Jeremy Laurance writes in an article titled It’s a boy! The science of gender selection (for the Independent):
So it all comes down to the banana. The yellow fruit with the phallic shape – appropriate in this context – is the best dietary aid for intending mothers wanting a boy, according to research published yesterday.
In what they claim is the first scientific evidence that diet influences infant gender, researchers at the Universities of Exeter and Oxford have found that women who consume more calories around the time of conception, and, in particular, eat more bananas, are more likely to have sons. At the same time, those who skip breakfast (and breakfast seems to be key) are more likely to have daughters.
However, the researchers reported that:
In the study, 56 per cent of women with a high-calorie intake had boys compared with 45 per cent with a low calorie intake. As a means to balance your family, this is only a marginal improvement on the 50:50 chance offered by nature.
