In a family meal, fish is a familiar food that provides many nutrients. However, there are some types of fish that are not good for your health and should not be bought because eating too much can be harmful to your health.
Bluefin Tuna
Bluefin Tuna is one of the types of fish that is on the mercury contamination warning list. Mercury contamination is very dangerous to health. Mercury is a heavy metal that can cause neurological damage. Eating Bluefin Tuna can lead to mercury accumulation in the body and difficulty in excreting it, leading to poisoning and harmful effects. Especially in children, Bluefin Tuna can cause mercury poisoning, leading to negative consequences for their development. Mercury poisoning not only damages the oral mucosa but also has erosive effects on the digestive tract, kidneys, and blood vessels. It can also cause brain damage in children.
Salted Fish
Salted fish such as dried fish, salted fish are on the WHO’s warning list as the top food group that causes cancer, especially throat cancer. This is because salted fish contains a lot of nitrite, consuming only 0.3 to 0.5 grams of nitrite is enough to cause poisoning and more than 3 grams can cause death. When eating this type of fish, nitrite can react with amino acids to form nitrosamines – a highly carcinogenic substance and one of the 4 main pollutants in food. This substance can increase the risk of gastrointestinal tumors.
King Mackerel
King Mackerel is known as a particularly good source of omega-3 fatty acids and can be part of a healthy diet. However, they are also a high-mercury fish group, which is beneficial but has a high risk of harm. Meanwhile, you can replace the source of omega-3 without the risk of mercury contamination from other types of fish. Therefore, you should avoid this fish, especially for pregnant women and children.
Orange Roughy
Orange Roughy is a rough-textured, orange-colored fish that can live up to 150 years. This has exposed Orange Roughy to many undesirable factors such as mercury over a long period of time. Therefore, you should avoid this type of fish, especially for children.
Catfish
The characteristic of catfish is that it is a scavenger that thrives in dirty places. Therefore, the risk of catfish being contaminated is very high. They have a risk of mercury contamination and various parasites that cause diseases. Therefore, you should also limit the consumption of this type of fish, and when eating, remember to cook it thoroughly.
Ocean Perch
Unlike freshwater perch, ocean perch is classified by the U.S. Food and Drug Administration (FDA) as the most mercury-contaminated fish species because it lives in deep-sea waters (80% of mercury in surface waters has been destroyed by sunlight). This fish species is also a scavenger, contaminated with microbial toxins, so eating ocean perch carries potential harm.
