Foods such as crackers often contain high amounts of salt. Consumers need to be aware that a high-salt diet may lead to stomach cancer, according to World Cancer Research Fund.

Cutting salt intake could reduce the number of stomach cancer cases in the UK, and “traffic light” colour labelling would help consumers to make that choice, says a leading UK cancer research charity.
