Why do patients with hyperlipidemia often eat marine fish?

Fish is easy to digest and has a fresh and tender taste. It is high in protein and significantly lower in fat than meat, so fish dishes are very popular. In addition to the taste, in terms of health, whether it is freshwater fish or marine fish, the cholesterol content is generally not very high, and the fatty acid composition of the fish oil contained in it is also very peculiar, which is manifested as a longer or much longer carbon chain than vegetable oil, and another point, the number of double bonds in fish oil is more than that of vegetable oil.

Two special fatty acids have been found in fish oil: one is eicosapentaenoic acid (code name EPA) and the other is docosahexaenoic acid (code name DHA), which has anticoagulant and antithrombotic effects. The cholesterol-lowering effect is much stronger than that of vegetable oil, and the content of this special fatty acid in marine fish is higher than that in freshwater fish, such as mackerel, sardines, saury and other marine fish.

Medical research has proved that eating fish, especially marine fish, has the effect of preventing and treating hyperlipidemia and coronary heart disease. Atherosclerosis and coronary heart disease are most common in Europe and the Americas, least common in Japanese in Asia, and almost no in the Arctic Eskimos.

Compared with the residents of Europe and the United States, the biggest difference is that the eating habits of the residents of the latter two regions are to eat more marine fish. European and American residents eat an average of 20 grams of fish per day, Japanese people eat 100 grams of marine fish per day, and Eskimos eat 400 grams of marine fish per day. Eskimos living in the Arctic region, whose ancestors lived by fishing and hunting, often ate a large amount of raw marine fish, and found that the content of high-density lipoprotein (HDL) and eicosapentaenoic acid (EPA) in their blood were significantly increased. They also have relatively low rates of hyperlipidemia, coronary heart disease, hypertension, and diabetes.

Coincidentally. According to relevant domestic data, the census of coronary heart disease in China also shows that the prevalence of coronary heart disease among fishermen in Zhoushan Islands is the lowest in China. Therefore, people with hyperlipidemia should eat fish often, especially a variety of marine fish, which can indeed reduce and prevent the occurrence of coronary heart disease.

Eat for reasons.

For high blood lipids, you can eat fish in moderation. Fish meat is rich in protein, inorganic salts, vitamins and other nutrients, and its fat is mostly unsaturated fatty acids, which can accelerate fat metabolism and inhibit fat synthesis, and has the effect of reducing blood lipids. When choosing, try to choose deep-sea fish, because the content of 3 fatty acids and taurine contained in marine fish liver oil and body oil is higher than that of freshwater fish, which has a protective effect on the heart and brain, so patients with hyperlipidemia can consume fish meat in moderation.

How to eat fish can be stewed, steamed, boiled in soup, etc., can be paired with tofu, a variety of seasonal vegetables, delicious taste, better taste.

Dietary advice. Hyperlipidemia refers to high blood lipid levels, which can directly cause some serious diseases that endanger human health, such as atherosclerosis, coronary heart disease, pancreatitis, etc. It is divided into primary hyperlipidemia and secondary hyperlipidemia, which is related to genetics, diet, drugs, diabetes, hypertension, age, alcohol consumption, smoking and other factors. In daily life, the adjustment of dietary structure is particularly important.

1. Low-fat diet, excess fat is one of the conditions for the formation of hyperlipidemia;

2. Avoid foods with high cholesterol content, such as liver, brain, heart, etc., so as not to accelerate arteriosclerosis;

3. Low-carbohydrate, low-sugar diet to control total energy intake;

4. Consume more foods rich in fiber, vitamins and trace elements;

5. Drink tea in moderation, strictly prohibit drinking, exercise moderately, and pay attention to controlling the occurrence of complications.

There is no problem with eating fish with high blood lipids, but it is not recommended to eat high-sugar foods with high blood lipids, which can increase the synthesis of fatty acids and lead to very low-density lipoprotein in plasma. In addition, meat, eggs and dairy foods also contain a lot of cholesterol and saturated fatty acids, so it is better to eat as little as possible.

Fish are divided into freshwater fish and deep-sea fish.

Freshwater fish mainly contain more protein. In fact, fish food still contains relatively little fat, so for patients with high blood lipids, freshwater fish such as crucian carp and carp can be eaten appropriately.

There is also a category of deep-sea fish, now with the improvement of living standards, deep-sea fish are more common in supermarkets, such as salmon, cod, flounder, these are deep-sea fish. Deep-sea fish contains fat, but the fat contained in it is actually a kind of fat that is beneficial to the human body, in fact, it also has a regulating effect on high blood lipids in the body, so for deep-sea fish, patients with high blood lipids can also eat it.

Because marine fish is rich in protein and unsaturated fatty acids, it has the effect of lowering cholesterol and is beneficial to the heart and blood vessels, it is recommended that the elderly eat scaly marine fish more than twice a week; The second is that there are scaly fish grown in rivers, and freshwater fish or captive-bred fish are also OK, although the protein content is not as high as that of marine fish, but the fat content is also relatively small. Finally, people with high blood lipids should try to eat less mollusc fish such as squid and cuttlefish, because mollusc scaleless fish contain relatively high cholesterol, so try to eat as little as possible.

It is also possible to eat fish with high blood lipids, but if you have high blood lipids, you must pay attention to low salt in your diet and eat as little high-fat and high-calorie food as possible.

Yes, fish is a relatively healthy food, the fat content of white meat is small, and it is also a relatively high-quality protein, but it is best not to eat the fatty parts of the fish skin and belly, because the fat content is higher.

Patients with high blood lipids can eat fish, especially some deep-sea fish. Some deep-sea fish can have the effect of lowering blood lipids. In addition, patients with high blood lipids should also eat more soy products, which do not contain cholesterol, contain plant cholesterol that can prevent the intestines from absorbing cholesterol in food, and contain lecithin that can make cholesterol not stagnate on the blood vessel wall to form arteriosclerotic plaques, and soy protein can significantly reduce the levels of serum total cholesterol, low-density lipoprotein and triglycerides.

High blood lipids can eat fish Fish is rich in high-quality protein and a variety of vitamins, inorganic salts and essential trace elements, in the past there was a misunderstanding, that coronary heart disease patients, hyperlipidemia patients can not eat marine fish and scaleless fish, the basis is that this kind of fish cholesterol is very high, this is not accurate, in fact, every 100 grams of food contains only 108 mg of cholesterol, as hyperlipidemia, coronary heart disease patients to eat fish is completely suitable, no need to be classified as contraindications.

Patients with hyperlipidemia can eat some fish appropriately, generally speaking, deep-sea fish has a higher quality of its nutrients and its meat protein. Deep-sea fish contain a variety of beneficial elements and contain relatively little fat.

Patients with hyperlipidemia are suitable for eating fish with light meat and less fat. Deep-sea fish can be a better choice, and now there are studies that show that deep-sea fish contain some good fatty acids, which are also helpful in controlling blood lipids or alleviating some cardiovascular and cerebrovascular diseases, so patients with hyperlipidemia can eat fish.

It is possible to eat fish when you have hyperlipidemia, but it depends on the amount of food eaten and the degree of blood lipids. If the blood lipids are particularly high, it is necessary to avoid eating high-calorie foods, fish is relatively less fat and more protein, and it is okay to eat a little moderately. But you must pay attention to the cooking method of fish, for example, fried fish or braised fish is not suitable for eating, at this time, it is suitable to choose steamed or boiled, then its fat content will be significantly reduced, and it is okay to eat some fish appropriately.
