Black sesame can be consumed by pregnant women throughout pregnancy without specific requirements. However, it is usually recommended to start consuming black sesame around the fourth or fifth month because the fetal hair starts to grow. Black sesame is rich in fatty oils, folic acid, protein, phosphorus, potassium and other nutrients, which provide sufficient nutrients for pregnant women to nurture their fetus. The natural folic acid in black sesame seeds can effectively prevent fetal malformations, and its oil content can prevent constipation during pregnancy, so pregnant women can consume black sesame seeds throughout pregnancy. However, because fetal hair begins to develop in the fourth or fifth month, the intake of black sesame seeds at this time is beneficial for the formation of fetal hair. However, pregnant women should be careful not to consume too much black sesame during pregnancy as it may cause bloating and indigestion. In addition, pregnant women who suffer from diarrhea or rapid weight gain should also avoid black sesame. In addition, pregnant women should also pay attention to rest, balanced nutrition, maintain a good mood, regular pregnancy tests, and if there is any discomfort, should promptly go to the hospital for examination.
