Bird’s nest is a common tonic. The main nutrients are protein and amino acids, as well as trace elements such as calcium and iron, which can regulate the endocrine system, strengthen the body resistance of pregnant women, help replenish the required nutrients, and have certain benefits for the growth and development of the fetus. The iron contained in bird’s nest is useful in preventing iron deficiency anemia in pregnant women. Although bird’s nest is rich in nutrients, eating bird’s nest alone cannot meet the nutritional needs of pregnancy, so you should pay attention to a balanced diet and avoid over-eating bird’s nest. Pregnant women can eat high protein foods such as mutton, beef, lean pork, fish and shrimp, milk and eggs in moderation, and pay attention to eating more fresh vegetables and fruits to supplement various vitamins. If a pregnant woman is found to have iron and calcium deficiency through clinical examination, it is recommended to take folic acid, calcium and iron supplements as prescribed by the doctor to meet the needs of the pregnant woman and the fetus’ growth and development.
