In terms of mercury levels, absolutely! Oysters are low in mercury and high in protein, which make them an ideal seafood choice for pregnant women. Oysters are especially rich in Vitamin B6 and B12 and help to prevent anemia iand neural tube defects in the mother and baby respectively. They are also a great source of the mineral zinc that helps in maintaining the immunity and cell growth of the mother. Furthermore, the omega 3, magnesium, and potassium help reduce inflammation and lower the risk of heartburn. However, the risks involved with oysters are just as many. Sometimes, they might carry the bacteria Vibrio vulnificus that causes food poisoning, and the Listeria bacteria that can lead to miscarriage, premature birth, and stillbirth. To effectively avoid these downsides, it is important to eat oysters that are fully cooked and in moderation.
