Shrimp

Shrimp is a small fish that lives in saltwater areas. In Vietnam, the habitat of shrimp extends along most coastal areas from the north to the south.

The US Department of Agriculture states that shrimp is rich in omega-3 fatty acids, protein, vitamins, and minerals. They also contain good fats and cholesterol for heart health.

In July 2019, the US Food and Drug Administration (FDA) ranked shrimp on its list of the best fish.

One reason why shrimp is classified as “clean fish” is because their life cycle is short, so their ability to accumulate toxins in the body is lower than that of other fish species.

Carp

Carp is a large freshwater fish that grows quickly, tolerates high temperatures, and is adaptable, making it a favorite for its delicious taste and nutritional value. However, carp also faces the challenge of not being able to be artificially bred. Firstly, carp is a large herbivorous fish, and its main food is aquatic and free-floating plants. However, it is difficult to provide enough supply of aquatic plants in an artificial breeding environment, which is a challenge for solving the carp’s food problem in artificial breeding.

Secondly, carp has a unique breeding method and requires certain natural environmental conditions for successful reproduction. In the process of artificial breeding, it is difficult to simulate the environment that meets the breeding needs of carp, making reproduction difficult.

Although carp is difficult to artificially breed, it is very rich in high-quality protein, unsaturated fatty acids, and various minerals. Carp is a nutritious fish with soft and high-quality protein, which helps promote muscle growth and maintain tissue repair. In addition, carp is rich in Omega-3 fatty acids, which are good for cardiovascular and brain health.

Marlin Fish

The habitat of Marlin fish is in estuarine saltwater areas and brackish water in large river mouths. This is a relatively familiar type of fish for Vietnamese people.

According to traditional medicine, Marlin fish has the benefits of harmonic gas, improving digestion, and supporting the treatment of chronic colitis. The elderly, weak people, and people who have just recovered from illness can eat this type of fish to improve their health.

Marlin fish reproduces abundantly and has a short life cycle, so they are less prone to contamination by toxins from the environment. Housewives can choose this type of fish to eat regularly because their price is relatively “soft”.

Some notes when eating fish

Limit fried fish

One of the ways to process fish that removes nutrients is frying, especially deep frying. Eating a lot of fried food is associated with an increased risk of heart disease and stroke. According to a study in older women, eating fried fish once a week is associated with an additional 48% risk of heart failure. Therefore, experts advise to prepare fish by baking or boiling to preserve the nutrients in fish.

Avoid eating fish on an empty stomach

Another note when eating fish is not to eat fish on an empty stomach. Because eating fish on an empty stomach can increase the amount of purines metabolized into uric acid, which can cause tissue damage. And tissue damage is the cause of gout. Therefore, to avoid the risk of gout, you should not eat fish when you are hungry. This is a harmful action that we all need to eliminate.

Avoid eating fish while taking cough medicine

According to experts’ recommendations, people who have long-term cough and are using cough medicine should absolutely not eat fish, especially sea fish, as it will worsen the condition and may cause allergies.

In addition, when you are using certain medications such as antibiotics, anti-inflammatory drugs, antihypertensive drugs… you should also avoid fish to help your treatment process recover quickly and ensure your health.

Do not eat raw fish or fish salad

Most fish species are naturally infected with parasites. If you eat raw fish, these parasites will invade the body and cause harm to the liver, causing the liver to be infected with parasites, even leading to liver cancer. In addition, fish can eat eggs that have many external living environments.

When entering the body of animals, the eggs develop into larvae and cysts residing in the internal organs of animals. One of the parasites that fish can be infected with is tapeworm.

If these parasites are not eliminated, they can be transmitted to the human body and reside in the intestines of humans for many years, causing severe abdominal pain, weight loss, and anemia.

Eating fish maw

In folklore, there is a remedy of eating fish maw to cool down, detoxify, enhance vision, help brighten the eyes, reduce cough. Therefore, even though fish maw is said to be bitter to the extreme, quite a few people still insist on “swallowing” it to prevent illness according to the trend.

However, according to scientific research, fish maw provides enzymes but also contains many toxins such as tetrodotoxin, which are harmful to the nervous system, causing fatigue, respiratory failure, and behavioral disorders.

Eating fish maw can also cause poisoning, bacterial infection, acute bleeding, and even death. Therefore, when processing fish maw, avoid breaking it and avoid letting fish maw liquid splatter into the eyes.
