"Doctor, I especially like to eat sour after pregnancy, is it a boy?" First of all, it is clear that the baby’s gender is determined by sex chromosomes. There is only an X chromosome in female eggs, and there are two chromosome in male sperm.: X and y, so the baby is determined by the dad’s chromosome.Therefore, it is impossible to judge the baby’s gender based on the diet preferences of the pregnant mother.
"Then why does my dietary preference change after pregnancy?" Pregnant mothers are sour because of the chorionic gonadotropin (HCG) secreted by the placenta after pregnancy, which can inhibit gastric acid secretion, reduce the activity of digestive enzymes, affect the gastrointestinal and intestinesFunction, which leads to early pregnancy reactions such as nausea and vomiting and decreased appetite.The sour taste can stimulate the secretion of gastric juice, improve the activity of digestive enzymes, promote gastrointestinal motility, increase appetite, and help food digestion and absorption.Therefore, many pregnant mothers prefer sour food during pregnancy.Because personal dietary habits are different, some pregnant mothers prefer spicy food, and think that the hotter appetite, the better.However, spicy food needs to be appropriate. Spicy foods are prone to excessive stimulation of the gastrointestinal tract, which is not conducive to the health of pregnant mothers and the development of the baby.
Praisea is also more conducive to fetal growth and development from the perspective of nutrition.The fetal bones began to form at the 2nd to March, and the main component of the bone is calcium. Acid substances can form calcium calcium deposition in the bones, which is conducive to the formation and development of fetal bones.Three -valent iron is transformed into a binary iron to promote the formation of hemoglobin; vitamin C is a nutrients necessary for pregnant women and fetuses. It can enhance the immunity of the mother. It has an important role in the formation of fetal cell matrix, cardiovascular growth and development of hematopoietic system.Most of the foods rich in vitamin C are acidic.
Therefore, in terms of food selection, expectant mothers are best to have both sour and nutritious foods, such as tomatoes, hawthorn, citrus, jujube and other fresh fruits and vegetables, which can not only improve the symptoms of gastrointestinal discomfort, but also increase appetite and strengthen nutrition.Failure to fetal growth.
