Maximum salt a day (NHS)

Age Maximum salt
Under 1 less than 1 g
1 to 3 2 g
4 to 6 3 g
7 to 10 5 g
11 and over, including adults 6 g (about a level teaspoon)

Reading labels: salt per 100 g

Rating Salt per 100 g Sodium per 100 g
High (red) more than 1.5 g more than 0.6 g
Medium (amber) 0.3 to 1.5 g 0.1 to 0.6 g
Low (green) 0.3 g or less 0.1 g or less

If a label only shows sodium, multiply by 2.5 to get salt. Most of the salt we eat is already in foods we buy, such as bread, breakfast cereals, sauces and ready meals.
