If you take blood thinner or aspirin daily, when taking deep sea fish oil soft capsules, please consult your doctor to avoid overdose, which may cause bleeding or cause hemorrhagic stroke.

Deep-sea fish oil refers to the oils in the deep-sea fish that are rich in EPA (Teracosapentacid) and DHA (Teracosahexaacid). The amount of EPA and DHA in ordinary fish is very small. Only the fish in the deep sea in cold regions, such as salmon and sardines, have very high levels of EPA and DHA, and almost no other animals on land contain EPA and DHA.

EPA: softens and unblocks blood vessels, reduces blood viscosity, promotes blood circulation, prevents thrombosis, and prevents Alzheimer's and stroke;

DHA: can activate brain cells, promote brain development, and improve memory; at the same time, DHA can activate weak retinal cells, improve vision, and relieve eye fatigue;

The omega-3 content can lower blood cholesterol and prevent hypertension, heart disease, arteriosclerosis, and stroke.

Secrets to protect the cardiovascular and cerebrovascular

Because EPA and DHA are susceptible to oxidation, it is better to take them together with antioxidants rich in vitamin C, vitamin E, and carotene, which should be used with caution by children and pregnant women.

Fish oil soft capsule effect

One: Improve blood supply to the brain. Fish oil capsules, rich in EPA and DHA, can effectively prevent platelet aggregation, reduce blood viscosity, enhance the health of the circulatory system, prevent thrombosis, improve symptoms such as insufficient blood supply to the brain, dizziness and headache, and prevent

analysis

The main function of deep sea fish oil is to lower cholesterol and prevent vascular diseases. EPA is called "vascular scavenger", it has the function of channeling and clearing the blood vessels of the heart, thereby preventing a variety of cardiovascular diseases.

DHA is an indispensable material foundation for the development and operation of brain cells, and it can also help to activate weak retinal cells, thereby strengthening the brain, improving vision, and preventing myopia.

In addition, DHA is an essential ingredient in breast milk, which can enhance the immune system. Applicable conditions of deep-sea fish oil include hypertension, high cholesterol, high blood lipids, cerebrovascular disorders, myocardial infarction, arteriosclerosis, glaucoma, cataracts and the like.

The propaganda materials say that the magical effect is confusing to many consumers, but the professional nutritionist's interpretation of it is very different from the boastful claims.

Wu Huawei, deputy chief physician of the Department of Nutrition of the Third Affiliated Hospital of Sun Yat-sen University, said that deep-sea fish oil is equivalent to ordinary vegetable oils. Vegetable oils such as peanut oil, sesame oil, soybean oil, and corn oil contain so-called nutrients in deep-sea fish oil, that is, not much. And fatty acids. Wu Huawei explained that the so-called EPA and DHA are actually the abbreviations of two kinds of polyunsaturated fatty acids, which are abbreviated in English, and it looks like "it's like that".

Instructions reveal secrets

In fact, ordinary consumers do not see the secrets in deep-sea fish oil. Beijing consumer Ms. Xu is a sea turtle person. In the United States, Xu had bought two cases of original deep-sea fish oil produced by an American company; after returning to Beijing, Xu bought another case of the same brand of deep-sea fish oil in Beijing, but inadvertently It was found that the content of the Chinese and English manuals differed greatly. Ms. Xu said angrily that the Chinese manual was nothing out of nothing.

According to the results of Ms. Xu's comparison, the Chinese manual of the brand's deep-sea fish oil is compared with the English manual, which adds a whole paragraph: "Deep-sea fish oil has the function of lowering cholesterol and preventing cardiovascular diseases, and can prevent blood coagulation and thrombosis. Stroke reduces arteriosclerosis and high blood pressure, reduces blood viscosity, promotes blood circulation and eliminates fatigue. Taking this product in the elderly can reduce the possibility of Alzheimer's disease. "Such a statement means that deep-sea fish oil has a curative effect.

A person from the State Food and Drug Administration introduced that the deep-sea fish oil sold on the market are health products rather than drugs, so the effectiveness of publicity is restricted by regulations. Regarding the specific content of the above-mentioned Chinese manual for deep-sea fish oil, relevant persons from the FDA believed that it was an exaggerated publicity.

