While seafood is generally considered a healthy food choice, there are some adverse effects associated with consuming seafood that you should be aware of. Here are a few:
Mercury contamination: Some types of seafood, such as shark, swordfish, king mackerel, and tilefish, may contain high levels of mercury. Mercury is a toxic metal that can accumulate in the body and cause health problems, especially in pregnant women and children. It is recommended to limit consumption of these types of seafood, especially for pregnant women and young children.
Allergic reactions: Seafood is one of the most common food allergens, and some people may experience allergic reactions after consuming seafood. Symptoms of a seafood allergy can range from mild to severe, and may include hives, swelling, difficulty breathing, and anaphylaxis.
Shellfish poisoning: Some types of shellfish, such as oysters, clams, and mussels, can be contaminated with harmful bacteria or toxins that can cause food poisoning. Symptoms of shellfish poisoning can include vomiting, diarrhea, and stomach cramps.
Parasite infection: Eating raw or undercooked seafood, such as sushi or sashimi, can increase the risk of parasite infection. Parasites such as tapeworms and roundworms can cause digestive problems and other health issues.
Environmental contaminants: Seafood can be exposed to environmental contaminants, such as polychlorinated biphenyls (PCBs), dioxins, and pesticides, which can accumulate in the body and cause health problems. It is recommended to choose seafood that is sustainably sourced and has been tested for contaminants.
It is important to remember that the health benefits of seafood generally outweigh the risks associated with consumption. To reduce the risk of adverse effects, it is recommended to choose a variety of seafood, and to cook seafood thoroughly to kill harmful bacteria and parasites. Additionally, pregnant women and young children should follow specific recommendations on seafood consumption to reduce the risk of mercury contamination.
