Question

Quizplus · Accepted Answer

Insufficient intake of iodine from foods is the most common cause of iodine deficiency. Iodine is found in a limited number of foods, and if they are not regularly consumed or if the soil where the food is grown is deficient in iodine, it can lead to a deficient intake. Over-consumption of other trace elements or anti-thyroid substances and pituitary deficiencies of thyroid-stimulating hormone are not common causes of iodine deficiency.
