A new statement by the Academy of Pediatrics shows that almost one in three women has an iodine deficiency. Pediatricians are now recommending mothers add iodine supplements to their diet, the Medical Daily reported.

Iodine produces the thyroid hormone, which aids in the development of the brain in newborn babies. According to the American Academy of Pediatrics, it comes from iodized salt, which is not normally found in the processed foods. The Nutrition Journal reports that iodine can also be found in dairy products. 

Researchers discovered that only 15 percent of pregnant and breastfeeding women currently take iodine supplements.

"It may be that most people don't appreciate the importance of adequate iodine in the diet for normal fetal development and that the women with marginal levels have no indication of their iodine status," said Dr. Jerome Paulson, medical director at the Children's National Health System.

The report also says that severe iodine deficiency can stunt physical and mental growth, proving that supplements are a key component to giving birth to healthy babies. Iodine is also contributed to protecting babies from environmental hazards.

The Academy of Pediatrics recommends pregnant women take a minimum of 150 micrograms of iodide, and use iodized table salt.
