Folic acid is a type of vitamin, also known as sphenyl glutamic acid.
Folic acid plays a large role in the development of the fetus, can prevent neural tube malformations, hyperhomocysteinemia, promote the maturation of red blood cells and the synthesis of hemoglobin.
Mothers insist on taking an appropriate amount of folic acid every day to effectively prevent fetal malformations, and promote the incidence of major body surface deformities, congenital heart disease, congenital cleft lip and other diseases to be greatly reduced.
It can also enhance their own resistance, reduce the incidence of tumors, and can reduce the pregnancy response during pregnancy, reduce the possibility of high blood pressure in women, and reduce the possibility of spontaneous miscarriage in pregnant women.
According to the "Guidelines for Dietary Nutrient Intake for Chinese Residents", it is recommended that for expectant mothers who are trying to conceive, it is recommended to supplement folic acid with 400ug per person per day. Pregnant women, throughout pregnancy, it is recommended to supplement with 600 ug of folic acid per day, and during lactation it is recommended to supplement 550 ug of folic acid per day.
That is, if conditions permit, it is recommended to start folic acid supplementation from 3 months before the preparation of pregnancy and continue until the end of lactation.
Because the gastrointestinal motility of pregnant women is weakened, the absorption rate of folic acid is not high, so it is better to prolong the time of folic acid supplementation.
For adult women, the maximum tolerateable intake of folic acid given by the Chinese Nutrition Society is 1000 ug, that is, even if folic acid is supplemented, it is not recommended to exceed 1000 ug per day.
Folic acid supplement FAQs Q&A time
1 If you don't want to eat folic acid tablets, can you use food supplements instead?
Although green leafy vegetables, fruits, and animal livers contain a lot of folic acid, but the stability of folic acid is poor, food loss in the process of storage, processing and cooking up to 50% to 90%, especially heating to the greatest damage to folic acid, so through food supplements can hardly reach the standard of 0.4 mg per day required during pregnancy.
It is impossible to calculate the amount provided per day by means of food supplementation alone, and it is impossible to assess whether the fetus has received sufficient amounts of folic acid.
Therefore, foods with high folic acid content cannot replace folic acid supplements, but can only be used as an auxiliary measure to supplement folic acid.
For mothers, the prevalence of anemia in women of childbearing age in China is 20.6%. A reasonable intake of folic acid can make normal red blood cells in the body of the expectant mother and prevent anemia during pregnancy. For fetal babies, folic acid can prevent fetal neural tube malformations and reduce the risk of birth defects.
Once folate deficiency occurs, the consequences are very serious, and it is impossible to make up for this problem by supplementing folic acid, and surgery is also very difficult.
Don't take such risks.
2 Does eating folic acid cause the "great aunt" to be disordered?
Causes of menstrual disorders:
One may be that pregnant women affect the secretion of pituitary hormones due to psychological reasons such as stress or nervousness, resulting in menstrual disorders, and the other may be that endocrine disorders lead to delayed menstruation due to changes in the physiological characteristics of nutrition during pregnancy.
If the menstrual cycle is often disordered, the gynecological routine examination should be carried out in a timely manner, and the treatment of menstrual adjustment can be carried out according to the results of the examination.
3 If you get pregnant without eating folic acid, will it affect the fetus?
This mainly depends on the mother's folic acid reserves. If pregnant women usually pay more attention to the intake of vegetables, of course, it is better. If the usual partial food is more serious, then continue to supplement folic acid immediately after the discovery of pregnancy, while paying attention to ultrasound monitoring of the fetus.
Taking folic acid is mainly to prevent fetal neural tube malformations, but not supplementing is not necessarily a problem, so don't worry too much, if there is neural tube malformations in the obstetric examination to do Down screening and do b ultrasound teratology most can be seen, especially amniocentesis can be accurately diagnosed.
Of course, if you are trying to conceive or are already pregnant, remember that folic acid supplementation is more effective for preventing neural tube defects in your baby.
After all, prevention is more important than anything else.
4 Should men also take folic acid during pregnancy?
Folic acid supplementation is not a woman's patent, and the lack of folic acid by father-to-be will lead to a decrease in semen concentration, weakened sperm motility, and the number of chromosomes carried in semen will also be abnormal, too much or too little.
Not only does this increase the chances of a pregnant mother having a miscarriage, but it can also cause birth defects in newborns, such as Down syndrome, and also increase the risk of cancer as the newborn grows older.
And because modern men socialize more outside, smoking and drinking are inevitable, which leads to many men with bad sperm, if men take some folic acid every day, the risk of sperm abnormalities will be reduced by about 30%.
Therefore, it is recommended that men still need to supplement folic acid during pregnancy.
5 I heard that folic acid supplementation will lead to fetal cessation, is it true?
Taking folic acid in a standardized manner will not cause the embryonic development to stop. There are many reasons for fetal arrest, the most common is the abnormality of the embryo itself, as well as insufficient luteal body function, folate deficiency in the body, chromosomal abnormalities, pregnant women's emotions and so on.
Embryonic quality is not good or reproductive tract deformity, eating or not eating folic acid may be fetal cessation, standardized taking folic acid can reduce the risk of fetal cessation. There are many reasons for fetal cessation, and it does not matter if a fetal cessation is stopped, you only need to adjust your mood and may be pregnant normally next time.
However, couples who have more than two fetal cessations will have to go to a regular hospital to check both genes and chromosomes and other items related to miscarriage.
