Raphaël Gruman’s point of view. Nutritionist, he developed the nutritional program for MyBuBelly, a natural method for choosing the sex of his baby.
How can the diet of the mother-to-be influence the sex of the baby?
“Studies have shown that Y spermatozoa (male) are more sensitive and therefore more fragile when the vaginal flora has an acid pH. Suddenly, a more acidic vaginal environment will more favor the X spermatozoa (female) to the detriment of the Y spermatozoa. In addition, the body’s pH can be modified by our diet. Based on this observation, if you want a boy, it is better to bet on “alkaline” foods. Conversely, to have a daughter, it is better to adopt an acidifying diet. It would take about two months to change the body’s PH and therefore its vaginal flora. “
In practice, which foods to favor to have a girl or a boy?
“In the boy’s diet, it is advisable to remove all dairy products (milk, yogurts, cheeses, etc.) and oilseeds, in particular. It is better to favor salty foods such as smoked salmon, cold cuts at the rate of one cured product per day. Conversely, in the girl diet, it is recommended to favor dairy products, calcium water, or oilseeds to replenish calcium and magnesium and avoid salty products and pulses, for example. The MyBuBelly method details precisely which foods to favor and which to avoid. “
Is this method really effective?
“Yes, based on feedback from women who have followed the method, the effectiveness is close to 90%! But, on condition of strictly following the diet. And, also taking into account the moments of its cycle to conceive. Because if the sexual intercourse is more or less close to ovulation, there is more or less chance of having a girl or a boy. This method is a natural boost. But of course, nothing is 100% sure! “
Are there any contraindications?
“This diet is contraindicated for women with hypertension, diabetes or kidney disease. In any case, it is better to seek advice from your doctor before starting. We also specify that these recommendations should not be followed for more than six months to avoid deficiencies or excess in certain foods. Because if this diet is correctly structured (each day, there is a protein, vegetables and starches for example), it is intentionally unbalanced in certain nutrients to modify the body’s PH. “
The point of view of Prof. Philippe Deruelle, gynecologist-obstetrician, secretary general of the National College of French Gynecologists and Obstetricians (CNGOF).
How can the diet of the mother-to-be influence the sex of the baby?
“Naturally, a woman has a 51% chance of having a boy and 49% of having a girl in each cycle. Perhaps the diet can modify the pH of the vaginal flora but no study proves this assertion. All the more so, since other factors can influence the vaginal pH such as the period of the cycle, an infection or the taking of antibiotics. “
Is this method really effective?
“There are studies showing that feeding could potentially affect the sex of the baby. But be careful because they are old, most date from the 60s. And above all, none is scientifically serious! They lack methodology. “
Are there any risks?
“You have to make sure you have no medical contraindications before embarking on this type of diet. And, this is not without consequence. Because for example, if a woman removes all foods providing salt, she may indirectly have a risk of iodine deficiency. Indeed, iodine deficiency is very common and one of the best ways to remedy it (if you eat little fish) is to consume salt enriched with iodine. However, during pregnancy the lack of iodine could have a negative impact on the baby’s thyroid and also on his IQ. “
What do you recommend?
“More and more studies are clearly showing that the 1000 day period, namely before and during pregnancy, has a long-term impact on the health of the baby. It would therefore be better to focus on how to have a better diet during these times rather than on how to choose the sex of your child. Of course, this is a legitimate desire on the part of expectant mothers, but the medical profession is more about letting go when a woman is considering pregnancy. And, focusing on the question of the sex of your unborn baby can add a lot of pressure and stress. “
