A pattern of rising blood pressure among children and young teenagers could be linked to salt, research has suggested.

Scientists from America's prestigious Harvard Medical School found that over the course of a decade, elevated blood pressure became 27% more common in young people aged eight to 17.

Sodium from salt-laden foods is known to be linked to high blood pressure.

A key finding from the study was that children with the greatest sodium intake were 36% more at risk of raised blood pressure than those with the lowest.
