Fatty acid is an important component of fat. Its chemical structure is a long chain of carbon elements. The structure connecting carbon to carbon is called bond, and the connection between carbon and carbon in fatty acids is a bond called saturated fatty acid. All saturated fatty acids are naturally synthesized in the body and do not need to be specifically supplemented from food. If there is a double bond between carbon and carbon, they are called unsaturated fatty acids. The body does not have the conditions to synthesize unsaturated fatty acids, they should be supplied by food, so unsaturated fatty acids are also called essential fatty acids.

The daily intake of EPA and DHA from the diet of coastal residents is higher than that of inland residents. In the general inland population, the amount of unsaturated fatty acids in the body is low.

Deep sea fish oil has been shown to improve the state of fat in the blood

The high concentration of fat (cholesterol, triglyceride, etc.) in the blood is the basis for the formation of atherosclerosis, and lipoprotein cholesterol, which transports fat in the blood, plays a decisive role.

Lipoprotein cholesterol is divided into high-density lipoprotein cholesterol (HDLC) and low-density lipoprotein cholesterol (LDLC). The lower the density of lipoprotein, the larger the particle size. Low-density lipoprotein cholesterol is easy to combine with other components in blood vessels and deposit in the inner wall of blood vessels, so it is called "bad lipoprotein". High-density lipoprotein cholesterol (HDLC) helps lower blood cholesterol, also known as "good lipoproteins." EPA in fish oil can inhibit the action of bad lipoprotein, reduce the adhesion and deposition on the inner wall of blood vessels, and help high-density lipoprotein cholesterol (HDL) remove excess fat from blood vessel walls, so fish oil is also known as the "scavenger" in blood vessels. So taking fish oil can reduce blood fat.

The role of EPA and DHA

EPA- Unblocked blood vessels: helps to keep blood vessels unblocked, prevent thrombosis, prevent stroke or myocardial infarction; Remove the accumulation of fat in the blood, prevent arteriosclerosis and prevent peripheral blood vessel blockage.

DHA- brain puzzle: is the brain cell formation, development and operation of the indispensable material basis, can promote and coordinate the conduction of neural circuits, in order to maintain the normal operation of brain cells. Students and office workers with excessive use of DHA can improve memory, concentration and comprehension, and the elderly with DHA can help active thinking and prevent Alzheimer's disease.

The role of deep-sea fish oil

DHA in deep-sea fish oil is another special unsaturated fatty acid, which is essential for the formation, development and functioning of brain cells. Scientists have found that high levels of DHA in the brain's "neuronal process cells" make it easier for the brain's neurotransmitters to communicate the correct message. DHA's role, therefore, is to promote and coordinate the neural circuits that keep brain cells functioning properly, thus enhancing concentration, memory, and attention.

EPA in deep-sea fish oil is a special unsaturated fatty acid, which is a protective factor beneficial to blood circulation. EPA can assist in removing cholesterol and hardening plaques attached to blood vessel walls, reduce blood cholesterol levels, help to maintain smooth blood flow, inhibit abnormal blood agglutination, prevent thrombosis, and prevent the occurrence of stroke or myocardial infarction.

EPA and DHA also have anti-inflammatory activity that helps fight inflammation. When you have too much omega-6-fatty acids (often found in large quantities in vegetable oils) and not enough omega-3-fatty acids, your body produces chemicals that cause an inflammatory response. The EPA and DHA in deep-sea fish oil balance out excess omega-6-fatty acids, which is why fish oil is often used to improve inflammation such as rheumatoid arthritis.

EPA and DHA are closely related to emotional balance. When the levels of EPA and DHA in the blood are low, the risk of mild to moderate depression is significantly increased. Numerous clinical trials have shown that fish lovers are more positive in the face of difficulties and stress than those who do not eat fish, because fish contains EPA and DHA, which also improve mood.

The side effects of deep-sea fish oil

It is generally safe for most people (including pregnant and lactating women) to consume no more than 3 grams per day without any side effects from deep-sea fish oil. High doses of deep-sea fish oil can make the blood less likely to clot, increasing the risk of bleeding. Possible side effects of deep-sea fish oil include belching, bad breath, heartburn, nausea, loose stools, rashes, and nosebleeds. Taking deep-sea fish oil supplements with meals can often reduce the incidence of these side effects. Certain fish species, particularly sharks, mackerel and farmed salmon, can be contaminated with mercury and other chemicals. Therefore, when choosing fish oil supplements, it is necessary to choose fish oil products with high purity and extracted from pollution-free deep-sea fish. Green sea fish or small deep-sea fish ensure the lowest environmental pollution in the food chain and are relatively safer.
