Pollution of Celtic Sea Salt / Sel Gris / Sel de Guerande
We read nothing but positive things about the popular ‘Celtic Sea Salt’, which may also be known as sel de gris or sel de guérande. Is this salt really as healthy as claimed? We read mostly about the advantages or benefits of the salt. But research has shown that there are also some negatives to the salt. These are mostly linked with the pollution of the waters (the Loire and the Vilaine) where Celtic sea salt is harvested.

In the articles below you will find more information about Celtic sea salt and its origins. The list of sources can be used to read the corresponding research.
