Being a boy or a girl is random. But research by British scientists has found that there may be a correlation between a baby's gender and the mother's eating habits before pregnancy. But some experts say the findings need to be tested by further research. Before pregnancy, women should eat more bananas and foods rich in potassium, calcium, vitamin C, etc., as well as more alkaline foods, which will increase the chance of giving birth to a boy. Explaining the new findings, scientists speculated that certain dietary habits may result in higher glucose levels in pregnant women, which may be more conducive to the survival of sperm carrying the Y chromosome. Because this type of food can balance the pH of the human body, making the human body appear in an alkaline state, increasing the chance of Y sperm successfully fertilizing and combining with the egg.

Baking soda is sodium bicarbonate, also called acid sodium carbonate. It is an acid salt with the chemical formula NaHCO3. You can use it to make bread, make soda and make fire extinguisher. It is said that taking a few sodium bicarbonate tablets (that is, baking soda tablets) every day will change the pH in the body and increase the chance of having a son. X and Y sperm have different characteristics. X sperm are larger than Y sperm, move slower, and survive longer. X sperm are also more adaptable to the mildly acidic environment in the vagina. So the simplest way is to wash the vagina with soda water to increase the acidic substances in the vagina, so that the Y can run faster and the possibility of giving birth to a boy is higher.
