What is easy to have a boy? According to scientists' research on food, it is found that some foods are acidic while others are alkaline. If pregnant couples really want to have a boy, then in order to increase the chances of having a boy, women should eat more alkaline foods, because such foods can balance the pH of the human body, make the human body alkaline, and increase the chances of sperm containing Y chromosome successfully combining with eggs.

1, pregnant women need to eat more alkaline food, such as: cabbage, cucumber, carrot, spinach, cabbage, lettuce, taro, kelp, citrus, figs, watermelons, grapes, raisins, strawberries, millet, coffee, wine, natural green algae and so on.

2, pregnant men need to eat more acidic foods, such as: egg yolk, cheese, dessert, sugar, tuna, flounder, cheese, west point, mullet roe, firewood and so on.

It should be noted that from a medical point of view, the pH value of the human body is relatively constant, and it is impossible to have a big deviation depending on which kind of food to eat. There is no scientific basis for saying that drinking alkaline water and eating alkaline food can change the pH of the body and become an "alkaline constitution", which can increase the chances of having a boy. Under normal physiological conditions, the pH of tissues, organs and blood is relatively stable, and there is no such thing as "acidic constitution" or "alkaline constitution" in medicine. For example, the pH value of blood is maintained between 7.35 and 7.45. If the pH value changes, it is acidosis or alkalosis, which is usually a complication of a certain disease and even fatal in severe cases.

Therefore, although pregnant couples can adjust their bodies through diet, improve the quality of sperm and eggs, and increase the success rate of pregnancy, it is difficult to increase the chances of having boys by controlling diet.
