Bad news for sandwich lovers. According to the latest government analysis, we're all eating too much salt and our beloved midday sammies are the culprits. Part of the lunch food's problem is its popularity: 49 percent of adults eat at least one sandwich on a typical day, according to the 2009-2010 What We Eat in America survey. And sandwiches account for 20 percent of a typical day's sodium intake.
For most sandwiches, participants reported the various components of their sandwich (such as bread and fillings) individually. Those components were then coded separately with multiple food codes that were linked to indicate they were eaten together as a sandwich.
