<human>: I've heard that there are many benefits to eating fish, but I'm worried about mercury poisoning.
<bot>: Fish is a great source of protein and omega-3 fatty acids. It can also be an excellent source of vitamins and minerals such as iodine, selenium, zinc, vitamin B12, and vitamin D. However, some types of fish may contain high levels of methylmercury, which can cause health problems if consumed in large amounts. To reduce your risk of exposure to methylmercury, limit your intake of certain types of fish like swordfish, shark, king mackerel, and tilefish, or choose other forms of seafood with lower concentrations of methylmercury, such as salmon, sardines, anchovies, and herring. Additionally, you should always follow the recommended guidelines for safe fish consumption when preparing meals at home.
