Although after the 19th century, red Hawaiian salt produces in a large amount for export in American Northwest.

Composition of Hawaiian salt

Let’s take a closer look at red Hawaiian salt composition (1).

Compound Amount
Moisture content (%) 0.91
Sodium chloride(%) 84
Calcium (μg/g) <0.008
Magnesium (μg/g) 1.20
Phosphorous (μg/g) <0.6
Potassium (μg/g) <0.95

Hawaiian salt benefits

1. Presence of naturally occurring minerals and electrolytes

Hawaiian red salt contains more than 80 healthy minerals, mainly consist of sodium and chlorine as well as sufficient amounts of iron (digestible) and low level of calcium, potassium, magnesium, phosphorus, sulfur, and other minerals as impurities. These nutrients help to regulate organ function and maintain electrolyte levels within the body (2).

2. Longer salt taste intensity

Hawaiian red salt dissolves slowly but salt taste lasting for just over one minute (66.3 s) as compared to Kosher salt which may be helpful to reduce food intake in obese persons (1, 3).

3. Keep skin healthy

Hawaiian red salt contains clay and hence it can be used as a face scrub or facial mask in combination with oil like coconut or olive which helps to attract and removes dirt and impurities trapped under the skin as well as smoothes and brightens the skin.

4. Lower or equal sodium content

Hawaiian red salt contains a lower or equal amount of sodium (84 % sodium chloride) as table salt which helps to maintain sodium-potassium balance ratios thus protect from various diseases.

Use as a detoxifying agent- half teaspoon Hawaiian salt in 1 glass of water to purify the body.

Red Hawaiian salt contains a rich amount of iron oxide which has digestible dietary properties and black Hawaiian salt claim to detoxify the body however due to the lack of research or scientific evidence not sure about the treatment of any condition.

2. Is Hawaiian salt and sea salt are the same?

A research study suggested that the darker color of salt showed a higher concentration of impurities and trace minerals that further affect the taste and nutritional value of the salt. The red and black color of Hawaiian salt represents a rich source of minerals than white one (normal sea salt) Although both the salt is obtained from the sea and affected by ocean pollution which led to the addition of trace amounts of heavy metals and microplastics but more research is needed to confirm this.
