The claim that eating alkaline food can change the sex of a baby is not scientific. Once the fertilized egg is formed, the sex of the fetus is determined by the sperm and cannot be changed, while the mother’s body is only a place where the fetus is developed and shaped, and it is not possible to change the sex of the baby through food or drugs. Moreover, after pregnancy, women should not eat too much alkaline food, otherwise it may cause certain effects on the body, such as causing stomach pain, bloating, heartburn, nausea and so on. It is recommended not to care too much about the gender of the baby, the birth of a boy or a girl is the same, during pregnancy diet needs to increase nutrition, eat more vegetables and fruits, eat more protein-rich foods, such as milk, eggs, beef, etc., and go to the hospital regularly for a maternity test.
