English Reading Practice - 0010 we're robust

The new study, being published Monday in The American Journal of Obstetrics and 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. However, 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. "I think we tend to go overboard on saying expose your body to zero anything when pregnant. The human race wouldn't have succeeded if the early pregnancy was so vulnerable to a little bit of anything. We're more robust than that."
