Table salt

Table salt is the white granulated salt seen in most saltshakers. Table salt is typically mined from underground deposits. It's then processed to remove other minerals. Table salt is commonly fortified with iodine, which is important for thyroid health.

Kosher salt

Kosher salt is a granular salt traditionally used in the koshering process to cure meats. It's long been a favorite with chefs. When used as a finishing salt, kosher salt adds a crunchy texture to dishes.

Sea salt

Sea salt is produced by evaporation of ocean water or water from saltwater lakes. It's less processed than table salt and retains trace minerals. These minerals add flavor and color. Sea salt is available as fine grains or crystals.

Sea salt is often promoted as a healthier alternative to table salt. But they contain comparable amounts of sodium by weight.

Seasoned salt

Seasoned salt is salt mixed with herbs and spices. Examples include garlic salt, onion salt and celery salt. Seasoned salt generally has slightly less sodium than does table salt.

Salt substitute

Salt substitute is made by replacing sodium with potassium, magnesium or another mineral. Doctors and dietitians sometimes recommend salt substitutes to people following a sodium-restricted diet.

However, salt substitutes aren't appropriate for everyone. If you need to watch your potassium, check with your doctor before trying salt substitutes.
