The important thing to remember is that processed salt, which is devoid of all minerals and trace elements is not the same as good-quality natural sea salt, which does contain the trace elements and minerals and is able to be absorbed by the body more easily. Processed salt actually saps the body's mineral reserves and is very hard on the body. In colder harsher seasons for those living in temperate climates, more (good quality) salt is necessary than for people living in the tropical regions for example. Moreover, practically all general restaurant food has entirely too much processed salt content and will actually age you overnight.
