There is no conclusion yet on what pregnant women eat to make it more likely to give birth to a boy. Scientific research shows that whether a child is a boy or a girl is mainly determined by the sex chromosomes carried by sperm. Although some studies have proposed the idea that food may have an impact on boys and girls, these ideas have not been widely recognized and confirmed. Therefore, when choosing food, pregnant women should follow the principle of a balanced diet to ensure that the nutritional needs of themselves and their fetus are met.
