That's pretty rare in the modern world - most people chronically consume too much salt.

This recent (Apr 2017) interview[0] with Prof. Graham MacGregor[1] is really interesting on the topic of salt consumption. He says most people need add no extra salt to their food, relying instead on the small, naturally occurring amounts in the things we eat. I've done exactly this and noticed no ill effects (cramps, etc.).
