I'm not so sure I'm buying this one.......

The women didn’t know the sex of their babies, but when researchers reviewed their food plans, they found that moms who consumed more calories of higher quality before conceiving were about 24 percent more likely to give birth to boys than moms who ate less.

Although this part does make sense for me, anyway:
Odds of having a boy were much higher for women who ate at least one bowl of breakfast cereal a day compared to women who ate less than one bowl a week, the study said. Breakfast cereals are usually fortified by vitamins and minerals.
