From the fifth week of pregnancy, the embryo began to differentiate into organs and the fetal brain began to develop. At this time, cells divide and proliferate rapidly, from 1 to 2,2 to 4,4 to 8,8 to 16. Some cells form the fetal brain, and the other part forms the fetal nerve tissue, which is also the first peak of fetal brain development.
Therefore, it is very necessary to start DHA supplementation 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 better. 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 fish when cooking, and then stew and stir-fry. Try not to fry fish, it is easy to get angry when nutrients are lost.
2. The DHA content of kelp, laver, laver and other algae foods is also high.
Among these algae foods, DHA content is high, EPA content is low, and they are the most natural and have strong antioxidant capacity, which is most conducive to human absorption. It can also be said that DHA is supplemented, and algae food is the first choice.
Recommended eating methods: kelp sparerib soup, kelp lotus root soup, kelp mung bean soup, laver egg flower soup, which is very suitable for pregnant women. Besides DHA, they can also supplement calcium and high-quality protein.
3. Walnut, peanut, sesame, pistachio and other dried fruits contain α -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 a small handful of dried fruits every day in moderation, and don't eat them if they are allergic.
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 an obstetrician to see if they need special nutrition supplement to avoid excessive consumption.
