Nearly a quarter of all soup bought in supermarkets contains too much salt, with one brand containing more salt than two McDonald’s cheeseburgers, according to research.

Soup has long had a reputation for being a healthy choice for lunch. The analysis of nearly 500 varieties of tinned and chilled soups sold in supermarkets found that 23% contained too much salt.
