mercury can pass through the placenta and into the developing baby… mercury can also pass through breast milk
Congratulations on your journey to motherhood! As an expectant mother, it’s important to pay attention to your diet and make choices that promote the health and well-being of both you and your baby. One crucial aspect of pregnancy nutrition is avoiding foods that are high in mercury. In this article, we will explore why foods containing mercury are harmful during pregnancy and provide guidance on making safe choices for you and your little one.
What is Mercury?
Mercury is a naturally occurring silvery metal that exists in various forms, including elemental mercury, inorganic mercury compounds, and organic mercury compounds. While elemental mercury is liquid at room temperature, it’s the organic mercury compounds that pose the greatest risk to pregnant women and their developing babies. Methylmercury, a type of organic mercury, is of particular concern.
Mercury Contamination
Mercury is released into the environment through natural processes like evaporation from water bodies, volcanic emissions, and degassing from the earth’s crust. Human activities such as mining, burning fossil fuels, and industrial processes also contribute to the release of mercury into the environment. This mercury finds its way into water bodies like oceans, streams, and lakes, where fish and other animals consume it. As a result, mercury accumulates in their bodies. When pregnant women consume these contaminated fish, the mercury can pass through the placenta and into the developing baby. Additionally, mercury can also pass through breast milk, although in smaller amounts.
Health Risks for Pregnant Women and Babies
Exposure to high levels of mercury during pregnancy can have severe consequences for both the mother and the baby. Here are some reasons why foods high in mercury should be avoided:
- Nervous System Development: Mercury is highly toxic to the developing nervous system, and babies are particularly vulnerable to its harmful effects. High mercury exposure during pregnancy has been associated with developmental delays, learning disabilities, and impaired cognitive function in children.
- Organ Damage: Mercury can cause damage to the developing organs of the foetus, including the brain, kidneys, and lungs. These organs are crucial for the overall health and well-being of the baby.
- Pregnancy Complications: Studies have shown that exposure to mercury during pregnancy may increase the risk of complications such as spontaneous abortion and fertility issues. The ingestion of methylmercury has been linked to abnormal menstrual cycles and can lead to difficulties in achieving a healthy pregnancy.
Summary
Being mindful of the foods you consume during pregnancy is crucial for the health of both you and your baby. Foods high in mercury, particularly certain types of fish, pose significant risks to the developing fetus. By avoiding these high-mercury foods and opting for low-mercury alternatives, you can ensure a safe and healthy pregnancy.
Safe Choices
By choosing these low-mercury seafood options, you can still benefit from the essential nutrients they provide, such as omega-3 fatty acids, which support your baby’s brain and eye development:
