Here's why:
* Predatory fish like sharks and swordfish accumulate mercury: They sit at the top of the food chain and consume other fish that have already accumulated mercury in their bodies. This means they have a much higher concentration of mercury than smaller fish lower on the food chain.
* Mercury is a neurotoxin: It can damage the nervous system, particularly in developing fetuses and young children.
* Methylmercury is especially dangerous: This is the organic form of mercury, and it's easily absorbed by the body.
It's important to note:
* Not all shark and swordfish are equally contaminated: The level of mercury can vary depending on the species, age, and location where the fish was caught.
* Smaller fish generally have lower mercury levels: If you're concerned about mercury, choose smaller fish species like tuna or salmon.
* Limit your intake of shark and swordfish: The FDA and EPA recommend limiting consumption of these fish, particularly for pregnant women, breastfeeding mothers, and young children.
If you have concerns about mercury poisoning, talk to your doctor.
