Is Black Salt Better Than Regular Salt? Benefits and Uses

Black salt is a well-known component in Indian cooking.

It brings a distinctive taste that elevates various recipes. There are also assertions that it may offer certain health advantages.

This piece explores what black salt is, its possible health effects, and whether it’s superior to ordinary table salt.

What is black salt?

While several varieties of black salt exist, Himalayan black salt is the most frequently encountered.

It’s a rock salt sourced from salt deposits in Pakistan, Bangladesh, India, Nepal, and other Himalayan regions.

The earliest records of black salt appear in Ayurvedic medicine, a traditional holistic health system that originated in India (1).

Ayurvedic practitioners attribute therapeutic properties to Himalayan black salt. Still, whether these claims are founded on robust scientific evidence is debatable.

Curiously, despite its name, Himalayan black salt displays a pinkish-brown shade.

Summary: Black salt is a Himalayan rock salt. It has a dark pink color and is traditionally thought to have healing properties.

Types of black salt and their uses

There are three primary kinds of black salt: Himalayan black salt, black lava salt, and black ritual salt.

Himalayan black salt

Himalayan black salt is also known as Indian black salt or kala namak.

Although it’s long been praised for medicinal uses, scientific studies supporting those assertions are scarce.

With a sharp, savory, umami-rich character, it’s widely used in cooking, particularly in Asian and Indian dishes.

Because of its faint sulfurous scent reminiscent of eggs, it’s popular in vegan recipes to mimic an egg-like flavor.

Black lava salt

Black lava salt is sometimes called Hawaiian black salt, since it’s often produced in Hawaii.

Unlike Himalayan black salt’s pinkish-brown tone, black lava salt is truly black.

It provides an earthy flavor and is typically sprinkled onto dishes as a finishing salt.

Its subtle smoky notes make it an excellent complement to foods that aim for a smoky profile.

Black ritual salt

Black ritual salt, or witches’ salt, is a blend of ash, sea salt, charcoal, and occasionally black dye. It’s not intended for eating.

Although lacking scientific support, some people believe black ritual salt has protective or magical properties against negative spirits. Adherents may scatter it around their property or keep it in a jar under a bed.

While this folkloric practice is likely harmless, it’s not recommended and there’s no evidence backing its effectiveness.

Summary: There are three main black salts. Himalayan black salt and black lava salt are culinary, while black ritual salt is non-edible and used in superstition-based practices.

How is black salt different from regular salt?

Black salt contrasts with common table salt in its production methods and its flavor.

Manufactured differently

Himalayan black salt begins as pink Himalayan salt, a form of rock salt.

Traditionally, it was combined with herbs, seeds, and spices and then exposed to high heat.

Nowadays, many black salts are produced synthetically from blends of sodium chloride, sodium sulfate, sodium bisulfate, and ferric sulfate. The mixture is then combined with charcoal and heated before finishing.

The end product contains impurities such as sulfates, sulfides, iron, and magnesium, which influence its color, aroma, and taste.

These impurities are unlikely to be harmful. Sulfates are generally safe for consumption and are used in some food products to manage microbial growth (2, 3).

Black lava salt was historically linked to volcanic lava. Today it’s commonly produced by mixing sea salt with activated charcoal.

By contrast, regular table salt — the kind in most shakers — is heavily refined, which removes most trace minerals.

Table salt typically comes from extensive rock salt deposits — remnants of evaporated prehistoric seas — found in countries like the United States, Canada, Germany, Eastern Europe, and China. Various extraction techniques, using different machinery, are employed to obtain this salt.

Taste differences

Black salts tend to have deeper and more complex flavor profiles than standard salt.

Himalayan black salt imparts a sulfurous note familiar in Asian and Indian cuisine, while black lava salt contributes an earthy, smoky taste.

Regular table salt primarily tastes salty, but can also present subtle sweet, sour, or bitter undertones (4).

Table salt is also widespread in processed foods. In fact, over 75% of daily sodium intake comes from salt in processed foods (5).

Overall, salt of all varieties is added to many recipes because it boosts flavor (6).

Summary: Black salt is produced differently than table salt and usually contains more trace minerals, resulting in a more distinctive taste.

Possible health benefits

Opting for black salt might offer some potential health advantages.

For one, black salt may have lower sodium than table salt. It often includes fewer additives and is sometimes claimed to have other therapeutic effects.

May be lower in sodium than table salt

Commercial table salt can contain a higher sodium concentration than naturally sourced black salt.

Because it may be lower in sodium, black salt could be preferable for individuals with hypertension or those aiming to cut back on sodium.

Diets rich in sodium are associated with high blood pressure and can raise blood pressure in susceptible individuals (7).

Keep in mind to check the nutrition facts on black salt products, as sodium levels can differ markedly by brand.

May contain fewer additives

Black salt may have fewer additives than standard table salt because traditional black salt undergoes minimal processing.

Anti-caking agents — which have potential health concerns — are added to table salt to prevent clumping (8).

Some table salts may also include additives like potassium iodate and aluminum silicate. Potassium iodate could promote lipid oxidation, a damaging process linked to tissue harm and increased risk of disease (9, 10).

That said, not all additives are harmful.

In fact, iodizing table salt was a major public health initiative to lower iodine deficiency, which is prevalent in many regions. Iodine deficiency is a common cause of hypothyroidism and other health issues (11, 12).

Other unfounded health claims

• May contain more minerals.Some claim Himalayan black salt has higher mineral content than table salt, but research comparing the two is limited.
• May improve digestion.It’s often suggested that black salt aids digestion, acts as a mild laxative, and relieves gas and bloating. However, evidence is lacking.
• May enhance skin and hair.Because of its mineral profile, black salt is sometimes touted to benefit skin and hair, though scientific backing is minimal.

Summary: Black salt might be lower in sodium and contain fewer additives than conventional table salt. It may have other benefits, but stronger evidence is required.

Is black salt healthier?

Any higher mineral levels in black salt may be of little consequence, since the body absorbs these minerals poorly and the amount of salt consumed at one time is normally small (13).

Minerals in rock salts are often insoluble and therefore less bioavailable. Minerals are more readily absorbed when they are in soluble forms (13, 14).

Moreover, many commercially sold black salts are produced synthetically and may actually be low in minerals.

Because black salt tends to have fewer additives than table salt, it may be a preferable option if you wish to avoid anti-caking agents.

Nevertheless, moderation is key regardless of the salt variety. Health authorities recommend a daily sodium limit of 2,300 mg, roughly equal to one teaspoon of salt (15, 16).

Summary: There isn’t convincing evidence that black salt is healthier than regular table salt. Use salt sparingly and primarily to enhance flavor.

The bottom line

Black salt is a flavorful natural alternative to ordinary table salt, especially for Indian and Asian recipes that call for it.

Its unusual taste can enrich many dishes.

However, it’s unlikely to produce the dramatic therapeutic effects sometimes claimed online.

No rigorous studies directly comparing the health impacts of black salt and table salt have been conducted; more research is necessary.

For now, appreciate black salt for its distinctive flavor and culinary value.
