Most of the salt in the American diet comes from manufactured foods like canned and dried soups, sauces, and frozen and canned meals, although salt-cured foods are widely eaten in some areas. Limiting salt is also a concern for preventing hypertension and stroke. Try herbs and spices as a flavorful alternative. Do not eat food which, as a result of long storage at ambient temperatures, is liable to contamination with mycotoxins. Foods contaminated with aflatoxins and other fungal microorganisms probably increase the risk of primary liver cancer.
