Teen salt overload due mainly to bread, cereals

The source of the salt was mainly breads and cereals (36%), but 19% came from meat products and 11% from dairy, the researchers found.

They noted that US guidelines have an even lower target, advising both adults and children to have no more than 3.7g of salt per day, equivalent to less than one teaspoonful.

The study of 340 London children, who provided 24-hour urine samples to measure salt intake, found five- and six-year-olds consumed an average 3.7g of salt per day but by age eight, intake was up to 4.72g per day.
