Recently, a new study in the United Kingdom found that supplementing iodine before pregnancy and during pregnancy can help improve baby IQ and health.
Pregnancy attention to iodine baby high IQ
According to the "Life Times" report, Professor Kate Dr. Zhu Li and his colleagues at the University of Birmingham in the United Kingdom analyzed a number of research reports and expert opinions. Through mathematical modeling, iodine supplementation during pregnancy can be used to transform brain development into IQ scores. The calculated result is that the mother's iodine supplement during pregnancy is equivalent to a 1.22 increase in childhood IQ. The study also found that in 32 iodine-deficient countries, approximately 1.9 billion people lived and 241 million school-age children (6 to 12 years old) lived. Iodine supplementation during pregnancy is of great significance to the improvement of the quality of the population.
Dr. Zhu Li said that severe iodine deficiency during pregnancy can lead to mental disorders and developmental retardation in children with low IQ. After growing up, due to the low level of education, their income is also bound to be seriously affected. International organizations such as the World Health Organization and the European Food Safety Authority recommend that pregnant women and nursing women should supplement iodine daily. In iodine-deficient countries, all women who are pregnant, breast-feeding or preparing to get pregnant should be supplemented with iodine every day. They can often eat iodine-rich foods such as dairy products and seafood. In iodine-deficient areas, you can take iodine supplements or supplements under the guidance of a doctor.
Expectant mothers to make up for how much iodine during pregnancy
According to the latest 2013 edition of the “Daily Dietary Reference Intake of Chinese Residentsâ€, 230 μg (μg) is recommended daily during pregnancy, and 240 μg per day during breast-feeding, and it is safe to consume less than 600 μg per day. The average adult recommended amount is only 120μg. The implication is that mothers need iodine twice as much as the general population to complete fetal and infant iodine needs.
The World Health Organization recommends that pregnant women should receive 150 μg of iodine supplements daily if iodine intake is lower than 250 μg per day (i.e., the urine concentration of iodine in urine is less than 150 μg/L).
Iodized salt does not meet pregnancy needs
In China's inland areas, iodized salt is the main source of iodine in foods, and the iodized salt on the market is for the general population, not for expectant mothers and lactating mothers, and is not enough to provide for pregnancy and lactation. Extra iodine.
How to replenish iodine during pregnancy
How should pregnant mothers supplement iodine during pregnancy? Liu Changwei, a nutrition doctor at Nanjing Children's Hospital, said that expectant mothers can properly consume iodine-containing foods including kelp, marine fish, seaweed, shellfish and other seafood with high iodine content. However, it has been suggested that algae (seaweed, seagrass, seaweed) or algae products should not be used as supplemental iodine during pregnancy because their iodine content is very unstable and may contain heavy metal mercury contamination. The iodine content of oysters in seafood is also relatively high, but be careful to avoid bacterial or viral infections.
Therefore, it is advisable to take 150 μg of iodine supplements daily or take special nutritional supplements designed specifically for pregnant women. Many mothers worry about how excessive iodine supplementation leads to hyperthyroidism. In fact, these concerns are superfluous. According to the recommended amount, daily intake of 600 μg of iodine is safe.
