Iodine deficiency 'may lower UK children's IQ'
http://www.bbc.co.uk/news/health-22607161***SNIP
Researchers at Surrey and Bristol Universities looked at iodine levels in urine samples taken from pregnant women in south-west England.
The study showed that iodine deficiency was common - affecting two-thirds of women.
Their children went on to have slightly lower IQs at the age of eight and worse reading ability aged nine.
Dr Sarah Bath told the BBC: "We saw a three-point IQ difference between children who were born to mothers with low iodine in early pregnancy and children who were born to mothers above the cut-off."
