More than 70 per cent of people that took part in the poll, carried out by Associated Newspapers, said they did not believe that advertising curbs would improve healthy eating or reduce obesity levels among children.
Almost 85 per cent said they believed this could best be done by parents. Only 5 per cent thought government legislation to reduce the amount of snack-food and soft-drink advertising further would be effective.
The poll, which was carried out among 1,532 so-called "Middle Englanders", found that only 4 per cent blamed advertising as a main cause of obesity. Only 1 per cent believed the ad industry bore the greatest responsibility for tackling diet problems.
