Iodized Salt vs. Sea Salt: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 4, 2024
Iodized salt is table salt mixed with a minute amount of various iodine-containing salts, while sea salt is made by evaporating seawater and retains trace minerals.

Key Differences

Iodized salt is produced by adding iodine to regular table salt, typically to prevent iodine deficiency. Sea salt is made by evaporating seawater, which leaves behind various minerals in addition to sodium chloride.
Iodized salt often has a fine, uniform texture and is usually bright white. Sea salt, on the other hand, can vary in color and texture, with some varieties being coarser and less refined.
The taste of iodized salt is generally consistent and is a staple in everyday cooking. Sea salt's flavor can vary based on its mineral content and is often preferred for finishing dishes due to its unique taste and texture.
Iodized salt provides a necessary nutrient, iodine, which is essential for thyroid function. Sea salt contains trace minerals like magnesium, calcium, and potassium, which can contribute to its taste and nutritional value.
Iodized salt is widely available and generally less expensive than sea salt. Sea salt, often considered a gourmet ingredient, can be more expensive and is available in various grades and textures for different culinary uses.
