A new study finds that coffee may have a very negative effect most people don't realize.
Bad news if you’re a coffee lover: a new study indicates that it has one very negative possible side effect.
The study linked caffeine to miscarriages, finding that those who drank coffee were more likely to lose a pregnancy early on, according to a National Institutes of Health statement.
And it applies to both men or women — those who drank three or more cups per day of caffeinated drinks, whether it be coffee, soda, or energy drinks, were more likely to experience a miscarriage.
Scientists aren’t quite sure what it is about caffeine that is linked to pregnancy loss, but there definitely seems to be some sort of a link. Interestingly, women who took multivitamins before getting pregnant were 50 percent less likely to miscarry.
The study examined 344 couples in Texas and Michigan. The couples chronicled every caffeinated drink they consumed during a period they were trying to conceive. They also wrote down consumption of alcoholic drinks and fish servings.
Scientists took urine, blood, saliva, and semen samples to bolster their findings.
“Our findings provide useful information for couples who are planning a pregnancy and who would like to minimize their risk for early pregnancy loss,” the study’s first author, Dr. Buck Louis, Ph.D., director of the Division of Intramural Population Health Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development, said in the statement. “Our findings also indicate that the male partner matters, too. Male preconception consumption of caffeinated beverages was just as strongly associated with pregnancy loss as females’.”
