What Is Iodized Salt? How to Use Iodized Table Salt

Iodized salt is a mix of salt and iodine. Salt manufacturers add iodine to salt by mixing table salt with iodine compounds such as potassium iodate, potassium iodide, sodium iodate, or sodium iodide. Adding iodine to salt is a way to address iodine deficiency, a public health issue affecting almost two billion people worldwide.

Iodized salt is different from other types of salt because it contains iodine, but it tastes the same as non-iodized salt. Iodine is typically an additive in table salt, not specialty salts such as sea salt, Himalayan salt, and kosher salt. You can use iodized salt as a seasoning or baking ingredient as you would regular table salt.

Iodine is a micronutrient present in the earth and in food. Seafood, dairy products, eggs, and certain vegetables are high in iodine content. The human thyroid gland uses iodine to produce thyroid hormones, which regulate metabolism and repair tissue. Not consuming enough iodine can cause various health problems like hypothyroidism, leading to a goiter or an enlarged thyroid.

Adding iodized salt to your diet can help address an iodine deficiency and is generally safe to consume. However, there are additional factors to consider when consuming iodized salt:

1. 1. Health benefits: Iodized salt promotes the production of hormones that can help regulate metabolism, slow heart rate, and promote a healthy pregnancy.
2. 2. Dietary iodine: You can meet the recommended daily amounts of iodine by consuming natural sources of iodine, which include seaweed, cod, whole-wheat bread, and milk.
3. 3. Recommended intake: Too much iodine can also lead to thyroid issues. The maximum recommended daily iodine intake in adults is 150 micrograms per day, according to the US Food and Drug Administration.
4. 4. Iodine supplements: Too much sodium can lead to high blood pressure. If your diet involves reducing your salt intake, you can also take iodine supplements in pill form.