Another careful consumer compared the Chinese and English instructions of the deep sea fish oil he took, and found that in addition to the effectiveness promotion, the Chinese instructions had three more words: follow the doctor's order. He said that these three simple words are actually intended to mislead people into the box of "this is medicine". In addition, the Chinese manual also missed a sentence "intentionally": daily value not established, meaning "the daily dose is not specified".

On a brand of deep-sea fish oil bottle held by a patient for consultation, Wu Huawei, an expert in nutrition at Zhongshan Third Hospital, found a line of English words meaning "prohibition of domestic sales". Wu Huawei revealed that this is an Australian brand of deep sea fish oil.

He believes that the underlying meaning of this sentence is that there are still many uncertain factors in the product, such as security. "This may mean some hidden dangers, and international and domestic businesses do not rule out the possibility of hiding hidden dangers for commercial purposes." Wu Huawei said angrily.

Eating more can be harmful

"I don't recommend people who come to consult nutrition to eat deep-sea fish oil." Wu Huawei said that deep-sea fish oil does not rule out health benefits, but eating too much may cause damage to the human body.

Wu Huawei said that deep-sea fish oil is actually a kind of fat, a pure polyunsaturated fatty acid, and each kind of fat has a so-called adverse reaction. Therefore, from a nutritional point of view, doctors never recommend that people take only one kind of fat, and Is recommended to consume various types of fat.

For those who have a diet that is biased towards unsaturated fatty acids, such as some vegetarians, nutritionists believe that they should prevent side effects by taking vitamin E or vitamin C appropriately. Taking deep-sea fish oil as a health supplement other than a normal diet will undoubtedly increase the calorie intake in people's diets and is also a bad diet.

Wu Huawei said that the so-called role of deep-sea fish oil propaganda is indeed true, such as softening blood vessels, but the medical community has not come up with a quantitative index for softening. "It's very possible that the so-called effects are not manifested, and side effects such as fat accumulation and peroxidation are manifested."

Mr. Liu, a food chemistry graduate student at South China Agricultural University, believes that the ingredients of deep-sea fish oil appearing in the face of health products have not been verified by clinical trials, and are not the same as general foods. A long history of taking them can prove safe, its effects and toxicity The situation alone is not very credible.

Marine Expert:

"I never pay for deep sea fish oil"

Mr. Yang, who is a student of environmental studies, is the head of the Environmental Monitoring Center of the South China Sea Branch of the State Oceanic Administration. He said that from the perspective of environmental science, the deep sea is indeed less polluting than the shallow one, but the specific situation depends on the location. It is true that there is a lot of credibility in the deep-sea fish oil propaganda in the deep-sea fish oil propaganda. However, it seems that there is no certainty in connection with food. Mr. Yang said that the fish in the sea are swimming and the sea water is also flowing. There is no way to say about the deep-sea pollution and the good quality of fish oil. Mr Yang said he was unwilling to comment more on deep-sea fish oil, but he said he would not spend money on deep-sea fish oil because it was unnecessary.

Nutrition expert: Stability of deep sea fish oil is worth exploring

After detailed information inquiry and research, Wu Qing, associate professor of Food Chemistry Department of South China Agricultural University, came to a conclusion: deep-sea fish oil does have its unique content, the so-called DHA and EPA. However, it is worth exploring whether the existing health products deep-sea fish oil can provide these nutrients to the human body. It is better to buy fish oil directly than fish.

Professor Wu said that in terms of polyunsaturated fatty acid content alone, deep-sea fish is indeed higher than freshwater fish, and the composition of polyunsaturated fatty acids in different fish species is also different. Professor Wu introduced that the chemical structures of DHA and EPA refer to docosahexaenoic acid and eicosapentaenoic acid, respectively. Freshwater fish and vegetable oils are not necessarily available, or their contents are not as good as those of deep-sea fish. For example, peanut oil is mainly composed of twenty-four carbons. Oleic acid, although the same is an unsaturated fatty acid, the composition is different.

However, Professor Wu pointed out that the chemical structure of DHA and EPA, namely eicosapentaenoic acid and docosahexaenoic acid, which are olefinic carbon or carbon double bonds, is unstable and easily oxidized, resulting in low fish oil storage. Air, light, and metal ions during processing can cause their oxidative decomposition.

