Do pregnant women need dha supplements? Relevant departments support pregnant women to supplement dha. Many hospitals advise pregnant women to take pure seaweed oil to promote their baby's intellectual development and reduce the risk of premature delivery. Let's share whether pregnant women need dha supplementation.
Do pregnant women need dha supplements? 1 dha is as important as folic acid. Lack of folic acid in pregnant women can lead to premature delivery and congenital disorders. That's because folic acid is necessary for the growth and reproduction of body cells. Lack of folic acid in pregnant women can lead to fetal malformation. Dha is an important substance for fetal brain development. During pregnancy, the dha content in pregnant women is not enough to meet the needs of the fetus, and the vigorous period of fetal brain development is missed. Moreover, dha supplementation is beneficial for pregnant women to reduce postpartum neurasthenia and depression.
With the progress of society, more and more people are exposed to dha. Relevant departments support pregnant women to supplement dha, and many hospitals recommend pregnant women to take pure seaweed oil to promote their baby's intellectual development and reduce the risk of premature delivery.
Function and efficacy of dha
1, reducing postpartum depression
Research shows that 50-75% of women in China experience postpartum depression for a period of time with the birth of their children, and 10%- 15% of new mothers will become very intense, which is called "postpartum depression" in special terms. Postpartum depression will not only seriously threaten maternal health, but also affect the baby's development, leading to emotional disorders and abnormal behavior. Adequate dha can reduce the occurrence of postpartum depression.
2. Extend pregnancy to prevent premature delivery.
Adequate dha supplementation during pregnancy can prolong pregnancy by 1.6~2.6 days on average, which can prolong pregnancy for women at risk of premature delivery.
3, inhibit inflammation
Dha can inhibit the formation of inflammatory precursors, so it has anti-inflammatory effect. Dha can reduce triglyceride and cholesterol in blood and prevent thrombosis.
4. Beauty and anti-aging
Dha also has anti-aging and moisturizing effects, which is very good for female friends and pregnant women. Beauty lovers and mothers should pay more attention to maintenance.
5. Promote 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.
6. 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.
7. 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.
Do pregnant women need dha supplements? 2 dha has side effects.
Pay attention to balanced nutrition intake. When DHA is not deficient, it is not only ineffective to supplement DHA, but excessive intake will also break the nutritional balance needed by the human body and cause side effects, such as low immunity and lipid peroxidation. Of course, babies, pregnant women and the elderly have a positive role under the guidance of nutritionists, so don't worry too much.
Excessive amount can easily lead to lipid peroxidation.
Although dha contributes to the development of intelligence and vision, it is an unsaturated fatty acid. Excessive intake will lead to lipid peroxidation, cell transparency, fibrosis, and even nerve, obstruction and organ damage. Therefore, dha should not be taken in excess, and it is best to take it under the guidance of a nutritionist.
Affect immunity and hematopoietic function
Excessive use of DHA in infants will increase the burden of digestion and absorption and reduce immunity. At the same time, excessive intake of DHA will also have adverse effects on the baby's hematopoietic system, and bring some side effects on platelet formation and subsequent function.
May cause discomfort.
In addition, because DHA can inhibit platelet aggregation and thrombosis, people with hemorrhagic diseases, liver cirrhosis and coagulation dysfunction should properly control the intake of DHA to avoid bleeding or aggravate bleeding. Therefore, when adding DHA, you should take it in moderation according to your own situation.
Management of dha
(1) management method
In fish oil DHA products, DHA exists in the form of fat, which can be absorbed by bile in duodenum after eating. Generally, after eating food containing protein and fat, nerve reflex on gastrointestinal mucosa will cause bile secretion. Therefore, pregnant women should take these nutrients after eating eggs, fish, tofu and other foods, so that they can be fully absorbed.
(2) Administration time
First, fish oil DHA products
The second and third trimester of pregnancy (after 20 weeks of pregnancy)-within 6 months after the birth of the fetus
Generally speaking, fish oil DHA products have the best effect in the middle and late pregnancy (after 20 weeks of pregnancy) to 6 months after the birth of the fetus. Because at this stage, the neurons in the fetal brain center divide and mature fastest, and it is also the period with the greatest demand for DHA. After the child is born, the mother can continue to take DHA and feed it to the fetus through breast milk.
B, a- linolenic acid nutritional products
The best time to supplement α -linolenic acid nutrition from the third trimester (after 28 weeks of pregnancy) to the sixth month after birth is from the third trimester (after 28 weeks of pregnancy) to the sixth month after birth, because at this stage, pregnant women can use α -linolenic acid in maternal blood to synthesize DHA and then deliver it to the fetus through blood or milk. If the baby is more than 6 months old, you can squeeze the oil into the formula and shake it well, and feed it directly to the baby.
