Women on diet born more girls

DietWomen who diet during conception, or rarely ate breakfast were more likely to give birth to girls, the results of a British study. This is the first scientific evidence that the amount of energy intake is related to the sex of future child, the more it is, the greater the chance the child is male. The scientists from the universities of Oxford and Exeter, this may explain the fact why in most developed countries where more women are on a diet, the number of births to girls surpasses that of boys, a trend is growing slowly – about 1 in 1000 for 40 years. The experts explain this by the fact that perhaps when entering the body of fewer calories, ie lower blood sugar levels, he “relies” this as a signal of lack of food and reacts according to the laws of evolution. Although the sex of children is determined by genes of the father of science is already known that high glucose levels in maternal him “push” the development of male fetuses. The mechanism of this action is still not established. According to British scientists, from the perspective of evolution in such a relationship makes sense: “The male principle in nature is dependent on the physical effort it takes, while women typically leads to a stagnant life. If the mother has enough food sources, and a male offspring, it actually increases the likelihood that the family can be successfully extended to the grandchildren and great-grandchildren than if born a girl. But if times are hard and food does not reach the pattern is reversed – the female offspring at greater length provides a kind.
The results of the study published in the journal Proceedings of the Royal Society B: Biological Sciences
