You've probably always been told not to eat fish during pregnancy, but new findings may change that rule.

According to a new study published in the journal Pediatric Research, eating fish three times a week during your third trimester is actually very good for your baby.

The old adage that fish during pregnancy will be harmful to the fetus has changed a bit (as have many things about pregnancy is recent years.).

Now doctors say you can and should eat fatty fish, especially during the last trimester of your pregnancy.

The reason?

Well findings show that eating the fatty fish (those with high levels of omega-3 fatty acids) results in better eye sight and brain development in the newborn babies.

Fish like salmon, sardines and mackerel are recommended at least twice a week to get this result.

Of course the health benefits to omega-3's have been known for a while. Helping to improve your heart, joint and brain function...and apparently your baby's too.

Fish also contain vitamins D and E which are essential to development, so overall they are a very healthy meal choice.

The research did show the best time to eat fish for pregnant women as the third trimester, when harmful mercury in fish would be least likely to effect the unborn child negatively.

Of course moderation with fish during pregnancy is still important, so keeping fish to two or three meals a week is ideal.
