I've heard that there are many benefits to eating fish, but I'm worried about mercury poisoning.

Fish is an excellent source of essential nutrients and omega-3 fatty acids. It’s also a great source of protein and low in saturated fat. However, some types of fish contain high levels of methylmercury, which can be harmful if eaten in large amounts. The US Food and Drug Administration recommends limiting your intake of certain types of fish, such as swordfish, shark, king mackerel, tilefish, and albacore tuna, because they tend to have the highest levels of mercury. You should also limit your consumption of larger predatory fish like marlin and tuna, since these species often contain higher concentrations of mercury than smaller species.
