People are not satisfied with only eating fish, and fish brain, fish lips, fish eyes, fish scales, and fish are all favored. Can you know how much nutrition these things have? Below, I will give you a detailed explanation.
1. Eat nutrition: fish, fish brain
Fish is rich in high-quality protein, easy to digest and absorb; low fat content, low heating energy; also contains calcium, phosphorus, potassium, iodine, zinc, selenium and other inorganic salts, as well as vitamin A, vitamin D and B vitamins. The muscles of fish have dark meat and white meat. Dark meat contains more lipids, glycogen, vitamins, enzymes, and so on. The taste is more ambiguous. Generally, the activity of tuna, mackerel, sardines and other dark meat are more active. ; Silver carp, large yellow croaker, flatfish, etc. are more white meat, lighter flavor.
Fish brain is rich in commonly known as "brain gold" polyunsaturated fatty acids DHA, as well as phospholipids, to help infant brain development, and also have a role in the adjuvant treatment of Alzheimer's disease. However, the brain cholesterol content of fish is high and food intake should be controlled.
2. Eat beauty, eat taste: fish gizzard (fish belly)
Fish bladder contains biological macromolecule collagen protein, which can improve the nutritional status of the tissue, promote growth and delay skin aging. Food fish maw was recorded in "Qi Min Yao Shu" more than 1600 years ago. It is said to be famous as a bird's nest and shark's fin. It is known as the reputation of marine ginseng and is an ideal high-protein and low-fat food. Sea fish have a thicker wall, usually made of dried fish, called a fish belly. The dishes made of fish belly are smooth, delicate and full of texture.
Chen Yusheng said that before eating, fish maw must be soaked in advance. There are two methods, oil and water. The thick fish maw can be made in two ways. The thin fish belly is better. The oil should be kept at a low temperature. When the fish belly is deep-fried and the hand is broken, it can be removed when the cross-section is sponge-like. Pour boiling water, so that it will be softened by immersing it, squeezed out of water, cut into different shapes as needed, and then rinsed with warm water and washed.
3. Eating novelty, eating fun: fish scales, fish eyes, fish lips
Wang Yi said that scales contain choline, which can enhance memory. It also contains a variety of unsaturated fatty acids, which have a certain effect on the prevention and treatment of arteriosclerosis, hypertension and heart disease, and can be used as frozen fish. In addition, Chen Yusheng said that the fish scales of squid and squid have a certain amount of lipids and umami components. They can also be steamed without cooking food, and when they are eaten, they can sip juice and take a little bit of collagen. The fish scales contain 6-thioguanine, an anti-cancer drug, which is of high value and does not have to be shaved when eating.
The fish's lips are mostly made from the skin and associated tissues of the upper lip of squid, shark and squid. The main components are also collagen. It is also one of the eight treasures of seafood, but it is actually not much nutrition. The content of vitamin B1 and DHA in the fish eye is slightly higher, but due to the small amount of fish eyes, the nutritional value is small. There are also fish tails and fish bones. The fish tail is a piece of fish in the tail of the fish. The nutrition is similar to that of the fish body. The fish bone does have the effect of calcium supplementation, but in general, people eat very little, and the shark's fish bone can do. Fish bone meal.
