The study found that the retailer’s Be Good to Yourself breakfast cereal contained one of the highest proportions of salt, with a concentration almost 50% greater than sea water, according to a report in The Sunday Times.
A single bowl of the cereal contains 1.8 grams of salt, more than three times the daily requirement of 0.5 grams for an adult.
Sainsbury has announced it will be withdrawing three of the saltiest products picked out by Cash, including the breakfast cereal.
Other high salt foods identified by the study included a ‘farmhouse’ crusty loaf by Marks & Spencer, which was found to contain one gram of salt per slice, and Quaker Oat Crunchies, which had 1.5 grams of salt per bowl.
The study also highlighted high levels of salt in Wall’s micro thick sausages, Lidl’s pepperoni and ham thin and crispy giant pizza, Tesco smoked salmon fishcakes, Asda garlic chicken Kievs and Budgen Melton Mowbray pies.
