Here's a little thought about pink salt (I found it on the net):
I have read and heard that Hymilayan sea salt contains 84 naturally occuring elements. How many elements are in a complete vitamin pill? 30? 40? The discolored salt crystals contain about 30 elements that you don't want, like lead, mercury, cadmium, antimony astatine , arsenic, uranium, cesium, and the list goes on. Any health fanatic would freak out if you asked them if you could put these poisons in their food or salt. Francium, uranium, cesium, plutonium, neptunium and some of the other metals are radioactive. If you can get a more pure refined salt, I think it would be worth it. Just check the anti-caking agent for aluminium or cyanide agents.
