What Is Salt?
The salt used in food, or table salt, is sodium chloride.
Salt is gathered from the sea or mined in places where the sea once lay (rock salt). In its natural form, salt contains a vast array of nutrients but once refined contains primarily sodium chloride.
Refined salt often includes added ingredients such as anti-caking agents, stabilisers, and iodine. Apart from the iodine, which is also essential to the human body, the additives in salt are not usually beneficial to health. Unrefined sea salt is a good alternative but should still be used in moderation.
