Explain Sodium
Sodium (Nu) : In sodium-restricted diets, no salt is added to the diet which still provides approximately 50 mmoL Na. Foods containing high Na content must be avoided and the examples include processed or cured meats, tinned or smoked fish, tinned vegetables and soups, dehydrated and pre-packed meals, salted biscuits, nuts and crisps. There are very low Na diets as well which contain 20 mmoL Na.
