Did you know that salt is often referred to as “white gold”? But why?
Salt has always been an essential element in human civilization for centuries. Its significance goes beyond culinary uses, deeply intertwining with human physiology and health. For a very long time, this simple-looking ingredient has been used in the kitchen to preserve foods. At a time when every season had something new for mankind, spoilage of food was very common. At that time, salt proved itself to be a valuable resource as human society evolved.
In this blog, we will explore the critical role of salt in human physiology, its functions, and potential health impacts. We will also talk about the good salt alternatives that are important for a healthy body.
The Vital Role of Salt in Human Physiology
Sodium is not the evil here; overconsumption of sodium is!
Sodium chloride (NaCl) is the main component of salt, which is essential for several physiological functions. Ions of sodium and chloride are essential for sustaining the following body processes. Let’s see, what it does:
1. Fluid Balance - One important factor regulating the extracellular fluid balance is sodium. It aids in maintaining the ideal fluid balance inside and outside of cells, which is essential for both general homeostasis and cellular function. The kidneys and hormones like antidiuretic hormone (ADH) and aldosterone strictly control the body's sodium and water balance.
2. Nerve Transmission - A crucial part of nerve impulse transmission is played by sodium ions. An important biological process that keeps the electrochemical gradient across nerve cell membranes intact is the sodium-potassium pump. This gradient facilitates nerve impulse transmission, which allows the brain to communicate with different parts of the body.
3. Muscle Function - The passage of potassium and sodium ions across muscle cell membranes is necessary for muscular contraction. Sufficient salt levels are necessary for the heart muscle, which circulates blood throughout the body, to operate properly. Therefore, doctors recommend striking the right balance when including salt in the diet or opt for better salt substitutes like Salicornia salts.
4. Nutrient Absorption - Sodium plays a role in the active passage of some nutrients, such as glucose and amino acids, across cell membranes. The body needs these building blocks and energy, and this process is essential for nutrition absorption in the intestines. But most of the regular salts do not have the right amount of minerals, instead, they are just packed with more sodium content. Ergo, doctors recommend taking healthy salt substitutes like salt substitute with potassium or Salicornia salt, which is packed with all vital nutrients such as calcium, iron, magnesium, Vitamin A & B3, antioxidants and more.
Health Impacts of Salt
While salt is essential for health, both excess and deficiency can lead to serious health issues. Understanding these impacts is crucial for maintaining optimal health.
High salt intake is linked to hypertension and cardiovascular diseases. Excess sodium causes high blood pressure, a major risk factor for cardiovascular diseases. Sodium increases blood volume by retaining water, which puts extra pressure on blood vessel walls. This also causes bloating and edema.
Prolonged high blood pressure can permanently damage the cardiovascular system, increasing the risk of heart attacks, strokes, and heart failure. Excessive sodium intake can overwork the kidneys, leading to kidney disease or worsening existing kidney conditions. It can also cause calcium to be excreted in the urine, potentially leading to weakened bones and osteoporosis over time.
On the other hand, salt deficiency can also have detrimental effects such as hyponatremia. It is a condition characterized by low sodium levels in the blood, leading to symptoms like fatigue, headaches, nausea, and in severe cases, seizures and coma.
A very low sodium diet can also induce muscle cramps and spasms. Sodium is crucial for brain function as well. Insufficient levels can impair cognitive functions and lead to confusion and lethargy.
