Avoiding foods that are high in sodium is key to maintaining a healthy diet. Start by putting down the saltshaker, and opting for other seasonings. You should also avoid processed foods such as soups, bouillon cubes, some salad dressings and soy sauce. Cured meats, such as bacon and salami also contain high levels of sodium, as do some cheeses and breads. You should also try to limit your consumption of brined products such as pickles and olives, which are loaded with salt.
