More than nine out of 10 people accept too much salt can damage their health but most do not realise what the risks are, according to new research.
Almost two thirds (61pc) of more than 2,000 people questioned told researchers they thought salt increased their risk of heart disease.
But only a third were aware of an increased risk of a stroke (34pc) or kidney stones and kidney disease (27pc).
One in 10 (13pc) linked salt to obesity and only around one in 20 associated high salt intake with stomach cancer (6pc) or osteoporosis (4pc).
The survey was carried out for the charity Consensus Action on Salt and Health.
Firth film has its premiere
The premiere of A Single Man, the Bafta-nominated film starring Colin Firth, takes place tonight.
The much-acclaimed debut feature film from fashion designer Tom Ford sees Firth play George Falconer, a 52-year-old British college professor who is having difficulties finding meaning to his life after the sudden death of his long-term partner Jim (Matthew Goode).
Set in Los Angeles in 1962 during the Cuban missile crisis, the film follows George through a single day, as a series of events and encounters leads him to decide if there is a meaning to life.
