When do pregnant women eat DHA?

Pregnant women's DHA, docosahexaenoic acid, commonly known as brain gold, is a very important unsaturated fatty acid for the human body, belongs to the omega-3 unsaturated fatty acid family of important members. DHA is a major element in the growth and maintenance of cells in the nervous system. It is an important component of the brain and retina. The content of DHA is up to 20% in the human cerebral cortex, and the largest proportion in the retina of the eye, accounting for about 50%.

In general, the best results are obtained in the second and third trimester (after 20 weeks of gestation) until the first 6 months of life. This is when the fetal brain is growing at its fastest rate and requires DHA intake. Therefore, experts suggest that pregnant women from the fourth month of gestation to supplement DHA properly, after the birth of the child, the mother can continue to take DHA, through milk feed to the fetus.

During pregnancy, DHA can optimize the composition of phospholipids in fetal brain pyramidal cells. Especially after the full 5 months of the fetus, if the artificial auditory, visual, tactile stimulation of the fetus, will cause the fetal cerebral cortex sensory center neurons to grow more several processes, which requires the mother to supply more DHA to the fetus at the same time.

DHA plays an important role in the maturation of retinal photoreceptors. In the third trimester of pregnancy, the mother can synthesize DHA from A-linolenic acid in the mother's blood, and then deliver it to the fetus's brain and retina, where the nerve cells mature, which requires the mother to supply more DHA to the fetus at the same time. Thus, the importance of DHA for the fetus.

In addition to getting DHA from food, you can also get DHA from special DHA supplements, but choose these products with caution.

How can pregnant women take DHA

Pregnant women should take DHA supplements after eating eggs, fish, tofu, etc., so that they can fully absorb it. Because DHA in fish oil exists in the form of fat, it can be absorbed by bile in the dodecaena after eating. Generally, after eating food containing protein and fat, biliary secretion will be caused by the nerve reflex on the gastrointestinal mucosa. Therefore, expectant mothers should not be picky about food during pregnancy, and can not rely on nutritional products alone to supplement nutrition. The main source of nutrition should still be ingested from the diet.

Many DHA supplements on the market are fish oil products, which contain DHA and EPA(another omega-3 unsaturated fatty acid). Pregnant women should choose fish oil products that are high in DHA and low in EPA. Since fish oil in Chinese waters contains more DHA than that in the Atlantic Ocean and other waters, domestic DHA supplements contain more DHA and less EPA. Therefore, pregnant women choose domestic products than imported products are more suitable and affordable.

If the human body intakes a certain nutrient for a long time, it is at risk of nutrient deficiency. However, if the intake level exceeds the maximum tolerable intake, the possibility of toxic side effects will increase. The same goes for the essential fatty acids ω6, ω3, and DHA, which is made from essential fatty acids. Excessive DHA and AA can cause side effects, such as low immunity, so pregnant women should reasonably control the intake of pregnant women's DHA supplements.
