Why is iodine important in my diet during pregnancy?

Thyroid problems: The thyroid is a gland that controls every aspect of our bodies including that of the developing fetus. The thyroid needs iodine to function properly.

For Baby Brain!: The fetus will suck up the iodine it needs for thyroid function. The thing is, you would become iodine deficient with possible enlargement of the thyroid (goiter) and poor thyroid function (hypothyroid). If you were so iodine deficient that the fetus could not get enough iodine for itself there could be a risk of intellectual impairment known as cretinism.
