Advantages and disadvantages of men often eating fish. I believe there is no one who doesn't like eating fish, because fish is not only nutritious, but also contains protein needed by human body. Eating fish can supplement protein and regulate human metabolism. The following are the advantages and disadvantages of men often eating fish.

Advantages and disadvantages of men often eating fish 1 efficacy and efficacy of fish

1, reduce cholesterol: fish has a low fat rate, which is generally not easy to exceed 4%, and contains all unsaturated fats, and the carbon chain of unsaturated fats is long, so it can inhibit the activity of cholesterol-producing rate-limiting enzymes to reduce the cholesterol level of blood cells and then regulate the cholesterol metabolism of the body, thereby reducing cholesterol and improving cytoplasmic permeability.

2, protect the brain to protect vision: fish contains DHA, which is the golden brain of everyone's alias. So far, biologists have not found any animal or plant on land with this substance, so far it can only be found in freshwater fish and shellfish. DHA is an important component of cell growth and maintenance in the central nervous system, and also an important component of cytoplasm in the brain and macular.

The composition in the cerebral cortex of the body reaches 20%, and it often accounts for a large proportion in the macula of both eyes, accounting for about 50%. Therefore, it is essential for the growth and development of infants' brains, for maintaining all normal brain functions of adults, and for preventing cognitive decline and sporadic Alzheimer's disease in the elderly.

As we all know, DHA is more easily digested and absorbed by the human brain than other ingredients, and its metabolism in the human brain is also very fast, so it is very necessary to eat fish often.

3. Prevention of cardiovascular diseases: Fish contains rich and colorful magnesium, which is basically involved in the whole process of basic metabolism in the body, and its composition is second only to potassium in somatic cells. Therefore, magnesium is one of the indispensable mineral elements for human body.

Modern scientific research has also confirmed that magnesium has a key buffering effect on heart activity. According to the inhibition of the heart, weakening the regularity and excitability transmission of the heart is beneficial to the rest of the left ventricle and the heart, and can protect the heart from damage when the blood supply is suddenly blocked, thus reducing the sudden death rate of heart disease. In addition, magnesium can reduce cholesterol in blood, avoid arteriosclerosis, enlarge coronary artery and improve blood supply to the heart. So eating fish often can supplement magnesium in the human body.

4. Prevention of thyroid diseases: Fish is also beneficial to the stability of minerals in the human body. Fish is rich in iodine, which can promote the air oxidation of microorganisms, the formation and dissolution of protein, the decomposition of fat and the digestion and absorption of vitamins. It can be said that iodine participates in many overall metabolic processes in the body.

What if I get stuck eating fish?

Although the fish is delicious, I can't put it down, but there is still a great distress: what should I do if I get stuck eating fish? Many people know that some time-honored brands swallow white rice, vegetables and fruits, spit and drink vinegar. In fact, it is very dangerous to do that. Generally, the most vulnerable places for cardholders to be stabbed by fishbone are tonsil fossa, epiglottic valley, tongue and pear-shaped fossa. The neck and chest are lined with large blood vessels to maintain life, and every gap is crucial.

If the fishbone causes infection or penetration in the relative position, it is likely to be seriously life-threatening. If the fishbone gets stuck, let someone shine it with a strong flashlight first. If you can see it, and the fishbone is not stuck deep, you can use medical tweezers to clip it up. If you can't see the fishbone or have a strong pain, you should go to the hospital immediately and let the doctor do a professional solution instead of forcing yourself. This is not sensational. Indeed, many people are in danger because of forced swallowing, which leads to the rupture of blood vessels.

What if you are allergic to fish?

Generally speaking, it is recommended that patients with skin allergies should eliminate allergens. However, nutrition experts have found in scientific research that onions, garlic, broccoli and oranges contain anti-infective compounds, which can prevent allergic attacks. Broccoli and citrus have the most obvious practical effects. You can try to match these four things with fish. You can also find a professional doctor to treat skin allergies.

Contemporary pharmacology defines fish as fat meat, and other livestock meat products as pointed meat.

Patients with exudative diseases had better not eat fish during the repair period, because EPA carried by fish can inhibit platelet coagulation, which is very easy to aggravate bleeding.

Common problems in eating fish

Although fish is a delicious and nutritious food, people who eat fish should pay attention to some things: at first, you don't have to eat fish on an empty stomach, but you'd better eat it with cassava starch of white rice. Because freshwater fish contains rich and colorful bleaching substances, it needs starch food to dissolve, and it is not easy to deposit a large amount of bleaching substances in the body, reducing the chance of gout;

Secondly, sashimi is a very popular way to eat now. Although sashimi can produce more pleasure in taste, many sashimi contain a kind of sparganium, the full name of which is liver sucking worm.

Advantages and disadvantages of men often eating fish 3 First of all, people who often eat fish will receive these four benefits:

Promote brain development-not only pregnant women, baby mothers and minors, but everyone should eat fish. According to the dietary guidelines of China residents and the US Food and Drug Administration, 300 ~ 500 grams of aquatic products should be consumed every week.

For expectant mothers, fish intake can not only meet the daily nutritional needs, but also be very beneficial to pregnant babies and promote their brain development. For others, eating fish in middle-aged and elderly people may also play a role in delaying brain aging.

Reduce negative emotions-In a study published in the British Journal of Epidemiology and Community Health, in the report "Eating Fish and the Global Risk of Depression", the number of participants exceeded 6,543,800+0.5 million, and both men and women reduced the risk of depression after insisting on eating fish, which was very unfavorable for alleviating negative emotions.

Although the principle is not very clear, unsaturated fatty acids in fish are beneficial to repair brain tissue and stimulate neurotransmitters.

In addition, for menopausal women, omega-3 polyunsaturated fatty acids in fish can also alleviate menopausal syndrome, which is beneficial to inhibit hot flashes, sweating, insomnia and temper tantrums.

Protect the cardiovascular system-Another benefit of eating fish is to protect the cardiovascular system. Especially compared with domestic fish, deep-sea fish has a better effect, and a large amount of polyunsaturated fatty acids is beneficial to all kinds of people.

Reduce the probability of illness-the advantage of eating fish is to reduce the probability of illness. A study on eating fish in the British Medical Journal found that middle-aged and elderly people often eat fish, which is about 25% lower than their peers who don't eat fish. For patients with chronic diseases, it also has certain benefits of stabilizing blood pressure, blood sugar and blood lipid.

Finally, not all fish can be eaten. I advise you not to eat these two kinds of fish!

Big fish: especially pregnant women should not touch big fish, including swordfish and swordfish. The closer they are to the creatures at the top of the natural food chain, the more harmful substances they may accumulate in their bodies. In the case of uncertain safety, it is best not to eat at all to avoid unnecessary threats.

Wild fish: Now more and more people like fishing. Compared with their own fish, more people like to eat different game, either wild mushrooms or wild fish, but the safety of this kind of meat is very low, and it is likely to produce toxic substances because of the living environment and the food they eat.
