SURREY, England, May 24 (UPI) -- Pregnant women in Britain who didn't consume much fish or dairy products had children with lower IQ and reading ability than women who did, researchers said.
Study leader Margaret Rayman of the University of Surrey and colleagues at the University of Bristol analyzed mother/child pairs from the Avon Longitudinal Study of Parents and Children study by measuring urinary iodine concentration -- and creatinine to correct for urine volume -- in stored samples from 1,040 first-trimester pregnant women.
