LOW IODINE IN VEGETARIANS

Gabe Mirkin, M.D.

A study in the Annals of Nutrition and Metabolism shows that 
vegetarians are at increased risk for iodine deficiency that causes 
low thyroid function.

 
You need to eat foods that contain iodine for your body to be able 
to make thyroid hormone. The best sources are iodized salt and 
seafood. Plants can be a good source, but only if they are grown on 
iodine-rich soil. In this study, 25 percent of vegetarians and 80 
percent of vegans had low blood levels of iodine, compared to only 
nine percent of people who eat both meat and vegetables. While 
iodized table salt is a good source of iodine, sea salt often is not.
If you don't use table salt or eat ocean fish, dairy products or 
kelp, get a blood test for iodine. If your iodine level is low, you 
need to eat more sea food or iodized salt, or take iodine pills.
