Want a child?
A study in the United Kingdom, involving 740 pregnant women who did not know the sex of their baby, they were asked to keep records of their eating habits before and during early pregnancy. Participants were divided into three groups based on number of calories consumed daily during the period of conception.
The results showed that 56% of women in the group with the highest consumption of colorimeter had baby boys, compared with 45% in the group of lower calories.
Women who had children in addition to eating more calories also said to have fed on a wider variety of nutrients, including potassium, calcium and vitamins C, E and B12.
The researchers also found a link between women who had children and who used to breakfast cereals. However, skipping breakfast is now a common habit in the world desarrollado, cuando no se toma desayuno, dicen los expertos, se reducen los niveles de glucosa en el cuerpo, lo que puede conducir al nacimiento de niñas.
Según los científicos en los últimos 40 años ha habido una reducción de cerca de uno por cada 1000 nacimientos anuales, en la proporción de varones que nacen en los países industrializados.
Los investigadores piensan que este estudio podría explicar porqué en los países desarrollados, donde las mujeres jóvenes optan hoy en día por consumir pocas calorías, la proporción de nacimientos de varones está disminuyendo. Además, este mecanismo nos ofrece evidencia de que existe un mecanismo ‘natural’ which gives the mother the possibility to control with diet, the sex of your baby.
Scientists do not exactly know what are the mechanisms that control this process. But research by in vitro fertilization have shown that high glucose levels stimulate the growth and development of male embryos while inhibiting female ones.
Experts say that playing with the diet and eating too many calories is a good preparation for conception. The best thing is to eat a balanced diet, physical exercise and not smoking or consuming alcohol.
The study, conducted by researchers from the universities of Exeter and Oxford, England, published in Proceedings of the Royal Society B: Biological Sciences (Proceedings of the Royal Society B: Biological Sciences).
