Iodine is a critical micronutrient in the human diet — that is, something our bodies can’t synthesize that we have to rely on food to obtain — and it’s been added to salt (in the form of potassium iodide) since 1924. Originally, iodization was adopted to reduce the incidence of goiter, an enlargement of the thyroid gland. But research since then has found that iodine also plays a crucial role in brain development, especially during gestation.
