Fan Qiuzhi’s personal language: Dr. Fu, I will be pregnant for 12 weeks next Monday, do I still need to take folic acid?
In May 2016, my country released the "Women’s Dietary Guide during pregnancy".The guide pointed out that pregnancy is the beginning stage of the 1,000 -day opportunity window in the early life. Nutrition is the most important environmental factors, which will have a vital impact on the recent and long -term health of both mothers and children.
Children are the crystallization of love. Bringing life is a wonderful journey. Pregnant mothers must adapt to changes during pregnancy with a positive attitude and enjoy this process happily.The female dietary guide for pregnant mothers should supplement the following 5 contents on the basis of the general crowd dietary guide: (1) supplement folic acid, often eat iron -rich foods, and choose iodized salt;Ensure foods that contain necessary amounts of carbohydrates; (3) increase the intake of milk, fish, poultry, eggs, and lean meat in the middle and late pregnancy;Tobacco and alcohol, nourish new life and actively prepare breastfeeding.
What is the folic acid?Pregnant mothers on the earth know that folic acid is also known as vitamin B9, which cannot be synthesized in the human body, and can only be taken through exogenous intake.Folic acid supplementation during pregnancy can prevent fetal nerve tube defects (NTDS, also known as neural tube deformity).
In addition to preventing neural tube malformations, folic acid also has very important to prevent high -class cysteine, promoting erythrocyte maturity and hemoglobin synthesis.The intake of folic acid during pregnancy should reach 600 µg -dietary folic acid perfunction (DFE). In addition to eating folic acid rich foods, it should also supplement 400 µgdfe/d.
It is appropriate to supplement folic acid 1 month, 2 months or 3 months before pregnancy?
The differentiation of the embryo nerve tube occurs 2 to 4 weeks after fertilization, that is, 4 to 6 gestational weeks, and the little master realizes that he is usually pregnant after or later or later.It is undoubtedly too late.
Studies have shown that after 4 weeks of supplementing 0.4 mg of folic acid daily, the state of folic acid in the body has been improved to a certain extent, and the concentration of serum or plasma folic acid after 12 to 14 weeks will reach an effective level and stability.
Therefore, most countries suggest that they must supplement folic acid every day from 3 months before pregnancy to ensure that the embryo has a better folic acid nutritional state in the early days.
Is it feasible to supplement folic acid alone?
There are indeed many foods rich in folic acid, including animal liver, eggs, beans, yeast, green leafy vegetables, fruits and nuts.However, the folic acid in natural food is a variety of derivatives of tetrahydrof folic acid, all of which are transmitted, which is easy to decompose for cooking or heat, and the biological utilization rate is low.Okay, high biological utilization.
Therefore, in addition to eating foods rich in folic acid during pregnancy, women should also supplement 400 μg/d to meet their needs.Make sure you take 400 G various vegetables every day, and more than 1/2 of them are fresh green leafy vegetables, which can provide about 200 μgdfe with folic acid.
In other words, pregnant mothers should take 400 μg/d orally during pregnancy, and take 200g of green leafy vegetables per day.
In 2015, the International Obstetrics and Gynecology Alliance (FIGO) published practical suggestions on adolescent and childbearing for young people and childbearing age in "International Obstetrics and Gynecology Magazine".
For women during pregnancy: FIGO strongly recommends preparation, nutritional consultation and intervention as soon as possible, and timely treatment of diseases that endanger pregnancy endings.
Suggestions on folic acid: Folic acid and vitamin B12 must be supplemented in the early pregnancy to prevent the occurrence of fetal nerve tube deformities.Those who take before pregnancy should be taken during pregnancy to prevent giant cellular anemia.Folic acid, vitamin B12, vitamin B6 and choline are all methyl -based donors in the process of DNA methylation. If the mother lacks these nutrients in the diet, it will have a long -term impact on the health of the child.
