According to American Heart Association: The "Salty Six"
1) Breads & Rolls (230 mg per piece)
2) Cold cuts and cured meat (1 g per pre-packaged turkey)
3) Pizza (760 mg per slice)
4) Chicken (amount depends on type of processing)
5) Soup (940 mg per cup)
6) Sandwiches (Ketchup, mustard,..) (1.5 g per sandwich)
Problem with this list is that it is not memorable! And, the items in the list are not mutually exclusive. For example, a sandwich contains breads/rolls, cold cut/cured meat or chicken. Thus, 1, 2 and 4 are actually the 6!
