Reevaluating the Role of Salt in Our Diets

Sea Salt: Top 6 Essential Health Benefits

Sea Salt

Salt has been used as a natural flavoring for thousands of years, and it’s so vital to our existence that a portion of our tongues is even designated to taste saltiness. However, in recent years, salt has come under fire and has been characterized as an unhealthy substance that we should cut out of our diets in favor of heart health.

That being said, not all salt is created equal and there is definitely a difference between unrefined, mineral-rich varieties like sea salt versus salt that has been heavily processed and stripped of all of its natural nutrients.

So is sea salt good for you? Does sea salt have iodine? And which types are best when it comes to your health? Keep reading for everything you need to know about this common kitchen ingredient.

What Is Sea Salt?

All types of salt — including table salt — originate from a sea or a salty body of water, but not all salts currently on the market actually come from the oceans in existence today. What does that mean? Salts that are not sea salt are often derived from underground salt deposits left behind by seawater at some point.

Sea salt is a type of salt produced from the evaporation of current seawater. The evaporation is accomplished by either open-air solar evaporation or by a quicker vacuum evaporation process. Some of the pricier sea salts available today often come from the slower sun-fueled evaporation method. When you eat a sea salt that has experienced very little processing, you have a salt that contains health-promoting trace minerals. It also has natural flavors and colors that make it a lot tastier and more interesting to use for cooking as well as homemade beauty products.

Sea salt can be either unrefined or refined, although unrefined sea salt is generally recommended to maximize its potential health benefits. Refined sea salt, on the other hand, is washed to strip it of its trace minerals and often contains harmful food additives trigger leaky gut.

Health Benefits

1. Rich in Trace Minerals

High-quality sea salts typically contain upwards of 60 trace minerals and for specific types like Himalayan sea salt, that number is said to be closer to 84. Either way, sea salts are a great source of micronutrients.

It’s become harder and harder to obtain trace minerals from the foods we eat due to the lack of nutrient-rich soil. However, trace minerals are still abundant in our planet’s seas and oceans, from which we get a variety of sea salts. (1)

2. Prevents Dehydration and Balances Fluids

Here’s how sodium works within the body: water follows salt, which means if you increase your sodium intake too much, water retention also occurs. At the same time, the opposite is also true: a loss in sodium results in a loss in water, potentially causing symptoms like dehydration and extreme thirst.

By consuming sea salt in moderation each day, you also ensure that you are maintaining sufficient sodium levels, which helps balance your sodium-potassium ratios. Sodium and potassium are two electrolytes that work together to ensure that there is proper fluid balance in your body’s cells as well as your blood plasma and extracellular fluid. (2)

3. Loaded with Electrolytes

The minimal processing of unrefined sea salt enables it to retain much of its natural mineral content. Sea salt contains many of the major electrolytes, like sodium, magnesium, calcium and potassium, that are absolutely essential to good health.

Electrolytes have so many important functions — from regulating your heartbeat to allowing your muscles to contract so that you can move. Sea salt in moderation can help in avoiding an electrolyte imbalance, which can cause all kinds of serious negative symptoms, including some that are potentially deadly. (3)

4. Promotes Brain, Muscle and Nervous System Function

As a good source of sodium, sea salt is essential for proper brain, muscle and nervous system function. Not only does sodium play a role in regulating your body’s fluid balance, but it’s also required for the transmission of electrical signals in the body. Why is this so important? Without the proper transmission of electrical signals in the body, so many things can get thrown off.

Without this communication system working as it should, the brain, muscles and nervous systems are especially inclined to suffer. Both too much and too little sodium cause cellular malfunction. So as much as you hear about making sure you don’t get too much salt in your diet, it’s also absolutely just as important to make sure we get enough. (4)

5. Supports Digestive Health

Not getting enough salt in your diet can also negatively impact your digestive health. In fact, a lack of salt in the diet can lead to a reduction of hydrochloric acid (HCL) in your stomach. If you have low stomach acid, it can seriously throw your digestive system out of whack, contributing to issues like heartburn, stomach pain, vomiting and constipation. (5) Consuming the right amount of sea salt can help your body produce proper amounts of HCL since sea salt provides chloride, one of the building blocks of stomach acid.

6. Promotes Nutrient Absorption

Having enough stomach acid also helps our bodies to absorb vitamins and minerals like calcium, zinc, iron, folate and vitamin B12. For this reason, consuming a high-quality sea salt regularly can help your body absorb more nutrients from the foods that you eat. This is great news since it’s not only what you eat, but how your body processes what you eat that gives your body the essential nutrients it needs on a daily basis.

Types of Sea Salt

There are many different types of sea salt available, each of which varies based on where it originates and the health benefits that it provides. Here are a few of the most common types of sea salt on the market today:

Himalayan Sea Salt

Many believe Himalayan sea salt is the purest salt available on the planet. With a history dating back to Earth’s creation, it’s believed to be composed of dried remnants of the original, primal sea.

