4. May aid weight loss

Noted studies have shown that increasing the intake of salt can increase the risk of obesity [6] [7]. And black salt on the other hand, contains low amounts of sodium which may help in managing weight. However, there is limited study available to support this point and further studies are needed.


5. May reduce water retention

Water retention occurs when excess water builds up in your body, especially in the abdomen, legs and arms leading to swelling, bloating, stiffness in the joints, weight gain, aching of affected body parts and changes in skin colour and puffy skin. One of the causes of water retention is consuming too much of salt so, switching to black salt which is naturally low in sodium can help reduce water retention. However, further research is needed to understand the exact mechanism responsible for this benefit [8].


6. May enhance skin and hair health

As black salt contains a significant amount of minerals, it may help improve skin and hair texture. Anecdotal evidence suggests that black salt may boost the growth of your hair and detoxify your body to remove all toxins, thereby enhancing hair and skin health, respectively.

Black Salt Vs Table Salt

Black salt is different from table salt in terms of manufacturing process and taste. Himalayan black salt is naturally pink in colour and traditionally it was combined with other herbs, spices and seasoning and heated to high temperatures.

Today, many manufacturers make synthetic black salt by mixing sodium chloride, sodium sulphate, ferric sulphateand sodium bisulphate with activated charcoal and then it is heated to create the final product.

On the other hand, table salt is obtained from large rock salt deposits and then processed and refined, stripping off most of the trace minerals.

Black salt is less processed and less likely to contain harmful preservatives or additives and table salt, on the other hand contains anti-caking agents which is harmful to health.

Black salt has a unique earthy, smoky flavour, whereas table salt has a salty taste.
