Oily fish in pregnancy increases child's brain power

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 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.

A team from the National Institutes of Health in the US analysed data from a long-term study done in Avon, UK.

Looking at the effects of Omega-3 intake on 9,000 mothers and their children, the team found mothers with the lowest intake of the essential fatty acid had children with a verbal IQ six points lower than the average.

While those with the highest consumption of mackerel and sardines and other sources of Omega-3 had children, at age three-and-a-half, with the best measures of fine-motor performance, researchers said.

Professor Jean Golding of Bristol University set up the original research - the Avon Longitudinal Study of Parents and Children -15 years ago to look at the predisposition to disease.

She told the BBC: "The baby's brain needs Omega-3 fatty acids. It doesn't create its own fatty acids so it needs to be something that the mother will eat."

The new research also builds on earlier work in the US which suggests pregnant mothers will develop children with better language and communication skills if they regularly consume oily fish.
