What nutrition does IVF need? IVF refers to an embryo conceived by a woman outside the uterus during in vitro fertilization. The health and development of IVF babies need reasonable nutrition supply. The following details the nutrition required by IVF from four aspects: embryonic development, nutrition during pregnancy, mother's body and breast feeding.

1. Nutrient requirements during embryonic development In the embryonic development stage of IVF, nutrition plays a key role in cell division and organ formation of the embryo. The following are the main nutrients required for the embryonic development stage. First, protein: the cell wall of an embryo is mainly composed of protein, so protein is an important nutrient for embryonic development. Foods rich in high-quality protein include fish, poultry, beans, etc. Second, folic acid: folic acid is an essential nutrient for DNA synthesis, which can prevent embryonic neural tube defects. Pregnant women can eat enough folic acid by eating green leafy vegetables, beans, nuts, etc. Third, iron: iron is an important component of embryonic hemoglobin synthesis, which is crucial to the blood circulation and oxygen delivery of the embryo. Pregnant women can take in enough iron by eating lean meat, eggs, red dates, etc.

2. Changes in nutritional requirements during pregnancy The nutritional requirements of IVF during pregnancy are similar to those of natural pregnancy, but there are some unique changes. First, the energy demand increases: IVF mothers need additional energy to support the development of embryos and their own bodies. The recommended energy intake varies according to different stages of pregnancy, but it usually increases by about 300 to 500 kcal compared with that before pregnancy. Secondly, the demand for calcium is increasing: the demand for calcium for bone development of test tube babies is high. High quality calcium sources include milk and dairy products, tofu, cheese, etc. Finally, the demand for folic acid and vitamin D increases: folic acid can prevent prenatal neural tube defects, and vitamin D can help the calcium absorption of fetal bones. Pregnant women can get enough folic acid and vitamin D by eating eggs, liver, vegetables, and exposure to the sun.

3. Nutritional requirements of mother's body IVF mothers need to pay special attention to their own nutritional needs during pregnancy in order to provide adequate nutrition for embryos. First, dietary fiber: pregnant women often suffer from constipation, and proper intake of dietary fiber can alleviate constipation symptoms. Dietary fiber is rich in whole grains, fruits and vegetables. Secondly, probiotics: appropriate probiotics intake can help maintain the balance of intestinal flora and improve the function of digestive system. High quality probiotics can be obtained through yogurt, fermented food or dietary supplements. Finally, omega-3 fatty acids: omega-3 fatty acids contribute to the development of embryonic nervous system and visual system. Pregnant women can eat enough omega-3 fatty acids by eating deep-sea fish (such as salmon), flaxseed, etc.

4. Nutritional requirements of breast feeding For IVF mothers, breastfeeding is the best way to feed. In order to ensure adequate nutrition of breast milk, mothers need to pay attention to the following points. First, drink more water: sufficient water intake can promote the secretion of breast milk and discharge metabolic waste. It is recommended to drink 2-3L of water every day. Secondly, a balanced diet: a reasonable combination of protein, carbohydrate, fat and other nutrients, and a rich diet will help to provide adequate breast milk nutrition. Finally, avoid excessive fatigue: the secretion of breast milk is affected by the mother's physical and mental state. Mothers need to ensure adequate rest and avoid excessive fatigue to promote milk secretion. In conclusion, IVF needs nutrients such as protein, folic acid and iron during embryonic development; Pregnancy requires additional energy, calcium, folic acid and vitamin D; Mothers need to pay attention to dietary fiber, probiotics and omega-3 fatty acids; Breastfeeding needs to drink more water, eat a balanced diet and avoid excessive fatigue. Scientific and reasonable nutrition intake can provide a strong guarantee for the healthy development of IVF.
