Mothers who ate cereal had a higher percentage of sons.
Want a son? Pack on the calories. Biologist Fiona Mathews of the University of Exeter in England and her colleagues surveyed 740 first-time mothers on their pre-pregnancy eating habits and found that 56 percent of those on high-calorie diets had sons, compared with 45 percent of those on leaner menus...
Sex position also plays a role in determining a baby's gender I remember reading.
This is interesting but I don't think this study is definitive. 600 is a small group and 56% is not a large variation from average. But still, for those who want a son, it may be worth trying.
The 56 percent pertains to mothers who ate more calories. They had 11 percent more sons than mothers who ate fewer calories according to the article. However, the article goes on to say the type of food a mother eats also plays a role. In this case, breakfast cereal plays a large role in determining the gender of the infant.
But it wasn't only calories that contributed; specific foods also appear to play a role, say researchers. "Prior to pregnancy, breakfast cereal, but no other item, was strongly associated with infant sex," the researchers write in the journal Proceedings of the Royal Society B. "Women producing male infants consumed more breakfast cereal than those with female infants."
