Hey there! If you’re a woman of childbearing age, you might be wondering which fish to pick for those awesome omega-3 fatty acids while avoiding any mercury-related health risks. Omega-3s, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are known to lower the risk of hypertension, atherosclerosis, type 2 diabetes, and various inflammatory disorders. DHA is particularly important for fetal brain and eye development and can even help reduce the chances of premature birth.
Fish like mackerel, herring, salmon, halibut, and tuna are packed with EPA and DHA, but here’s the catch: some seafood can have high levels of methylmercury (meHg), which is toxic and can overshadow the health benefits of fish. There were some scary cases of mercury poisoning in places like Japan and Iraq decades ago, leading to serious health issues in infants and even in some mothers.
Studies show that meHg can affect reproductive health, contributing to problems like decreased sperm quality and higher rates of miscarriage. In fact, couples facing infertility often show higher mercury levels compared to their fertile counterparts. Plus, there’s evidence suggesting that mercury exposure can lead to lower intelligence and learning disabilities in children.
Methylmercury enters our waterways primarily from industrial pollution and can accumulate in fish as it moves up the food chain. When we eat fish containing meHg, our bodies absorb about 95% of it, which can linger for months. This is especially concerning because mercury can show up in breast milk too. The National Academy of Sciences has set a guideline for maximum daily intake of meHg, but some experts suggest even lower limits, particularly for pregnant women.
To play it safe, the FDA recommends avoiding certain fish like shark, swordfish, king mackerel, and tilefish if you’re planning to get pregnant. And let’s not forget about the environmental impact—by skipping these fish, you’re also helping protect endangered species and ecosystem health.
Moreover, many fish caught in Northern California waters should be avoided due to mercury and PCB contamination.
