Was King Henry VIII right after all?

Ok, we've all heard the story. Henry the Eight executed his wives because they didn't give birth to sons. This happened even though it was really his fault that he had daughters, since the male determines the gender of the child, right?

But maybe it was his wives' faults after all. A study reported in today's NY Times found that the mother's diet at the time of conception can influence the gender of the child. So was it the wive's fault after all?

Perhaps not. The study found that the mothers who had higher-energy diets tended to have male children: "High levels of glucose encourage the growth of male embryos while inhibiting female embryos." So maybe Henry would have had a son if he had only fed his wife better.
