One in ten of the salads sold on the high street contain more salt than a Big Mac, a new survey has found. They have more than the 2.1g contained in a McDonald's Big Mac - giving those who consume them more than a third of their recommended 6g daily limit in one dish. This is not the first time such salads have been attacked as unhealthy: last year a similar survey found that some contained more fat than a Big Mac. Consensus Action on Salt and Health (Cash), a charity, said that a Spicy Crayfish Noodles salad from Eat contains 3.51g of salt The other saltiest salads from high street cafes and fast food outlets were Pret A Manger’s Super (Duper) Humous Salad (3.2g), KFC's Zinger Salad with dressing (3.1g) and its Original Recipe Chicken salad with dressing (2.9g), and McDonald's Crispy Chicken and Bacon Salad with dressing (2.6g). The Food Standards Agency (FSA) recommends adults eat no more than 6g of salt a day - about a teaspoonful - to minimise the risk of high blood pressure, stroke and heart disease. Professor Graham MacGregor, of the Wolfson Institute of Preventive Medicine, who is chairman of Cash, said: "It is absurd that only six salads contain less salt than a packet of crisps. "Clearly the manufacturers still have a long way to go if we are to reduce our salt intake to 6g a day and save the maximum number of lives. "Every gram of salt removed from our diet is estimated to prevent 6,000 deaths from heart attacks, heart disease and strokes per year, creating potential healthcare savings of £1.5 billion per year." A spokesman for Pret said: "While it can be tricky to reduce salt in products without compromising taste, we are committed to meeting the Food Standard Agency’s targets and are working hard to make reductions below those set out for 2012. "At present we offer the salad with the lowest level of salt in the UK, while all of Pret’s food complies with the FSA’s current salt guidelines.”
