London, Nov 29 (UNI) Bite in more chocolates and sweets if you desire for a sweet baby girl and eat more chips and burgers if you are longing for a baby boy.
According to a new research carried out by the the scientists of the University of Pretoria in South Africa, mothers taking a sugar-rich diet are more likely to give birth to baby girls as compaxed to the ones taking a normal diet, the Daily Mail reported today.
The research shows that a mother's diet is a key factor in determining child's sex.
After conducting a study on mice, researchers concluded that those with low blood-sugar levels - a good indicator of a sugar-rich diet - produce more female than male offspring and claim that same could be applied on humans.
Researchers gave 20 female mice a steroid, dexamethasone, which kept their blood-sugar levels low.
The sex of their litters was then compared with that of 20 mice on a regular diet.
Those eating normally produced offspring that were 53 per cent male.
But those on the steroid produced litters that were only 41 per cent male.
The results showed that, in mice at least, a diet that is high in sugar can lead to more female offspring.
Professor Elissa Cameron, who led the project, however, said it was unclear how blood-sugar levels affected the sex of the offspring.
Sex is determined by a chromosome contained in the sperm - X for a girl and Y for a boy. Women have two X chromosones.
But diet, in men, can have an impact by altering the proportion of sperm carrying X and Y chromosomes.
The latest research suggested food may affect the environment in the womb, creating conditions which were more favourable to male or female sperm.
She said it also offered a possible answer to a key question in evolutionary theory - understanding the mechanisms through which animals 'select' the sex off their offspring.
