Seafood is good for lowering blood fat, and excessive consumption may increase human cholesterol. Scientists have found that Eskimos suffer from fewer cardiovascular diseases, which is related to their main food coming from deep-sea fish. These fish are rich in polyunsaturated fatty acids, which can reduce triglycerides and low-density lipoprotein cholesterol and reduce cardiovascular diseases. Although the cholesterol content of shrimp, crab, sardines and clams is high, because their saturated fatty acid content is low, and the cholesterol of shrimp and crab seafood is mostly concentrated in the head and egg yolk, as long as these two parts are removed, they will not consume too much cholesterol.

Sea cucumber has the effects of strengthening yang, benefiting qi, moistening intestines, stopping bleeding and diminishing inflammation. Regular consumption is quite beneficial to enuresis and sexual dysfunction caused by kidney deficiency.

Iodine deficiency will not only cause defects or deformities in the development of nervous system, auditory organs and thyroid gland, but also lead to the decline of sexual function and sexual desire. Therefore, middle-aged people should often eat some seaweed foods, such as kelp and Undaria pinnatifida.

Tuna contains a large number of pigment proteins such as myoglobin and cytochrome, and its fatty acids are mostly unsaturated fatty acids, which have the functions of lowering blood pressure and cholesterol and preventing and treating cardiovascular diseases. In addition, tuna can also strengthen yang, dispel wind and dampness, strengthen bones and muscles, and regulate blood sugar.

Squid has high nutritional value. It is rich in protein, calcium, taurine, phosphorus, vitamin B 1 and other nutrients needed by human body, with extremely high content. In addition, the fat content is extremely low. High cholesterol content.

Clean up frequently. Clean up dead seafood in water storage tanks (boxes and cans) in time to avoid the deterioration of water quality caused by the decay of dead seafood.

Observe with your heart. Always observe whether the stored seafood has abnormal reaction and whether the water quality is kept in good condition. If there is any situation, find out the reason in time and deal with it immediately.

Coiling method

Xin seafood

I. Fish, shrimp and crabs

1. Crab: When choosing live crabs, you should pick them up first, and the claws are strong. When selecting sea crabs, all crabs with dark green shells and bright lights are thick and strong; Most crabs with yellow shells are thinner. In addition, you should also choose crabs with strong clamping force, full navel, white abdomen and deep and thick lines. If you encounter crabs with yellow abdomen, shallow and thin lines and light weight, they are not strong enough.

Fresh fish with good quality: bright and transparent eyes, prominent eyeballs, closed gill cover, pink or red gills, no mucus and dirt, no peculiar smell, bright and neat scales, straight fish body, full abdomen, no swelling, firm and elastic meat, and immediately recovered after pressing with fingers; Anal depression.

Stale fish: fish eyes are turbid, eye sockets are sunken, scales fall off, gills are dark and dirty, fish body is soft, bones are separated, fishbones are exposed, there is an odor, muscles are soft, and elasticity is poor or inelastic; Abdominal distension, anal protrusion, etc.

shrimp

Good quality prawns: the head and body are closely connected, and the shell is closely combined with shrimp meat. When you press the shrimp by hand, it feels hard and elastic. The sides and abdomen of the shrimp are white, and the back is cyan (the male shrimp is light yellow), which is shiny.

Inferior shrimp: the head is loosely connected with the body, the shell is separated from the meat, the shrimp body is soft and inelastic, the body color turns yellow (the male shrimp turns dark yellow) and loses luster, and black rings appear between the joints of the shrimp body, but it is still edible.

Shrimp with poor quality: turn around, the body is soft as mud, the shell falls off, and the body color is black and purple. The nutritional value of this shrimp has been greatly reduced. If stored in an unclean environment for a long time, it may be infected with microorganisms such as pathogenic bacteria and should not be eaten again.

sabotage

Live crabs are the first choice when buying crab products. When there are no live crabs to choose from due to the influence of seasons, the following criteria are used to distinguish them.

Good quality sea crabs: the back is blue and the abdomen is white and shiny; Crab legs and claws are stiff, firmly connected with the body and feel heavy.

Defective sea crab: the back is bluish gray and the abdomen is gray; When you hold it with your hand, it feels light and floating, and both sides of the breastplate feel unreal in the shell; Crab legs and claws are loose and fall off when touched.

Sea crabs with seriously poor quality: white or yellowish back and black abdomen; There is nothing on both sides of the head and breastplate: crab legs and claws fall off easily.

2. Squid: The body is complete and solid, preferably pink.

3. Fresh fish: the eyeball is full, the meat is firm and elastic, the gills are bright red, and the scales are intact and fresh.

4. Jellyfish skin: complete and non-porous, with a moist and shiny surface, and it is better to make a sound when biting.

5. Shrimp: fresh shrimp, its shell should be blue-gray, transparent and shiny, and its head is closely connected with its body. If the shrimp shell has turned red and its head is broken, it is best not to buy it. In addition, when buying shrimp, you should also gently pinch it with your hands, and judge the freshness of shrimp by the feel and elasticity of shrimp meat. Fresh shrimp meat is elastic, while stale shrimp meat is often dry and soft. If you encounter shrimp as soft as mud and black and purple, don't buy it. This kind of shrimp has low nutritional value.

Second, shellfish.

In order to reduce food poisoning caused by eating shellfish seafood, it is best to buy fresh shellfish seafood. When shopping, first of all, the shell color of fresh shellfish should be shiny, and the limbs should be hard and elastic. In addition, it depends on whether the water quality of shellfish is clear and whether there is excrement. Secondly, you can touch it with your hand, and it will shrink to choose live and moving fresh seafood. Finally, you should smell it with your nose. If it is the unique flavor of general seafood, it means fresh. On the contrary, if it smells fishy and rotten, avoid buying it.

Frozen seafood

First, seafood is not only delicious, but also rich in nutrients that people like. But when buying seafood, you must "see, move and smell".

A look: Look at the fish's eyes, the eyes are transparent without turbidity, indicating high freshness. See if the gills are close and the surface of the fish is shiny. Shrimp shells should be close to shrimp meat, and the shrimp body should be complete, elastic, shiny and brightly colored. Crabs and shellfish should have shiny shells and hard and elastic limbs. Squid and octopus should have smooth skin, curved claws and clear markings.

The second measure: press the seafood meat by hand. If the meat is firm and elastic and won't sink in, it means it is fresh. Touch the meat noodles again to see if there is mucus. If there is no mucus, it means the freshness is high.
