Do pregnant women have to supplement DHA during pregnancy? After pregnancy, DHA really needs to be supplemented, because DHA is what we usually call brain gold, and it is a very important polyunsaturated fatty acid for human body. DHA is an important element for the growth and maintenance of cells in the nervous system, and an important component of the brain and retina.
From the fifth week of pregnancy, the embryo began to differentiate into organs, and the fetal brain began to develop. At this time, the cells rapidly divided and proliferated, from 1 to 2, 2 to 4, 4 to 8, 8 to kloc-0/6. Some cells formed the fetal brain, and the other part formed the fetal nerve tissue, which was also the first peak of fetal brain development.
Therefore, it is very necessary to start to supplement DHA at 10- 12 weeks of pregnancy. If the DHA level in the expectant mother is relatively high, the baby's vision and intellectual development will be relatively good. Therefore, it is necessary to supplement DHA during pregnancy, especially in the early stage of fetal brain development.
How do pregnant women supplement DHA? 1. Deep-sea fish such as sardines, yellow croaker, salmon, saury, swordfish and hairtail all contain a lot of DHA.
Recommended eating method: If pregnant mothers want to retain DHA to the greatest extent, they should mainly steam the fish when cooking, and then stew and fry it. Try not to fry the fish to eat, and it is easy to get angry if the nutrition is lost.
2. The DHA content of algae food such as kelp, laver and seaweed is also relatively high.
Among these algae foods, DHA content is high, EPA content is low, and it is the most natural, with strong antioxidant capacity, which is most conducive to human absorption. It can also be said that DHA is supplemented, and algae foods are the first choice.
Recommended eating methods: kelp sparerib soup, kelp lotus root soup, kelp mung bean syrup and laver egg soup, which are very suitable for pregnant women. Besides DHA, they can also supplement calcium and high-quality protein.
3. Walnut, peanut, sesame, pistachio and other dried fruit foods contain A-linolenic acid, which can be converted into DHA in human body.
Recommended eating method: Dried fruits are generally not easy to digest, and some pregnant women may be allergic. Therefore, pregnant women should eat in moderation when choosing to eat dried fruits, and they can eat a small handful every day, and if they are determined to be allergic, don't.
4. DHA products.
If pregnant mothers are allergic to fish or for other reasons, they can choose DHA supplements. At present, there are two kinds of DHA products on the market, one is extracted from deep-sea fish oil and the other is extracted from algae.
Recommended eating method: pregnant mothers can choose DHA nutrition extracted from algae to eat, but before eating, they should consult the obstetrician to see if it is necessary to supplement nutrition specially to avoid overdose.
The above is the answer to this question, I hope I can help you.
