Many people unknowingly struggle with a deficiency of iodine.
Iodine? Didn’t they talk about that in chemistry class, something about turning potatoes black?
Yes, this is true, but most Americans actually associate the word iodine with salt. Which isn’t surprising when you consider that 70%–76% of U.S. families use iodized salt to enhance their food’s flavor. Iodized salt was introduced as a general measure to make sure we could get enough iodine through our diet. A finding of this research indicates 47 of 88 able salt brands contained less than the recommended daily intake of iodine. So if you are relying on this method to get your iodine you may not be getting what you thought  and by7 default you may be iodine deficient.
