Non-Iodized salt is ordinary table salt that does not have iodine added to it. Many salt companies add iodine to protect against thyroid disease. But for some, iodized salt is not wanted because of the bitter taste that it can have in some recipes.
Its Many Uses
Non-iodized salt is used over iodized salts for canning pickles. It is also used for fish aquariums, as iodized salt will somehow harm the fish. For smoking meat and tanning cow's hide, non-iodized salt is also used. Rock salt is also non-iodized salt and it is used to make ice cream. Non-Iodized salt is often used in cosmetics.
Non-Iodized Salt vs Iodized Salt
Iodized salt is a good way to get the iodine that the body needs, but doesn't produce on its own. Iodine protects the body from a deficiency that could lead to thyroid problems. It is uncommon for someone from the United States to have an Iodine deficiency because the American food diet contains so many foods that have iodine.
Non-Iodized salt has the same two minerals as iodized salt --sodium and chloride.
Where to Purchase Non-Iodized Salt
Non-Iodized salt is readily available at local grocery stores, but mostly at larger chains like Walmart. It is recommend for aquariums to buy non-iodized salt at pet shops to ensure that you are getting what is best for the fish.
