Docosahexaenoic acid oil detection

Function (1) Assisting brain cell development DHA is an important component of the brain cell membrane, participating in the formation and development of brain cells, playing an important role in the extension of nerve cell axons and the formation of new protrusions. It can maintain normal physiological activities of nerve cells and participate in the process of brain thinking and memory formation. It may be related to promoting protein synthesis in nerve cells and promoting the growth of nerve cells. Breast milk contains long-chain polyunsaturated fatty acids. In the past, it was believed that infants may synthesize two essential C18 fatty acids into long-chain polyunsaturated fatty acids through elongation enzymes and de unsaturated enzymes. However, because the enzyme system related to infants in the first month of life is not functioning, they cannot synthesize them themselves. Therefore, artificially fed infants miss the main stage of long-chain polyunsaturated fatty acid accumulation in the brain, And some studies have found that breastfed infants have significantly higher cognitive development scores than artificially fed infants. DHA was added to infants who were unable to breastfeed, and the relationship between the physical development rate of infants was compared with the non added group and the breastfeeding group. The results showed that the added group maintained the first place in weight, followed by a height increase from third to second (first in the breastfeeding group), and a head circumference increase to first. The addition of DHA improved the tolerance of infants to formula milk powder. The growth of head circumference is an important prerequisite and external environment for brain development, and it is also the most difficult to grow among various growth and development indicators. The increase in head circumference in the addition group is higher than that in the other two groups, indicating that adding DHA has significant significance in promoting postnatal brain capacity development. Experts investigated the effects of prenatal education and supplementation of DHA on fetal brain development. The prenatal education group and the "prenatal education+DHA group" showed significantly better results in the evaluation of audiovisual directional response items compared to the control group, while the "prenatal education+DHA group" showed significantly better results in the neck muscle active muscle tension (head upright) item compared to the prenatal education group. The above items can reflect the quality of brain neurons, their neural networks, and their functions. Experts are conducting research on whether supplementing exogenous DHA improves memory in college students. The intervention group and control group received DHA capsules and placebo for 30 days, respectively. Before the experiment, two sets of clinical memory scales were used to evaluate the memory ability of the two groups of students, and the difference was not statistically significant; After the experiment, both groups showed significant improvement in memory compared to before. The intervention group showed significantly better improvement than the control group, and the intervention group had significantly higher levels of associative learning, portrait feature recall, total score, and memory quotient than the control group. The relationship between DHA and brain health is very close. Increasing the content of DHA in food helps to increase the level of DHA in the brain, thereby enhancing learning and memory function, promoting the healthy development of the brain and nerves, preventing and treating visual impairment, and preventing and treating Alzheimer's disease. [2] (2) Research on anti-aging effects shows that with aging, the content of DHA in human platelets and red blood cell membrane lipids decreases, while the activity of SOD decreases; After taking DHA preparations for 4 weeks, the content of DHA in red blood cell membrane lipids and SOD activity of 12 elderly people increased. There are also studies suggesting that DHA has antioxidant and anti-aging effects. (3) Improving blood circulation: DHA can inhibit platelet aggregation, hinder thrombosis, decrease blood viscosity, improve blood circulation, and lower blood pressure. It can be used to prevent and treat cerebral thrombosis and lower limb occlusive arteriosclerosis. (4) DHA can reduce serum total cholesterol and low-density lipoprotein cholesterol, increase high-density lipoprotein cholesterol, and treat hyperlipidemia, atherosclerosis, etc. Its mechanism is to increase cholesterol excretion and inhibit endogenous cholesterol synthesis; Change the composition of fatty acids in lipoprotein to increase its fluidity; Reduce serum triglycerides and inhibit the production of platelet activating factor (PAF) by human monocytes. (5) Other DHA can antagonize allergic reactions, prevent and treat allergic dermatitis, bronchial asthma, and alleviate rheumatoid arthritis; Can improve retinal reflex function and prevent visual impairment; Can reduce liver neutral fat and prevent and treat fatty liver; It has anti-cancer effect, can prevent and cure breast cancer and other cancers, and can effectively inhibit tumor metastasis. In recent years, studies have found that docosahexaenoic acid can inhibit the occurrence, growth and metastasis of tumors, enhance the sensitivity of tumor cells to chemotherapy drugs, improve the cachexia status of the body, and extend the survival time of tumor bearing bodies; It can reduce blood sugar and relieve diabetes symptoms. Elderly people often take health products containing DHA, which can restore the degraded brain nervous function and memory to a certain extent. It can be used to strengthen the brain, improve memory and thinking abilities, and has certain therapeutic effects on memory impairment and senile dementia
