What are the benefits of DHA intake by pregnant women to the fetus?
1, promoting fetal brain development.
During pregnancy, dha can optimize the composition of phospholipids in fetal brain pyramidal cells. Especially after five months, if the hearing, vision and touch of the fetus are artificially stimulated, the neurons in the sensory center of the fetal cerebral cortex will grow more dendrites, which requires the mother to supply more dha to the fetus at the same time.
2. Promote the maturation of retinal photoreceptor cells.
Dha not only plays an important role in the development of fetal brain, but also plays an important role in the maturation of retinal photoreceptors. Pregnant women ingest dha during pregnancy and then deliver it to fetal brain and retina, which can improve the maturity of nerve cells.
3. Promote the development of brain cells
In the cerebral cortex, dha is not only the main component of nerve conduction cells, but also the main component of cell membrane formation. Most dha will not be digested by gastric juice, but will directly enter the blood and be absorbed by organs such as liver or brain, while EPA and linolenic acid will not be absorbed. The main reason is that dha can enter brain cells through the blood-brain barrier, while EPA and linolenic acid, two unsaturated fatty acids, cannot be absorbed by the brain through the blood-brain barrier.
Which pregnant women need dha?
1, expectant mothers who lack mineral sources.
We know that the foundation of eugenics depends on the heredity and physical health of both men and women. Most people think they are healthy, but they are not. Many diseases have no obvious symptoms at the initial stage, such as mineral deficiency diseases such as mild iron deficiency anemia. Experts believe that when hemoglobin is below 1 10g/L or at a critical value, iron should be supplemented appropriately. Especially for pregnant women, due to the influence of physiological factors in a special period, the demand for iron in the body also increases, and it is essential to supplement nutrition at this time.
2. Expectant mothers who are picky eaters.
Because everyone's eating habits are different, the diet structure is also different. For example, some people don't like the taste of coriander and fennel, so they always avoid it. But these vegetables are rich in carotenoids, and long-term partial eclipse will lead to vitamin deficiency and malnutrition.
3. Pregnant women with severe vomiting during pregnancy
During pregnancy, some expectant mothers will vomit badly. At this time, in order to ensure the health of the mother and fetus, it is necessary to supplement nutrition. For example, taking some B vitamins and vitamin C can also reduce the discomfort of pregnancy reaction.
