Iodized salt is table salt containing a small quantity of an iodine-containing salt, intended to prevent iodine deficiency.<ref name="ref1" /> Sea salt is produced from the evaporation of seawater and is used in cooking and food preservation. Both salts consist primarily of sodium chloride, but their production methods, mineral content, and applications differ.

By weight, both salt types contain about 40% sodium.<ref name="ref2" /><ref name="ref3" /> A common misconception is that sea salt has less sodium, which arises because coarse sea salt crystals take up more volume than fine table salt, resulting in less sodium in a measurement like a teaspoon.<ref name="ref4" />

! Category !! Iodized Salt !! Sea Salt
|-
| '''Source''' || Mined from underground salt deposits.<ref name="ref5" /> || Harvested from evaporated seawater.
|-
| '''Processing''' || Heavily processed to remove minerals; additives like anti-caking agents are included.<ref name="ref4" /> || Minimal processing; may be refined or unrefined. Unrefined salt retains impurities and minerals.<ref name="ref5" />
|-
| '''Iodine Content''' || Fortified with iodine (commonly potassium iodate) to prevent deficiency.<ref name="ref1" /> || Contains only negligible, trace amounts of natural iodine.
|-
| '''Trace Minerals''' || Most trace minerals are removed during processing.<ref name="ref2" /> || Retains trace minerals like magnesium, potassium, and calcium from seawater.
|-
| '''Texture''' || Typically fine, uniform crystals that dissolve quickly. || Varies from fine to coarse, irregular crystals, providing a crunchy texture.
|-
| '''Common Uses''' || General-purpose cooking and baking where even distribution is needed; primary dietary source of iodine for many. || Used as a finishing salt for texture and in specific culinary applications like seasoning meats.

=== Health considerations ===
Iodine is an essential micronutrient necessary for the thyroid to produce hormones that regulate metabolism. A deficiency can lead to conditions such as goiter (an enlarged thyroid gland) and hypothyroidism. It is also a leading preventable cause of intellectual and developmental disabilities worldwide. The fortification of table salt with iodine, which began in the U.S. in the 1920s, has been an effective public health measure to combat these issues.

Sea salt is often marketed as a healthier alternative due to its natural origin and the presence of trace minerals. However, the quantities of these minerals—such as potassium, magnesium, and calcium—are generally too small to offer significant nutritional benefits, which are more easily obtained from a balanced diet. Choosing<ref name="ref2" /> unfortified sea salt over iodized salt may increase the risk of iodine deficiency for individuals who do not consume other iodine-rich foods like seafood and dairy products.

==<ref name="ref2" />= Production and processing ===
Iodized salt typically originates from rock salt mined from ancient underground seabeds. The<ref name="ref5" /> raw salt is heavily refined to remove impurities and other minerals, resulting in nearly pure sodium chloride. During this process, an iodine source such as potassium iodate is added, along with anti-caking agents to ensure a fine, free-flowing product.

Sea<ref name="ref1" /><ref name="ref5" /> salt production relies on the solar or wind evaporation of seawater in large, shallow ponds. This method is less industrial and preserves more of the ocean's natural mineral content. The resulting salt crystals can vary in size, color, and flavor depending on the specific water source and harvesting techniques used.
