Three kinds of "dirtiest" fish, heavy metals and parasites, are often bought and eaten without many people knowing.

The three dirtiest fish are catfish, eel and tilapia.

Although fish is delicious, no matter how we mix it, we must learn to choose good ingredients. Many fish have no nutrition and may contain many parasites. Everyone should pay attention to buying less of this kind of fish. The following kinds of fish should be eaten in moderation.

First of all, catfish

Catfish is considered to be the dirtiest fish in the world. They eat all kinds of food, not only carrion, garbage, but also human and animal feces, which makes their scalp numb. And it is very resistant to sewage, and can even live directly in the sewer. So they have a lot of bacteria and parasites attached to their abdominal cavity.

Second, eels.

The internal organs of Monopterus albus are hidden in the dark, and there are many kinds of parasites inside. According to statistics, there are 22 kinds of parasites infected by Monopterus albus, mainly nematodes and trematodes. Once Monopterus albus is infected with these parasites, they will remain parasitic in Monopterus albus, and some parasites are very resistant to high temperatures. Ordinary cooking is hard to kill.

Third, tilapia

Speaking of tilapia, some friends may be more interested in the taste value and will go directly to the market to buy some tilapia to eat. However, this kind of tilapia has very low environmental requirements. In most cases, it grows directly in some polluted areas of sewers or sewage industry.

So it not only has many parasites, but also contains a lot of heavy metals. Although it tastes delicious, it also contains many harmful ingredients. Don't eat. Buy some tilapia to eat

Which friends are fish suitable for?

In fact, fish is more suitable for middle-aged and elderly people, because there is too much saturated fat in other meats, and fish is rich in protein and unsaturated fatty acids, which can supplement nutrition well.

For teenagers and children in the growing period, it is ok to eat fish in moderation, because fish is rich in various nutrients, so everyone must pay attention to reasonable collocation when eating, and children should also eat some fish.

As long as we pay attention to the choice of ingredients and try our best to ensure the freshness, cleanliness and hygiene of ingredients, we can avoid the risk of parasitic infection.
