A study of more than 1,000 pregnant women found those who consumed lower amounts of iodine, which is absorbed from food and found in milk, dairy products and fish, were more likely to have children with lower IQs and reading abilities.
Iodine is essential for producing hormones made by the thyroid gland, which has a direct effect on the development of the foetal brain.
The study by researchers at Bristol and Surrey universities found two thirds of the 1,040 pregnant women they tested were iodine deficient. These women were more likely to have children with lower IQs, and it was found the lower the iodine the lower the IQ and reading ability.
Professor Margaret Rayman of the University of Surrey, who led the study, said: \”Our results clearly show the importance of adequate iodine status during early pregnancy, and emphasise the risk that iodine deficiency can pose to the developing infant, even in a country classified as only mildly iodine deficient.\”
Researchers have said pregnant women should ensure they get enough iodine by eating dairy products and fish, as well as drinking milk. But they warned against kelp supplements, as they can have ‘excessive levels’ of iodine.
Iodine deficieny in the mother leads to goitre, in the child to cretinism. Been known for a long time this. The solution is to stick iodine into hte salt that the population eats (sea salt has it already, mined salt may not).
And what have the doctors been terlling everyone? Eat less salt, where the iodine the pregnant women need is.
