ELI5: Why do we consume Sodium Chloride and not any other salts?
gpt
We do consume a few other types of salt, just not as much as sodium chloride. If you look at the container of salt in your kitchen, it probably says that it's "iodized salt", meaning it contains a small amount of sodium iodide or potassium iodide in addition to the sodium chloride. A lot of packaged foods also have potassium chloride, although people don't usually keep that in the kitchen. 

As for why? Sodium chloride tastes salty, is non-toxic, and is widely available. Many other salts lack in one or more of those three areas.
