Fish heads contain substances that can fight against human aging

Professor Wang Cunxin, a fish research expert at the Institute of Oceanology, Chinese Academy of Sciences, says that fish brains contain a kind of fish oil needed by the human body, and fish oil is rich in highly unsaturated fatty acids, whose main component is what we call "brain gold." This is an essential nutrient for humans, mainly present in the phospholipids of the brain, and it can maintain, enhance and improve brain function. If intake is insufficient, the brain development process of infants will be hindered. Therefore, there is a saying that eating more fish heads can make people smarter. Professor Wang says that other parts of the fish head have no special nutritional value. Many people love eating fish eyes, but in fact the eyeball itself is not tasty; what is tasty is the part around the eyeball, which may contain some trace elements needed by the human body, but so far the academic community has reached no conclusion. In addition, the meat below the fish gills is transparent and gelatinous, rich in collagen, and can fight against human aging and repair body cells and tissues. Many people love eating fish heads because their meat is more tender. This is because the movement of fish in water mainly relies on the swinging of the head; the head moves more than other parts of the body, the texture is tighter, and the taste is better, which is the same reason that chicken thighs are tasty. Moreover, when fish is made into a dish and heated, the umami components in the fish head are more easily released than those in other parts of the body, so the taste is somewhat more savory. In addition, when eating fish heads, you should know something about the source of the fish head you eat: do not eat fish heads from areas with severe environmental pollution; do not eat the fish heads of deformed fish with a big head, thin body and small tail; do not eat fish heads with cloudy eyes that bulge outward; do not eat fish heads from spoiled fish or fish that have been dead too long. If, during cooking or eating, you find that the fish head has abnormal odors such as kerosene, gunpowder, almond, or similar to ammonia water or pesticide, you must not eat it. In addition, when cooking fish heads, you must cook them thoroughly.
