1. Fast Food
The thyroid gland uses iodine from our diets to create the hormones T3 and T4. In fact, the thyroid is the only organ that uses iodine. There are lots of reasons to avoid fast food, but when it comes to thyroid disease, the fact is that this food contains a ton of salt but very little iodine.
At home, we get a lot of our daily iodine from iodized table salt, but there is no requirement for fast food restaurants to use iodized salt in their food. Studies confirm that fast food meals net you very little helpful iodine for all the sodium you’ll consume.
