New research has found that pregnant women in Sweden had inadequate levels of iodine in their diets. Proper iodine nutrition is necessary for neurological development of the fetus. Iodine is an element that is involved in the production of thyroid hormones. Pregnant and breastfeeding women need about 50% more iodine in the diets, and WHO recommends a total daily iodine intake of 250 ?g/d for pregnant and lactating women. Medical evidence confirms that moderate to severe iodine deficiency during pregnancy may impair the baby’s neurological development.
