Can folic acid swallow too long lead to obesity in children?

Recently, a study by scientist Sara Pauwels (KU Leuven) revealed that as women during pregnancy to take folic acid too long, the children later have a greater chance of obesity (serious overweight). In this study, 150 pregnant women were studied and after delivery the children were followed for a year.
For years, pregnant women have been advised by the Health Council to take folic acid (vitamin B9). And from the moment they try to conceive to about the first 10 to 12 weeks of their pregnancy. Folic acid reduces the risk of a cleft lip, open backs and open palate in the baby.

Taking folic acid too long

Although women can stop folic acid after 10 to 12 weeks, it appears that many women take it for about 6 months. For example because they take longer to get pregnant or because they take multivitamins where folic acid is also included. This vitamin is taken during the entire pregnancy. According to the scientist, it is better to ensure that you do not take folic acid for more than 6 months. If you are pregnant or want to become pregnant, it is wise to take this into account.

Response from the Dutch Health Council

The Dutch Health Council does not yet see any need to adjust the advice. When women stop taking folic acid in the 10th or 12th week that they are pregnant, there is no reason to be worried. More research is needed before real conclusions can be drawn. In addition, it is advisable to consider whether you need multivitamins during your pregnancy. This is only necessary if you have a deficiency of certain vitamins and minerals.
If you eat healthy and varied foods where you eat enough fruits and vegetables, extra vitamins (in addition to vitamin D and folic acid) are not necessary. If you develop a deficiency, it will always be noticed in time during blood tests.
