What’s the story with iodine?

Iodine is an essential nutrient, but one that many have forgotten about despite the fact that iodine deficiency was a major public health crisis all throughout human history until 1924.

Iodized salt was the solution to iodine deficiency. But, since the FDA advised everyone to cut back salt intake, iodine deficiency and even goiters (enlarged thyroid glands due to lack of iodine) are making a comeback along with weight gain, fatigue, thinning hair, high blood pressure and other health problems, yet the solution is so simple.
