They are also low in mercury.<\/p>\n<p>Mercury is a heavy metal that can harm your health if eaten in large amounts. It is found in the environment, including oceans and freshwater, so fish contain it too.<\/p>\n<p>Mercury levels in fish depend on where they live and what they eat, as well as their species, age, and size. Some fish have more mercury than others.<\/p>\n<p>A can (92 grams) of Atlantic sardines contains:<\/p>\n<p>Omega-3 fatty acids: 0.9 g<\/p>\n<p>Experts recommend eating fish regularly despite its mercury content. This is because the benefits outweigh the risks. Try choosing fish with low to moderate mercury levels.<\/p>\n<p>Other fish lower in mercury include tilapia, anchovies, salmon, pollock, cod, sole, haddock, hake, whitefish, and scallops.<\/p>\n<p>Fish higher in mercury include shark, swordfish, king mackerel, marlin, tilefish, and bigeye tuna.<\/p>\n<p>3.

For frozen fish, choose packages that are fully sealed and that don\u2019t have tears or large ice crystals.<\/p>\n<p>Opt for lower-mercury fish: Choose fish with low to medium mercury. This helps reduce your mercury exposure, especially if you eat fish often.<\/p>\n<p>Consider your goals: All fish have omega-3s in varying amounts, and their protein, fat, vitamin, and mineral content also vary. If your goal is to get the most omega-3s, choose fattier fish like salmon. If your goal is to <a data-ylk=\"\" href=\"https:\/\/www.health.com\/high-protein-fish-7565426\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">increase protein intake<\/a>, choose leaner fish.<\/p>\n<p>Opt for healthy cooking methods: Grill, bake, or steam fish instead of frying to reduce added saturated fats. Cook fish to 145 degrees Fahrenheit (63 degrees Celsius) to prevent foodborne illness.<\/p>\n<p>Read the original article on <a data-ylk=\"\" href=\"https:\/\/www.health.com\/healthiest-fish-12027685\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">Health<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"When choosing fish, look for those that are highest in nutrients but lowest in mercury.
