Pink you say?

DAMN!   I'll be back.  Something went pear-shaped, necessitating a restart.

Behold the full spectrum.  It got a look in way back here. When some of us, well, two at least, got a chuckle at the concept of 1,000,000s of year old salt going off in a few years.
     By the first odd coincidence the concept, in 2017 of its BBE in 2022, just about 13 months ago in fact.  The second odd coincidence -  my current lot has a BBE of Dec 2022.  Guess who's NOT throwing it out?   ;¬ ) 
     What called it back to mind was a mention on Farcebook also making mock of the BBE date.
     Study/analysis  suggest there may be little to be gain, but it last forever so what the heck?
"Although a study of pink salts commercially available in Australia showed Himalayan salt to contain higher levels of a range of elements, including calcium, iron, magnesium, manganese, potassium, aluminum, barium, silicon, and sulfur, and reduced levels of sodium, compared to table salt, the authors concluded that "exceedingly high intake" (a level in excess of the recommended daily salt intake by almost 600%) would be required for the differences to be clinically significant, levels at which any potential nutritional benefit would be outweighed by the risks of elevated sodium consumption such an intake would entail."
     For the amount we/I use(d) I see no reason to change a habit of many years.
I notice the current packet tells me that it's "ancient and clean, deposited millions of years ago before pollution."  It may predate pollution - BUT - when dissolved it yields  a clear solution, with a pink deposit in the bottom of the container.
