Red snapper is very healthy and full of nutritional elements. Red snapper contains: High levels of omega-3 fatty acids. Selenium.
In most fish, the levels are very low. However, some varieties contain high levels of mercury due to their feeding habits or surrounding environment. Commercially sold fish that may contain high levels of mercury include shark (flake), ray, swordfish, barramundi, gemfish, orange roughy, ling and southern bluefin tuna.
Fish with the highest levels of omega-3 include salmon, blue-eye trevalla, blue mackerel, herring, canned sardines, canned salmon and some varieties of canned tuna. Other good sources of marine-sourced omega-3s include barramundi, bream, flathead, squid, scallops and mussels.
Vermilion snapper has a moderate mercury level which makes it safe during pregnancy but it should be limited to once a week at the most, just like red snapper. Yellowtail snapper is another pregnancy-safe snapper but still should be limited to consuming once a week due to the moderate amount of mercury.
White fish has at least as much protein as meat but much less fat. Good choices include King George whiting, flathead and snapper. Plus: It's official – all Australian fish species have now been analysed and every variety has enough omega-3s to be a 'good source'.
Choose fish and shellfish that are lower in mercury such as salmon, trout, tilapia, cod, sole, sardines, shrimp, oysters, and other shellfish. For the most health benefits, choose fatty fish such as salmon, trout, herring, chub mackerel, and sardines. o These fish have healthy omega-3 fatty acids.
Danger to humans
The Reef Stonefish is the most venomous fish in the world. It has thirteen stout spines in the dorsal fin which can inject a highly toxic venom. The venom causes intense pain and is believed to have killed many Pacific and Indian Ocean islanders.
Species of fish that are long-lived and high on the food chain, such as marlin, tuna, shark, swordfish, king mackerel and tilefish contain higher concentrations of mercury than others.
The good news is, it's the saturated fat in food that raises blood cholesterol levels, not so much the dietary cholesterol, and snapper is super low in saturated fat. It's also relatively low in cholesterol: an average serving of snapper, 37 mg of cholesterol; an average serving of shrimp, 190 mg.
HEART HEALTH: Red snapper is rich in Omega-3 fatty acids. Thanks to those fatty acids, The American Heart Association says eating fish regularly may significantly decrease your risk of heart disease, atherosclerosis, and high cholesterol.
Lane Snapper are among the best tasting, with their crustacean-focused diet lending a sweet flavor with firm texture. Although the are on the smaller end of the range, usually around 14 inches, they are abundant on reefs and wrecks.
1. Salmon. Salmon is versatile and one of the best sources of omega-3 fatty acid, which is essential as the body cannot make it on its own so it must be obtained through food. Salmon's also high in protein, with just 200g providing around 44g protein.
Our bodies don't produce omega-3 fatty acids so we must get them through the food we eat. Omega-3 fatty acids are found in every kind of fish, but are especially high in fatty fish. Some good choices are salmon, trout, sardines, herring, canned mackerel, canned light tuna, and oysters.
But is it safe to eat fish every day? “For most individuals it's fine to eat fish every day,” says Eric Rimm, professor of epidemiology and nutrition, in an August 30, 2015 article on Today.com, adding that “it's certainly better to eat fish every day than to eat beef every day.”
Stonefish stings in Australia
The stonefish is the most venomous known fish in the world and stings can cause death if not treated.
Many eel-like fish of the order Anguilliformes have toxic proteins in their blood which has to be destroyed with heat before eating. Moray eels also produce toxic mucus, and can store toxins in their flesh and organs. The giant moray is a reef fish at the top of the food chain.
Eat up to 12 ounces (two average meals) a week of a variety of fish and shellfish that are lower in mercury. Shrimp, canned light tuna, salmon, pollock, and catfish are low-mercury fish. Albacore (“white”) tuna has more mercury than canned light tuna.
Certain nutrients such as Selenium, Vitamin C and E, and Glutathione help with mercury removal. Adding these nutrients in your diet can go a long way in preventing mercury toxicity. Besides, high doses of chlorella, a green algae, has also been proven helpful in reducing body mercury levels.
Firm white fish that are caught around Australia and can be used deliciously and successfully in most recipes include: Barramundi, Snapper, Flathead, King George Whiting, Flounder, Dory, Ling, Blue-eye Trevalla, Coral Trout, Bream, Emperors, Morwong and Mahi Mahi.
Ling, for example, is a good option for kids as it has a mild flavour and very few bones. Other mild-flavoured fish include leatherjacket, flathead, whiting, flounder, sole and dory. Those who like red meat often enjoy tuna steaks as they have quite a meaty texture and flavour and again, no bones.
