Eating oily fish and seeds in pregnancy can boost children’s future brain power and social skills, research suggests. A study of 9,000 mothers and children in Avon suggested those who consumed less of the essential fatty acid Omega-3 had children with lower IQs. These children also had poorer motor skills and hand-to-eye co-ordination, research in the Economist said. The Food Standards Agency says pregnant women should consume only one or two portions of oily fish a week. A team from the National Institutes of Health in the US analysed data from a long-term study done in Avon, UK.
