How many times a week pregnant women eat bird’s nest is related to the period of pregnancy. Generally, pregnant women should eat bird’s nest 2-3 times a week in early and late pregnancy, and 4-6 times a week in mid-pregnancy. The main purpose of consuming bird’s nest in early pregnancy is to relieve the pregnancy reaction and to achieve the effect of pregnancy and nutrition, while the main purpose of eating bird’s nest in late pregnancy is to replenish the strength for the birth. Usually, 2-3 times of bird’s nest a week in early and late pregnancy can achieve the corresponding purpose. During mid-pregnancy, the fetus is gradually developing and needs a lot of nutrition to ensure the development of the fetus, so it is appropriate to eat bird’s nest 4-6 times a week during mid-pregnancy. If a pregnant woman eats bird’s nest too often during pregnancy, it may lead to an oversized fetus, which is detrimental to the birth and over nutrition of the pregnant woman. In addition, pregnant women should be careful not to use Chinese herbs to stew bird’s nest, but to use fruit or original stew, and to take it with rock sugar.
