, this salt is known for its high mineral content and slightly moist texture. It contains essential minerals like magnesium and potassium, which are vital for maintaining the body's electrolyte balance.
Himalayan Pink Salt: While true Himalayan salt contains 21 beneficial trace minerals, the market has seen an influx of fake products, with some salts being nothing more than regular salt dyed pink. It's crucial to purchase Himalayan salt from reputable sources to ensure authenticity. Fake Himalayan salt often lacks the mineral content that gives the real salt its distinctive pink hue (Standard Salts) (Sana Naturals) (The Salt Room).
Moreover, many common sea salts derived from ocean water are now contaminated with microplastics, making them a less desirable option compared to salts like Redmond's Real Salt or authentic Celtic Sea Salt.
Myth 4: You Should Avoid Salt Completely to Be Healthy
Salt is not just a seasoning; as mentioned before, it's a vital nutrient for life. Sodium, the primary component of salt, is essential for several critical bodily functions. It helps regulate nerve impulses, ensuring proper communication between the brain and muscles, and is crucial for muscle contractions, including the heartbeat. Moreover, sodium plays a significant role in maintaining fluid balance, which is vital for blood pressure regulation and overall cellular function. Excessively avoiding salt in your diet can disrupt these processes and lead to hyponatremia, a potentially life-threatening condition characterized by abnormally low sodium levels in the blood. Symptoms of hyponatremia can include headache, confusion, seizures, and in severe cases, coma or death. Thus, rather than avoiding salt entirely, it’s important to consume it in moderation to support these essential bodily functions.
Myth 5: Salt Causes Weight Gain
Salt itself does not contribute to fat accumulation or weight gain. However, high-sodium diets can lead to water retention, where the body holds onto extra fluid to balance the increased sodium levels in the bloodstream. This temporary increase in water weight might show up on the scale, leading to the misconception that salt causes weight gain. It's important to note that this is not the same as gaining fat. Once sodium levels in the body return to normal, the kidneys excrete the excess water, and the temporary weight gain dissipates. Therefore, the apparent weight gain associated with high salt intake is transient and not an increase in body fat. For long-term weight management, it's more effective to focus on overall dietary habits, physical activity, and nutritional balance rather than sodium restriction alone.
Myth 6: Low-Sodium Diets Are Healthier for Everyone
The idea that a low-sodium diet is universally beneficial is a complete misconception and the product of misleading marketing to sell products. While reducing sodium intake may be necessary for individuals with certain health conditions like hypertension, it’s not a one-size-fits-all solution. Again, sodium, found in salt, is an essential mineral, playing a key role in fluid balance, nerve function, and muscle contractions. Inadequate sodium intake particularly in individuals with high physical activity levels or those living in hot climates where sweating is more pronounced can cause symptoms like muscle cramps, nausea, dizziness, and in severe cases, can be life-threatening. Additionally, athletes and those engaging in intense physical activity may require higher sodium intake to replace the sodium lost through sweat and maintain optimal performance. Therefore, while some may benefit from reducing sodium, a blanket recommendation for low-sodium diets can overlook individual needs and may inadvertently lead to adverse health outcomes. It’s crucial to tailor sodium intake to one's specific health profile and lifestyle.
Dehydration, Not Salt - A Very Common Cause of High Blood Pressure
A significant, yet often overlooked, contributor to high blood pressure is dehydration. When the body is dehydrated, blood volume decreases, leading to a compensatory increase in blood pressure to maintain adequate blood flow to vital organs. This is particularly concerning given the high prevalence of chronic dehydration something I have written extensively about in other articles.
Though, the claim that "approximately 75% of Americans are chronically dehydrated" has been widely circulated online, it is not based on an actual study. The origins of this statistic appear to be from a media segment on a CBS affiliate in 2013, which mentioned that "up to 75% of Americans may be functioning in a chronic state of dehydration."
Regardless, of the exact percentage, what is well-documented is that chronic dehydration can lead to the constriction of blood vessels, increased heart rate, and a greater risk of hypertension, all of which are often wrongly attributed solely to high salt intake.
In this context, reducing salt intake without addressing dehydration can be counterproductive. When the body is dehydrated, reducing salt intake can exacerbate the problem by further lowering blood volume, leading to even higher blood pressure. Thus, it is crucial to maintain proper hydration levels to support healthy blood pressure, rather than focusing solely on salt reduction.
The Vital Role of Salt in the Body
Salt is not just a condiment; it is a critical component of our body's biochemical processes. Sodium, one of the primary elements in salt, performs several essential functions:
Fluid Balance: Sodium helps regulate the balance of fluids in and around cells, ensuring that cells maintain their proper shape and function. It controls the movement of water between different compartments in the body, which is vital for maintaining blood pressure and volume.
