There are several claims about the health benefits associated with pink salt consumption. These include:
Some health benefits of the Himalayan Pink Salt:
Rich mineral content
Some sources say that pink Himalayan salt contains up to 84 different trace minerals.
As it contains up to 98 percent sodium chloride, this means that only around 2 percent is made up of these various trace minerals. Given the relatively limited quantities in which people normally consume salt, and the tiny quantity of these minerals in the salt, they are unlikely to provide any measurable or significant health benefits.
Lower sodium
Some people believe that pink Himalayan salt is lower in sodium than regular table salt. However, both types consist of approximately 98 percent sodium chloride.
As pink salt often has larger crystals than table salt, it technically contains less sodium per teaspoon. It also has a saltier flavor than table salt, meaning that a person can use less salt in a serving to achieve the same taste.
However, pink salt is also available in a smaller granule size that more closely resembles regular salt. Consider this when seasoning food and measuring sodium intake.
The American Heart Association (AHA) advises that over 75 percent of sodium intake comes from the salt already present in processed and prepared foods. Table salt does not add the bulk of sodium content to a meal.
A more natural salt
Some claim that Himalayan salt is more natural than table salt. This claim appears to have merit.
Table salt is usually heavily refined and mixed with anti-caking agents to prevent clumping, such as sodium aluminosilicate or magnesium carbonate,
Himalayan salt is less artificial and does not usually contain additives.
An aid to hydration
Some believe that adding a pinch of pink salt to meals or drinks can help the body achieve optimal fluid balance and prevent dehydration.
It is true that sodium is necessary to maintain proper fluid balance. However, this is true of sodium from other sources as well as pink Himalayan salt.
