What is Nordur Salt... Really?
Perhaps you have heard that sea salt is unprocessed and therefore contain more trace minerals than ordinary table salt. Perhaps you have wondered what trace minerals actually are. Perhaps you wondered what exactly Nordur Salt really is?
As you might know, Nordur Salt is produced with a Danish-Icelandic production method dating back to 1753. We start by pumping fresh sea water into our big, grey submarine, where the water is evaporated to increase the salinity (salt content). The brine is moved into open pans where the salt crystalizes on the surface, then drops to the bottom where it is finally hand harvested and dried. The whole process is CO2 neutral because all energy and heating comes from leftover geothermal water from our neighboring seaweed factory and from the nearby hot spring in ReykhĂłlar.
In this process there is nothing added and nothing taken away except the water we evaporate. This means that all you get are pure, crunchy salt flakes filled with lots of minerals from the Arctic Sea.Â
Nordur Salt contains both macro minerals and trace minerals. Macro minerals are minerals that you need large amounts of in your diet, large being more than 100mg/day. These are minerals such as sodium, chloride, potassium, phosphorus, magnesium, sulfur, and calcium. Trace minerals are needed in quantities below 100mg/day and include copper, chromium, fluoride, iodine, iron, molybdenum, manganese, selenium, and zinc. Macro minerals make up to 1% of your total body weight whereas trace minerals amount to less than 0.01%. Refined salt, such as table salt consists of approx. 40% sodium and 60% chloride by weight.
You need all of these minerals in order to survive!
As with everything else, too much or too little will have consequences for your body.Â
That is also why general recommendations to sodium intake are set between 1500-2300 mg/day, which corresponds to 3.75 â 6g of salt per day. Â
We have good news for those on sodium-restricted diets!
Because of the Nordur Salt flakesâ light, flaky crystalline structure and its low density, the salt is lower in sodium by volume than many other refined sea salts. According to our external lab analyst, this results in 260mg of sodium per serving (1/4 tsp) compared to 480-580mg found in most other brands of coarse sea salt. Additionally, Nordur Saltâs pH-level is quite alkaline (pH > 7) which is good news for those wishing to eat a less acidic diet.
A little goes a long way and we always advice that Nordur Salt should be used judiciously â except when you make popcorn and fries!
You may wonder how 35.60% of sodium and 56.95% of chloride = 90,5% Sodium Chloride (we sure did!). The reason is a bit technical, but we will try to explain to the best of our ability. Seawater has more chloride than sodium, consequently some of the chloride forms salts with other minerals such as calcium, potassium, and magnesium. So, all the chloride does not bind with the sodium and therefore the sum is less than its parts. Make sense?
That was all for todayâs lesson on what makes up those beautiful salt flakes of ours.Â
