Whether it is a classic Chicken Club or a fresh Salmon and Cream Cheese, sandwiches remain a lunchtime staple for millions across Britain. However, a recent study may prompt consumers to reconsider their choices when selecting meal deals. Researchers from Action on Salt and Sugar have identified popular sandwich options that contain alarmingly high levels of salt.
High Salt Content in Popular Sandwiches
An analysis of 546 sandwiches, wraps, rolls, and baguettes revealed that nearly half, 44 percent, carry a red 'high' salt warning on their packaging. The worst offender is GAIL's Smoked Chicken Caesar Club, which contains a staggering 6.88 grams of salt. To contextualise, this is equivalent to nearly 10 rashers of bacon or five McDonald's Cheeseburgers. Moreover, this sandwich also contains 1,067 calories, exceeding half the daily recommended intake for women.
Sonia Pombo, Head of Research and Impact at Action on Salt and Sugar, commented: 'Most people choose sandwiches for lunch for their simplicity, convenience and affordability. But what they are actually eating can be a full day's worth of salt hidden between two slices of bread.'
Health Risks of Excessive Salt
While salt enhances flavour, excessive consumption can lead to high blood pressure, increasing the risk of heart attacks and strokes. The NHS advises adults to consume no more than 6 grams of salt per day, yet many unknowingly surpass this limit. The NHS notes that approximately three-quarters of dietary salt comes from packaged foods such as bread, breakfast cereals, meat products, and ready meals, as well as takeaways and restaurant meals.
Sandwiches with Highest Salt Levels
The study analysed 546 products from supermarkets and high street chains. Overall, 12 percent exceeded salt targets. Following GAIL's Smoked Chicken Caesar Club, the next highest was GAIL's Smoked Salmon Bagel with Schmear and Pickled Pink Onions at 4.2 grams. Other notable high-salt options include PAUL's Rosette Cheese Salami Gherkin (4.19g), Pret A Manger's Ham and Grevé Baguette (3.85g), and Subway's Spicy Italian Wrap (3.8g). Further offenders are Tesco's Fully Loaded Hot Honey Halloumi, Falafel and Pickled Slaw (3.78g), Tootoomoo's Sriracha Pork Sando Sandwich (3.7g), and Sainsbury's Kitchen Deli Pastrami, Cheddar Cheese and Gherkin Mustard Mayo (3.67g).
Low-Salt Alternatives
Conversely, Subway's Veggie Delite Sub was the least salty, containing just 0.60 grams of salt. Pret a Manger's Avo, Olive and Toms Half Baguette (0.82g), Caffè Nero's Chicken, Tomato and Basil Hot Wrap (1.08g), and Greggs' Tuna Mayonnaise and Cucumber Sandwich (1.1g) are also low-salt options. Products from Pollen and Grace, The Gym Kitchen, and Urban Rajah met all calorie and salt reduction targets with no red labels. Among retailers, Asda and Lidl achieved full compliance with salt targets.
Wide Disparities Highlight Need for Action
Action on Salt and Sugar emphasises that wide differences between similar products demonstrate high salt levels are not inevitable. The group is urging the UK government to enforce stricter regulations on salt in sandwiches. Sonia Pombo stated: 'More than 20 years after the first set of salt reduction targets were introduced, it is frankly unacceptable that some companies continue to sell sandwiches that exceed an adult's daily limit in one go. Voluntary action has been allowed to drift for too long, and the result is a food environment that continues to put public health at risk. The Government must now step in with tough, mandatory measures, because leaving this to industry goodwill has clearly failed.'
Dr Pauline Swift, Consultant Nephrologist and Chair of Action on Salt and Sugar, added: 'Too much salt drives up blood pressure, one of the biggest causes of preventable strokes, heart disease and kidney disease. People should not be exposed to a hidden health risk every time they buy lunch. Ministers need to stop relying on voluntary promises and start taking prevention more seriously.'
This study follows a previous report by the group highlighting dangerous salt levels in supermarket soups, with Soup Head's Tom Yum Soup topping the list at 3.03 grams per 300g pack.
