Contrary to popular belief, rock salt is not kala namak. “It is actually known as sendha namak in Hindi, and is a highly crystalline salt. It is made by evaporating sea water and does not contain high amounts of sodium chloride (unlike table salt)”, says Dr. Anju Sood, Bangalore-based Nutritionist. It is used during Navratri across North India as a fasting ritual. It facilitates the cellular absorption of minerals, and plays an important role in replenishing the body’s electrolytes and maintaining the pH balance.
