Is the only meaningful compound in tap water, water? Or the minute amount of fluoride in it? Some trace elements don’t require much. I get your point but I tend to think consumption of anything at the margin can yield grander effects over the long term.
Discussion
Think:
1) Look at the volume of water you consume in a day vs the volume of salt
2) There are no minerals in any salts that have such a minute daily requirement that you can reach that requirement by using a small amount of salt. You WILL meet those requirements, and then some, with proper food intake
Salt is seasoning, nothing more. Trying to decide on a salt to use based off of its alleged mineral content is a waste of time, energy, and possibly money.
