Eating fish during your pregnancy can enhance fetal brain development.
In a study, the babies of mothers who ate fish regularly showed signs of having better memories and levels of concentration than other infants.
However, babies of mothers who had consumed shark, swordfish and other fish which contained high levels of mercury appeared to have slightly reduced mental ability.
The researchers at Harvard University advised that the value of continuing intake of omega-3 fatty acids should not be underestimated but that pregnant women should avoid mercury-heavy fish and keep their intake of all fish to about two servings per week.
