Celtic Salt: Benefits You Can’t Ignore

Celtic salt is a mineral-rich sea salt that offers numerous health benefits. Compared to table salt, this naturally harvested salt is minimally processed and less likely to be contaminated with microplastics.

Here are four Celtic salt benefits and practical tips on incorporating this nutritious sea salt into your routine.   

What is Celtic salt?

Celtic salt is a type of sea salt harvested from certain coastal regions of France. This type of natural salt is produced by evaporating seawater in carefully controlled salt pans, leaving behind crystalized salt. 

Like many other sea salts, Celtic salt retains various minerals that are present in the ocean, resulting in a mineral-rich salt product. 

Celtic salt contains trace amounts of essential minerals such as magnesium, calcium, potassium, copper, zinc, and iron. This mineral composition is responsible for its slightly dark color, which explains why it’s also called Celtic gray salt. 

Compared to regular or rock salt, Celtic salt retains some moisture, giving it a unique texture and flavor profile. However, its moisture content also increases the risk of clumping, so it’s essential to store Celtic salt in a sealed container.

Does the type of salt you consume matter?

Yes, the type of salt you consume matters.

Regular table salt is typically bleached and heavily processed, resulting in a salt product without significant mineral content. In addition, table salts are often combined with sodium aluminum silicate, an anti-caking compound that prevents clumping. 

According to a study published in Emergency Medicine International, chronic exposure to aluminum compounds can have neurotoxic effects and may increase the risk of Alzheimer's disease.

In contrast, sea salts and certain rock salts, including Himalayan salt, aren’t excessively processed, retain essential trace minerals, and typically don’t contain chemical anti-clumping agents. 

However, both table and sea salt can be contaminated with microplastics due to the widespread plastic pollution of the world’s oceans. 

However, evidence published in Scientific Reports found that French sea salt products were less likely to be contaminated than salt varieties harvested in Portugal or Australia. 

To minimize microplastic exposure, it’s crucial to opt for a Celtic salt that has been produced using filtered ocean water free of impurities, microplastic, and other environmental pollutants.    

Why you need sodium chloride in your diet 

Most sea salts contain around 97 percent sodium chloride, an essential electrolyte that dissolves into sodium and chloride ions when suspended in water.

Both sodium and chloride are needed to maintain electrolyte balance, which is crucial for regulating bodily fluids, muscle function, and nerve signal transmission. 

Chloride ions also help regulate the body's acid-base balance, which is vital for maintaining optimal pH levels. 

Low salt intake can increase the risk of heart attacks and electrolyte imbalances and may disrupt nerve and muscle functioning. 

In addition, research published in the Journal of Insulin Resistance found that inadequate sodium intake can increase insulin resistance, a leading cause of diabetes. 

The authors concluded, “Low-salt diets lead to systemic or vascular insulin resistance, glucose intolerance, and elevated fasting insulin.”

However, excessive salt consumption can also have detrimental health effects. 

Consuming too much sodium, especially in combination with low potassium intake, can lead to significant fluid retention, which is linked to high blood pressure and kidney issues.   

4 potential health benefits of Celtic sea salt

In addition to being minimally processed and less likely to contain contaminants, Celtic sea salt has been linked to several health benefits. 

Here are four reasons to consider adding Celtic sea salt to your routine.

1. Source of essential minerals 

Compared to regular salt, Celtic salt contains significantly higher concentrations of electrolytes and trace minerals.

Celtic salt is a source of several essential minerals, including:

• Calcium

• Iron

• Phosphorus

• Magnesium

• Zinc

• Copper

• Manganese

• Sodium

• Chloride

In addition, Celtic salt contains trace amounts of iodine, a vital mineral that promotes thyroid health. 

2. Supports digestive health 

Sodium is a key component of hydrochloric acid (HCl), also known as stomach acid. Optimal HCl levels play a critical role in breaking down proteins and triggering the release of digestive enzymes. 

In addition, Celtic sea salt contains magnesium. This essential mineral helps regulate smooth muscle function in the digestive system and enhances the activity of enzymes involved in nutrient absorption and energy production.

3. Helps strengthen immune defenses 

In addition to sodium’s role in maintaining the body’s fluid balance, mineral-rich salt can benefit the immune system.  

Trace minerals, including zinc, iron, copper, manganese, and selenium, play essential roles in the development and function of immune cells while regulating balanced immune responses. 

Although Celtic salt contains only small amounts of these nutrients, regular consumption, in combination with a nutritious diet, can contribute to optimal nutrient stores and help prevent trace mineral deficiencies. 

Due to its role in stomach acid production, salt can also help defend against invading microbes that enter the body through the digestive tract, potentially preventing gastrointestinal infections.

4. May aid blood pressure regulation

Consuming Celtic sea salt could benefit individuals with high blood pressure, also known as hypertension.

A study published in Food & Nutrition Research found that sea salt varieties are less likely to contribute to elevated blood pressure than regular table salt. The authors suggest that this effect is linked to the potassium content in sea salts.

Potassium is a crucial electrolyte involved in the body’s fluid balance and blood pressure regulation. Celtic sea salt may offer an excellent alternative to mineral-depleted table salt for those at risk of hypertension or heart disease.  

How to use Celtic salt 

Celtic salt's mineral composition and moisture content add depth and complexity to savory dishes without overpowering them. This makes Celtic salt an excellent finishing salt that provides flavor and texture when sprinkled onto grilled meats, fish, salads, roasted vegetables, and even desserts. 

In addition to seasoning foods, Celtic salt is a source of essential electrolytes and can help promote optimal hydration and electrolyte balance. 

This may be especially beneficial for individuals at increased risk of dehydration due to excessive sweating, athletes with heavy exercise routines, or those practicing intermittent or prolonged fasting.  

General salt intake recommendations suggest limiting salt intake to two grams daily. However, certain individuals may require a significantly higher salt intake to maintain electrolyte balance.    

Fasting and excessive sweating can trigger fluid loss, leading to electrolyte depletion and dehydration, linked to headaches, muscle cramps, fatigue, and dizziness. 

“To maintain a good ratio of sodium chloride and essential minerals, I recommend taking between one to two teaspoons of mineral-rich Celtic or Himalayan salt per day, ” explains Dr. Berg. 

Adding Celtic salt to drinking water can be an excellent strategy to promote optimal fluid levels and replenish electrolytes. In addition, salt-infused water doesn’t contain any calories, and taking salt won’t break a fast.  

How much Celtic salt you should add to your routine also depends on your overall salt intake. Individuals who regularly consume processed foods typically consume more salt than the body needs, and adding Celtic salt may increase the risk of high blood pressure.

In addition, people taking hypertensive drugs and those with cardiovascular issues should consult a healthcare provider before increasing salt intake to minimize the risk of side effects.

Key takeaways

Celtic salt is a nutritious sea salt that contains various essential minerals and electrolytes, including magnesium, potassium, sodium, chloride, zinc, and copper. 

In addition to serving as an excellent seasoning, there are various Celtic salt benefits, including enhanced immune defenses, digestive health, electrolyte balance, and blood pressure regulation. 

Sea salt is considered a healthier choice than regular salt as it’s less likely to raise blood pressure, making it a nutritious alternative for individuals at risk of hypertension or cardiovascular disease.