Nerve Function: Sodium is essential for transmitting electrical signals in the nervous system. These signals are necessary for everything from muscle contractions, including the heartbeat, to sensory perceptions like touch and taste. Without adequate sodium, nerve function would be impaired, leading to a host of neurological issues.
Muscle Contraction: Sodium works in concert with potassium to facilitate muscle contractions. This is particularly important for the heart, where proper sodium levels are crucial for maintaining a steady heartbeat. Imbalances in sodium and potassium can lead to arrhythmias and other cardiac issues.
Acid-Base Balance: Sodium plays a key role in maintaining the body's acid-base balance. This balance is crucial for enzyme function, which underpins nearly every chemical reaction in the body. Without sufficient sodium, the body would struggle to maintain the pH levels necessary for optimal metabolic function.
The Importance of Electrolytes: Sodium, Magnesium, and Potassium
Salt is not just about sodium; it is part of a broader group of minerals known as electrolytes, which include sodium, magnesium, and potassium. These electrolytes work together to regulate various bodily functions:
Magnesium: This mineral is involved in over 300 enzymatic reactions in the body, including those responsible for energy production, protein synthesis, and muscle and nerve function. Magnesium is also crucial for maintaining normal blood pressure and heart rhythm.
Unfortunately, magnesium deficiency is common, with some estimates suggesting that up to 50% of Americans may not be getting enough of this essential mineral. According to data from the National Health and Nutrition Examination Survey (NHANES) between 2013 and 2016, approximately 48% of Americans do not meet the Estimated Average Requirement (EAR) for magnesium through their diet. This is particularly concerning because magnesium deficiency can contribute to various health issues, including abnormal heart rhythms, increased risk of hypertension, and cardiovascular diseases. Habitually low magnesium intake can lead to changes in biochemical pathways that increase the risk of illness over time, emphasizing the importance of adequate magnesium consumption in the diet (Open Heart) (Office of Dietary Supplements (ODS)).
Potassium: Potassium is a counterbalance to sodium and is critical for maintaining normal blood pressure. It helps the body excrete excess sodium, which can mitigate the potential blood pressure-raising effects of high sodium intake. Potassium is also vital for heart function and helps prevent the formation of kidney stones and osteoporosis. Despite its importance, many people do not consume enough potassium, with the average American diet falling short of the recommended daily intake.
The Truth About Salt in Medical Treatments
If salt were truly harmful, it would not be a fundamental component of medical treatments, especially in Emergency Rooms across the world. One of the most common treatments administered in hospitals is an IV saline solution, which is essentially a mixture of water and salt.
An individual showing up in an emergency room following a stroke or a heart attack from high blood pressure, the first thing administered to the patient in the ambulance on the way to the hospital, without ever consulting doctor is 9000 - 18,000 mg of salt in an IV saline solution push. What happens? Your blood pressure begins immediately coming down.
Saline solution is used to restore hydration, balance electrolytes, and stabilize blood pressure in patients who are dehydrated or have lost fluids due to illness or injury. It’s important to note the kidneys are what release water from the body, and function by way of sodium-potassium pumps. Sodium is salt.
When we deprive ourselves of salt, the kidneys cannot excrete water from the body so, we end up retaining water which increases our blood pressure. The fix? Lasix!!! A diuretic. What are diuretics? Patented “garden-variety” SALT!!! But because it’s patented by the medical mafia, they get to convince a naive patient they’re being prescribed a drug lowering their blood pressure, when it’s anything but, and bill your insurance company a $1,000 a script.
The fact that salt is a cornerstone of such a widely used medical intervention underscores its importance in maintaining health, not threatening it.
Saline IVs are particularly effective because they replenish both fluids and electrolytes, which are lost through sweating, vomiting, or diarrhea. This replenishment helps prevent the dangerous complications of dehydration, including low blood pressure, electrolyte imbalances, and shock.
Conclusion: Salt Is Essential, Not the Enemy
The narrative that salt is bad for you is not only overly simplistic but also potentially harmful when it leads to misunderstandings about what truly contributes to health issues like high blood pressure. Salt is essential for life, playing critical roles in fluid balance, nerve function, muscle contraction, and acid-base balance. While it is important to be mindful of salt intake, especially in the context of a diet high in processed foods, it is equally important to recognize that salt itself is not the enemy.
Instead of focusing solely on reducing salt, the emphasis should be on consuming a balanced diet that includes plenty of whole foods rich in potassium and magnesium, and maintaining adequate hydration. By doing so, you will support your body’s natural functions, maintain a healthy balance of electrolytes, and promote overall health.
In summary, salt is not something to be feared or eliminated but rather understood and respected as an essential nutrient that, when consumed in balance with other electrolytes and accompanied by proper hydration, supports a healthy, thriving body.
