What is salt?

Salt is a mineral which is made up of sodium and chloride. In food it helps to enhance flavour and acts as a preservative. In our bodies it helps to regulate and control normal body functions.

Where does salt come from?

Salt occurs naturally in sea-water. A deposit is left when an area of sea-water becomes enclosed, and the sun causes the water to evaporate. Over many millions of years, other sediments have been deposited above the salt, leaving the beds of rock salt, or halite below the surface.

Salt in the body

We have salt in every cell of our bodies. It plays a crucial role in keeping our bodies functioning properly, especially by maintaining the balance of our fluids, which carry oxygen and nutrients around our bodies. The two elements of salt - sodium and chloride - each play a variety of crucial roles in our bodies. A healthy body processes just the amount of salt it needs and the kidneys dispose of any excess.

How much salt should I consume?

A small amount of salt is crucial for controlling the balance of water in the body and keeping our muscles and nerves working properly, however it is important to not consume too much. Too much salt can raise your blood pressure, which can increase the risk of heart disease and stroke. Government guidelines state that we should consume a maximum of 5g per day.
