When Moms Eat Fish Fish every two weeks improves vision Mothers who eat fatty fish during their pregnancy or while nursing appear to speed their babies' visual development, according to new research. Fatty fishes include tuna, salmon, mackerel and bluefish. These fish supply the richest source of a fatty acid that's important for brain development. Pregnant women and new mothers don't need to eat fish every night to improve their children's eyesight. Eating fish just once every two weeks does the trick, Ananova reports.
Fish is beneficial to more than just babies, too.
A previous HealthScout story adds that eating fish improves brain function in women. However, some fish can pose health hazards. While fish is highly nutritious, some types can contain small amounts of environmental toxins. Another HealthScout story says that shark, swordfish, king mackerel and tilefish have particularly high concentrations of methyl mercury . Surprisingly, farmed fish may be riskier than ocean fish , another story explains.
