Experts recommend pregnant women to consume two portions of fish in a week to reduce the risk of brain disorders for their babies in the womb. A recent study confirms that omega-3 fatty acid, also known as docosahexaenoic acid, found in fish, is essential for the brain to function properly.

However in Britain expected mothers are restricted from eating fish because of some harmful contamination. Jack Winkler, director of the Nutrition Policy Unit at London Metropolitan University said to telegraph. co. uk that, In 2004 , pregnant women are advised by the Food Standards Agency to consume fish, since then the research begins and it was found that women who consume more fish suffer no harm but their child's brain performance improved.

Robert McNamara, another expert from the department of psychiatry at the University of Cincinnati College of Medicine, conducted another study in which he found that boys falling in the age group of 8 and 10 were given additional docosahexaenoic acid which had improved their brain activity in attention tasks while other boys which were given placebos, an inert medicine that makes people feel better psychologically does not show any sign of improvement.
