Where salt in food come from?

Answer 1

Deep-Shaft Mining

Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground sea beds. Most salt produced this way is used as rock salt. Solution Mining In solution mining, wells are erected over salt beds and fresh water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation. Most common table salt are produced this way.

Solar Evaporation

Salt is harvested through solar evaporation from seawater or salt lakes. Wind and the sun evaporate the water from shallow pools, leaving the salt behind. It is usually harvested once a year when the salt reaches a specific thickness. This only works in areas with low rainfall and a lot of sun - Mediterranean countries and Australia for example.

Or if you're talking out the salt in meat, that's either added or was ingested by the animal before they were killed.
