6 Types of Fish to Avoid or Limit Due to High Mercury Levels
SharkWhy to Avoid: Sharks are top predators, and mercury accumulates in their bodies over time (a process called bioaccumulation). Health Risks: Mercury can damage the nervous system, particularly in young children and unborn babies.
Swordfish
Why to Avoid: Another large predator with high mercury levels due to their long lifespan. Health Risks: Mercury can cause neurological issues and impair brain development in children.
King Mackerel
Why to Avoid: King mackerel has one of the highest mercury concentrations among fish. Health Risks: Regular consumption can lead to mercury poisoning, which affects the kidneys and nervous system.
Tilefish (from the Gulf of Mexico)Why to Avoid: Tilefish ranks high in mercury and should be avoided, especially by pregnant women. Health Risks: High mercury levels can lead to developmental delays in children and health complications in adults.
Tuna (Bigeye and Ahi)
Why to Avoid: While canned light tuna has lower mercury levels, bigeye and ahi tuna are high in mercury. Health Risks: Overconsumption can harm brain function and increase toxicity in the body.
Orange Roughy
Why to Avoid: This fish lives for a long time, allowing mercury and other contaminants to accumulate. Health Risks: Mercury toxicity can lead to tremors, memory issues, and kidney damage.
Why Mercury is Dangerous For Pregnant Women: Mercury crosses the placenta and can harm fetal brain and nervous system development. For Children: It can interfere with brain development, leading to learning difficulties and delayed milestones. For Adults: High mercury exposure can cause neurological symptoms, kidney damage, and cardiovascular issues.Safe Fish Alternatives Low-Mercury Fish: Salmon Sardines Cod Tilapia Anchovies These fish are rich in omega-3 fatty acids, which are beneficial for heart and brain health.
Tips for Safe Fish Consumption Moderation: Limit fish high in mercury to occasional consumption (if at all). Choose Smaller Fish: Smaller fish generally contain less mercury. Check Advisories: Follow local fish advisories for safety regarding mercury levels in locally caught fish. Diversify Seafood: Rotate your seafood choices to minimize the risk of overexposure to mercury.
