Some cheese contains more salt than seawater, new research has found, amid warnings about the high salt content in the majority of cheese sold in Britain.
Research published in BMJ Open found halloumi and imported blue cheese had the highest salt content, while cottage cheese had the lowest.
Large variations in salt content were found in the 612 cheeses examined - even different versions of the same cheese were found to vary.
Some types of cheddar - the most popular choice among British consumers - had much higher levels of salt than others, with supermarket own brands having lower levels than branded counterparts.
Researchers said a diet high in salt has been linked to numerous adverse affects on health including high blood pressure and an increased risk of stomach cancer and obesity.