In order to learn more, we specifically consulted Dr. Gu Yunrong, who returned from the United States as the general manager of Shanghai Zikang Health Products Co., Ltd., she said positively: "In the United States, news has been released," To prevent mercury poisoning-women and children with caution "Deep-sea fish oil", in fact, in the United States market, such domestically popular fish oil health products are not very popular in the United States.

Expert reminder

Since the ditch oil incident caused public outrage on the Internet, the "ace" deep-sea fish oil in consumers' hearts has also fallen into crisis.

It is reported that "deep-sea fish oil" DHA contains EPA, which can cause precocious puberty in children, and many fish oils are made from scraps of fish. Mercury residues generally exceed standards, and their harmfulness exceeds that of trench oil. Wang Dahong, a senior expert in the industry and chairman of the Marketing Committee of the China Health Care Association, disclosed to the Life Times reporter: "Whenever I see someone spending hundreds of dollars to buy so-called imported high-end goods, I think consumers are too innocent. Domestic Most deep-sea fish oils have problems: substandard quality, non-standard products, and even fraud! "

Fish oil hits "import"

On July 10, a reporter from Life Times visited Beijing's largest Shilihe health products wholesale market, and was most impressed by the three phenomena. One is the fire of deep-sea fish oil. It is tied with lecithin and calcium to become the "big goods" in the eyes of wholesalers. Several wholesalers told reporters that such products have always been very popular and are the best-selling. The second is the "noble" status. The reporter visited a total of 7 companies. Wholesale shops, 6 of which claim to be imported from the United States, Germany, Australia, etc., but the production place is written in Kaifeng, Henan, etc .; the third is cheap, a bottle of deep-sea fish oil labeled with the United States "Auchikang", 100 tablets The wholesale price is only 8 yuan. The wholesale prices of other brands are also concentrated at about ten or twenty yuan, but the retail prices are scary, ranging from three times or even ten times higher than the wholesale price.

The quality of these deep-sea fish oils has caused Wang Dahong a headache. "If you want to know how serious the problem is, you may want to first understand its two major raw material sources." Wang Dahong said that in foreign countries, one is extracted from the directional fishing of deep-sea fish such as cod, salmon and other oils. The content of DHA plus EPA is generally 30%, which is called natural fish oil. The other type is miscellaneous fish, which is large in size. It is sorted and sent to the market for sale, and the rest is sent to a feed mill for processing. Fish meal, and then the byproduct oil is made into industrial fish oil. Generally speaking, natural fish oil is safe and reliable, but it is more expensive; industrial fish oil is cheaper, but pollutants such as formaldehyde and heavy metals may be introduced in the production process, which has poor safety.

Wang Dahong told reporters that there are many problems with domestic deep-sea fish oil, the most serious of which is counterfeiting. It is obviously produced by chemical industry but is said to be natural, and it is clearly miscellaneous fish but is referred to as cod. Many ingredients on the market that claim to be deep-sea fish oil may not even be fish. In China, raw materials for fish oil are divided into three levels: food grade, feed grade and industrial grade. Some manufacturers without moral bottom line use feed grade and industrial grade raw materials in order to obtain huge profits. They are processed into soft capsules and sold as food.

The quality of the soft capsules outside the fish oil granules is also very different. The best ones are extracted from beef bones and cowhide, and the worse ones are extracted from pigskin and chicken skin. The worst are some leftovers left over from making leather jackets. "Like 100 yuan fish oil for 8 yuan, it must be fake. The raw material is likely to be a bad salad oil with a fishy smell, and the capsules are likely to be waste leather or recycled rubber." Wang Dahong said.

"Many products that are said to be imported abroad are actually domestically produced, and they have become a foreign product when they are labeled." The other party claimed that the wholesale price of 100 capsules was 22 yuan, and the product was imported from the United States, with relevant national approvals. In the health food inquiry system of the State Food and Drug Administration, the reporter did not find relevant information.

Alaska is hard to find "deep sea fish oil"

When it comes to deep-sea fish oil, most Chinese people think of Alaska. Wang Dahong said that this is actually a marketing concept launched by merchants since 1998. This is because Alaska is relatively cold near the Arctic Ocean, and the deep-sea fish produced there are high in DHA and EPA. However, a survey by the "Life Times" reporter found that it was difficult to find traces of fish oil in Alaska, the "origin" of many fish oils.

