Docosahexaenoic acid is an important component of the brain cell membrane, involved in the formation and development of brain cells, plays an important role in the extension of nerve cell axons and the formation of new processes. It can maintain the normal physiological activities of nerve cells and participate in the process of brain thinking and memory formation. . It may be related to promoting the synthesis of nerve cell proteins and promoting the growth of nerve cells.
Breast milk contains long-chain polyunsaturated fatty acids. In the past, infants were thought to synthesize long-chain polyunsaturated fatty acids from two essential C18 fatty acids through elongase and desaturase, but because of the enzyme system involved in the first month after birth. It did not work and could not synthesize itself. Therefore, artificially-fed infants missed the main stage of accumulation of long-chain polyunsaturated fatty acids in the brain, and studies have found that the cognitive development scores of breast-fed infants are much higher than those of artificial-fed infants. Adding Docosahexaenoic acid to breastfed infants and comparing the developmental rate of infants with the unadded group and breastfeeding group showed that the weight of the added group remained at the first place and the length from the third to the second. (No. 1 in the breast milk group), the head circumference rose to the first place, and the addition of Docosahexaenoic acid improved the tolerance of infants and young children to formula milk powder. The growth of head circumference is an important prerequisite for brain development and the external environment of capacity. It is also the most difficult to grow in various growth and development indicators. The growth of the head circumference of the added group is higher than that of the other two groups, indicating that the addition of DHA is important for promoting brain capacity development after birth. significance.
Experts investigated the effects of prenatal education and supplementation of DHA on fetal brain development. The prenatal group and the “prenatal education + Docosahexaenoic acid group” were significantly better than the control group in the evaluation of audio-visual orientation reaction items. The cervical muscle active muscle tension (head erect) project The +Docosahexaenoic acid group was significantly better than the prenatal group. The above items can reflect the brain neural network, the neural network and function between them.
Experts have studied whether supplementation of exogenous Docosahexaenoic acid improves the memory of college students. The intervention group and the control group were given Docosahexaenoic acid capsules and placebo for 30 days. Before the experiment, two sets of clinical memory scales were used to evaluate the memory ability of the two groups. The difference was not statistically significant. After the experiment, the memory of the two groups was significantly higher than that before the experiment. The improvement of the intervention group was significantly better than that of the control group, and the intervention Group association learning, portrait feature recall, total score and memory quotient were significantly higher than the control group.
The relationship between Docosahexaenoic acid and brain health is very close. Increasing the content of Docosahexaenoic acid in food helps to improve the level of Docosahexaenoic acid in the brain, which is beneficial to enhance the learning and memory function, is conducive to the healthy development of the brain and nerves, and is beneficial to prevent and treat vision. Falling is conducive to the prevention and treatment of Alzheimer's disease.
