Table salt is a crystalline seasoning made mainly of sodium chloride. The figures here describe table salt as supplied, rather than salt added to a prepared dish. Per 100g, it contains 98g of salt and 39300mg of sodium, with an energy content of 0 kJ.

Sodium helps regulate fluid balance and supports normal nerve and muscle function. However, a high salt intake can raise blood pressure. For people watching their salt intake, both salt added during cooking or at the table and salt already present in foods contribute to the total. The full nutrient figures are given in the tables below.
