Omega-3 fatty acid is a long-chain, polyunsaturated fatty acid found in plants and marine organisms. Studies have shown that saturated fatty acids have adverse effects on health, while omega-3 fatty acids, as polyunsaturated fatty acids, have many health benefits. Different types of evidence suggest that the decrease of omega-3 fatty acid concentration can cause mood disorders. Some preliminary research results suggest that it can effectively treat a variety of mental disorders, such as bipolar disorder, schizophrenia and dementia. For pregnant and lactating women, it is a safe and effective treatment.
There are eight sources of omega-3: Antarctic krill, seals (seals), deep-sea fish, purple perilla seed, flaxseed, qiyazi (qiyazi), seaweed, South American oil vine and yak.
Fish / fish oil: it should be noted that only deep-sea fish are rich in omega-3. Unlike other three plant products, fish contain cholesterol. People with diabetes, hypertension and other diseases should consult a doctor before consuming fish oil to supplement omega3. In addition, fish is a common allergen, which will cause allergic reactions in many people, including children. If you are prone to allergic constitution before eating, please consult your doctor. Deep sea fish oil is rich in unsaturated fatty acids such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which can significantly reduce cholesterol and soften blood vessels. Ruan Guangfeng, an expert of China food and nutrition information exchange center, said that EPA and DHA are the main components of fish oil that play a role in health care for the human body. They come from fish fat. The quality of fish oil is marked by the content of EPA and DHA.
Seaweed: the deep-sea rhynchophyta contains Omega-3. Some deep-sea fish ingest omega-3 because they prey on these algae. Because the existing methods of cultivating and extracting seaweed oil do great harm to the environment, it still needs some time to improve and improve in order to realize commercial production.
