• Oily fish - is good for you and your baby but it can contain environmental pollutants. Have no more than two portions of oily fish a week such as mackerel, sardines and trout so you get all the benefits of omega-3 fatty acids, but also cut the risk from the pollutants. Limit tuna to no more than two tuna steaks a week or four medium-size cans of tuna a week. Avoid shark, swordfish and marlin altogether because of the high levels of mercury in these fish, which could harm your baby's developing nervous system. |
