Mom's diet may determine the sex of her child

CHICAGO (AP) -- Snips and snails and puppydog tails ... and cereal and bananas? That could be what little boys are made of, according to surprising new research suggesting that what a woman eats before pregnancy influences the gender of her baby.

Having a hearty appetite, eating potassium-rich foods including bananas, and not skipping breakfast all seemed to raise the odds of having a boy.

The British research is billed as the first in humans to show a link between a woman's diet and whether she has a boy or girl.

It is not proof, but it fits with evidence from test tube fertilization that male embryos thrive best with longer exposure to nutrient-rich lab cultures, said Dr. Tarun Jain. He is a fertility specialist at University of Illinois at Chicago who wasn't involved in the study.

It just might be that it takes more nutrients to build boys than girls, he said.

University of Exeter researcher Fiona Mathews, the study's lead author, said the findings also fit with fertility research showing that male embryos aren't likely to survive in lab cultures with low sugar levels. Skipping meals can result in low blood sugar levels.

Jain said he was skeptical when he first heard about the research. But he said the study was well-done and merits follow-up study to see if the theory proves true.

 

The study was published Wednesday in the Proceedings of the Royal Society B, a British medical journal.

The research involved about 700 first-time pregnant women in the United Kingdom who didn't know the sex of their fetuses. They were asked about their eating habits in the year before getting pregnant.
