The need for iodine during pregnancy
In pregnancy, iodine helps your baby’s brain and nervous system develop. “When a pregnant woman doesn’t have enough iodine in her body, her child may suffer irreversible brain damage and could have an IQ that is 10 to 15 points lower than it would otherwise be. An educated guess is that iodine deficiency results in a needless loss of more than 1 billion IQ points around the world,” explains Nicholas Kristoff in a column for The New York Times.
A lack of iodine during pregnancy has also been linked with an increased risk of miscarriage, preterm delivery, and stillbirth.
According to the WHO, Pregnant women need about 66% more iodine than non-pregnant women. It is recommended that a pregnant woman has about 220 micrograms (mcg) of iodine per day.
Food sources of iodine during preganncy
In general, foods from the sea contain the most iodine, followed by animal foods, and then plant foods. Vegetables like artichokes, potatoe and spinach and fruits like pineapple, coconut, strawberries, rhubarb, mango, dates and apricots are also reliable sources of iodine.
