Just a reminder.

Scientists already know that in many animals, more sons are produced when a mother has plentiful resources or is high ranking. The phenomenon has been most extensively studied in invertebrates, but is also seen in horses, cows and some species of deer. The explanation is thought to lie with the evolutionary drive to produce descendants. . .

New research by the Universities of Exeter and Oxford provides the first evidence that a child?s sex is associated with the mother's diet. . . the study shows a clear link between higher energy intake around the time of conception and the birth of sons. The findings may help explain the falling birth-rate of boys in industrialised countries, including the UK and US. . .

As well as consuming more calories, women who had sons were more likely to have eaten a higher quantity and wider range of nutrients, including potassium, calcium and vitamins C, E and B12. There was also a strong correlation between women eating breakfast cereals and producing sons.

Breakfast of champions. There are other reasons to eat a good breakfast, ones that apply to everyone.
