There's something in the fish head that fights aging.

Professor Wang Cunxin, a fish research expert and professor of the Institute of Oceanography of the Chinese Academy of Sciences, said that the fish brain contains a kind of 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." This is an essential nutrient for human beings, which mainly exists in the phospholipids of the brain and can play a role in maintaining, improving and improving brain function. 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. Professor Wang said that other parts of the fish's head have no special value in nutrition. 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 gills is transparent and gelatinous, which is rich in collagen, which can resist aging and repair the body's cells and tissues. 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 endoplasm is more compact and tastes better than other parts of the body, which is the same as the delicious chicken thighs. Moreover, when the fish is heated into a dish, the delicious ingredients in the fish head are released more easily than other body parts, so it tastes more delicious. In addition, when eating fish heads, you should know the source of the fish heads you 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 not eat it. In addition, when cooking fish heads, be sure to cook them well and thoroughly.
