Women can consume sea cucumber in moderation during pregnancy to increase their immune system. It is better to consume during this period because of the rapid development of fetal brain nerve cells in the middle and later stages of pregnancy. Sea cucumber contains arginine protein, which is more beneficial for human absorption. Therefore, pregnant women who are in a position to do so can consume sea cucumber at any stage of pregnancy. The fetal brain nerve cells develop faster in the middle and late stages of pregnancy, so sea cucumber is better for fetal brain development. However, attention should be paid to the intake of sea cucumber in moderation, as it is a great tonic and too much of it may cause pre-term abortion. It is usually recommended to eat sea cucumber once a week, no more than 2 sea cucumbers, in order to increase the nutrition of the pregnant woman’s body and promote the absorption of nutrients in the fetus. In addition, during pregnancy, pregnant women should pay attention to balanced nutrition, light diet, proper sun exposure, and more chicken, fish, meat and eggs. At the same time, attention should be paid to maintaining a good mood, paying attention to rest and regular maternity checkups.
