Some Facts About Iodine And Food

Do you really need iodine in your diet?  Why is iodine added to table salt?  What foods are rich in iodine?  These are just some of the questions that you may have about iodine.  Here are some answers.

Why Is Iodine Added To Salt?

Iodine is added to salt because many people in the world do not get enough iodine from a typical diet. A deficiency of iodine is a leading cause of mental retardation and is also associated with thyroid gland problems, particularly hypothyroidism.  Because many people in the world don’t have access to or don’t consume the foods that contain iodine naturally, the addition to table salt is an inexpensive and effective way to add this important element to the diet.

What Foods Are Rich In Iodine?

Iodine is found naturally in certain seafood, especially kelp.  It is also in dairy products like cow’s milk, yogurt, and certain cheeses.  Iodine can be found in eggs.  Some vegetables grown in soil that is rich in iodine may also be a source but it would be impossible to predict how much iodine you are getting in this manner.  Table salt enriched with iodine is also an important source.

Do You Really Need Iodine In Your Diet?

Yes!  As stated before iodine deficiency is the leading cause of preventable mental retardation and leads to hypothyroidism.  A person deficient in iodine might feel tired, weak, or depressed.  They may also gain weight as a result.

In America, the average person gets plenty of iodine in their diet, nearly twice as much as is necessary for proper body function, but those who avoid dairy, seafood, and iodized salt are at increased risk of falling below the recommended daily intake amount.

  • iodine was added to salt to battle mental retardation and thyroid problems
