Is Fish a Big No-No For Expectant Mommies?

In the past, everything that was rich in protein was encouraged as part of a pregnant woman’s diet. After all, protein is a nutrient that builds the baby’s cells – without it, there would be very little room for growth and development. Fish was considered to be the best sources of protein, and it still is. However, expectant mothers today are being warned against the consumption of fish. Why? 

Fish, especially deep-sea fish, are quite likely to contain large amounts of mercury. While it may not be toxic to the fish, or to the woman, the mercury content of edible deep-sea fish can affect the baby, and in worst scenarios, even cause a miscarriage.

Mercury is a metal that is a known estrogen antagonist. This means it works against the effects of estrogen in the body. Estrogen is a much-needed hormone that sustains pregnancy. It is what stimulates the woman’s body to adapt to changes in order to keep the pregnancy going until it is term. High accumulations of mercury in a pregnant woman’s body may antagonize the functions of estrogen and in doing so, cause a miscarriage. It may also be the culprit behind fetal malformations, stillbirth and preterm labor.

So, should all types of fish be avoided? Moderate amount of salmon is safe, but tuna and mackerel may not be a good idea. Any pregnant woman can obtain high quality protein from eggs, lean meat, tofu, nuts, grains and various other legumes.
