A look at the saltiest foods as FDA prepares to issue sodium guidelines

The Food and Drug Administration is preparing voluntary guidelines that will encourage the food industry to make their foods less salty in an effort to reduce heart attacks and strokes. Most of that sodium isn't from the salt shaker, but is hidden inside common processed foods and restaurant meals.

Some of the saltiest foods , based on 2010 data from the Agriculture Department:

— Burgers and sandwiches, which provide 21 per cent of Americans' total sodium intake.

— Rice, pasta and grain dishes, 7 per cent.

— Meat, poultry and seafood dishes, 6 per cent.

— Pizza, 6 per cent.

— Dairy, 5 per cent.

— Soups, 4 per cent.

— Condiments, gravies, spreads and salad dressings, 4 per cent.
