A new study has linked caffeine with miscarriages.

People who drink more than a little caffeine when they're trying for a pregnancy are more likely to lose that pregnancy early on, the study found. And that goes equally for men or women.

When either men or women drank three or more cups a day of caffeinated drinks before pregnancy — sodas, energy drinks or coffee — the woman was nearly twice as likely to lose that pregnancy early on. And if women consumed more caffeine after they conceived, they were also more likely to miscarry.
