Matters needing attention when eating fish head

Professor Wang Cunxin, a fish research expert at the Institute of Oceanography of the Chinese Academy of Sciences, said that China has four herring, grass carp, silver carp and bighead carp. Silver carp is also called silver carp or silver carp. there are more silver carp in bighead carp, but the fish heads we usually eat in restaurants are mainly silver carp and silver carp. The reason why these two kinds of fish are used for fish head dishes is that they grow rapidly and can be raised artificially; second, because herring and grass carp mainly eat grass, while silver carp and bighead carp mainly eat plankton, there is naturally more meat than the former two. The head of silver carp, especially silver carp, is very large, accounting for 1 / 2 or more of the whole body, so silver carp, also known as "fat head fish", is famous for its fleshy head.

Professor Wang's answer is not necessarily to say that the head of a fish has a higher nutritional value than other parts of the fish. Generally speaking, fish brains contain the most comprehensive and abundant nutrients, including a fish oil needed by the human body, which is rich in highly unsaturated fatty acids, and its main ingredient is what we call "brain gold," he said. This is an essential nutrient for human beings, which mainly exists in the phospholipids of the brain and can maintain, improve and improve the function of the brain. If the intake is not enough, the brain development of the baby will be blocked. Therefore, there is a saying that eating more fish heads can make people smarter.

However, Professor Wang said that other parts of the fish's head have no special nutritional value. Many people like to eat fish eyes, in fact, the eyeballs are not delicious, delicious is the part around the eyeballs, which may contain some trace elements needed by the human body, but so far there is no final conclusion. In addition, the meat under the fish gills is transparent and gelatinous, which is rich in collagen, which can resist the aging of the body and repair the cells and tissues of the body; it contains plenty of water, so it tastes good.

Professor Wang pointed out that many people like to eat fish head because its meat is more fresh and tender. This is because the movement of the fish in the water is mainly accomplished by the swing of the head, which moves more, the muscles are more compact and tastes good than other parts of the body, which is the same as the delicious chicken thighs.

When we heat the fish into a dish, the delicious ingredients in the fish head are released more easily than other body parts, so it tastes more delicious.

He reminded everyone that when eating fish heads, they should understand the source of the fish heads they eat, do not eat fish heads in areas where the environment is seriously polluted, do not eat fish heads with large heads, thin bodies, and small tails, and do not eat fish heads with cloudy eyes and bulging outward; do not eat spoiled fish and the heads of fish that have been dead for too long. When cooking or eating, if you find that the fish head has the smell of kerosene, gunpowder, almond and other abnormal odors such as ammonia and agricultural medicine, you must discard it and do not eat it because you are reluctant to give up. In addition, when cooking fish heads, they must be cooked and thoroughly cooked before they can be eaten to ensure health.