Known as “pink gold” or “pink sea salt,” Himalayan crystal salt is actually a beautiful translucent pink and contains all of the elements found in your body. Because of the amazing nutrient load, doctors of functional medicine report that regularly eating pink Himalayan salt can help:

• Regulate the water content throughout your body
• Promote healthy pH balance in your cells (particularly your brain cells)
• Promote blood sugar health and help reduce the signs of aging
• Assist in the generation of hydroelectric energy in cells in your body
• Absorb food particles through your intestinal tract
• Support respiratory health
• Promote sinus health
• Prevent muscle cramps
• Promote bone strength
• Regulate your sleep
• Support your libido
• Promote vascular health
• Regulate your blood pressure with sufficient water and potassium intake

Celtic Sea Salt®

Another ancient commodity, Celtic Sea Salt® is comparable to Himalayan crystal salt in its composition and health benefits. Being of a grayish hue, it is naturally harvested in Brittany, France near the Celtic Sea using a 2,000-year-old Celtic method that is crucial to preserving its life-giving nutrition profile.

It’s been reported that Celtic Sea Salt® is incredibly beneficial for your health and can help:

• Alkalize the body
• Balance blood sugars
• Eliminate mucus buildup
• Build immunity
• Improve brain function
• Increase energy
• Provide electrolyte balance
• Promote restful sleep
• Prevent muscle cramps
• Regulate heartbeat and blood pressure

Interestingly, this salt retains its moisture and is moist to touch, regardless of how you store it. Think of this as a gentle reminder of its ocean source and continual life-giving properties.

Other sea salt options include:

• Fleur de Sel or  Flor de Sal: French or Portuguese for “flower of salt,” this sea salt gets its name from the patterns of crystals that resemble flowers. This is a salt that forms as a thin, fragile crust on seawater’s surface  as it evaporates. Traditionally, it was used as a salve and laxative, but today it’s most commonly used for cooking as a finishing salt.
• Flake Sea Salt (or Flaky Sea Salt): This variety of sea salt can be formed naturally or produced by a variety of methods. Often sold under the brand Maldon sea salt flakes, flaky sea salts have thin, flattened crystals that provide more surface area with less mass resulting in a quick-dissolving and crunchy salt. It’s said that flake sea salt has a saltier taste but may also contain a lower amount of trace minerals than other sea salts.
• Hawaiian Sea Salt: Hawaiian or Alaea sea salt is a traditional Hawaiian salt. Alae is a natural red volcanic clay that is added to enrich the salt with iron oxide, and it also gives this sea salt its distinctive red sea salt color but can also be found in white or black sea salt varieties. Real Hawaiian salt is pricey and hard to find outside of Hawaii.
• Italian Sea Salt: This sea salt is derived from the Mediterranean Sea along the coast of Sicily.

You can also find other specialty sea salt varieties such as coarse sea salt, smoked sea salt and iodized sea salt.

Sea Salt vs. Table Salt

Table salt and sea salt are two of the most common types of salt found on grocery store shelves and spice pantries alike. So what are the differences between sea salt vs table salt?

Table salt is mainly mined from underground salt deposits. It’s heavily processed to eliminate healthy minerals and is manufactured by taking natural salt (such as crude oil flake leftovers) and heating it to 1,200 degrees Fahrenheit. During this extreme process, the chemical composition is completely altered, destroying many of its potential health-promoting properties.

Although the salt chemical formula for both table salt and sea salt alike is mostly sodium chloride, the sea salt composition also contains more trace minerals like calcium, magnesium and potassium. Generic table salt, on the other hand, ends up being about 97.5 percent sodium chloride and a 2.5 percent balance containing an array of ingredients, including:

• Anti-caking chemicals
• Iodine to prevent goiters
• MSG and/or white processed sugar to help stabilize the iodine
• Aluminum derivatives, such as sodium silicoaluminate

Most food manufacturers add iodine to table salt, increasing the risk of consuming excess amounts. While higher intakes of iodine are generally well-tolerated by most people, it could cause thyroid dysfunction for certain people who may be more sensitive to its effects. (6) For these individuals, keeping iodized salt intake in moderation is absolutely essential, and opting for a minimally processed, non iodized sea salt in place of iodized salt may be a good option.

Sea Salt vs. Kosher Salt vs. Rock Salt

Although kosher salt is another of the most popular types of salt available, few people really understand what it is and what the differences are between kosher salt vs sea salt. Kosher salt stands out because of its large flake size and coarse texture, making it ideal for applying directly onto foods with your fingers. Because of its unique texture, kosher salt is often used for draining blood from meat prior to consumption to comply with Jewish laws, which is where it gets its name.

Rock salt, on the other hand, is a type of salt that is derived from oceans that dried up millions of years ago, leaving behind a concentrated amount of salt in the crust of the earth. This type of salt contains a wide array of important minerals and little to no moisture but is often classified as one of the purest forms of salt in existence. Himalayan pink salt is one of the most popular examples of a rock salt, but other varieties are also available which are harvested from different regions around the world.

