?Is Celtic Sea Salt Healthy?

Is Celtic Sea Salt Healthy?

Welcome back for the third installment in our “What is the Healthiest Salt?” series, where we take a closer look at the various popular types of salt, and contemplate how well they live up to their health halos. 

Last week we looked at Sea Salt, investigating the strengths and weaknesses of this popular “healthy salt alternative”. This week we’re going to talk about a specific kind of salt in this category, Celtic Sea Salt, and see if it is healthy. However, before we review the specifics of Celtic Sea Salt, let’s do a quick recap of what makes up a healthy salt.

 

What Makes Up A Healthy Salt?

The body only requires about 15 minerals, and most of those minerals also function as electrolytes. The minerals that function as electrolytes include calcium, sodium, bicarbonate, potassium, magnesium, and chloride. Keeping these electrolytes balanced in our body is very important.  The dogma that low-sodium salts are the healthiest is false.  Actually a healthy salt needs to be balanced in the key electrolytes, contaminant free, and it needs to taste good.

 

What Minerals are in Celtic Sea Salt?

As with Sea Salt, Celtic Sea Salt is created by evaporating sea water, and then what is left behind is the salt. However, this salt specifically comes from seawater near the town of Guérande in France.  The seawater is concentrated, first in clay silt ponds, and then in shallow pans that are formed in the native clay. This clay is what gives the salt its characteristic gray tint. 

When analyzed this salt is often found to have higher levels of calcium, magnesium, and potassium than table salt.  The amounts of these mineral levels in Celtic Sea Salt vary. The presence of these minerals is most likely due to the clay contamination, and just like Sea Salt, other contaminants in the ocean such as microplastics, and heavy metals can also make an appearance.

 

So, is Celtic Sea Salt Healthy?

The answer is no.  As you can see on the graph below, Celtic Sea Salt does tend to have slightly higher levels of calcium, potassium, and magnesium than table salt. However, none of these minerals are present in amounts that would impact someone’s health.  Celtic Sea Salt still contains high levels of sodium relative to the other important salts, and it has even higher relative levels of chloride than the other salt alternatives we’ve seen so far.

Because Celtic Sea Salt is almost entirely Sodium Chloride, offering other important minerals only in scant levels that are too low to make much of an impact on the body, we cannot recommend Celtic Sea Salt as a healthy salt alternative
