Summary
Brief summary
DHA is an omega-3 fat found in fish and fish oils and is thought to play a role in the way the brain works and develops. It has been suggested that supplementing the diet with DHA may reduce feelings of depression, while studies with young infants suggest that enriching the diet with DHA may also help improve visual development. While in the womb, the baby is supplied with DHA from the mothers circulation. The level of DHA in the mothers circulation is largely determined by the amount of DHA in the mothers diet. Australian women generally have low levels of DHA. This study will help determine whether increasing the amount of DHA in the diet improves outcome for women and their babies.
