It is best for pregnant women to take bird’s nest during the first 3 months of pregnancy and the second 3 months of pregnancy, because the first 3 months of pregnancy is the period of rapid embryonic development, and taking bird’s nest during this period can promote the growth and development of the embryo. During the second trimester, bird’s nest is good for the development of the placenta, which is also good for maintaining the healthy growth of the fetus. Bird’s nest is a very good food, it is rich in active protein, fiber, minerals and surface active substances, but processed bird’s nest cannot guarantee the safety of the food. Therefore, if it is consumed by pregnant women, it is recommended to try to choose a better quality product. In addition, the consumption of bird’s nest must be moderate, do not consume too much bird’s nest, and eat seasonal fruits and vegetables during pregnancy to ensure a balanced diet.
