A study by the British-based World Action on Salt and Health, or WASH, compared the salt content of 260 food products under global brands such as KFC, McDonald's, Kellogg, Nestlé, Burger King and Subway.
Not a single product surveyed had the same salt content in different markets around the world, the study found, and some displayed huge differences from one country to another.
The salt level in Canada was near the top end of the spectrum in many cases.
The data used for comparison was collected from manufacturers' own websites (Spreadsheet with all survey data).
