Shop-bought soups contain on average more 'hidden' salt per serving than some ready meals, according to a new report.
A survey of 576 varieties found that almost half had more than the recommended 0.6g of salt per 100g. The average salt content per soup serving was 1.6g.
Over a fifth of products surveyed had more than 2g of salt per serving – one third of an adult's daily recommended intake.
Caroline Butler, Care Advisor at Diabetes UK, said: “Everyone, particularly people with diabetes, should keep salt in their diet to 6g or less a day – more than this can raise blood pressure, which can lead to stroke and heart disease.
"Limiting the amount of processed foods you eat, and flavouring foods with herbs and spices instead of salt, can also help.”
Consensus Action on Salt and Health nutritionist Jo Butten said: "We are really concerned that the soups mentioned are a major hidden source of salt.
"This is particularly important, as soup generally only forms part of a meal or, in the case of instant cup soups, is drunk as a snack or as an alternative to tea or coffee during the day."
