How much salt do we need?

Based on the requirements of a human body, an average adult requires an intake of 4.2g salt per day. The minimum requirement is 1.5g. 

The government recommends an intake of 6g salt per day for an adult and less for children. 

At the moment the average adult intake is 10-12g. Pro-salt campaigners argue that any healthy body will process just the right amount of salt it needs and the kidneys will dispose of any surplus.
