Eating fish during pregnancy will help your unborn child's health and mental development, a study by Danish researchers concludes.
The project looked at 25,446 children. It found that the babies of women who ate the most fish while pregnant had a 30% better physical and mental development at 6 and 18 months of age than the babies of women who ate little or no fish.
Similarly, the children who were breastfed for 10 months or more had a 30% better physical and mental development at 6 and 18 months of age than those who were breastfed for one month or less.
Failing to breastfeed did not negate the beneficial effects of eating fish during pregnancy.
Remember to go easy, however, with oily fish such as salmon, sardines or mackerel: two portions a week is the safe limit for pregnant and breastfeeding women.
