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.
