Sugar in Iodized Salt?

Unfortunately, the answer is yes. Thanks to a client who is an avid label reader, we discovered that iodized salt, even the healthier versions such as Hain Iodized Sea Salt, contains dextrose, a corn sugar. Dextrose is not an anti-caking agent, so why do they add it to sea salt? They say it is to "stabilize" the iodine. We think it is to mask the taste of the iodine.

It is critical that you get sufficient amounts of iodine. So for those of you who are corn-sensitive, what are your options?

Iodine was added to salt in the 1920's to benefit the thyroid and prevent goiters. Since salt is the one mineral everyone uses, U.S. public officials decided it would be the best delivery system. One teaspoon of iodized salt daily usually provides all the iodine you need. Development of iodine deficiency is rarely an issue because of this decision. In addition, landlocked regions receive produce grown in coastal areas where soil is rich in iodine.

For adults and teens, I recommend a daily intake of 150 micrograms (mcg.). For children, daily intake is 70 micrograms. Non-Iodized Sea Salt and Kosher Salt do not supply enough iodine. Although, I prefer you always use sea salt because it does not have as detrimental effect on blood pressure as does bleached rock salt.

Most of you who take multivitamins/minerals have enough iodine to prevent goiters. Check the label to make sure. For those of you who do not take a multi, or if your multi does not contain iodine, buy a separate bottle of iodine in pill form or get one or more of the following sources on a regular basis: kelp, sea vegetables, seafood, drinking water, and small amounts in eggs. The iodine content of fruits and vegetables is dependent upon soil content.

Note: given the fact that most Americans consume on average more than twice the daily recommended amount of salt (3500 mg per day instead of the recommended 2300 mg or less, and 1500 mg or less for hypertensive individuals), getting your iodine from non-salt sources like your multivitamin is a good thing.
