Understanding the Salt Spectrum: Beyond Standard Table Salt
For decades, the standard grocery store table salt has been the go-to for seasoning and cooking. However, due to its heavy processing, which strips it of natural minerals and often adds anti-caking agents, many are now exploring unrefined alternatives. These natural salts, including Celtic salt and Real Salt, are gaining popularity for their perceived health benefits and more complex flavors. This shift reflects a broader consumer trend toward more natural and unprocessed food ingredients.
What is Celtic Salt?
Celtic salt, also known as sel gris or 'gray salt', is a type of sea salt traditionally harvested from coastal regions in Brittany, France. The salt is collected using centuries-old, artisanal methods, where seawater is channeled into shallow, clay-lined salt marshes. The water naturally evaporates under the sun and wind, leaving behind coarse, moist, and mineral-rich salt crystals. The distinctive gray color comes from the clay lining the ponds and the high moisture content.
Characteristics of Celtic Salt
- Harvesting: Hand-raked from clay-lined coastal marshes.
- Mineral Content: Retains numerous trace minerals like magnesium, potassium, calcium, and iron due to minimal processing. Magnesium content is often cited as a key differentiator.
- Flavor Profile: A mild, briny, and slightly earthy taste, which many chefs prefer for a finishing salt.
- Moisture: Naturally moist, which gives it a unique texture.
What is Real Salt?
Real Salt is an unrefined rock salt mined from an ancient underground salt deposit in Redmond, Utah. This deposit is the remnant of a prehistoric sea that was sealed off millions of years ago by volcanic ash and bentonite clay. This geological isolation means the salt has been naturally protected from modern-day ocean pollutants, such as microplastics and heavy metals. The mining process uses a 'room and pillar' method, which is considered sustainable and has a minimal environmental impact. Real Salt's characteristic pinkish or reddish color is a result of the trace minerals, particularly iron, present in the deposit.
Characteristics of Real Salt
- Harvesting: Mined from an ancient, underground seabed in Utah.
- Mineral Content: Contains over 60 trace minerals, including potassium, iron, calcium, and zinc, alongside its primary sodium chloride content. The natural balance of minerals is often emphasized.
- Flavor Profile: A subtly sweet and rich flavor, preferred by many home cooks and professional chefs.
- Sourcing Purity: Promoted as being free from modern-day ocean pollutants.
Celtic Salt vs. Real Salt: A Head-to-Head Comparison
To help you decide which is best for your needs, here is a detailed comparison.
| Feature | Celtic Salt | Real Salt (Redmond) |
|---|---|---|
| Source | Modern seawater from coastal marshes, primarily in France. | Ancient, prehistoric seabed in Redmond, Utah. |
| Sourcing Method | Hand-harvested by raking salt crystals after solar evaporation. | Mined mechanically from a protected underground deposit. |
| Color | Grayish, due to moisture and clay particles. | Pink or red, from iron and other trace minerals. |
| Processing | Minimally processed and air-dried to retain moisture and minerals. | Unrefined, with nothing added or taken away. |
| Potential Contaminants | As a modern sea salt, it has the potential for exposure to environmental pollutants like microplastics. | Protected from modern contaminants by its geological history. |
| Flavor | Mild, briny, and slightly earthy. | Subtle and sweet due to its unique mineral profile. |
| Key Minerals | Magnesium, Potassium, Calcium, Iron, and others. | Potassium, Iron, Magnesium, Calcium, Zinc, and others. |
| Texture | Coarse and moist, can be ground for finer applications. | Varies from fine to coarse grains, depending on the grind. |
| Iodine | Not a reliable source of iodine unless specifically fortified. | Contains small amounts of naturally occurring iodine. |
Health Considerations: Debunking the Myths
While both Celtic and Real Salt are marketed as superior alternatives to refined table salt, it is crucial to maintain perspective on their health impacts. The primary health concern with salt is the total amount of sodium consumed, not the minuscule differences in trace mineral content. The American Heart Association stresses that excessive consumption of any type of salt can contribute to health issues like high blood pressure.
That said, the trace mineral content in unrefined salts like Celtic and Real Salt may offer marginal benefits. For instance, the presence of potassium in Real Salt helps balance sodium levels, promoting better blood pressure regulation. The magnesium in Celtic salt is often lauded for its role in hydration and electrolyte balance, but experts point out that more significant amounts are found in vegetables.
The Final Verdict: Choosing the Right Salt for You
In the debate of which is better, Celtic salt or Real Salt, there is no single right answer. The best choice ultimately depends on your personal priorities and preferences.
Choose Celtic Salt if:
- You prefer a moist, briny salt with a slightly earthy flavor for finishing dishes.
- You appreciate the traditional, hand-harvested approach and the sustainable practices involved in its production.
- You prioritize higher levels of magnesium, which is a key component of Celtic salt.
Choose Real Salt if:
- You are concerned about modern ocean pollutants and prefer a salt sourced from a protected, ancient deposit.
- You enjoy a subtly sweet, rich flavor profile in your cooking and seasoning.
- You are looking for a product mined in the USA with ethical labor and environmental practices.
- You prefer a naturally drier crystal that is less prone to clumping, although it does occur without anti-caking agents.
Both salts represent a high-quality, unrefined option when compared to standard table salt. While the health benefits of trace minerals in either are often overblown by marketing, they both offer a superior taste experience and transparency in their sourcing. The decision boils down to your palate and principles.

Frequently Asked Questions
Is Celtic salt truly healthier than table salt?
While Celtic salt contains more trace minerals than heavily processed table salt, the total amount is too small to provide significant health benefits. Its primary advantage is being unrefined, without additives or bleaching.
Does Real Salt contain microplastics?
No, because Real Salt is mined from an ancient sea bed deep within the earth, it is protected from modern environmental pollutants, including microplastics.
Do I need to add iodine to my diet if I use these salts?
Traditional Celtic salt does not contain added iodine. While Real Salt contains a small amount of natural iodine, it is not a sufficient source for daily needs. If you rely on iodized salt for iodine, you should supplement from other sources, such as seafood, dairy, or a fortified product.
Which salt is better for people with high blood pressure?
All types of salt are high in sodium, and excessive consumption can contribute to high blood pressure. For managing blood pressure, the overall reduction of sodium intake is far more important than the type of salt used.
How are Real Salt and Celtic salt different in taste?
Real Salt is known for a subtly sweet and balanced flavor profile, while Celtic salt offers a milder, slightly briny, and earthy taste. The difference in taste is a result of their distinct mineral compositions.
Why is Celtic salt moist?
Celtic salt's natural moisture content is a result of its hand-harvested, solar-dried production method, where not all the water is evaporated from the crystals.
Why is Real Salt pink?
The characteristic pink or red color of Real Salt is derived from the trace minerals present in the ancient seabed deposit where it is mined, particularly iron oxide.
Can I use these salts for cooking and finishing?
Yes, both Celtic and Real Salt are versatile and can be used for both cooking and as a finishing salt. Their unrefined nature means they add a complex flavor that is distinct from standard table salt.
