This superstition claims that dietary choices by prospective mothers—or occasionally both parents—can influence the gender of their baby. Common beliefs suggest that eating salty or protein-rich foods (such as red meat or bananas) favors the conception of a boy, while consuming dairy products, sweets, or acidic foods encourages the birth of a girl. Timing meals in relation to ovulation or adjusting body pH through diet are also tactics often mentioned. In some versions, foods high in sodium and potassium are recommended for a boy, while those high in calcium and magnesium are promoted to conceive a girl. The underlying belief is that these nutrients can change the mother’s internal environment or affect sperm selection, though this lacks scientific foundation.
