To illustrate, the following are sources of sodium in the diet. Ordinary table salt is sodium chloride - 40 percent sodium by weight. When you buy prepared and packaged foods, read the labels. These products contain sodium compounds.
Some drugs contain large amounts of sodium.
Look at the ingredient list and warning statement to see if sodium is in the product. If in doubt, ask your physician or pharmacist if the drug is OK for you to use. Most spices naturally contain sodium in very small amounts. Choose fresh, frozen or canned food items without added salts. Select unsalted nuts or seeds, dried beans, peas and lentils.
