An international team of researchers from Australia, Canada, France, New Zealand, the United Kingdom and the United States looked at data on the salt content of 2124 food items in seven product categories from six companies. The companies were Burger King (known as Hungry Jack’s in Australia), Domino’s Pizza, Kentucky Fried Chicken, McDonald’s, Pizza Hut and Subway. They looked at savoury breakfast items, burgers, chicken products, pizza, salads, sandwiches and french fries.