On July 12, the reporter saw on the official website of the Alaska Fisheries Development Office that the export of deep-sea fish and other seafood is its main economic force, and fish oil is only a by-product. Fish oil production there is less than 1% of the world's total. Before 1999, the fish oil produced was mainly used for human consumption. After 2000, fish oil was used more in fisheries-added to salmon feed. This reporter also contacted the Alaska Seafood Market Association, which is currently only responsible for the promotion of frozen Alaskan salmon, cod, and crabs in China, and does not involve fish oil products.

A few years ago, "Life Times" reporters went to Alaska for interviews. In Anchorage, a large city, fish oil was not found, and locals have hardly heard of deep-sea fish oil. The reporter saw in the government's International Trade Market Development Bureau that the shelves in the lobby were full of samples of various export products, many of which were fish products, smoked salmon, dried fish floss, caviar ... Again, there is still no "Alaska Deep Sea Fish Oil".

When a reporter asked about fish oil, Tatsuta Tsukata, a Japanese-speaking expert responsible for the research, said immediately: "We have never verified whether the 'Alaska deep-sea fish oil' in the Chinese market is all extracted from fish caught in Alaska. According to Tsukada, most of the fish oil exported from Alaska is in bulk and is marked without any processing. This fish oil can be used as feed additives or other industrial purposes, and is not the main raw material for making capsules. The Alaska Seafood Market Association's business directory lists nine companies that produce fish oil. But according to reporters, most of these companies are not Alaska local companies, some in Seattle and some in California. Several export officials have also speculated that some of the health fish oils on the Chinese market may be processed in other US states or domestically.

Not only is fish oil hard to find, the concept of "deep sea fish oil" has not been recognized by Americans. Fish oil is a very popular health product in the United States. On the website of the national chain Gian Anxi (GNC), a bottle of 180 capsules of salmon fish oil sells for $ 14, and there is often a buy one get one free promotion. Reporters also saw in Wal-Mart, Costco, and other large supermarkets in the United States. Fish oil has many subdivided products according to the source, such as fish oil, salmon oil, cod liver oil, etc., which are never collectively called "deep-sea fish oil." Among several major fish oil brands such as Jian Anxi, none of them claim to be "deep sea fish oil".

Eat fish 3 times a week, better than fish oil

So, does fish oil have health benefits? Yang Yuexin, director of the Food Nutrition Evaluation Office of the Chinese Center for Disease Control and Prevention, and Cheng Yiyong, chairman of the Chinese Nutrition Association, said that the DHA content in Chinese people did not meet the intake requirements. Although fish oil's role in regulating blood lipids and strengthening the brain has been confirmed by many studies, there are no firm conclusions about its ability to lower blood pressure, prevent Alzheimer's disease and vision loss. Wang Xingguo, an executive director of the Dalian Nutrition Society and a nutritionist in the Nutrition Department of Dalian Central Hospital, said that in the current situation of fish oil quality in China, the usefulness of fish oil is useless, and the most important thing is whether the product quality is excellent. To this end, the experts made the following recommendations:

Choose a reputable place of purchase. Wang Dahong suggested that it is best to buy from large reputable supermarkets, shopping malls, or product chains.

Don't be superstitious about imports, you must look at the place of origin. Quality assurance of imported fish oil is only two or three. If the place of origin is a domestic company, it should be more cautious. An industry expert said that he only dare to buy fish oil produced by a domestic company.

Do not buy below 50 yuan. Wang Dahong said that if the company's operating profit is taken into consideration, the retail price of 100-pack fish oil is around 50 yuan, which is more in line with the law of costs. It's best to choose a big brand that not only makes best-selling nutritional supplements such as fish oil and lecithin, but also provides other health products. Judging from the taste, the good deep-sea fish oil is mainly scented, with a bit of fishy smell, but the bad quality will have a more serious fishy smell.

If you eat fish three times a week, you don't need to eat fish oil. Yang Yuexin suggested that eating fish at least three times a week can basically ensure the intake of unsaturated fatty acids, and there is no need to supplement it with fish oil health products.
