Beyond fast food: It’s not just the usual fast food villains that are adding to the mounting excess sodium woes. Seemingly innocent, otherwise healthful foods can be part of the problem. One cup of commercially prepared vegetable broth can provide 940 mg of sodium, and one cup of canned beans can rack up 770 mg. Two tablespoons of Italian dressing on your salad adds 486 mg, and 1 cup of regular pasta sauce could include 1100 mg. (See chart for other foods and low-sodium
Not all brands the same: Sodium levels vary widely across brands for the same product. Some brands have 50–200% more sodium than their competitors. The “same” product marketed in different countries also will have different sodium levels. The U.S. version of Nabisco’s Premium Saltines has 40% more sodium per serving than its Canadian counterpart.2
Perfect for profit: Why are processed foods so loaded up with sodium? Salt heightens flavors, reduces bitterness, and enhances sweetness. Salt is perfect for processed foods. It is cheap. It keeps foods from becoming discolored, and it extends shelf life. It binds water and makes foods weigh more, so you pay more for a heavier package.3
What people want: When food companies do consumer research, they find that unless their food products are salty enough, people do not like the way they taste. As consumers have gotten used to higher and higher levels of salt in their foods, their taste buds have lost their ability to taste the subtle flavors found in natural foods. Once your ability to taste deteriorates to that point, all foods taste too bland unless they are highly salted. It is no wonder that a growing population whose taste buds are damaged demands foods that contain lots of salt.