Uses in Traditional Medicine

Sea salt has been a star ingredient in many forms of traditional medicine for centuries. In fact, ancient Ayurvedic texts even mention it and consider it essential to the function and growth of the body.

According to Ayurveda, salt should be unrefined and consumed in moderation to get the most health benefits. Sea salt is believed to act as an antidiuretic and help soothe the throat, clear the sinuses, support electrolyte balance and aid in detoxification.

Meanwhile, in Traditional Chinese Medicine, sea salt is used to cool the body and regulate levels of water and moisture. It’s also said to enhance kidney health, flush out toxins and promote proper digestion in the body.

Where to Find and How to Use

Wondering where to buy sea salt? Given its rise in recent popularity, you can find a wide variety of sea salt brands at most major grocery stores in the spice and seasoning aisle. Pay close attention to the ingredients label and select a product with minimal added ingredients to make sure you’re getting the best quality possible.

Once you’ve got your hands on some high-quality sea salt, there are limitless ways to start adding it into your routine. One of the easiest ways is to simply swap it for table salt in your favorite recipes, using it to spice up main courses and side dishes. You can also add it to desserts for a savory kick of flavor by experimenting with recipes like sea salt ice cream or sea salt caramel.

Aside from using it in cooking and baking, you can also try making some DIY beauty products with sea salt as well. Try making a dead sea salt scrub to get rid of dry skin by mixing coarse sea salt, coconut oil and your choice of essential oils. You can also make a DIY sea salt spray for hair to get beachy waves all year round using just a few simple ingredients. For the best sea salt spray, simply combine sea salt with water and a bit of aloe vera gel in a spray bottle.

Sea salt is also sometimes used for a sea salt flush or sea salt cleanse to help clear out the colon. This typically involves mixing lemon juice, sea salt and water and drinking it quickly to help produce a bowel movement.

History/Facts

Salt has always been essential to human life since humans need sodium in order to survive. The production of sea salt has been dated all the way back to prehistoric times. Since all salt either comes from dead, dried-up seas or living seas, the history of salt is equivalent to the history of sea salt.

In the sub-Sahara in the 6th century, Moorish merchants regularly traded prized salt in equal amounts (by weight) for gold. Later in 1295, the explorer Marco Polo returned from his travels telling stories of the highly impressive value of salt coins bearing the seal of the Great Khan of the Mongol empire. There were salt trade routes all over the world with the most popular one leading from Morocco south across the Sahara to Timbuktu.

The history of human civilization is said to be directly linked to salt. How so? Animals would create paths to salt licks, men would follow, turning trails into roads and settlements would grow beside these roads. As civilizations grew around the world, salt continued to be one of the main items used for trade.

Solnitsata was Europe’s earliest known town, and it was constructed around a salt production facility. According to archaeologists, Solnitsata accumulated wealth by supplying salt throughout the Balkan Peninsula.

Risks and Side Effects

Even though sea salt has some health benefits, you don’t want to overdo it. If your diet is too high in sodium, then more water is excreted by the kidneys, which can cause complications with balancing other essential electrolytes. Symptoms of having too much sodium in your diet may include bloating, lethargy, dehydration, weakness, irritability and muscle twitching.

Hypernatremia occurs when there’s an imbalance of sodium and water in your body. This condition is more common among infants who have a low intake of breastmilk or an intake of formula that was not mixed properly, older adults, people with diabetes or kidney problems, severe burn patients, people who take diuretics and those who eat heavily processed diets. Symptoms can include intense thirst, headache, confusion, irritability, restlessness and drowsiness. If you think that you may be experiencing hypernatremia, seek medical attention immediately.

Additionally, if you’re cutting table salt out of your diet altogether, it’s important to ensure you’re getting iodine from other food sources in your diet. In addition to iodized salt, you can also find iodine naturally in foods like seaweed, dairy products, seafood and eggs. If you don’t commonly consume any of these foods, opting for iodized sea salt may be a good option to make sure you’re meeting your daily needs for this key mineral.

Final Thoughts

• Sea salt is a type of salt produced from the evaporation of seawater. Because it’s less refined than other types of salt, it contains a higher concentration of trace minerals and a more intense flavor.
• In addition to being less refined and containing a richer nutrient profile, one of the main differences between table salt vs. sea salt is that table salt is often higher in additives and enriched with iodine.
• There are many different types available, including Himalayan sea salt, Celtic Sea Salt®, Italian sea salt, Hawaiian sea salt, flake sea salt and Fleur de Sel.
• The main difference between Himalayan salt vs. sea salt varieties like flake sea salt is that it is considered the purest form and has a distinct pink color due to the presence of iron oxide.

• There are also several differences between sea salt vs. kosher salt, which is a type of salt favored for its large flake size and coarse texture.

• You can easily swap it in for regular salt in your favorite recipes or try it in some beauty products by making a DIY sea salt hair spray or sea salt scrub to take advantage of its full range of benefits.
