Do Pregnant Women Really Need to Avoid Fish?
As a mother of a 21-month old and expecting our second child later this month, I have been made aware time and time again about the importance of avoiding eating fish while pregnant, as the mercury in fish could harm my unborn child’s developing brain.
The majority of us know that fish is one of the most common sources of exposure to mercury, due to the natural erosion and industrial waste which accumulates in streams and rivers, and in some cases can make its way into oceans as well.
From the countless maternity books and websites I visited while I was pregnant with my first child, I found out that I should seriously avoid shark, king mackerel, swordfish, and tuna due to high mercury levels. Fish like tilapia, herring, and trout contained among the lowest amounts of mercury and could be eaten in moderation without fear of causing my unborn child any harm.
