Black salt has gained popularity as a more natural, mineral-rich alternative to regular table salt. But does it actually offer better health benefits? Let’s take a closer look at the differences, potential advantages, and risks of each type.


What Is Black Salt?

Black salt, or kala namak, is a type of rock salt commonly used in Indian and South Asian cuisine. Known for its distinctive sulfur-like aroma and savory, umami flavor, black salt is often added to vegan dishes to mimic the taste of eggs.

It typically has a pinkish-gray or pinkish-brown color, despite its name, and is less processed than regular salt.


Types of Black Salt

There are several varieties of black salt, each with its own use and composition:

  • Black Himalayan Salt: Most common type, with a pungent taste, often used in Ayurvedic remedies and vegan cooking.

  • Black Lava Salt: Also called Hawaiian black salt, made by mixing sea salt with activated charcoal for a smoky flavor.

  • Black Ritual Salt: Not edible. Made from ashes, charcoal, and salt, used in spiritual rituals or folk practices.


Nutritional Comparison: Black Salt vs. Regular Salt

Feature Black Salt Regular Table Salt
Processing Minimally processed (varies by brand) Highly refined
Taste Sulfuric, savory Salty, sometimes iodized
Minerals Retains iron, calcium, magnesium Fortified with iodine, may contain anti-caking agents
Sodium (per tsp) ~420 mg ~2,330 mg
Sodium (per 100g) ~38,200 mg ~38,300 mg
Color Pinkish-gray White
Texture Coarse, grainy Fine, smooth

 


Health Benefits of Black Salt

  • Trace minerals: Contains small amounts of iron, magnesium, and calcium, which support blood, nerve, and bone health.

  • Antioxidants: Some studies suggest black salt is higher in antioxidants, which may help reduce oxidative stress.

  • Digestive aid: Used in Ayurvedic medicine to relieve heartburn, bloating, and gas.

However, most of these benefits are minimal when consumed in normal quantities.


Health Benefits of Regular Salt

  • Iodine Fortification: Table salt is typically iodized, helping prevent iodine deficiency and supporting thyroid health.

  • Anti-caking agents: These keep salt free-flowing and are considered safe for consumption.


Risks and Considerations

  • Sodium intake: Both salts are high in sodium and should be consumed in moderation. The American Heart Association recommends no more than 2,300 mg/day.

  • Iodine deficiency: Black salt lacks iodine, so you'll need to get iodine from other foods like seaweed, eggs, or dairy.

  • Microplastics: Studies show black salt may contain more microplastics than sea salt, posing potential health risks.

  • Fluoride content: Some black salts contain higher fluoride levels, which may affect dental health in children.


Oxidative Stress and Salt

Oxidative stress is caused by an imbalance between free radicals and antioxidants in your body. It’s linked to chronic inflammation, aging, and diseases like cancer. Antioxidants in black salt may help neutralize free radicals—but again, only in trace amounts.


Which Salt Should You Choose?

There’s no strong evidence that black salt is healthier than regular salt. Here's a simple breakdown:

  • Choose black salt if you enjoy its taste or want a less processed option.

  • Stick with table salt if you're concerned about iodine intake, especially if you’re pregnant, vegan, or have limited dairy and seafood in your diet.

Ultimately, the decision comes down to personal preference and dietary needs.


A Quick Review

  • Black salt is less processed and may offer trace minerals and antioxidant content, but its health impact is minimal in typical serving sizes.

  • Regular salt is fortified with iodine, essential for thyroid health, but it’s more processed and contains additives.

  • Both salts should be used sparingly due to high sodium content.
