Larger fish such as swordfish, shark,
Puffer fish are the most poisonous fish in the world.
Advice for Fish Purchased from the MARKET: Most fish from the market are healthy to eat and contain important nutrients such as omega-3 fatty acids. However, there are some fish that contain high levels of mercury or PCBs and so should be eaten less or not at all.
Don't eat shark, swordfish, king mackerel, or tilefish (sometimes called golden bass or golden snapper) because they contain high levels of mercury. Eat up to 12 ounces (two average meals) a week of a variety of fish and shellfish that are lower in mercury.
"`Of all the creatures living in the water of the seas and the streams, you may eat any that have fins and scales. But all creatures in the seas or streams that do not have fins and scales--whether among all the swarming things or among all the other living creatures in the water--you are to detest.
Fish is one of the healthiest sources of protein, and tilapia is no exception. Tilapia is packed with vitamins and minerals like choline, niacin, vitamin B12, vitamin D, selenium, and phosphorus. It is also a good source of omega-3 fatty acids, which are healthy fats that your body needs to function.
The Nutrition in Tilapia
It doesn't have the omega-3's that heart-healthy powerhouses like salmon or sardines have. In fact it is very low in fat, with about 3 grams per serving. Because that fat is primarily omega-6, some media reports suggested it was worse than bacon.
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.
Smaller fish—sardines, anchovies, farmed trout, fresh tilapia, arctic char—and bivalves such as scallops, clams, and oysters don't build up as many contaminants as do the large carnivores.
Being bottom feeders and filter feeders, tilapia, basa, and swai will consume any waste or contaminants present in the water. They are generally mass-produced in crowded aquaculture tanks, which can lead to a high level of contaminants in the fish.
Great White Shark
No list of deadly fish would be complete without the great white shark. Great white sharks are the most notorious sharks and are responsible for the highest number of unprovoked attacks on record.
Fugu (or blowfish) is by far the country's most dangerous dish, and it's the one that Shimonoseki is most known for. If improperly prepared, fugu can be toxic to those who consume it, so only registered chefs with special licenses can create meals with this finicky fish.
Some of the best examples of white fish include cod, snapper, flounder, haddock, halibut and grouper. These types of fish are rich in protein as well as important micronutrients, like selenium, vitamin B12, phosphorus and magnesium.
If you are wondering which seafood choices are highest in Omega 3's, look no further than Salmon, Fresh Tuna, Trout, Mackerel, Herring, Oysters, Sea Bass, and Sardines, which all have greater than 500 mg per serving. Omega 3 Fatty Acids are not the only benefit to seafood consumption.
Mahi mahi is a rich source of protein as well as vitamins B3, B6, and B12. Among minerals, it contains some magnesium, potassium, and phosphorus as well as good amounts of sodium and selenium. Eating just a 3-ounce portion of mahi fish will give you about 72% of the recommended selenium amount in your daily diet.
Tilapia that is farmed and raised in proper conditions and adhering to the farming guidelines is safe to eat, as long as it is also stored and handled properly and thoroughly cooked.
Truth: The basis for the study that claims that Tilapia is worse than bacon is the omega-6 content of Tilapia. However, this comparison makes little sense since bacon isn't overly high in omega-6s, either. It's other things in bacon, such as the amount of saturated fat, calories and sodium, that make it unhealthy.
When farms raise the tilapia in proper conditions, they are safe to eat. People should be sure to store it properly and cook it thoroughly before eating.
Farmed Tilapia, on the other hand, usually eat a carefully balanced plant-based diet, which may be supplemented with fish oils to give them extra Omega-3 fatty acids. Their food floats on the top of the water, so they come up to the surface to get it—no “bottom feeding” involved.
