Bird’s nest can usually be consumed in moderation when you are about 3 months pregnant, and can be consumed under doctor’s supervision. Bird’s nest is rich in protein, minerals, fiber, trace elements and unsaturated fatty acids and other nutrients. Since it is affected by the early pregnancy reaction, it can be consumed in moderation at around the 3rd month of pregnancy under the guidance of a doctor, which can provide a wide range of nutrients for the growth and development of the fetus as well as the mother’s body, but care should be taken not to consume it in excess. During pregnancy, it is necessary to have a reasonable and balanced diet to ensure the growth and development of the fetus and the physiological needs of the mother, and to increase the amount of food rich in protein, calcium and iron and other nutrients, as well as to eat more fresh vegetables and fruits, and to carry out a moderate amount of physical exercise under the guidance of the doctor, such as walking, yoga, etc., in order to ensure the appropriate growth of the body and to facilitate the natural delivery of the baby.
