Deep-sea fish oil mainly contains unsaturated fatty acids, which is an essential fatty acid for human body. It is beneficial to lipid metabolism, regulates the body's blood lipids and prevents atherosclerosis to some extent. In addition, it can also contain more vitamins a and e.
Deep-sea fish oil refers to unsaturated fat components extracted from deep-sea fish and animals, namely EPA and DHA. Because the nutrition survey found that human health needs unsaturated fatty acids to maintain, and the saturated fat of the social population exceeds the standard, a large number of commercial organizations have developed such supplements. However, there is no authoritative data to prove that the product has the function of treating hypertension, and it is affected by technology, so it needs to be used with special caution.
The concept of deep-sea fish oil is the abbreviation of unsaturated fat in deep-sea fish. Fish oil refers to oil rich in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in fish. The contents of EPA and DHA in common fish are very low. Only deep-sea fish in cold areas, such as salmon and sardines, have extremely high contents of EPA and DHA, while other land animals contain almost no EPA and DHA. Therefore, deep-sea fish was selected to extract EPA and DHA.
Humans mainly take EPA and DHA from fish oil, among which the highest content is marine fat fish, some freshwater fish also contain a certain amount of EPA and DHA, and other animal foods have less content. Plant food does not contain EPA and DHA. EPA and DHA are both unsaturated fatty acids (O-mega 3), and their chemical names are eicosapentaenoic acid (EPA) and eicosahexaenoic acid (DHA) respectively.
Both of them are unsaturated fatty acids, and their molecular structures are very close, so EPA can be easily converted into high density lipoprotein (HDL) in human body to play its physiological functions.
