Never mind that the University of Exeter, UK study just published in the Proceedings of the Royal Society B: Biological Sciences [?] shows that higher nutrient, higher calorie diets at the time of conception are significantly linked to having a boy [55/45, roughly]. The real news is that the odds of having a boy "went up sharply" for people eating at least one bowl of sugared breakfast cereal a day.
While the study only focused on women [so typical], I'm sure the results hold for men as well. At least that's what you can tell yourself when you pick up that microwave-sized box of Crunchberries at Costco. Meanwhile, I see this getting immediately out of control in Korea. Just you watch.
