Deficiency Of Iodine During Pregnancy Reduces IQ Of Future Child.
Mild to abate iodine deficiency during pregnancy may have a antagonistic long-term impact on children's thought development, British researchers report. Low levels of the so-called "trace element" in an watchful mother's diet appear to put her child at risk of poorer verbal and reading skills during the preteen years, the on authors found. Pregnant women can boost their iodine levels by eating enough dairy products and seafood, the researchers suggested. The finding, published online May 22, 2013 in The Lancet, stems from an critique of inartistically 1000 mother-child pairs who were tracked until the sprog reached the age of 9 years.

And "Our results clearly show the rank of adequate iodine status during early pregnancy, and emphasize the risk that iodine deficiency can ostentation to the developing infant," study lead author Margaret Rayman, of the University of Surrey in Guildford, England, said in a gazette news release. The study authors explained that iodine is depreciative to the thyroid gland's hormone production process, which is known to have an impact on fetal perception development.

According to the World Health Organization, iodine "sufficiency" is defined as having a so-called iodine-to-creatinine proportion of 150 micrograms per gram (mcg/g) or more; those with a ratio falling below 150 mcg/g are deemed to be iodine "deficient". By examining first-trimester urine experience facts collected by a long-term study of parents and children based in Bristol, England, the study authors found that just over two-thirds of the mothers had been iodine-deficient while pregnant.

After adjusting for other factors (such as breast-feeding representation and parental education), the researchers found that iodine deficiency during pregnancy raised the child's hazard for having a downgrade verbal IQ, and poorer reading accuracy and comprehension by the time they turned 8 or 9. What's more, the more iodine levels dropped during pregnancy, the earlier the child's performance in terms of IQ and reading ability, the scrutiny authors noted.

Study co-author and registered dietitian Sarah Bath agreed that "pregnant women and those planning a pregnancy should safeguard adequate iodine intake". She suggested in the tidings release that "good dietary sources are milk, dairy products and fish. Kelp supplements should be avoided as they may have unconscionable levels of iodine" bonuses. The US National Institutes of Health states that 3 ounces of baked cod contains approximately 99 mcg of iodine, 1 cup of wold low-fat yogurt contains about 75 mcg, and 1 cup of reduced-fat withdraw has an estimated 56 mcg.
