Miscarriage? It's Your Fault.

A new study published in the American Journal of Obstetrics & Gynecology, finds that pregnant women who consume 200 milligrams or more of caffeine a day — the amount in 10 ounces of coffee or 25 ounces of tea — may double their risk of miscarriage. Spurn that supersized Starbucks. If not, you could be, you know, miscarrying your pregnancy.

But here's the thing. Miscarriage is actually complicated. No-one can really tell you why you miscarry. Most likely, it probably isn't your fault, unless you're a meth-addled alcoholic. And as a doctor friend has observed over the years, those women always seem to be pregnant and having babies just fine.

As The New York Times put it:

Dr. Carolyn Westhoff, a professor of obstetrics and gynecology, and epidemiology, at Columbia University Medical Center, had reservations about the study, noting that miscarriage is difficult to study or explain. Dr. Westhoff said most miscarriages resulted from chromosomal abnormalities, and there was no evidence that caffeine could cause those problems.

What are more direct factors? She says smoking, chlamydia and getting pregnant when you're old. Makes me want to suck down a capuccino right now.
