Even today, many women believe that diet can influence the sex of their future child.
Scientists do not completely disprove this theory. The results of several studies suggest that low sugar levels more often born female offspring.
The mechanism of influence of glucose in the blood on the formation of the fetus has not yet been studied.
Biologists try to explain the phenomenon with the law discoveries of evolutionary advantage - if the pregnancy is accompanied by disease or nervous tension, is formed girl.
And one little girl has more chances to survive in nature and find a male for procreation than a puny boy.
Some results of the future child's sex is largely dependent on the composition of semen.
Recent studies did not exclude the important role of the mother. It is such that single mothers often give birth to daughters.
If we believe the traditional folk advice, women dream of the son should take more salt and red meat products.
And to a daughter, they need more vegetables, fish and sweet dishes, especially sweets and chocolate.
In favor of such a view, however, no scientific evidence.
