Government agency for hazard evaluation - Pregnancy: Consuming fish may affect brain development.
Mothers-to-be and nursing women are encouraged to steer clear of specific types of fish by the Federal Institute for Risk Assessment (BfR). This is due to the presence of a compound known as methylmercury (MeHg) that naturally builds up in certain species such as fish, shellfish, crabs, and octopus.
Whilst the general population is unlikely to experience negative effects, the substance has been shown to interfere with the neurological development of unborn and breastfed infants, the institute cautioned.
Speaking on the topic, BfR President Andreas Hensel explained that limiting the intake of methylmercury is crucial, especially for pregnant and breastfeeding women. Citing scientific evidence, Hensel said, "Research suggests that methylmercury can hinder neurological development."
The institute identified large, older predatory fish like shark, swordfish, tuna, and redfish as containing high levels of methylmercury. Their findings were derived from a study examining the concentration of substances in different types of food.
Pregnancy and the Importance of Fish
MeHg is produced when microbes convert inorganic mercury compounds into organic forms. Humans can absorb the substance from these organic compounds through the food chain. While it's essential to understand the risks, it's equally crucial to consider the beneficial components found in fish. These include vitamins, trace elements, and certain polyunsaturated fatty acids.
